Abstract

Devices described herein include an actuated clot retrieval catheter system. The system includes a catheter having a metallic region positioned at the distal tip of the catheter. The metallic region includes at least two abutting metals in a bimetallic coil configuration. The bimetallic coil expands to form a seal with the inner wall of a vessel. In some examples, the bimetallic coil also captures a clot for removal from the vessel. The bimetallic coil is manufactured from metal-based materials having different thermal expansion coefficients. Conductive wires extend along a longitudinal axis of the catheter from an electrical current controller to at least a portion of the metallic region. Electrical current to the metallic region causes the bimetallic coil to transition from a tight configuration to an expanded configuration and remove the clot.
