1. An apparatus for dissecting tissue to facilitate a laparoscopic surgical procedure in an anatomical region of a patient'"'"'s body, the apparatus comprising:
- (a) a cannula having an end which is insertable through a laparoscopic incision in the patient'"'"'s body;
(b) a deflated inflatable balloon coupled to the cannula, the balloon having a distal end, a proximal end, and a neck portion adjacent the proximal end, where a width of the inflated balloon is at a maximum at the proximal end adjacent the neck portion and immediately decreases towards the distal end of the balloon and causes a non-uniform dissection of tissue, and a portion of the balloon is inverted into another portion of itself to reduce the length of the deflated balloon; and
(c) a lumen which provides access to the interior of the balloon for inflating the balloon with a fluid.

Abstract
A balloon device useful for dissecting tissue or retracting tissue for the purpose of providing access for laparoscopic surgery, the device including a balloon which inflates to a shape specially suitable for the surgical procedure and the anatomical region of deployment. The present device, when configured with a tapered dissection balloon, is particularly useful for subfascial endoscopic perforator surgical procedures.

13. An apparatus for dissecting tissue to facilitate a laparoscopic surgical procedure in a patient'"'"'s body comprising:
-
(a) A cannula having an end which is insertable through a laparoscopic incision in the patient'"'"'s body; (b) A deflated inflatable balloon mounted to the cannula, the balloon having a distal end, a proximal end, and a neck portion adjacent the proximal end, where the width of the distal end of the balloon is smaller than the width of the proximal end of the balloon such that the inflated balloon is generally tapered from the proximal end towards the distal end, and a portion of the balloon is inverted into another portion of itself to reduce the length of the deflated balloon; and (c) a lumen which provides access to the interior of the balloon for inflating the balloon with a fluid. - View Dependent Claims (14)
