Abstract
Catheters for ablation and removal of occlusions from blood vessels are 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. A helical or partially-helical inner surface structure is provided in the catheter, the structure operable to remove or translate dislodged material(s).
Claims20
A catheter assembly comprising:
- a catheter having a tubular wall, the tubular wall comprising a distal end and an orifice for a lumen extending proximally from the distal end, the lumen having an inner surface comprising a helical structure extending along a length thereof;
- and
- a plurality of optical fibers located within the tubular wall and exposed at the distal end of the catheter.
A catheter aspiration system comprising:
- a catheter having a tubular wall, the tubular wall comprising a distal end and an orifice for a lumen extending proximally from the distal end, the lumen having an inner surface comprising a helical structure extending along a length thereof;
- and a plurality of optical fibers located within the tubular wall and exposed at the distal end of the catheter;
- and
- a vacuum pump in fluid communication with the catheter.
