Abstract
Clot retrieval devices are described that may include a cutting element and a clot capture basket connected to a distal region of an elongated device body and located proximally or distally of each other. The cutting element may help remove or cut a clot from a vessel wall and/or may help cut or breakup a clot into smaller components/pieces. The capture basket may capture at least some of the clot (e.g., whole or smaller pieces) and withdraw the clot/pieces from the vessel. The device body may include one component or several different components that may move relative to each other to assist in the cutting and capture process.
