Abstract
A torque device for attaching to and selectively gripping or securing and releasing a guidewire to permit rotational and longitudinal manipulation of the guidewire to steer and control the guidewire. In one embodiment the torque device comprises a nose portion, a neck portion, and a base portion with varying outer diameters for improved rotational control.
Claims20
A medical torque device comprising:
- a nose portion having a first outer circumference;
- a neck portion having a second outer circumference, the second outer circumference being smaller than the first outer circumference;
- and
- a base portion having a third outer circumference which is greater than the second outer circumference;
- wherein a distal end of the neck portion is connected to a proximal end of the nose portion and the base portion with an inner lumen which extends through the nose portion, neck portion, and base portion and through which a guidewire may pass.
2 more elements
A medical torque device comprising:
- a first component comprising:
- a nose portion having a first outer circumference;
- a neck portion having a second outer circumference, the second outer circumference being smaller than the first outer circumference;
- a base bottom portion having a guidewire-locking groove where a guidewire positioned within the base bottom portion is exposed;
- and
- an inner lumen which extends through the nose portion, neck portion and base bottom portion which houses the guidewire;
- a base top portion including a guidewire-locking ridge which is capable of applying a pinching force on the guidewire positioned within the guidewire-locking groove when the first component and the base bottom position are urged together;
- and
- an urging means applies an urging force to urge the base top portion towards the base bottom portion of the first component.
6 more elements
A medical torque device comprising:
- a first component comprising:
- a nose portion having a cylindrical shape having a first outer circumference;
- a neck portion having a cylindrical shape having an outer circumference with a cross-section with a polygonal shape having at least three sides and at least three vertices where the sides meet;
- a base bottom portion having a guidewire-locking groove where a guidewire positioned within the base bottom portion is exposed;
- and
- an inner lumen which extends through the nose portion, neck portion and base bottom portion which houses the guidewire;
- a base top portion including a guidewire-locking ridge which is capable of applying a pinching force on the guidewire positioned within the guidewire-locking groove when the first component and the base bottom position are urged together;
- and
- an urging means applies an urging force to urge the base top portion towards the base bottom portion of the first component,
- wherein the base top portion and the base bottom portion together form an assembled base portion which has a conical outer circumference wherein a distal end of an assembled base top portion and first portion at a region where the base bottom portion connects to the neck portion has a smaller circumference than a proximal end of the assembled base portion.
