Mapping grid with high density electrode array

A catheter is described with an end effector having densely arrayed electrodes on three loops which are arrayed in various planar configurations when the end effector is unconstrained. The end effector has first, second and third loop members, each loop member includes two spines and a connector tha...

Zusammenfassung:A catheter is described with an end effector having densely arrayed electrodes on three loops which are arrayed in various planar configurations when the end effector is unconstrained. The end effector has first, second and third loop members, each loop member includes two spines and a connector that connects the two spines to define a loop extending away from a tubular member of the catheter such that the first, second and third loop members are configured so that each connector of each of the first, second and third loop members is in contact with only one connector of the adjacent loop member.
