Abstract
A power source for an implantable medical device, such as a spinal cord stimulator, has a controlled contoured anterior surface. Preferably, the contoured anterior surface includes a layer of a biocompatible material, such as a polymer. Also preferably, the layer provides a contour generally conforming to the profile of a human buttock. Optionally, a cosmetic implant of generally substantially the same size and shape as the power source is implanted in the opposite buttock as the power source so as to create balance.
Claims20
A housing for a power source for supplying power to a medical device, wherein the housing is to be implanted in a contoured buttock of a human or animal subject, comprising:
- an anterior portion of the housing with a contour generally conforming to the contour of the buttock, wherein the contoured anterior portion is substantially rigid;
- a posterior portion of the housing;
- and
- at least one edge between the anterior and posterior portions of the housing, wherein the contoured anterior portion of the housing, the posterior portion of the housing, and the at least one edge form a generally enclosed structure.
An improvement for a power source for spinal cord stimulation, wherein the power source includes a casing with an anterior portion, the power source being implantable into a contoured buttock, the improvement comprising:
- a contoured anterior portion of the casing which generally conforms to the contoured buttock, wherein the contoured anterior portion of the casing is substantially rigid.
An attachment for a power source for a medical device, the power source implantable into a contoured buttock of a human or animal subject and including a casing, the casing having an anterior surface, the attachment comprising:
- a layer of a biocompatible and inert material that attaches to the casing, the layer defining an anterior surface having a smoothly-curved, generally convex contour, the layer anterior-surface contour generally conforming to the contour of the buttock, wherein the layer anterior surface is substantially rigid.
