Abstract
A system for traversing an arterial occlusion in an artery includes a housing sized to fit in a palm of a user, an elongate drive tube configured to be rotated by the housing, the drive tube including an axially extending passage, a cylindrical member, configured to be rotationally coupled to the drive tube, such that a distal tip of the cylindrical member may be delivered to a location adjacent the arterial occlusion when the cylindrical member is coupled to the drive tube, and wherein grasping and activating the housing such that the drive tube is rotated, thereby causes the distal tip of the cylindrical member to be rotated, the rotation of the distal tip including at least a component of linear oscillation.
Claims18
A method for configuring a system for traversing an arterial occlusion in an artery comprising:
- providing a housing sized to fit in a palm of a user;
- providing a rotary actuator comprising:
- a manipulation member, moveably coupled to the housing, and
- an elongate drive tube rotationally disposed within the housing and configured to be rotated by thumb-activated movement of the manipulation member with respect to the housing, the drive tube having a first end and a second end and including a passage extending axially from the first end to the second end;
- and
- rotationally coupling a cylindrical member to the drive tube, the cylindrical member having a distal tip that is configured to be delivered to a location adjacent an arterial occlusion when the cylindrical member is coupled to the drive tube, such that thumb-activated movement of the manipulation member directly causes substantially only rotational movement of the cylindrical member, and wherein the rotating cylindrical member as a result of its rotational movement in turn effects a cyclic axial impact of the distal tip of the cylindrical member.
A method for using a system for traversing an arterial occlusion in an artery, the system having a housing sized to fit in a palm of a user, a rotary actuator including a manipulation member moveably coupled to the housing, and an elongate drive tube rotationally disposed within the housing and configured to be rotated by thumb-activated movement of the manipulation member with respect to the housing, the drive tube having a first end and a second end and including a passage extending axially from the first end to the second end, the method comprising:
- rotationally coupling a cylindrical member to the drive tube, the cylindrical member having a distal tip that is configured to be delivered to a location in an artery when the cylindrical member is coupled to the drive tube;
- positioning the distal tip of the cylindrical member adjacent to an arterial occlusion;
- and
- moving the manipulation member using at least a thumb to directly cause substantially only rotational movement of the cylindrical member, and wherein the rotating cylindrical member as a result of its rotational movement in turn effects a cyclic axial impact of the distal tip of the cylindrical member in relation to the arterial occlusion.
