Vascular treatment device
First Claim
Patent Images
1. A vascular treatment device comprising:
- a handle having;
a motor;
a trigger mounted on the handle and transitionable between a first state that does not electrically couple the motor to a power source and a second state that does couple the motor to the power source; and
a male coupling rotably driven by the motor; and
a cartridge engageable with the handle and having;
a female coupling so sized and shaped as to be engageable by, and once engaged by, to be rotated by the male coupling;
a wire having a proximal end fixed to the female coupling, a main shaft extending therefrom and terminating at a distal end; and
a sheath fixed to and extending from the cartridge, the sheath defining a lumen through which the wire runs;
wherein the sheath, when the female coupling is not engaged by the male coupling, covers the distal end of the wire, andwherein as the male coupling and the female coupling fully engage each other and the cartridge is engaged with the handle, the male coupling displaces female coupling detents to allow the female coupling to slide within the cartridge, thereby causing the sheath, when the female coupling is engaged by the male coupling, to slide back relative to the wire and uncover the distal end of the wire.

Abstract
A vascular treatment device may include (1) a handle having a motor, a trigger, and a male coupling, and (2) a cartridge, engageable to the handle, having a female coupling, a wire, and a sheath fixed to the cartridge. When the female coupling is not engaged to the male coupling, the sheath may cover the distal end of the wire, allowing safe advancement of the device into the patient'"'"'s vasculature, and when the female coupling is engaged by the male coupling, the distal end of the wire may be exposed from the sheath and used.
