Abstract
A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material having a core having a proximal region and a distal region and being rotatable by a motor. The distal region has a smaller diameter than the proximal region. A cable is coupled to the distal region of the core and extends distally thereof. A torque tube is positioned over the cable and a coil is positioned over a distal portion of the cable. A distal portion of the cable has a non-linear configuration. A first covering material is positioned over the coil.

A rotational thrombectomy wire for breaking up vascular thrombus or other obstructive material in a cerebral artery of a patient, the thrombectomy wire comprising a proximal portion, a distal portion, a core dimensioned for insertion through the cerebral artery of the patient and a cable extending distally of the core, the cable having a proximal region stiffer than a distal region, and a cover positioned over the cable, the thrombectomy wire further having a coil at a distal tip thereof, the distal portion of the thrombectomy wire having a non-linear configuration and insertable through a sheath wherein the distal portion assumes a more linear configuration for delivery into the cerebral artery, and the thrombectomy wire having a proximal portion for operatively coupling to a motor by a clinician, the thrombectomy wire rotatable by the motor to macerate thrombus within the cerebral artery.
