Abstract
One preferred embodiment includes a guidewire manipulation device for manipulating a guidewire during a procedure. Preferably, the guidewire manipulation device includes a powered motor that drives a tandem roller assembly. The guidewire is passed through a hole positioned lengthwise through the device where the roller assembly engages the guidewire's outer surface. The interface of the manipulation device includes a power button that directs the internal roller assembly to roll the guidewire in a desired rotational direction. Additional interface controls are also preferable to provide a different roll patterns, depending upon surgeon preference and guidewire placement efficiency.
Claims18
A guidewire manipulation device comprising:
- a casing sized to at least partially fit within a user's hand, the casing having a distal end and a proximal end;
- a passage extending along a length of said casing and sized for passage of a guidewire therethrough;
- a hub slidably connected to the distal end of the casing, the hub having an interior cavity, the interior cavity comprising at least one internal angled passage;
- a member, comprising either a wedge or a wedge tube, displaced within the interior cavity of the hub;
- a rotation assembly fixed within said casing and positioned to engage said guidewire positioned within said passage;
- a motor disposed within said casing and operatively coupled to said rotation assembly so as to drive rotation of said rotation assembly;
- a power supply connected to said motor;
- and
- an interface in communication with said motor for selectively actuating movement of said motor, wherein the hub is configured to be axially slidable distally in relation to the proximal end of the casing, such that the at least one internal angled passage biases the member against the guidewire, thereby locking the guidewire from movement relative to the hub.
A guidewire manipulation device comprising:
- a casing, having a distal end and a proximal end, sized to at least partially fit within a user's hand;
- a passage extending along a length of said casing and sized for passage of a guidewire therethrough;
- a hub slidably connected to the distal end of the casing, the hub having an interior cavity, the interior cavity comprising at least one internal angled passage;
- a member, comprising either a wedge or wedge tube, displaced within the interior cavity of the hub;
- a rotation assembly fixed within said casing and positioned to engage said guidewire positioned within said passage;
- and
- a manually actuated rotation mechanism at least partially disposed within said casing for driving said rotation assembly based on hand movement of a user, wherein the hub is configured to be axially slidable distally in relation to the proximal end of the casing, such that the at least one internal angled passage biases the member against the guidewire, thereby locking the guidewire from movement relative to the hub.
A method of manipulating a guidewire comprising:
- introducing a guidewire into a patient;
- sliding a manipulation device over said guidewire;
- engaging a rotation assembly with said guidewire;
- advancing said guidewire into said patient;
- and
- actuating said manipulation device to rotate said guidewire in a first direction, wherein said engaging a rotation assembly with said guidewire includes wedging a member, located within a slidable hub having at least one angled internal passage, in the distal region of said manipulation device, against the guidewire thereby locking the guidewire against movement relative to the hub.
