Mechanical thrombectomy device for use in cerebral vessels
First Claim
1. Apparatus suitable for treating a cerebral occlusion, the apparatus comprising:
- a catheter body having proximal and distal ends and a handle affixed to the proximal end;
an engagement section affixed to the distal end of the catheter body and comprising at least one deployable element, the deployable element having a contracted state suitable for insertion into a vessel and a deployed state; and
an atraumatic tip affixed to a distal end of the engagement section, wherein the deployable element is configured to self-expand to a predetermined hook shape extending radially outward from the engagement section and in a proximal direction in the deployed state.

Abstract
Apparatus and methods for treating cerebral occlusions are provided, comprising a thrombectomy device having at least one deployable element. The deployable element is advanced through the occlusion in a contracted state, then self-deploys distal of the occlusion or, alternatively, may be deployed to a wide range of configurations using a physician-actuated deployment knob. The thrombectomy device then may be retracted to cause the deployable element to snare the occlusion, and/or rotated circumferentially to cause the fibrin strands of the occlusion to be wrapped around the deployable element.
