1. A method of providing access to an anatomical structure in an anatomical region within a body, the method comprising the steps of:
- providing an apparatus including a cannula, an inflatable balloon having a longitudinal axis and shaped for use in the anatomical region, wherein the balloon has a distal portion and a proximal portion, where the diameter, volume or perimeter of the balloon when inflated generally decreases from the proximal portion towards the distal portion of the balloon, and an inflation lumen having access to the interior of the balloon for inflating the balloon;
making an incision in a body;
inserting the balloon through the incision into the anatomical region;
directing the balloon to the vicinity of the anatomical structure; and
inflating the balloon to dissect tissue in the anatomical region to provide access to the anatomical structure such that the amount of dissection varies along the longitudinal axis of the balloon.

Abstract
A balloon device useful for dissecting tissue or retracting tissue for the purpose of providing access for laparoscopic surgery, the device comprising 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.

15. An apparatus for dissecting tissue to facilitate a laparoscopic surgical procedure in an anatomical region of a patient'"'"'s body, the apparatus comprising:
-
a cannula having an end which is insertable through a laparoscopic incision in the patient'"'"'s body;
a coupling structure which couples the balloon to the cannula, where the coupling structure releases the balloon from the cannula when the balloon is inflated;
an inflatable balloon coupled to the cannula, the balloon being inflatable to a shape suitable for the laparoscopic surgical procedure and the anatomical region of the patient'"'"'s body in which the balloon is to be used, where the shape of the balloon allows the inflation of the balloon to cause a non-uniform dissection of tissue, wherein the balloon has a distal portion and a proximal portion, where the diameter, volume or perimeter of the balloon when inflated generally decreases from the proximal portion towards the distal portion of the balloon; and
a lumen which provides access to the interior of the balloon for inflating the balloon with a fluid. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
