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.
Claims15
A rotational thrombectomy wire comprising:
- an inner core composed of a flexible material,
- an at least one outer wire wound over at least a portion of the inner core forming a coil;
- an exterior surface of the coil extending proximally of a distalmost end of the coil;
- the coil having a sinuous shaped portion;
- the inner core having a sinuous shaped portion within the sinuous shaped portion of the coil;
- a polymeric material positioned over the exterior surface of a first portion of the coil to block interstices of the at least one outer wire,
- a portion of a separate distal tip component positioned over the exterior surface of a second portion of the coil;
- a flexible polymeric tip positioned over the distal tip component and extending distally therefrom;
- the distal tip component extending distally of the distalmost end of the coil;
- the distal tip component extending proximally of a proximalmost end of the flexible polymeric tip;
- and
- the thrombectomy wire is operatively connectable to a motor for rotation by the motor.
