Rotational thrombectomy wire

Abstract

An assembly insertable into a lumen of a patient including a motor housing having a motor contained therein, a motor shaft extending from the motor, a first coupler positioned at the motor shaft having a first magnet positioned therein adjacent a distal end, a rotational wire, and a second coupler positioned at a proximal portion of the thrombectomy wire. The second coupler has a second magnet positioned therein adjacent a proximal end. The second coupler is engageable with the first coupler to operably connect the rotational wire to the motor shaft, the first and second magnets providing an attractive force between the first and second couplers to maintain a connection of the first and second couplers so rotation of the first coupler rotates the second coupler.

1 . An assembly insertable into a lumen of a patient for a neurovascular thrombectomy procedure, the assembly comprising:
 a motor housing having a motor contained therein;   a motor shaft extending from the motor;   a first coupler positioned at the motor shaft, the first coupler having a first magnet positioned therein adjacent a distal end;   a rotational neuro-thrombectomy wire; and   a second coupler positioned at a proximal portion of the rotational wire, the second coupler having a second magnet positioned therein adjacent a proximal end, the second coupler engageable with the first coupler to operably connect the rotational wire to the motor shaft, the first and second magnets providing an attractive force between the first and second couplers to maintain a connection of the first and second couplers so rotation of the first coupler rotates the second coupler, the positionable in a cerebral artery for high speed rotation to perform the neurovascular thrombectomy procedure.
