CLOT RETRIEVAL METHOD AND DEVICE
First Claim
1. A medical device configured to retrieve clot material from a vasculature lumen, comprising:
- a handle having a catheter extending therefrom;
at least one clot retrieval element configured to be positioned within a distal portion of a lumen defined through the catheter, the at least one clot retrieval element operably attached to the handle with a tether member extending through the lumen of the catheter;
wherein the at least one clot retrieval element is configured to be deployed from within the catheter from a contracted state to an expanded state such that, when in the expanded state, the at least one clot retrieval element conforms to the geometry of the vasculature lumen and applies pressure to the vasculature lumen.

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.

15. A method of retrieving a clot from a vasculature lumen, the method comprising:
-
extending a catheter within a vasculature lumen through a clot; positioning a distal portion of the catheter distally of the clot; deploying at least one clot retrieval element from the distal portion of the catheter while maintaining attachment to the at least one clot retrieval element via a tethering member extending through the catheter; conforming the at least one clot retrieval element to a geometry of the vasculature lumen and applying pressure to a wall of the vasculature lumen with the at least one clot retrieval element; displacing the distal portion of the catheter proximally with respect to the clot; abutting the at least one clot retrieval element against a distal side of the clot; and pulling the clot proximally through the vasculature lumen with the clot retrieval element abutted against a distal side of the clot. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
