First Claim
Patent Images
1. A catheter aspiration system comprising:
- a catheter having a tubular wall, the tubular wall comprising;
a distal end;
an orifice for an inner lumen extending proximally from the distal end of the catheter; and
an opening in the tubular wall, wherein the opening is disposed in the exterior proximal of the distal end of the catheter;
a plurality of optical fibers located within the tubular wall and exposed at the distal end of the catheter, wherein the plurality of optical fibers comprise corresponding distal ends, wherein the distal ends of the plurality of optical fibers are disposed distally of the opening in the tubular wall;
a vacuum pump in fluid communication with the inner lumen and operable to transmit material proximally through the inner lumen; and
an adjustable gate being movable to selectively cover at least a portion of the opening.

Abstract
A system for ablation and removal of occlusions from blood vessels is provided. Laser cutting systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Aspiration systems are further provided, the aspiration systems operable to remove ablated, cut, or dislodged material through a primary orifice at the distal end of the catheter and/or through an auxiliary orifice, which may be on the side of the catheter.
