An apparatus for separating a first layer of tissue, such as the peritoneum, from a second layer of tissue, such as the properitoneal fascia. The apparatus includes a main envelope that defines a main inflatable chamber. The apparatus also includes an introducing device that introduces the main envelope in a collapsed state between the first layer of body tissue and the second layer of tissue. The introducing device also inflates the main envelope into an expanded state to separate the first layer of tissue from the second layer of tissue, and to create a working space between the two layers of tissue. Finally, the apparatus includes an insufflating device with a gas-tight seal that introduces insufflation gas into the working space between the two layers of tissue to maintain the working space after at least partial deflation of the main envelope.
