Method for optimally positioning and securing the external unit of a transcutaneous transducer of the skin of a living body

摘要

A transcutaneous coupling device having an implanted unit and an external unit uses VELCRO for attaching the external unit to the skin in a proper location for optimal electromagnetic coupling between the units. The VELCRO has two surfaces, which adhere to one another, one surface being affixed to the external unit, and the other surface being adhesively attached to the skin. In one embodiment, the VELCRO is a patch coextensive with the surface area of the side of the external unit. In another embodiment, where the thickness of the VELCRO interferes with the coupling, the VELCRO takes the form of a ring or set of smaller patches permitting projecting portions of the side of the external unit to directly contact the skin for better coupling.
