1. An apparatus comprising:
- a cutting element slidably disposed within a lumen of a shaft, wherein the cutting element includes a proximal end and a distal end; and
an actuating element having a proximal end and a distal end, wherein the distal end of the actuating element is operationally coupled to the proximal end of the cutting element such that when the actuating element is displaced the cutting element rotates and the distal end of the cutting element protrudes from a side window which is located at a distal portion of the shaft.

Abstract
A mechanical cavity-creation surgical device and methods and kits for using such devices is described. In one variation, the mechanical cavity-creation surgical device contains a side window at the distal end of a shaft that allows the articulation of a blade, pick, or tip from a position that is inside the shaft to a position that protrudes at least partially from the side window.

- 23. A surgical instrument comprising a 1) shaft, 2) a cutting element and 3) a guide, the shaft having a lumen inside the shaft, the shaft having a proximal end and a distal end, the distal end of the shaft having a slot that runs essentially parallel to the shaft, the proximal end of the shaft connected to a handle, and the handle having an actuator wherein the actuator is operationally coupled to the guide such that when the actuator is manipulated by a user, the cutting element articulates from a position that is inside the lumen to a position protruding through the slot on the shaft.

35. A method of creating a cavity in a body region comprising:
-
inserting a distal portion of a shaft into a patient'"'"'s body;
rotating a cutting element within a lumen of the shaft which results in a distal portion of the cutting element protruding from a side window on the shaft, wherein the side window is located on a circumferential surface at a distal portion of the shaft; and
rotating the shaft axially to score or scrape a body region within the patient'"'"'s body to create a cavity. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
