Claims
- 1. An electrode adapted for implantation on or about a heart and for connection to a system for monitoring or stimulating cardiac activity, the electrode comprising:
- a flexible polymeric substrate formed as a silicone rubber tube having an exposed surface layer;
- a region of the exposed surface layer impregnated with a metal to form an electrically conductive surface;
- an electrical conductor for electrical connection to the system; and
- a conductive adhesive joining the conducting surface to the electrical conductor.
- 2. The electrode of claim 1 further comprising a strain relief encapsulating the electrical conductor.
- 3. The electrode of claim 1 wherein the metal is platinum.
- 4. The electrode of claim 1 further comprising a strain relief surrounding the electrical conductor and conductive adhesive, and an outer tubing coaxially disposed around the silicone rubber tube having a distal end terminating within the strain relief, and wherein the conductor is insulatively disposed between the silicone rubber tube and the outer tubing.
- 5. The electrode of claim 1 wherein the electrode further comprises a termination ring conductively connected to the electrical conductor, and the conductive adhesive joins the termination ring and the electrical conducting surface.
