Abstract

Devices, systems and methods for retrieving clot material from a vasculature lumen are provided. In one embodiment, a medical device includes a handle, a catheter, a tether member and a clot retrieval element. The catheter extends from the handle and the clot retrieval element is configured to be positioned within a distal portion of the catheter with the tether member extending between the handle and the clot retrieval element. The clot retrieval element is configured to be deployed from within the catheter so that the catheter moves proximally relative to and separate from the clot retrieval element while maintaining attachment to the clot retrieval element via the tether member. Further, the clot retrieval element is configured to be pulled by the tether member to abut against a distal side of a clot with proximal movement of the tether member to pull the clot from the vasculature lumen.
