Abstract
A catheter for electrophysiology applications includes a shaft and an end effector. The shaft extends along a longitudinal axis to a distal end. The end effector is coupled to the distal end of the shaft. The end effector includes at least one loop member including a pair of spines. The end effector further includes a plurality of first electrodes affixed to at least one spine of the at least one loop member. The end effector further includes at least one flex circuit secured to the at least one spine of the at least one loop member. The at least one flex circuit includes a plurality of second electrodes.

A catheter for electrophysiology applications, comprising:
- (a) a shaft extending along a longitudinal axis to a distal end;
- and
- (b) an end effector coupled to the distal end of the shaft, the end effector including:
- (i) at least one loop member including a pair of spines,
- (ii) a plurality of first electrodes affixed to at least one spine of the at least one loop member, and
- (iii) at least one flex circuit secured to the at least one spine of the at least one loop member, the at least one flex circuit including a plurality of second electrodes.
An end effector of a catheter, the end effector comprising:
- (a) at least one loop member including a pair of spines, the spines of each loop member extending parallel to a longitudinal axis;
- (b) a plurality of first electrodes affixed to at least one spine of the at least one loop member, and
- (c) at least one flex circuit secured to the at least one spine of the at least one loop member, the at least one flex circuit including a plurality of second electrodes.
An end effector of a catheter, the end effector comprising:
- (a) at least one loop member including a pair of spines, the spines of each loop member extending parallel to a longitudinal axis, at least one spine of the at least one at least one loop member including a plurality of apertures;
- (b) a plurality of first electrodes affixed to the at least one spine of the at least one loop member, and
- (c) at least one flex circuit woven through the plurality of apertures, the at least one flex circuit including a plurality of second electrodes.
A catheter for electrophysiology applications, comprising:
- (a) a shaft extending along a longitudinal axis to a distal end;
- and
- (b) an end effector coupled to the distal end of the shaft, the end effector including:
- (i) a loop member including a spine,
- (ii) a flex circuit secured to the spine, the flex circuit comprising:
- (1) an elongated substrate with a first substrate side and a second substrate side opposing the first substrate side, and
- (2) a plurality of first substrate electrodes disposed on the first substrate side and a plurality of second substrate electrodes disposed on the second substrate side, each first substrate electrode being laterally offset from each second substrate electrode.
