Abstract
A system for sensing multiple local electric voltages from endocardial surface of a heart, includes: an elongate tubular member having a lumen, a proximal end and a distal end; a plurality of flexible splines; an anchor for securably affixing the proximal portions of the splines, where the anchor is securably affixed within the lumen of the elongate tubular member at the distal end of the elongate tubular member; and a metallic tip for securably affixing the distal portions of the splines.
Claims20
A basket catheter, comprising:
- a catheter shaft having a proximal end, a distal end, and defining a longitudinal axis therebetween;
- a basket electrode assembly extending distally from the distal end of the catheter shaft, the basket electrode assembly comprising:
- a plurality of splines, each of the plurality of splines comprising a distal portion, a medial portion, and a proximal portion;
- and
- a distal tip coupled to the distal portions of each of the plurality of splines, the distal tip comprising:
- a first structure comprising a plurality of spline alignment features spaced apart such that each one of the respective distal portions of each of the plurality of splines is disposed between a pair of the plurality of spline alignment features;
- and
- a second structure, wherein the distal portions of each of the plurality of splines are secured relative to the second structure by the first structure,
- wherein the distal portions of each of the plurality of splines are coupled to the distal tip in a predetermined angular relationship via the plurality of the spline alignment features.
A basket catheter, comprising:
- a catheter shaft having a proximal end, a distal end, and defining a longitudinal axis therebetween;
- a basket electrode assembly extending distally from the distal end of the catheter shaft, the basket electrode assembly comprising:
- a plurality of splines, each of the plurality of splines comprising a distal portion, a medial portion, and a proximal portion;
- and
- a distal tip having a plurality of detents disposed along a sidewall thereof, wherein the distal portions of each of the plurality of splines is secured within a respective detent of the plurality of detents of the distal tip,
- wherein the distal portions of each of the plurality of splines are secured within the distal tip in a predetermined angular relationship via the plurality of detents.
A basket catheter, comprising:
- a catheter shaft having a proximal end, a distal end, and defining a longitudinal axis therebetween;
- a basket electrode assembly extending distally from the distal end of the catheter shaft, the basket electrode assembly comprising:
- a plurality of splines, each of the plurality of splines comprising a distal portion, a medial portion, and a proximal portion;
- and
- a distal tip coupled to the distal portions of each of the plurality of splines, the distal tip comprising:
- a first structure comprising an interior space for receiving distal portions of each of the plurality of splines such that the distal portions of each of the plurality of splines are coupled to the distal tip in a predetermined angular relationship;
- and
- a second structure, wherein the distal portions of each of the plurality of splines are secured relative to the second structure by the first structure.
