Abstract
An elongate medical device may comprise an elongate tubular body, an electrode, and a trace. The elongate tubular body may comprise a distal end portion and a proximal end portion, the body defining a longitudinal axis. The electrode may comprise electrically-conductive ink extending circumferentially about a portion of the distal end portion. The trace may comprise electrically-conductive ink, electrically coupled with the electrode, extending proximally from the electrode.
Claims19
An elongate medical device comprising:
- an elongate tubular body defining a longitudinal axis;
- a first electrode that extends circumferentially about a portion of said elongate tubular body, said first electrode defining a circumferential gap;
- a second electrode that extends around the entire circumference of said elongate tubular body;
- a first trace comprising electrically-conductive ink, electrically coupled with said first electrode, extending longitudinally from said first electrode along a surface of said elongate tubular body;
- and
- a second trace comprising electrically-conductive ink, electrically coupled with said second electrode and electrically isolated from said first electrode, extending longitudinally through said circumferential gap of said first electrode;
- wherein at least one of said first electrode and said second electrode comprises a plurality of ribs.
