Abstract

An implantable medical device system is configured to generate signals and deliver the signals to a heart of a patient. The implantable medical device system includes electronic circuitry configured to deliver cardiac pacing, couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry, a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of polymeric material filled around the electronic circuitry and couplings and forming the implantable medical lead receptacle. The implantable medical device may include a first cavity filled with a first material and a second cavity filled with a second material, and the first material is different than the second material.

Claims (8)

1. An implantable medical device comprising:

electronic circuitry including a battery pack and a hybrid board configured to generate and deliver cardiac pacing;

couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry; and

a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of at least one polymeric material filled around the electronic circuitry and couplings and also forming the implantable medical lead receptacle, wherein the at least one polymeric material includes a first material and a second material, wherein the implantable medical device includes a first set of openings containing the couplings for the implantable medical lead and filled with the first material and a second set of openings containing the electronic circuitry and filled with the second material, and wherein the first material is different than the second material.

2. The implantable medical device of claim 1 , wherein the first material is medical adhesive.

3. The implantable medical device of claim 1 , wherein the second material is epoxy.

4. The implantable medical device of claim 1 , wherein the first material is medical adhesive, and the second material is epoxy.

5. The implantable medical device of claim 1 , wherein the couplings include a setscrew block and a setscrew.
