Abstract:
1. A tissue removal device, comprising: an elongate body having an inner lumen extending from a proximal portion to a distal end; an elongate member extending through the lumen, the member having a long axis and a distal portion that extends in a direction transverse to the long axis, the elongate member long axis being eccentrically positioned relative to a central long axis of the elongate body, the member configured for axial movement and rotational movement relative to the elongate body when extending through the lumen, the axial movement permitting the distal portion of the elongate member to be positioned distally of the distal end of the elongate body by distal advancement of the elongate member relative to the elongate body, wherein the rotational movement is relative rotation between the elongate body and the elongate member about the long axis; and an actuator attached to the proximal portion of the elongate body and configured to control at least one of the axial movement or the rotational movement of the elongate member relative to the elongate body; wherein, upon insertion of the device into a patient and actuation of the actuator, the elongate member is configured to cut a tissue in the patient by the at least one of the axial movement or the rotational movement; and wherein an end of the distal portion is movable from within a perimeter of the elongate body to beyond the perimeter by the rotational movement of the elongate member relative to the elongate body.
