Abstract
A rotatable thrombectomy wire for breaking up thrombus or other obstructive material comprising an inner core composed of a flexible material and an outer wire surrounding at least a portion of the inner core. The outer wire has a sinuous shaped portion at a distal region. The inner core limits the compressibility of the outer wire. The outer wire is operatively connectable at a proximal end to a motor for rotating the wire to macerate thrombus.
Claims17
A motor driven rotational thrombectomy wire for breaking up thrombus or other obstructive material comprising an inner core, first and second outer wires wound over the inner core, a polymeric material over a first portion of the outer wires to provide a less abrasive surface during wire rotation, a metal tip positioned over a second portion of the outer wires, and a flexible blunt tip positioned over the metal tip and extending distally therefrom and extending distally of the polymeric material, the metal tip extending distally of a distalmost end of the first and second outer wires and extending proximally of a proximalmost end of the flexible blunt tip, the thrombectomy wire operatively connectable to a motor for rotation by the motor.
