Mechanical Heart valves are designed to mimic natural heart valves as closely as possible. The valve is implanted in the heart of the patient where the damaged heart valve was removed. Artificial heart valves allows for correct blood flow through the heart by opening and closing with each heartbeat (St Jude Medical, n.d.). The Medtronic mechanical heart valve contains two leaflets (Medtronic, 2011). The pressure in the heart causes the leaflets to open and close, allowing blood flow in only…

and Biocompatibility of the Carpentier Edwards Magna Ease Aortic Heart Valve Chelsea Gibbs University of Utah Statement of Purpose: This report will look at the biomaterials used in the Carpentier-Edwards Perimount Magna Ease Aortic Heart Valve (CEPME) (Edwards Lifesciences LLC, Irvine, CA) and some of the biocompatibility issues found with this device. The CEPME bioprosthesis is designed to replace a diseased aortic heart valve that is no longer functioning properly and the tissue cannot be…

Visual Prosthesis: Selling a Dream to Visually Impaired (A literature review of advancements in the field of Visual Prosthesis) Abstract Visual prosthesis is by far the best bet to restore vision in a patient suffering with visual loss. This paper provides a literature review of the various technological advancements made over time and how these advancements have proved noteworthy in fields of visual prosthesis. To develop a basic understanding about the visual prosthesis, the anatomy and…

Mechanical heart valves provide their greatest benefit by replacing a fatigued natural valve with a prosthesis that was specifically engineered for the variety of patients who experience heart valve disease, thus relieving the patient of most associated conditions and improving their quality of life. However, throughout the last half century there have been many cases of structural failure and induced conditions such as thrombosis due to the materials used in these devices. Through the many case…

The Edwards SAPIEN heart valve is a collapsible aortic heart valve that can be introduced into the body via a catheter-based delivery system. The valve is designed to replace a patient’s diseased aortic valve without traditional open-heart surgery and while the heart continues to beat. The valve can be implanted in patients using the fransfemoral technique meaning delivered thorough the femoral artery or trans-apical technique meaning delivered via a small incision between the ribs. Prior to…

Researching for life’s improvements is the goal for every engineer, this explains the countless hours engineers spend inside an office or a laboratory. Although people think of engineers as only creators of lifeless technology, many of biomedical engineers specialized in technology for the living. Meeting between medicine and engineering, biomedical engineers find solutions for medicine and, in some cases, people’s disabilities. These disabilities appear from accidents in the workplace to war…

It is relatively obvious for human to associate technology in terms of automation, machinery, impersonal and such, rather than to communication and conversation, prior to the intervention of communicative technologies. The nineteenth century had witnessed and experienced the rapid evolution of the large quantity of electronic devices for communication, for instance, telephone, radio, television, and internet. Among all, telephone technology emerged as ‘an integral part of’ everyday lives for…

In “No Need to Call”, Sherry Turkle formulates various arguments regarding technology. Technology gives people the opportunity to do what they wish whether they are emails, instant messages, texts, or calls. Emails, instant messages, and texts are similar for the reason that you are allowed to respond whenever you want, whether it is ten minutes later or a day later. Technology has helped people communicate around the world in an easier way. Anyone can simply go onto their mobile phone or laptop…

Nowadays, within the continuing development of technology, many High-Tech things have been invented and created. The High-tech products make people’s life easier and interesting, we couldn’t image the life without those things. Like the Smart phone, you don’t have to write a letter and sent it to the post office, just by type in the words and click the “send” bottom to the person who you want to be sent to the message. There are a lot of good things that we can talk about the smart-phone has…

One’s Marriage, The Eye and Faith When texting someone, emojis are straightforward, with a laughing emoji symbolizing laughter and clocks representing a clock. On a heart rate monitor, a flashing heart would symbolize the human heart beating in real time. In short stories however, symbols are more ambiguous. The symbols need more time to be identified and explained to those who do not see them. The symbols in “The Story of an Hour” by Kate Chopin, “The Tell-Tale Heart” by Edgar Allan Poe and…
