US 2024/0197392 A1 · MULTI-ELECTRODE BASKET END EFFECTOR OF A CATHETER

Abstract

Examples presented herein illustrate various end effector designs with multiple spines that can expand from a collapsed configuration as the end effector traverses vasculature to an expanded configuration when the end effector is at a treatment site. In some examples, the end effector includes three frame loops which each include a pair of spines. At least one of the three frame-loops can have a bend at a distal end of the end effector so that the spines of the frame loop are not directly opposite each other with respect to the longitudinal axis. In some examples, the end effector includes an inner and an outer frame, each having multiple spines and configured such that one or both of the frames can rotate from an aligned configuration to an unaligned configuration.

Dependent claims

An end effector of a catheter, the end effector comprising:

a plurality of spines configured to expand away from a longitudinal axis of the end effector to form a basket shape;
a first frame loop comprising a first pair of spines of the plurality of spines such that spines of the first pair of spines are disposed across from each other with respect to the longitudinal axis;
a second frame loop, distinct from the first frame loop, comprising a second pair of spines of the plurality of spines such that spines of the second pair of spines are disposed on a first side of the first frame loop;
a third frame loop, distinct from the first frame loop and the second frame loop, comprising a third pair of spines of the plurality of spines such that spines of the third pair of spines are disposed on a second side of the first frame loop, the second side being opposite the first side;
and
one or more electrodes coupled to the plurality of spines.

a second frame loop, distinct from the first frame loop, comprising a second pair of spines of the plurality of spines and a second angled portion approximate the distal end of the end effector such that the second angle portion overlaps the first angled portion, an inner spine of the first pair of spines is positioned between spines of the second pair of spines, and an inner spine of the second pair of spines is positioned between spines the first pair of spines;
a third frame loop, distinct from the first frame loop and the second frame loop, comprising a third pair of spines of the plurality of spines and a third angled portion approximate the distal end of the end effector such that spines of the third pair of spines are each disposed between outer spines of the first pair of spines and the second pair of spines;
and
one or more electrodes coupled to the plurality of spines.
