Atherectomy device handle with guide wire clamp override device
First Claim
1. An atherectomy device comprising:
- a handle housing;
a rotatable prime mover movable longitudinally with respect to the handle housing;
a rotatable drive shaft having a proximal end connected to the prime mover for rotation and longitudinal movement therewith, and a distal end portion having a tissue removal implement usable to remove tissue from a bodily passageway;
a guide wire disposed within the drive shaft and having a proximal portion extending proximally from the proximal end of the drive shaft;
a guide wire clamp disposed within the handle housing for releasably clamping the proximal portion of the guide wire, the guide wire clamp being selectively movable from a guide wire-clamped position to a guide wire-released position;
the handle housing being shaped and sized with respect to the guide wire clamp to permit manual movement of the guide wire clamp from its guide wire-clamped position to its guide wire-released position; and
an override clamp removably securable to the handle housing to move the guide wire clamp to the guide wire-released position and to hold the guide wire clamp in such position.

Abstract
An atherectomy device having a handle housing, a rotatable prime mover movable longitudinally with respect to the handle housing, a rotatable drive shaft having a proximal end connected to the prime mover for rotation and longitudinal movement therewith, and a distal end portion having a tissue removal implement usable to remove tissue from a bodily passageway. A guide wire clamp is disposed within the handle housing for releasably clamping the proximal portion of a guide wire. An override clamp is removably securable to the handle housing for moving the guide wire clamp to a guide wire-released position and for holding the guide wire clamp in such released position. The override clamp may also include a mechanical linkage to the prime mover so that the override clamp locks the prime mover in a particular longitudinal position with respect to the handle housing.

13. An atherectomy device comprising:
-
a handle housing; a rotatable prime mover disposed within the handle housing and being movable longitudinally with respect to the handle housing; a rotatable drive shaft having a proximal end connected to the prime mover for rotation and longitudinal movement therewith, and a distal end portion having a tissue removal implement usable to remove tissue from a bodily passageway; a guide wire disposed within the drive shaft and having a proximal portion extending proximally from the proximal end of the drive shaft; a guide wire clamp disposed within the handle housing and comprised of a pair of opposed clamping blocks and a clamp biasing mechanism for moving the clamping blocks from a guide wire-released position to a guide wire-clamped position; the handle housing including one or more clamp override openings aligned with the clamp to permit manual override of the clamp biasing mechanism; and an override clamp removably securable to the handle housing in alignment with the one or more clamp override openings and causing the clamp biasing mechanism to release the clamping blocks from the guide wire-clamped position. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. An atherectomy device comprising:
-
a handle housing; a rotatable drive shaft having a proximal end and a distal end portion with a tissue removal implement usable to remove tissue from a bodily passageway; a guide wire disposed within the drive shaft and having a proximal portion extending proximally from the proximal end of the drive shaft; a guide wire clamp carried by the handle housing for releasably clamping the proximal portion of the guide wire, the guide wire clamp being selectively movable from a guide wire-clamped position to a guide wire-released position; and an override clamp removably securable with respect to the handle housing to move the guide wire clamp to the guide wire-released position and to hold the guide wire clamp in such position.
