Abstract
Abstract 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.

Dependent Claim
88 words
The apparatus according to claim 1 wherein said first means for subcutaneous implantation comprises a first member, said second means for supercutaneous placement comprises a second member, and said hook and loop fastening means includes a first part adapted to be attached to the skin, and a second part attached to a side of said second member adapted to face the skin, wherein said hook and loop fastening means has an area smaller than an area of the side of said second member adapted to face the skin.
Claim 4
Dependent Claim
36 words
The apparatus according to claim 2 wherein said hook and loop fastening means is a VELCRO ring disposed so that said second member is adapted to be in direct contact with the skin inside the ring.
Claim 5
Dependent Claim
36 words
The apparatus according to claim 2 wherein said hook and loop fastening means comprises a set of small VELCRO patches disposed so that said second member is adapted to be in direct contact with the skin.
Claim 6
Dependent Claim
27 words
The apparatus according to claim 4 wherein said VELCRO patches are arranged in a non-linear fashion so as to enforce a particular orientation on said second member.
Claim 7
Dependent Claim
14 words
The apparatus according to claim 5 wherein said VELCRO patches comprise two parallel strips.
Claim 8
Independent Claim
112 words
A method of attaching an external unit of a transcutaneous transducer to the skin in a position to optimize coupling with an implanted unit, comprising the steps of: securely attaching a first VELCRO surface to a surface of said external unit, said first VELCRO surface having an area smaller than an area of the surface of said external unit; securely attaching a second VELCRO surface, disposed to adhesively mate with said first VELCRO surface, to the skin in a position above an implanted unit providing optimal coupling, said second VELCRO surface having an area smaller than an area of the surface of said external unit; and bringing said VELCRO surfaces into contact.
Claim 9
Independent Claim
112 words
A method of attaching an external unit of a transcutaneous transducer to the skin in a position to optimize coupling with an implanted unit, comprising the steps of: securely attaching a first VELCRO surface to a surface of said external unit, said first VELCRO surface having an area smaller than an area of the surface of said external unit; securely attaching a second VELCRO surface, disposed to adhesively mate with said first VELCRO surface, to the skin in a position above an implanted unit providing optimal coupling, said second VELCRO surface having an area smaller than an area of the surface of said external unit; and bringing said VELCRO surfaces into contact.
Claim 10
Dependent Claim
23 words
The method according to claim 7 wherein said attaching step comprises attaching the second VELCRO surface to the skin with a stoma adhesive.
Claim 11
Dependent Claim

The method according to claim 7 further including forming said VELCRO surfaces to be ring-shaped.
Claim 12
Dependent Claim
49 words
The method according to claim 7 further comprising the step of identifying a position above said implanted unit providing optimal coupling by using an external testing coil to measure the mutual inductance with a coil contained in said implanted unit and determining where externally the mutual inductance is maximum.
Claim 13
Dependent Claim
61 words
The method according to claim 7 wherein said implanted unit is an intracochlear stimulator, and wherein the method further comprises the step of identifying a position above said implanted unit providing optimal coupling by transmitting signals representative of sound from said external unit to said implanted unit in a patient and asking the patient at what location the signal appears strongest.
Claim 14
Dependent Claim
37 words
The method according to claim 8 further comprising the step of identifying a position above said implanted unit providing optimal coupling, said position being identified by detecting the location of target patterns placed on said implanted unit.
