Abstract
A multi-electrode catheter has a longitudinally extending body with a number of longitudinally extending lumens formed therein and a number of electrode assemblies. Each assembly has an electrode located at an external surface of a caudal section of the body and an electrical conductive surface extending longitudinally within an associated lumen of the number of lumens connected to a cephalad section of the body. The conductive electrical surface forms at least a portion of an internal wall of the associated lumen and is in electrical connection with a different one of the electrodes forming the electrode assemblies.
Claims5
A multi-electrode catheter comprising:
- a longitudinally extending body adapted for insertion in a subject, said body having a caudal section and a cephalad section and a plurality of lumens formed therein proceeding between said caudal section and said cephalad section, each of said lumens having an internal wall, said caudal section having an external surface and said body having a body portion disposed between said internal wall and said external surface;
- a plurality of electrode assemblies respectively including a plurality of electrodes located at said external surface of the caudal section of the body;
- at least some of said lumens having an electrically conductive surface formed on the internal wall thereof;
- and
- a plurality of electrical connections proceeding through said body portion and respectively electrically connecting the electrically conductive surface of at least some of said lumens to different ones of said electrodes.
