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.
