Implantable medical device electrode assembly
First Claim
1. An implantable medical device comprising:
- an electrode that forms a first snap-fit attachment area;
an insulator that forms a through-hole, a second snap-fit attachment area and a third snap-fit attachment area, wherein the second snap-fit attachment area mates with the first snap-fit attachment area of the electrode; and
a body including an elongated conductive housing and a feedthrough wire extending therefrom, wherein the body forms a fourth snap-fit attachment area on one end that mates with the third snap-fit attachment area of the insulator such that the feedthrough wire extends through the through-hole of the insulator,wherein the housing encloses at least one of a battery, a sensor, or an electronic circuit, andwherein the insulator functions to electrically isolate the electrode from the housing of the body.

Abstract
An implantable medical device (IMD) includes an electrode that forms a first snap-fit attachment area and an insulator that forms a through-hole, a second snap-fit attachment area and a third snap-fit attachment area. The second snap-fit attachment area mates with the first snap-fit attachment area of the electrode. The IMD further includes a body including an elongated conductive housing and a feedthrough wire extending therefrom. The body forms a fourth snap-fit attachment area on one end that mates with the third snap-fit attachment area of the insulator such that the feedthrough wire extends through the through-hole of the insulator. The housing encloses at least one of a battery, a sensor, and an electronic circuit. The insulator functions to electrically isolate the electrode from the housing of the body.

15. A method of assembling an implantable medical device, wherein the implantable medical device includes:
-
an electrode that forms a first snap-fit attachment area, an insulator that forms a through-hole, a second snap-fit attachment area and a third snap-fit attachment area, wherein the second snap-fit attachment area is configured to mate with the first snap-fit attachment area of the electrode, and a body including an elongated conductive housing and a feedthrough wire extending therefrom, wherein the body forms a fourth snap-fit attachment area on one end that is configure to mate with the third snap-fit attachment area of the insulator, wherein the housing encloses at least one of a battery, a sensor, and an electronic circuit, wherein the method comprises; securing the insulator to the body by mating the third snap-fit attachment area of the insulator with the fourth snap-fit attachment area of the body to form an assembly including the insulator and the body with the feedthrough wire extending through the through-hole of the insulator; and securing the electrode to the assembly including the insulator and the body by mating the first snap-fit attachment area of the electrode with the second snap-fit attachment area of the insulator, wherein the insulator functions to electrically isolate the electrode from the housing of the body. - View Dependent Claims (16, 17, 18, 19)
