Methods of using inflatable retraction devices in laparoscopic surgery
First Claim
1. A method for properitoneal hernia repair, the method comprising the steps of:
- providing an inflatable retraction device in a compacted state, the inflatable retraction device including;
a main envelope enclosing a main chamber, the main envelope including a window and a removable window,a second envelope covering substantially all the main envelope, except the window and the removable window, the second envelope and the main envelope enclosing a second chamber outside the main chamber,an attachment point centered in the removable window, andan insertion shaft passing through the main chamber, and having a distal end temporarily attached to the attachment point, the attachment point providing a distal tip for the inflatable retraction device;
making an incision through the abdominal wall at the umbilicus as far as the properitoneal layer;
inserting the distal tip of the inflatable retraction device into the incision;
using the inflatable retraction device to dissect the peritoneum from the properitoneal layer while advancing the inflatable retraction device inferiorly between the peritoneum and the properitoneal layer towards the hernia;
passing a fluid into the main chamber to expand the main chamber and the second chamber from the compacted state to dissect further the peritoneum from the properitoneal layer;
passing a fluid into the second chamber to further expand the second chamber;
releasing fluid from the main chamber; and
detaching the removable window from the main envelope.

Abstract
Apparatus for retracting an organ to gain access to treat a tissue. The apparatus has a main envelope, a second envelope, a first inflation device and a second inflation device. The main envelope encloses a main chamber, and includes a window and a removable window. The second envelope covers substantially all the main envelope, except the window and the removable window. The second envelope and the main envelope enclose a second chamber outside the main chamber. The first inflation device passes a fluid into the main chamber to expand the main chamber and the second chamber from a compacted state to retract the organ. The second inflation device passes a fluid into the second chamber to further expand the second chamber to maintain the organ in its retracted state after fluid has been released from the main chamber.
