Abstract
A thrombectomy device includes a coring member configured to disintegrate a thrombus in a vessel into fragments from a proximal side of the thrombus and a catch member configured to be anchored at a distal side of the thrombus to provide embolic protection. The coring member and the catch member are operable independently of each other. Methods of removing a thrombus from a vessel employ a rotating coring device to disintegrate the thrombus into fragments.
Claims60
A thrombectomy device, comprising:
- a coring member configured to disintegrate a thrombus in a vessel into fragments;
- and
- a catch member configured to be anchored at a distal side of the thrombus to provide embolic protection,
- wherein the coring member and the catch member are operable independently of each other.
A thrombectomy device, comprising:
- an elongate shaft having a proximal end and a distal end;
- an expandable structure coupled to the distal end of the elongate shaft;
- and
- a catheter configured to deliver the expandable structure in a collapsed state to a location in a vessel containing a thrombus, wherein
- the expandable structure in an expanded state is rotatable with the elongate shaft to disintegrate the thrombus into fragments.
A method of removing a thrombus from a vessel in a patient, comprising:
- a) introducing a catheter to a vessel containing a thrombus;
- b) advancing the catheter through the thrombus to position a distal end of the catheter at a distal side of the thrombus;
- c) delivering a catch member in a collapsed state through the catheter to the distal side of the thrombus;
- d) expanding the catch member to an expanded state;
- e) retracting the catheter to position the distal end of the catheter at a proximal side of the thrombus;
- f) delivering a coring member in a collapsed state through the catheter to the proximal side of the thrombus;
- g) advancing the coring member into the thrombus to disintegrate the thrombus into fragments;
- and
- h) applying a negative pressure to the catheter to aspirate the fragments out of the vessel.

- c) delivering a coring device in a collapsed state through the catheter to the distal side of the thrombus;
- d) retracting the catheter to position the distal end of the catheter at a proximal side of the thrombus;
- e) applying a negative pressure to a lumen of the catheter to aspirate the thrombus;
- and
- f) retracting the coring device while rotating through the thrombus, whereby the thrombus is disintegrated into fragments, and the fragments are aspirated by the catheter out of the vessel.
