Abstract
A cardiac electrode termination pair system that is particularly compatible with Magnetic Resonance Imaging (MRI) procedures. The electrodes include tip and ring electrodes made of a body-compatible ceramic on which is applied via electroplating, sputtered or the like an ultra-thin conductive coating of platinum or titanium or other suitable metal which is compatible with conducting electrical impulses into cardiac tissue. The ring electrode may be adapted for connection to a photonic catheter carrying light signals or a non-photonic catheter carrying electrical signals. The ring (or the tip) may house pulse-delivering components and/or sensing components.
Claims21
A cardiac electrode termination pair system, comprising:
- a tip, said tip including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- a ring, said ring including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- and
- an insulative material disposed between said tip and said ring.
In a pacemaker, a cardiac electrode termination pair system, comprising:
- a tip, said tip including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- a ring, said ring including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- and
- an insulative material disposed between said tip and said ring.
A medical system comprising:
- a control unit adapted to generate cardiac stimulation signals and/or to receive a sensing signal representing a cardiac function;
- a catheter having a proximal end in communication with said control unit for carrying said stimulation signals and/or said sensing signal, said catheter further having a distal end;
- and
- an electrode termination pair mounted to said catheter distal end, said electrode termination pair comprising:
- a tip, said tip including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- a ring, said ring including a bio-compatible ceramic base structure coated with a layer of electrically conductive material;
- an insulative material disposed between said tip and said ring;
- and
- means in said ring or said tip for delivering said stimulation signals to an implanted heart and/or for sensing said cardiac function and generating said sensing signal.
