1. A cutting apparatus comprising:
- (a) a handle;
(b) an insertion tube, the insertion tube being associated with the handle;
(c) an end effector, the end effector being associated with the insertion tube, wherein the end effector further includes;
(i) a body, the body having a proximal portion and a distal portion;
(ii) an aperture formed in the body;
(iii) a transverse member, the transverse member being positioned within the aperture of the body adjacent the distal end of the body;
(iv) a cutting member, the cutting member including an elongated portion having a first end and a second end, wherein the first end of the cutting member is coupled with the proximal portion of the body of the end effector and the elongated portion is wrapped around the transverse member; and
(d) an elongate shaft, the shaft being associated with the second end of the cutting member, wherein the shaft is associated with the cutting member such that distally translating the shaft urges the cutting member outward through the aperture of the end effector and proximally translating the shaft retracts the cutting member into the aperture and against the transverse member.

Abstract
Provided is a minimally invasive cavity formation instrument for forming tissue cavities. The instrument includes an end effector having an aperture through which a cutting element is laterally extended and retracted. The cutting element may be retracted for minimally invasive insertion into a tissue region and extended to form a tissue cavity. The end effector of the instrument may be articulated or rotated to facilitate cavity formation.
