Abstract
Systems and methods for performing aspiration thrombectomy. The aspiration catheter assembly can include a support catheter and an aspiration catheter extending through the support catheter. The catheter assembly can include a distal valve apparatus that can control a level of vacuum at a distal end of the catheter system. Irrigation can flow between the support catheter and the aspiration catheter to flush the catheter assembly.
Claims14
An aspiration catheter assembly for removing a clot, the aspiration catheter assembly comprising:
- a support catheter comprising an elongate tubular body and a valve for controlling a level of vacuum at a distal end of the aspiration catheter assembly;
- an aspiration catheter disposed within the support catheter and capable of moving relative to the support catheter, the aspiration catheter comprising an aspiration lumen for receiving at least a portion of the clot;
- and
- a stopper configured to prevent the aspiration catheter from moving beyond a preset distance from the distal end of the support catheter.
An aspiration catheter assembly for removing a clot, the aspiration catheter assembly comprising:
- a support catheter configured to be in fluid connection with an irrigation source;
- an aspiration catheter configured to be in fluid connection with a vacuum source, the aspiration catheter disposed within the support catheter and capable of moving relative to the support catheter, the aspiration catheter comprising an aspiration lumen for receiving at least a portion of the clot;
- and
- a valve for controlling a level of vacuum at a distal end of the aspiration catheter assembly and preventing irrigation flow out of the distal end of the aspiration catheter assembly;
- wherein the aspiration catheter is configured to move between an extended position when a distal end of the aspiration catheter is advanced distal of the valve and a retracted position when the distal end of the aspiration catheter is retracted proximal of the valve;
- wherein in the retracted position, fluid from the irrigation source is allowed to flow through a space between the support catheter and the aspiration catheter, into the distal end of the aspiration catheter, and proximally out of the aspiration catheter;
- and
- wherein in both the retracted position and in the extended position, fluid from the irrigation source does not flow out of the distal end of the support catheter.
