hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??
Hello, i found this information online, hope it will be helpfull... ?Artificial valves can be used to replace damaged valves in the body that are no longer functioning to keep blood flowing in one direction only. ?Most artificial valves have a fabric ring surrounding them, which allows a surgeon to sew the device into place during implantation. ?Where appropriate, artificial valves are constructed from collagen-rich materials, such as pericardial tissues which have been obtained from pigs or cows and treated (to denature any animal proteins), to minimise the risk of rejection by the human body. Other materials used are cobalt-chromium alloys, low-temperature carbon and titanium alloy with pyrolytic carbon discs or balls.
The cochlea is the auditory portion of the inner ear. A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. An artificial heart valve is a device implanted in the heart of a patient with heart valvular disease. When one of the four heart valves malfunctions, the medical choice may be to replace the natural valve with an artificial valve. This requires open-heart surgery.
Cochlear implants aren't valves, they're implanted behind the ears, they improve hearing in people who are hard of hearing. An artificial valve replaces a heart valve, which controls how much blood flows in and out of the heart.
