Rotational thrombectomy wire
First Claim
1. A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material, the thrombectomy wire comprising a core having a proximal portion and a distal portion, the distal portion having a smaller diameter than the proximal portion, a cable extending distally of the core and having a first covering material positioned external thereof, a first coil attached to a distal portion of the cable, the first coil having a diameter larger than a diameter of the cable and having a second covering material positioned thereover, the wire being rotatable by a motor, the wire having a sinuous distal portion to create a wave pattern upon rotation to macerate thrombus.

Abstract
A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material having a core having a proximal portion and a distal portion. The distal portion has a smaller diameter than the proximal portion. A cable extends distally of the core. The cable has a first covering material positioned external thereof. A first coil is attached to a distal portion of the cable and has a diameter larger than a diameter of the cable and has a second covering material positioned thereover. The wire is rotatable by a motor.
