Abstract:
Devices described herein include an actuated clot retrieval catheter system. The system includes a catheter having a frame disposed proximate the distal end of the catheter. The frame expands to form a seal with the inner wall of a vessel. In some examples, the frame also captures a clot for removal from the vessel. The frame is manufactured from a shape memory material that can be heat set into a predetermined shape. An electrical connection to an electronic circuit causes a current to run through the frame. The electrical resistance of the shape memory material causes the frame to heat and transition from a martensite to an austenite phase. When the frame is heat set into an expanded configuration, the current causes the frame heat and expand. When the frame is heat set into a closed configuration, the current causes the frame heat and collapse upon a clot.
