Abstract

An improved method for securing an external device of a implantable system, in cooperation with an implantable device of the implantable system, uses a medical-pressure-sensitive adhesive pad to attach the external device to skin. Both power and control signals may be transmitted transcutaneously from the external device to the implantable device. Efficient transmission of these signals requires that the external device be securely held in cooperation with the implantable device. The medical-pressure-sensitive adhesive pad acts as an interposing adhesive between the external device and the skin. One side of the pad provides adhesion to the back of the external device. The opposite side of the pad provides adhesion to the skin/hair. The pad includes a tab for easy removal of the pad from the external device. The adhesives have aggressive adhesion to the pad, so that upon the removal of the pad from the skin, and then the external device, all of the adhesive remains on the pad. Adhesives are available with several degrees of adherence to the skin, thus allowing the selection of the adhesive to suit the requirements of the user and to minimize trauma upon removal.

Claims

1. An adhesive attachment system for a external device of an implantable system, the adhesive attachment system comprising:

a pad with a first surface and a second surface;

a first adhesive residing on the first surface of the pad; and

a second adhesive residing on the second surface of the pad;

wherein the pad it removably attachable to the external device by the first adhesive, and the pad is removably attachable to skin of a user by the second adhesive.

2. The adhesive attachment system of claim 1 wherein the implantable system includes an implantable device, and wherein the pad is adapted to hold the external device adjacent to the implantable device.

3. The adhesive attachment system of claim 1 wherein the first adhesive and the second adhesive have aggressive adhesion to the pad, wherein the first adhesive remains on the pad when the pad is removed from the external device, and wherein the second adhesive remains on the pad when the pad is removed from the skin.

4. The adhesive attachment system of claim 1 wherein the first adhesive has a more aggressive adhesion to the external device than the second adhesive has to the skin, wherein the pad remains attached to the external device when the external device is pulled away from the skin.

5. The adhesive attachment system of claim 1 further comprising a pad tab, wherein pad tab may be pulled to remove the pad from the external device.

6. The adhesive attachment system of claim 1 further comprising a first release liner and a second release liner, wherein the first release liner removably resides on the first adhesive and the second release liner removably resides on the second adhesive.

7. The adhesive attachment system of claim 6 wherein the first release liner includes a first liner tab, and the second release liner includes a second liner tab, and wherein the first release liner is removed from the first adhesive by pulling on the first line tab, and the second release liner is removed from the second adhesive by pulling on the second line tab.

8. The adhesive attachment system of claim 1 wherein the second adhesive comprises a plurality of second adhesives with different adhesion strengths, wherein one of the plurality of second adhesives may be selected by the user to provide the level of adhesion strength suitable for the level of activity anticipated by the user.

9. The adhesive attachment system of claim 8 wherein the plurality of second adhesives comprises adhesives of three different adhesive strengths.

10. The adhesive attachment system of claim 8 wherein the first adhesive comprises a plurality of first adhesives with different adhesion strengths, and wherein one of the plurality of first adhesives may be selected so that when the external device is pulled away from the skin, the pad will remain attached to the external device.

11. The adhesive attachment system of claim 1 wherein the pad is thin.

12. The adhesive attachment system of claim 11 wherein the pad is about 0.025 inches thick.

13. The adhesive attachment system of claim 1 wherein the adhesive attachment system is adapted to act as the sole means used to attach the external device to the skin.

14. The adhesive attachment system of claim 1 wherein the adhesive attachment system is used in cooperation with a magnet means for attaching the external device to the skin.

15. The adhesive attachment system of claim 1 wherein the pad is substantially flat and substantially round, and wherein the pad is about 1 inch in diameter.

16. The adhesive attachment system of claim 1 wherein the pad is 1.060 inches in diameter.

17. The adhesive attachment system of claim 1 wherein the implantable system is an Implantable Cochlear Stimulation (ICS) system.

19. The method of claim 18 wherein the adhesive attachment system further includes a first release liner and a second release liner, wherein the first release liner removably resides over the first adhesive and the second release liner removably resides over the second adhesive, and wherein the method further includes:

removing the first release liner before pressing the first surface against the external device; and

removing the second release liner before pressing the second surface against the skin.

20. The method of claim 19 wherein the first release liner includes a first liner tab, and wherein the second release liner includes a second liner tab, wherein:

removing the first release liner comprises pulling on the first liner tab to remove the first release liner; and

removing the second release liner comprises pulling on the second liner tab to remove the second release liner.

21. The method of claim 18 wherein the method further includes pulling on the external device to remove the external device and pad from the skin.

22. The method of claim 18 wherein the pad includes a pad tab, and wherein the method further includes pulling the pad tab to remove the pad from the external device.

24. The system of claim 23 wherein the implantable system is a Spinal Cord Stimulation (SCS) system.

25. The system of claim 23 wherein the implantable system is a Deep Brain Stimulation (DBS) system.

26. The system of claim 23 wherein the cooperation of the external device with the implantable device includes providing power to the implantable device.

27. The system of claim 23 wherein the cooperation of the external device with the implantable device includes providing control signals to the implantable device.

18. A method for removably attaching an external device of an implantable system to skin, wherein the external device is in cooperation with an implantable device of the implantable system, comprising:

providing an adhesive attachment system, wherein the adhesive attachment system comprises a pad with a first surface and a second surface, wherein a first adhesive resides on the first surface and a second adhesive resides on the second surface;

pressing the first surface against the external device to removably attach the pad to the external device; and

pressing the second surface against the skin to removably attach the external device to the skin.

23. An adhesive attachment system for a external device of an implantable system, the adhesive attachment system comprising:

a pad with a first surface and a second surface;

a first adhesive residing on the first surface; and

a second adhesive residing on the second surface;

wherein the pad it removably attachable to the external device by the first adhesive, and the pad is removably attachable to skin of a user by the second adhesive; and

wherein the adhesive attachment system attaches the external device to the skin to provide for the cooperation of the external device with an implantable device.
