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.
Claims26
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.
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;
- and
- an atraumatic tip affixed to a distal end of the engagement section,
- wherein the deployable element has a contracted state suitable for insertion into a vessel, and is configured to be selectively actuated using a deployment knob coupled to the handle to deploy to a plurality of predetermined states.
A method for treating a cerebral occlusion, the method comprising:
- providing apparatus comprising a catheter body having proximal and distal ends, a handle affixed to the proximal end, an engagement section affixed to the distal end, the engagement section comprising at least one deployable element provided in a contracted state, and an atraumatic tip affixed to a distal end of the engagement section;
- advancing the deployable element through an occlusion in the contracted state;
- deploying the deployable element distal of the occlusion;
- and
- retracting the deployable element to engage the occlusion.
