As with all systems, there is always a certain risk of leakage, blockage or other mechanical failure that cannot be excluded. However the A.M.I. Anal Band System minimizes this risk because there are no mechanical components that could be subject to wear and tear.
The A.M.I. Soft Anal Band System is made up of just two different materials. One is a pure, medical-grade silicone (rubber) suitable for long-term implants, and the other is pure, medical-grade titanium. This device does not contain any silicone gel or silicone oil. Solid silicone elastomers and titanium have been used for many years as materials for medical implants.
It is not possible to predict how long an implanted prosthesis will work for a particular patient. As with any other biomedical prosthesis, this device is also subject to a certain amount of wear, which may affect its life-span. Such a system should never be assumed to last a lifetime. A malfunction in the system may lead to additional surgery being necessary to replace the implant. Patients should discuss any noticeable changes in the operation of their system with their doctor.
Doctors refer to the slow change in position of any part of the system as migration. In this case, migration would generally involve a component moving up towards the surface of the skin. Patients should contact their doctor immediately if any part of the system is visible through the skin, but also in the event that the activator and/or valve cannot be located.
