Abstract
A device that is useful for removing obstructions from vessels. Various embodiments and methods of use are contemplated for the effective removal of obstructions. The disclosed devices utilize a thrombogenic material to promote the formation of fibrin bonds, thus enhancing adhesion. It is further contemplated that the disclosed devices may be used in all vasculature including the cerebral vasculature and the neurovasculature.
Claims14
A system for removing an obstruction from a vessel, comprising:
- an elongate tubular member having a proximal end and a distal end;
- and
- an elongate element having a proximal end, a distal end, and a midsection at least a portion of which is positionable within the elongate tubular member, wherein the distal end of the elongate element includes a capture device operatively connected to the elongate element, wherein the capture device is coated with a thrombogenic material and can assume an expanded condition and a contracted condition.
A method for removing an obstruction from a vessel, utilizing a system including a member having a proximal end and a distal end including a capture device coated with a thrombogenic material and being capable of assuming an expanded condition and a contracted condition, comprising the steps of:
- advancing the system to a treatment site;
- inserting the distal end of the member into the obstruction and allowing the capture device coated with a thrombogenic material to assume an expanded condition, wherein the distal end promotes adhesion to the obstruction utilizing blood-borne constituents, thereby facilitating removal of the obstruction;
- and
- removing the obstruction from a vessel.
