Abstract
Exemplary embodiments of the present disclosure include systems and methods for treatment of occlusions, including coronary artery chronic total occlusions.
Claims68
A system comprising:
- a catheter control system, wherein the catheter control system comprises:
- an imaging system;
- a laser;
- a vacuum source;
- and
- an inert gas source;
- a catheter coupled to the catheter control system, wherein the catheter comprises:
- an imaging fiber coupled to the imaging system;
- a laser fiber coupled to the laser;
- a vacuum lumen coupled to the vacuum source;
- and
- an inert gas lumen coupled to the inert gas source.
9 more elements
A method of treating a chronic total occlusion in a blood vessel, the method comprising:
- deploying a guide wire to a location of the chronic total occlusion;
- deploying a catheter over the guide wire, wherein:
- the catheter comprises a proximal end, a distal end, a plurality of lumens, and a laser fiber;
- the catheter is deployed over the guide wire via a first lumen in the plurality of lumens;
- and
- the distal end of the catheter is positioned at the location of the chronic total occlusion;
- retracting the guide wire from the first lumen in the catheter;
- inserting an imaging fiber into an open lumen of the catheter;
- visually inspecting the location of the chronic total occlusion via the imaging fiber ahead of a focus of the laser fiber;
- cutting material from the chronic total occlusion via the laser fiber;
- retracting the imaging fiber from the first lumen of the catheter;
- inserting the guide wire into the first lumen of the catheter and through the chronic total occlusion;
- and
- retracting the catheter from the location of the chronic total occlusion while the guide wire remains in position extending through the chronic total occlusion.
11 more elements
A catheter configured to penetrate a chronic total occlusion, wherein the catheter comprises:
- a proximal end;
- a distal end;
- an imaging fiber configured to transmit imaging data from the distal end of the catheter to the proximal end of the catheter;
- a laser fiber configured to transmit laser energy from the proximal end of the catheter to the distal end of the catheter;
- a vacuum lumen configured to transmit a vacuum from the proximal end of the catheter to the distal end of the catheter;
- and
- an inert gas lumen configured to transmit an inert gas from the proximal end of the catheter to the distal end of the catheter.
