Abstract
A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel comprising a flexible sheath, and a wire positioned within the flexible sheath wherein the wire and flexible sheath are relatively movable. The wire is substantially sinuous in configuration and assumes a substantially sinuous shape when in the deployed position and assumes a straighter position in the retracted position. The wire is operatively connected to a motor for rotation of the wire to enable peaks of the sinuous wire to contact a wall of the lumen to break up the thrombus or other obstructive material.
Claims23
A thrombectomy apparatus for breaking up thrombus or other obstructive material in a lumen of a vascular graft or vessel, the apparatus comprising a flexible sheath and a wire positioned within the flexible sheath, the wire and flexible sheath being relatively movable so the wire has a first configuration and a second deployed configuration, the wire being sinuous in configuration and assuming its sinuous configuration when in the deployed configuration and having a straighter configuration in the first configuration, the wire being operatively connected to a motor for rotation of the wire to enable peaks of the sinuous wire to contact a wall of the lumen to break up the thrombus or other obstructive material.
A thrombectomy apparatus comprising a flexible sheath and a rotatable wire positioned within the flexible sheath, the wire and flexible sheath being relatively slidable so the wire is movable between a substantially straightened position and a deployed position where it assumes a curved configuration, in the curved configuration the wire having a first arcuate region extending in a first direction and a second arcuate region spaced longitudinally from the first arcuate region and extending in a second direction, the first and second arcuate regions configured to break up thrombotic material as the wire spins.
A thrombectomy apparatus comprising a flexible sheath and a wire rotatably positioned within the flexible sheath, the wire composed of at least one wire forming an inner core and at least one wire around the inner core to form an outer layer, the wire having a first arcuate region extending in a first direction, a second arcuate region extending in a second direction, and a substantially linear region, the first and second arcuate regions breaking up thrombotic material in a vascular structure as the wire spins.
A thrombectomy apparatus comprising a flexible tube, a wire having a non-linear configuration and positioned within the flexible tube and rotatable with respect to the flexible tube, the wire having a non-linear configuration, first and second balloons inflatable to expand radially with respect to the flexible tube, and a motor for rotating the wire to break up thrombotic material as the wire rotates about its axis.
A thrombectomy apparatus for performing a thrombectomy procedure to break up thrombus from a graft functioning as a shunt between an artery and a vein, the apparatus comprising a flexible catheter having a declotting mechanism to break up thrombotic material or other obstructive material, a first angioplasty balloon inflatable to expand radially with respect to the flexible catheter to perform an angioplasty procedure, and a second balloon inflatable to a configuration capable of pulling vascular material into the graft.
A method for breaking up the thrombotic material from a lumen of a vascular graft or vessel comprising;
- inserting a sheath;
- exposing a rotatable wire with respect to the sheath, the wire having a sinuous configuration;
- and
- rotating the wire so peaks of the sinuous wire directly contact the graft wall as the wire spins.
A method for performing a thrombectomy procedure to break up thrombotic material in a vascular graft which forms a shunt between an artery and a vein, the method comprising:
- inserting an introducer sheath;
- providing a thrombectomy device having at least one inflatable balloon;
- inserting the thrombectomy device through the introducer sheath and into a vascular lumen;
- inflating the at least one balloon to expand the balloon radially from the thrombectomy device;
- deflating the balloon;
- and
- actuating the thrombectomy device to break up thrombotic material from the graft.
