Abstract
A tissue removal kit or assembly comprises a cannula and a tissue removal probe axially slidable within the cannula. The tissue removal probe comprises an elongated member a distal end configured to curve when distally deployed from the cannula. The tissue removal probe further comprises a drive shaft rotatably disposed within the member, and a rotatable tissue removal element (e.g., an abrasive burr) disposed on the drive shaft adjacent the member distal end. The curved member distal end may associate the tissue removal element, which has its own axis of rotation, with a radius of revolution about the longitudinal axis of the member. The member is laterally flexible and resilient, so that the radius of revolution can be adjusted. In this manner, the tissue removal element can remove tissue around an adjustable arc.
