Abstract:
A treatment of a medical difficulty associated with the formation or presence of a blood clot in a blood vessel, commonly known as “thrombectomy.” Said treatment may be achieved by introducing and positioning through a single lumen a device capable of macerating, irrigating and aspirating as well as supporting structures proximal to the distal end of said device. Said device is introduced via a blood vessel, and deployed at a treatment site. The macerator is then operated to dislocate thrombus, clot, or other occlusive materials at the target site, the irrigating element is then operated to continue to dislocate thrombus, clot, or other occlusive materials at the target site, and the aspirating element is used to collect and remove the disruptive materials from the target site.

Claim (Index 1):
A medical device for ameliorating thrombi, comprising three concentric sheaths including embedded lumens adapted for insertion into a blood vessel, comprising:\n (a) an inner hypotube,\n including a proximal tip, and a distal tip including at least one perforation, and at least one macerating element capable of both expanding and collapsing;\n wherein said distal tip is adapted to irrigate a blockage, and said proximal tip communicates via a dedicated lumen, terminating at an irrigation source outside said patient's body, and \n wherein said at least one perforation is disposed distally to at least one connection point and proximally to an attachment point and areas therebetween, said at least one perforation communicates by a separate lumen with said proximal tip to allow injection of fluid therethrough from outside said body; \n \n (b) an intermediate hypotube,\n including a distal aperture and a proximal end;\n wherein said at least one macerating element is affixed to said inner hypotube at said at least one connection point, and attached to said intermediate hypotube at said attachment point located on a rim of said distal aperture; \n \n (c) an outer sheath,\n including a distal opening adapted to aspirate debris, and a proximal opening communicating via a dedicated lumen, terminating at an aspiration control device outside a patient's body;\n wherein said outer sheath is disposed within said blood vessel, having said distal opening adapted to aspirate debris and said proximal opening communicating with said aspiration control device; \n wherein said intermediate hypotube slides along the exterior surface of said inner hypotube, \n wherein said inner hypotube and said intermediate hypotube are adapted to rotate together 360\u00b0, and \n wherein said inner hypotube and said intermediate hypotube incorporate an interlocking element adapted to prevent rotation of said inner hypotube relative to said intermediate hypotube, as well as to facilitate the longitudinal movement of said inner hypotube.
