Abstract

Reprogramming of implanted pacemakers is made more reliable and secure by utilizing a pad having an adhesive surface provided on its upper and lower contacting layers. In the illustrated embodiment, the pad is generally circular with a central circular hole. The pad is placed over the implanted pacemaker at a predetermined position utilizing the central aperture hole for alignment of the pad on the site of pacemaker implantation. An auxiliary cardiac device, such as a programming head, is then disposed on the upper adhesive of the circular pad. The shape of the pad inherently induces the medical technician to appropriately register the auxiliary device relative to the pacemaker. The double adhesive layers of the pad provide temporary affixation of the auxiliary device relative to the pacemaker during the reprogramming or other pacemaker manipulation so that inadvertent relative movement of the auxiliary device relative to the programmable pacemaker is avoided.

Claims

1. An apparatus for use in programming an implanted pacemaker comprising:

a double sided adhesive pad for fixing on a first side of said pad to a skin implantation site over said implanted pacemaker and for fixing on a second side to an auxiliary device used in programming said implanted pacemaker;

means for visually registering said pad relative to said implanted pacemaker as said pad is being fixed to said skin implantation site; and

means for visually registering said auxiliary device relative to said pad,

whereby said pacemaker may be reliably programmed without risk of relative movement of said auxiliary device with respect to said pacemaker during programming of said pacemaker.

2. The apparatus of claim 1 wherein said means for registering said pad comprises a central aperture defined completely through said pad to permit visual sighting and alignment of said pad as said pad is disposed onto said implantation site.

3. A method for manipulating an auxiliary device relative to an implanted programmable pacemaker comprising the steps of:

positioning an adhesive pad on the implantation site of said pacemaker at a predetermined position relative to said pacemaker;

adhering said pad to said implantation site at said predetermined position;

positioning said auxiliary device on said pad at a predetermined position relative to said pad; and

adhering said auxiliary device to said pad at said predetermined position on said pad,

whereby said auxiliary device is temporarily affixed relative to a predetermined position of said pacemaker during manipulation of said pacemaker.

4. The method of claim 3 wherein said steps of positioning and adhering said pad to said implantation site are performed simultaneously by providing an adhesive layer on said pad and disposing said adhesive layer in contact with said implantation site.

5. The method of claim 3 wherein said steps of positioning and adhering said auxiliary device are performed simultaneously and comprise the step of disposing said auxiliary device on an adhesive bearing layer of said pad at a predetermined position on said pad.

6. The method of claim 5 wherein said steps of positioning and adhering said pad to said implantation site are performed simultaneously by providing an adhesive layer on said pad and disposing said adhesive layer in contact with said implantation site.

7. The method of claim 3 wherein said step of positioning said pad relative to said implantation site comprises the step of positioning a guiding aperture defined in said pad at said predetermined position relative to said implantation site.

8. The method of claim 3 wherein said step of positioning said auxiliary device relative to said pad comprises the step of registering said auxiliary device to said pad by conforming the configuration of said auxiliary device with a similar shape provided by said pad.

9. The method of claim 8 wherein said step of positioning said pad relative to said implantation site comprises the step of positioning a guiding aperture defined in said pad at said predetermined position relative to said implantation site.

10. A method of registering an auxiliary device to a reprogrammable implanted pacemaker and temporarily maintaining an auxiliary device in position with respect to said pacemaker comprising the steps of:

exposing an adhesive layer on a first surface of a shaped foam pad having an alignment aperture defined therethrough;

viewing said implantation site over said pacemaker by using said alignment aperture to register said pad relative to said implanted pacemaker; and

then simultaneously disposing said adhesive first surface on a predetermined site over said implanted pacemaker, said alignment aperture provided for viewing said implantation site over said pacemaker as said pad is disposed over said implanted pacemaker.

11. The method of claim 10 further comprising the step of exposing an upper adhesive layer of said pad and disposing said auxiliary device on said upper exposed surface of said pad to temporarily affix said auxiliary device to said pad and hence relative to said implanted pacemaker.

12. The method of claim 11 wherein said step of disposing comprises the step of registering said auxiliary device with respect to said pad by aligning said auxiliary device with respect to a predetermined shape of said pad.

13. The method of claim 12 wherein said predetermined shape of said pad simulates the shape of the contacting surface of said auxiliary device when disposed above said implanted pacemaker.

14. The method of claim 12 wherein said pad is generally circular and has a central circular aperture defined therethrough, to simulate a circulate target symbol.
