Antenna for an external power source for an implantable medical device, system and method
First Claim
1. An antenna for a completely external power source for an implantable medical device situated completely under a continuous cutaneous boundary of a patient, said implantable medical device having therapeutic componentry and a secondary coil operatively coupled to said therapeutic componentry, comprising:
- a housing having a first surface adapted to be placed closest to said secondary coil of said implantable medical device; and
a primary coil operatively coupled to said external power source and inductively energizing said secondary coil transcutaneously across said continuous cutaneous boundary, said primary coil being wound forming generally concentric loops having an axis;
said housing having a central protrusion centrally located with respect to said axis of said primary coil extending from said first surface, a peripheral protrusion extending from said first surface at least partially surrounding an outer periphery of said primary coil, and an area between said central protrusion and said peripheral protrusion co-planar with said first surface.

Abstract
System, method and antenna for an external power source for an implantable medical device having therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. A housing has a first surface adapted to be placed closest to the secondary coil of the implantable medical device. A primary coil is operatively coupled to the external power and is capable of inductively energizing the secondary coil, the primary coil being wound forming generally concentric loops having an axis. The housing has a protrusion extending from the first surface.

18. A system for transcutaneous energy transfer across a continuous cutaneous boundary, comprising:
-
a completely implantable medical device, comprising; a therapeutic componentry; and a secondary coil operatively coupled to said therapeutic componentry; and a completely external power source, comprising; an antenna comprising; a housing having a first surface adapted to be placed closest to said secondary coil of said implantable medical device; and a primary coil operatively coupled to said external power source and inductively energizing said secondary coil transcutaneously across said continuous cutaneous boundary when externally placed in proximity of said secondary coil, said primary coil being wound forming generally concentric loops having an axis; said housing having a central protrusion centrally located with respect to said axis of said primary coil extending from said first surface, a peripheral protrusion extending from said first surface at least partially surrounding an outer periphery of said primary coil, and an area between said central protrusion and said peripheral protrusion co-planar with said first surface.

19. A method of transcutaneous energy transfer across a continuous cutaneous boundary to a medical device completely implanted in a patient having a secondary charging coil using an external power source having a housing containing a primary coil, said housing having a first surface nearest to said secondary coil, said housing having a protrusion extending from said first surface, comprising the steps of:
-
positioning said primary coil completely externally of said patient with respect to said secondary coil; pressing said protrusion and said first surface against skin of said patient; transferring energy transcutaneously across said continuous cutaneous boundary from said primary coil to said secondary coil. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
