Download file to see previous pages The manufacturing of stents is usually conducted in a careful method that a features the use of highly complex and advanced processes in order to meet the requirements.
Some of the common methods that are used in the manufacture of stents include the identification of the optimal materials to be used in the manufacture. The choice of material is of supreme value because it determines the effectiveness of the product. A poorly chosen optimal raw material would lead to cases of maladjustment with the results that the stent would be ill suited to perform the kind of task for which it was designed. Laser cutting techniques feature prominently in the manufacture of stents (Shrivastava 25). The use of laser is necessary for the purposes of ensuring precision. The laser cutting processes usually involves the application of complex geometries that are determined by the minute measurements applied within the process.
Cardiovascular, peripheral, or neurovascular blood vessels are some of the vessels that often receive the support of stents for purposes of support and scaffolding. Stents also apply in providing solutions to some natural passages gastrointestinal and urinary tracts, which are often prone to diseases and conditions that affect the processes of natural flow within them (Shrivastava 28). Depending on the tasks for which they are created, stents may differ in make, size, and orientation. Stainless CoCr and Nitinol or a combination of the two is some of the materials that are often used in the manufacture of stents.
The choice of material used in the manufacture of stents is usually determined by the nature and place of usage. Generally, coronary and peripheral stents are made of stainless while neurovascular, carotid, and biliary stents rely more on Nitinol material for their manufacture (Shrivastava 43). The major differences in these stents are defined in ...Download file to see next pagesRead More

...?The Abortion Dilemma Abortion is not a new issue; it has been practiced by many cultures since the beginning of time. The issue is emotionally charged from both camps. It is less emotional in the case of abortion to save the mother's life as opposed to elective abortions for the sake of privacy and reproductive choices; however, there are still proponents who take the hard line approach of letting nature take its course. Feminists are cautiously watching to be sure that women's rights are protected. They maintain that no one should be forced to reproduce, regardless of the reason. Great Britain has the most liberal laws in Europe, allowing abortion on demand up until 24 weeks, while South Africa takes the lead in Africa; yet more...

Biomedical Ethics

...). Therefore, to some extent, the physician may compel a patient to take a certain medication not only because it is the right and objective medical step but also because he feels, based on his values and preferences, it is the right thing. For the latter, he is imposing his personal feelings, not professional mandate, to the patient. In these cases, a physician may be ethically driven to compel a patient to take medication because he feels it is the right thing to do. However, it is essential to note that a physician demonstrates respect for human dignity, a biomedical ethical consideration, when he acknowledges the freedom and right of the patient to make choices based on their own beliefs and values (Kluge 7). Perhaps...

Biomedical Ethics

...Philosophy and the Dignity of Human Life Introduction Human life has always been held as the most important thing in theworld history. Although different professions engage in different kind of activities, all of them are always perceived as methods in which human life can be improved. Ranging from medicine, engineering, poetry, sports and even education, the aim is always the same. However, different philosophers would tend to argue that not every practice leads to an improved human life. Using abortion and sterilization as examples, doctors might argue that they are necessary to save the life of the mother (in case of abortion) and come up with only the healthy and upright thinking (in case of sterilization).

...Biomedical Issues Introduction Understanding issues in Biomedicine needs one to understand what the law entails as well as ethics. This should further demand knowledge of legal considerations when ethical concepts are applied in Biomedicine. An in-depth awareness of limitations encountered by healthcare practitioners with regards to applied main codes of conduct during work is very important. Two concepts explored in Biomedicine are reproductive technologies and life maintenance technologies. Medical practitioners have applied four main theories in ethics to validate decisions adopted during their work processes. They evaluate consequences of their decisions to find out which ones are more valuable to the majority. They...
