Abstract

A transcutaneous transmission pouch provides a pocket on a flexible substrate adherable to a user'"'"'s skin. The flexible substrate is adhered to the user'"'"'s skin closest to the location where an implantable device is implanted. An antenna coil, including associated electrical circuitry needed to transmit power and data signals to the implantable device from an external power/control source, are removably inserted into the pocket of the flexible substrate in order to hold the antenna coil in an aligned position with the implantable device during a power or data signal transfer.

Claims

1. A method for transmitting signals through the skin of a user to a receiving coil of an implantable unit, comprising the steps of:

(a) providing a flexible transcutaneous pouch having a pocket formed therein wherein electronic circuitry coupled to a power source for transmitting signals to the implantable unit may be removably carried, the transcutaneous pouch having means for adhesively securing the transcutaneous pouch to a surface of the user'"'"'s skin; and

(b) detachably securing the transcutaneous pouch to the user'"'"'s skin at a position that allows signals to be coupled from the electronic circuitry to the implantable unit; and

(c) inserting the electronic circuitry into the pocket of the transcutaneous pouch; and

(d) coupling the power source to the electronic circuitry carried in the pocket of the transcutaneous pouch, wherein the electronic circuitry is enabled and transmits signals to the implanted unit.

2. The method of claim 1 wherein step (c) comprises inserting the electronic circuitry and power source into the pocket of the transcutaneous pouch.

3. A transcutaneous transmission pouch assembly, comprising a transcutaneous transmission system, wherein the transcutaneous transmission system includes an implantable portion and an external portion, and wherein the external portion includes a first antenna coil and electrical circuitry means for transmitting at least one of power and data signals through the first antenna coil for coupling to the implantable portion;

and a transcutaneous transmission pouch comprising;

a flexible substrate adherable to a users skin; and

a pocket formed in the flexible substrate;

wherein the first antenna coil and at least a first portion of the electrical circuitry means, when placed in the pocket of the flexible substrate, are sufficiently aligned with the implantable portion of the transcutaneous transmission system to allow at least one of the power and data signals to be efficiently coupled into the implantable portion.

4. The transcutaneous transmission pouch assembly as set forth in claim 3 wherein the flexible substrate includes an adhesive base and a removable backing covering the adhesive base.

5. The transcutaneous transmission pouch assembly as set forth in claim 4 wherein the external portion includes a housing, and wherein the first antenna coil and the first portion of the electrical circuitry means associated with the non-implantable portion are carried within the housing, and further wherein the housing fits within the pocket of the flexible substrate.

6. The transcutaneous transmission pouch assembly as set forth in claim 4 wherein the external portion includes a housing, and wherein the first antenna coil and all of the electrical circuitry means associated with the external portion are carried within the housing, and further wherein the housing fits within the pocket of the flexible substrate.
