Abstract:
1. A device for unblocking an occluded vessel at a remote site having an occlusion therein, the device comprising: a first elongated member for passing through a lumen to the occluded vessel, the first member extending from a proximal end to a distal end and terminating in a distal leading portion adjacent the distal end thereof, and having an elongated bore extending longitudinally therethrough from the proximal end to the distal end and through the distal leading portion, the portion of the bore extending through the distal leading portion being internally threaded, an anchoring means located on the first member for anchoring the first member with the distal leading portion thereof adjacent the occlusion, and a second elongated member extending from a proximal end to a distal end and terminating in a distal leading portion, the distal leading portion of the second member terminating in a distal tip for urging through the occlusion for unblocking the occluded vessel, the distal leading portion of the second member being urgeable through the bore extending through the first member from the proximal end of the first member to the distal end and through the distal leading portion of the first member, and the distal leading portion of the second member being externally threaded, the external threads on the distal leading portion of the second member being engageable with the internal threads of the bore extending through the distal leading portion of the first member, so that rotation of the second member within the bore of the first member urges the distal leading portion of the second member off the anchored first member to in turn urge the distal tip of the second member into engagement with the occlusion when the first member is anchored by the anchoring means with the distal leading portion of the first member adjacent the occlusion.
