Abstract
A device includes a catheter section comprising a flexible joint region disposed between a distal end and a proximal end. The device includes a laser fiber disposed within the catheter section. The laser fiber emits laser light at a fiber distal end. The device includes a wire comprising a distal end coupled to the catheter section. The wire is configured to move the distal end of the catheter section from a first position to a second position about the flexible joint region.
Claims21
A device comprising:
- a catheter section comprising a distal end and a proximal end;
- a flexible joint region located at the distal end and including a lumen formed by tubing that runs through the catheter section, wherein a distal end of the flexible joint region includes a portion of the tubing extending as an extension past a distal end of the flexible region;
- a laser fiber disposed within the catheter section, wherein the laser fiber emits laser light at a fiber distal end;
- a wire comprising a distal end coupled to the catheter section, wherein the wire is a push-pull wire configured to be pushed distally and pulled proximally along a longitudinal axis of the wire such that translation of the wire distally or proximally effects flexion of the distal end of the catheter section about the flexible joint region, wherein a distal portion of the wire has a smaller diameter than a proximal portion of the wire.

A method comprising:
- forming a catheter section to include a distal end and a proximal end;
- configuring the catheter section to include a flexible joint region at the distal end, and forming a lumen in the flexible joint region with tubing that runs through the catheter section, wherein a distal end of the flexible joint region includes a portion of the tubing extending as an extension past a distal end of the flexible region;
- housing a laser fiber within the catheter section, wherein the laser fiber emits laser light at a fiber distal end;
- housing a wire in the catheter section and coupling a distal end of the wire to the catheter section, wherein a distal portion of the wire has a smaller diameter than a proximal portion of the wire, wherein the wire is a push-pull wire configured to be pushed distally and pulled proximally along a longitudinal axis of the wire such that translation of the wire distally or proximally effects flexion of the distal end of the catheter section about the flexible joint region, wherein a distal portion of the wire has a smaller diameter than a proximal portion of the wire.
