The present invention provides apparatus and methods for treating a vascular condition by restoring patency to a vessel while reducing the likelihood that emboli become dislodged into the bloodstream. In a first embodiment, the apparatus comprises a graft having proximal and distal regions, a first support member attached to the distal region of the graft, and a second support member attached to the proximal region of the graft. The first and second support members may comprise first and second stents, respectively. The first stent is deployed distal to a vascular condition, and the second stent is deployed proximal to a vascular condition, such that the graft spans the length of the vascular condition to entrap emboli during treatment of the vascular condition. In an alternative embodiment, the graft is adapted to be everted to form a pocket adapted to entrap emboli dislodged during treatment of the vascular condition.

Apparatus and methods for in situ embolic protection

A vascular closure device includes a frame to which there is fitted a plurality of anchor elements, spaced radially around the frame. The closure device includes a radial compression feature, which may be a memorized shape of the frame or non-sprung condition of the frame, having a small radius. The closure device is deployed in a vessel such that the anchor elements are embedded into the vessel wall. The radial compression feature causes the frame to compress radially, as a result of which the anchor elements will pull the vessel wall inwardly, thereby closing the vessel.

Vascular closure device

An embolic coil delivery system includes a flexible elongate body having a distal segment. An embolic coil is loaded on the flexible elongate body at the distal segment and contacts an outer surface of the flexible elongate body. The embolic coil delivery system also includes a delivery catheter sized to advance over the flexible elongate body during an embolic coil delivery procedure, wherein a distal segment of the delivery catheter contacts the embolic coil during the embolic coil delivery procedure.

Embolic coil delivery system

A delivery system for an occlusion balloon includes a delivery catheter and a balloon releasably detached thereto. The balloon can include a base portion that is threaded onto the end of the delivery catheter. The balloon can include a one-way valve or septum in the base portion, through which a filling needle is inserted into a cavity of the balloon. The balloon can be filled with a fluid to expand the balloon and fix the balloon within the patient's body. The balloon can be filled with a hardening material to assist in fixing the balloon in place and occluding the blood vessel. The balloon can include anchoring structure on its outer surface to assist in the fixing the location of the balloon. The delivery device and needle can be detached and withdrawn from the balloon, allowing the septum to close and seal the balloon, leaving the balloon fixed within the body vessel.
