Abstract
Described herein are systems, devices, and methods for aspiration and mechanical thrombectomy. In some embodiments, a thrombectomy device for removing a thrombus from a vessel can include a handle assembly, a vacuum source, an aspiration catheter with an expandable distal portion, and a flexible shaft configured to rotate within the aspiration catheter.
Claims20
A thrombectomy device for removing a thrombus from a vessel,
- the thrombectomy device comprising:
- a handle assembly;
- a vacuum source configured to generate vacuum pressure;
- a catheter coupled to the handle assembly, the catheter including:
- a tubular body defining a lumen;
- and
- an expandable distal portion configured to transition from a collapsed configuration having a first diameter that is substantially similar to a diameter of the tubular body to an expanded configuration having a funnel-like shape that progressively increases to a second diameter that is greater than the diameter of the tubular body,
- wherein the expandable distal portion includes a metallic frame that defines a plurality of rows of open cells and an atraumatic wave-shaped ring having a plurality of troughs disposed at a distal end of the expandable distal portion, and every other open cell of a distalmost row of open cells is connected to a respective trough of the atraumatic wave-shaped ring;
- a flexible shaft;
- a rotational drive assembly configured to rotate the flexible shaft axially and orbitally such that a distal end of the flexible shaft is disposed within about 1 cm from an end of the expandable distal portion and a diameter of an orbital path of the rotating distal end of the flexible shaft is greater than the diameter of the tubular body;
- and
- an actuator disposed on the handle assembly, the actuator configured to be actuated to cause the vacuum source to generate the vacuum pressure within the lumen of the tubular body and to cause the rotational drive assembly to rotate the flexible shaft.
