First Claim
Patent Images
1. A guidewire torquing device, comprising:
- a body having a proximal end, a distal end and a lumen disposed therethrough;
a proximal end cap associated with the proximal end of the body;
a distal end cap associated with the distal end of the body, the distal end cap having a tapered inner surface;
a collet disposed within the lumen of the body, the collet having a proximal end, a distal end, a collet lumen and at least one groove formed partially therebetween, the distal end of the collet having a tapered surface, the tapered surface of the collect being shaped having a taper complementary to that of the inner surface of the cap;
a lever pivotally associated with the body; and
an actuator associated with the lever, the actuator configured to move the collet to engage and disengage a guidewire disposed through the collet lumen thereof, the lever being pivotal towards the body to engage the collet with the guidewire and pivotal away from the body to disengage the collet with the guidewire and secure the guidewire torguing device to the guidewire.

6. A guidewire torquing device, comprising:
-
a body having a distal end cap, a proximal end, and a lumen extending from the distal end cap towards the proximal end, the distal end cap having a tapered inner surface; a collet disposed within the lumen of the body, the collet having a tapered distal end complementary to the tapered inner surface of the body, a proximal end, and at least one groove extending from the distal end toward the proximal end; and an actuator assembly associated with the body, a first portion of the actuator assembly being pivotally movable relative to the body and a second portion of the actuator assembly being slidably movable within the body toward the proximal end and the distal end of the body to selectively engage the collet with a guidewire disposed through the collet lumen. - View Dependent Claims (7, 8, 9, 10)

11. A method of attaching a torquing device to a guidewire, comprising
providing a guidewire torquing device, the guidewire torquing device having a body and a lumen disposed therethrough, the lumen configured to receive a guidewire therein; -
disposing a guidewire through the lumen; and moving a lever associated with the guidewire torquing device from a first position with a portion of the lever being spaced apart from the body to a second position with the portion of the lever being moved toward the body, wherein movement of the lever applies a force to a locking collet disposed within the torquing device, the locking collet moving from a first position to a second position to engage;
the torquing device to the guidewire. - View Dependent Claims (12, 13, 14, 15)

16. A method of selectively positioning a torquing device to a medical device, the method comprising
positioning a torquing device upon a medical device, the torquing device having a body and a lumen therethrough and a locking collet disposed therein, the lumen and the locking collet each configured to receive a portion of the medical device; - and
moving a lever associated with the torquing device from a first lever position with a portion of the lever being spaced apart from the body to a second lever position with the portion of the lever being moved toward the body, movement of the lever causing a force to be applied to the locking collet to move the locking collet from a first collet position allowing the torquing device to move along the medical device to a second collet position whereby the torquing device engages the medical device and the torquing device is prevented from moving along the medical device. - View Dependent Claims (17, 18, 19, 20)
