...hospitals as well as mending cuts and scrapes that people get, targeting kids because they are accident prone. In later years Johnson & Johnson explored other opportunities mainly in the over-the-counter medicinal products. Over the years they have been subject to many lawsuits but the one this paper will focus on is the product liability lawsuit on the DePuy ASR hip implant. DePuy is a company that specializes in orthopedic products and was acquired by Johnson & Johnson in 1998. The metal on metal hip replacement DePuy ASR was approved by the FDA for use by surgeons on patients that were in need of a hip replacement in 2005. (Meier, 2010). The DePuy ASR hip replacement should have a life of at least 10 years. The device was being used on patients, soon after the DePuy dividion of Johnson & Johnson started receiving complaints of the device with the largest spike of complaints in 2009. (Meier, 2010). Many of the complaints resulted in the patient having to receive another hip replacement only a few years after receiving their first hip replacement. The reason the DePuy ASR hip implant didn’t last is because the device is metal on metal and can cause metal debris as the hip is used. ‘This can cause damage to muscles and other soft tissues which results in the replacement of the device.’ (Meier, 2010). The device was tested on a few patients who were not aware they were ‘testing’ and the...

...Chapter 1 INTRODUCTION Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. The word "bionic" was coined by Jack E. Steele in 1958, possibly originating from the Greek word "βίον", pronounced "bion", meaning "unit of life" and the suffix -ic, meaning "like" or "in the manner of", hence "like life". Some explain the word as being formed from "biology" + "electronics". We are entering a new era of technology inspired by lifestyle and healthcare. The human body is a significant application area for technology and, under the research theme of bionics, we are applying the techniques and understanding of engineering to applications which will improve human health. Our research group is a multi-disciplinary team of engineers, clinicians and biochemists, interfacing engineering technologies to biological systems to improve chronic disease management. The team is developing biomedical platforms based on established techniques and leveraging on semiconductor technology to produce a new breed of medical devices. Such examples include silicon β-cells in a bionic pancreas for diabetics, ultra low power solid-state bio/chemical sensors for continuous monitoring, advanced microfluidics for lab-on-chip technologies, neural monitoring and stimulation to enable future diagnostic/monitoring tools, in addition...

...John Smith Dr. Madaro University Physics I Spring 2014 Biomedical Engineering and the Future of Modern Medicine I have always been interested in math and science, but my interest developed into a fascination this year in physics class. I enjoyed being able to apply all of the laws and theories that we learned in class to real-world situations. I liked being able to figure out the distance an object traveled just by knowing the acceleration and speed, finding the vertical and horizontal components of a force, and solving for the coefficient of friction of a surface. I loved that every concept seemed to build on the one before it, and how they all helped me understand the world in a way I never had before. Whenever I think about my future, what I want to study, and how I want to make a living, I always think of engineering- a career that would allow me to develop this fascination with the way the world works and to apply my knowledge to a project that could help improve peoples' lives. I want to go into this field to develop technology that could help cure disease or improve the quality of life of those with serious medical conditions. The concepts of Physics play a crucial part in the everyday work of Biomedical Engineers, specifically in the invention of prosthetic limbs, artificial organs, and improved hearing aids. "The first artificial limbs were stiff and did not have joints that bent like real arms, hands, or legs" (Woods 40). The invention of the artificial limbs...

...Cybernetic Implants One of the things that we will probably being seeing in the future is the development of cybernetic implants. There are a few pros and cons to the development of cybernetic implants. Some of the pros could be increased life span do to less illness, increased economy due to the sales of implants, increased productivity due to increased physical strength, increased security due to most everything financial would be implanted into you so less identity theft, and increased technology due to increased portions of the brain being unlocked from neural enhancements. Some of the cons could be issues such as the religious views on such things. Some religions believe that the use of cybernetic implants for financial transactions to be a form of the mark of the beast and would have no part in such implants. This issue alone could start major riots and divisions in certain states. Another issue could result from the physical enhancement side. There will probably be an increase in crimes such as grand theft auto due to people having increased strength and in essence feeling almost godlike. They will probably be more likely to ignore the laws and think that they are above them. This will also cause those who cannot afford such implants to be at increased risk. The neural enhancements could also cause people to be able to outthink many security systems and be able to develop more homemade devices for crime. There is a lot consider when dealing with cybernetic implants. While...

...Penn Square Bank and the Down Corning Bankruptcy Today’s businesses struggle to survive in a volatile marketplace and frequently internal and external ethical pressures are placed upon employees and management in an effort to ensure the success of the company. Companies like Penn Square Bank faced ethical pressures regarding documentation, credit extension, and revenue recognition, which eventually led to the closing of Penn Square Bank. The Dow Corning bankruptcy raised many ethical questions. Speculations have been made about whether Dow Corning filed bankruptcy because of the financial hardship placed upon it by consumer lawsuits or whether Dow Corning used bankruptcy laws to shield itself from obligations to its consumers. This report will examine, 1) the ethical challenges and pressures each of these companies faced, 2) a review of Dow and Corning’s actions during the bankruptcy filing, and 3) a discussion of how Penn Square Banks ethical pressures might have been alleviated or offset. Penn Square Bank Penn Square Bank is an illustration of improper asset valuation. In an effort to grow Penn Square bank into a merchant bank and have it become a major financial backer to Oklahoma’s oil men, Bill Jennings hired Bill Patterson to lead his new energy lending division (Caskey, 1985). The energy lending division was tasked to find borrowers for oil customers. As loans were passed to other financial institutions; Penn Square collected fees for originating...

...Potential Implant Failure Posted on February 23, 2016 by admin in Uncategorized How do you tell that your dental implant is failing? “It is failing if it is loose” is the answer most likely to be given by many people. However, while a loose implant is likely to fail, that isn’t the only symptom you should watch out for. Other signs that your implant isn’t likely to integrate or heal properly include: Discomfort Discomfort and pain are some of the first signs that something is wrong with your body. Therefore, pain and discomfort around your dental implant should send you to the dentist. The only exception is if your implant is a recent one, and you are experiencing post-surgical pain associated with healing. However, if you are already done with this early pain, and this is a new one, you may be dealing with something a bit more serious, such as peri-implantitis. This is a bacterial attack around the implant, and it is one of the most...

...One study compared fixed and Dynamic FM performance for hearing aid users, while the other made the same comparison with cochlear implant recipients. In the hearing aid study, conducted by Dr. Linda Thibodeau, both adults and children (ages 11 tol5) were used as subjects, and both objective and subjective measures were taken. The objective comparisons were conducted in a large classroom, with the interfering noises - ranging from 54 dB to 80 dB - emanating from four speakers located in the corners of the room. The FM microphone was placed six inches from another loudspeaker located in the center of the room. The goal was to create a situation where someone would talk into an FM microphone while the listener was surrounded by changing levels of ambient noises. For the subjective comparisons, the subjects tried both the fixed and the adaptive systems at home and during activities in a public aquarium. As expected, the objective results show no difference between the two systems at low noise levels. This is because the adaptive feature is not triggered until the background noise level exceeds 57 dB. But as the noise level increased, the speech perception scores increased with the adaptive system only, reaching a maximum difference of about 50 percent at the higher noise levels. Across all noise levels, the average difference between the fixed and the adaptive systems was about 25 percent. Subjectively, too, most or all (depending upon the activity) of the subjects preferred the...

...Even with good oral health practices like regular brushing, flossing and dental visits, tooth loss can occur. The good news is that if you lose a tooth to decay, gum disease or an injury, you can now get an implant which will look just like your natural tooth. Dentist Thad Kawakami-Wong of AAWindward Dental Group offers advice on getting dental implants. Understanding Implants A dental implant is a replacement for a tooth root. When you lose a tooth, the root is often damaged. An implant replaces the root with a synthetic root, usually made of titanium, to which a replacement tooth can be attached. The dentist places the implant into the socket in the jawbone that is left by the root that has been damaged. The jawbone will heal around...

...Mixed hearing loss is a combination of conductive and sensorineural. Central hearing loss is a problem in the central nervous system involving the inability to interpret sound. Functional hearing loss is caused by an emotional or psychological factor in which there is no physical finding of hearing loss (Lewis et al., 2011) Mosby and Elsevier (2009) (Crusse & Kent, 2013). To determine the type of hearing loss, type of hearing device needed and proper fit, there are different doctors with different levels of education a person can see. Choosing a correct hearing specialist is important. An Audiologist can identify and access hearing disorders. They can also select and correctly fit hearing aids. Audiologists can also program cochlear implants and provide counseling services, rehab and instruction on device usage. An Audiologist is required to have a doctorate or masters degree. A Hearing Aid Specialist can access, select, fit and dispense hearing aids. The can also instruct rehabilitation and counsel in use and care of hearing aids. A certification by the National Board of Certification in Hearing Aid Sciences is...

...Services The demand for implant treatment has increased as patients have become better educated, and insurance companies have begun to recognize the treatment as a long term cost effective way to replace missing teeth, and to improve overall gum health. As part of their cost saving structure, most dental insurance companies have begun offering coverage for portions of implant related surgery. “According to new dental reports by iData Research (www.idataresearch.net), the leading global authority in medical device, dental and pharmaceutical market research, the U.S. market for dental implants is expected to regain double-digit growth by 2013, and will help drive the dental prosthetic market to reach over 82 million prosthetic placements by 2016.” (idata research.net, 2012) “Dental implants have earned the reputation of being the best aesthetic option for single-tooth replacement," said Dr. Kamran Zamanian, CEO of iData. "By 2016, over 20% of general practitioners are expected to place dental implants and their adoption of computer-guided-surgery will further the growth of this market." (idata research.net, 2012) In the past the treatment options were limited to extractions with no replacement teeth, dentures, or fixed bridges. All of these options were stop gap measures to maintain oral stability. The cost of progressively treating the loss of a tooth in one or more areas often involved multiple procedures and time, which made it very expensive. With implants replacing a tooth root...

Petit Institute for Bioengineering and Bioscience, Georgia Institute of Technology, Atlanta, GA, USA St. Joseph’s Translational Research Institute, Atlanta, GA, USA 3 University of Texas Health Science Center at San Antonio, San Antonio, TX, USA 2 ABSTRACT The surface properties of materials contribute to host cellular response and play a significant role in determining the overall success or failure of an implanted biomaterial. Rough titanium (Ti) surface microtopography and high surface free energy have been shown to enhance osteoblast maturation in vitro and increase bone formation in vivo. Whereas the surface properties of Ti are known to affect osteoblast response, host bone quality also plays a significant role in determining successful osseointegration. One factor affecting host bone quality is patient age. We examined both in vitro and in vivo whether response to Ti surface features was affected by animal age. Calvarial osteoblasts isolated from 1-, 3-, and 11-month-old rats all displayed a reduction in cell number and increases in alkaline phosphatase–specific activity and osteocalcin in response to increasing Ti surface microtopography...

...Microchip Implants in Humans. A technology I have been interested in has been the microchip implant. This is a transponder encased in silicate encased in silicate glass and implanted in the body. These typically contain a unique ID number that can be lined to the information contained in an external database, such as personal identification, medical history, and medications. This advance in technology can help with GPS tracking on a human. If a child was lost or abducted this chip could be tracked and potentially save the child’s life. Someone suffering from Alzheimer’s could benefit from this. We could keep better track on criminals who disappear once released and maintain updated records on those who should be registered as offenders. People with medical conditions could benefit from the implant as well. This implant could provide health information allowing a paramedic to scan your chip and administer proper medicine. If you were to pass out or have a heart attack and were unresponsive this could save your life. There have been trials of drug-releasing microchips. The results came back successful in women who were given doses of Osteoporosis. The results were published on the website of the journal Science Translational Medicine. A major impact I believe we could benefit from the microchip would be better security. There are some companies that have been using this technology. Rather than trying to remember or keeping from passing codes, this chip allows you access...
