ABSTRACT:
A system for separating a first layer of tissue from a second layer of tissue and for maintaining separation of the first layer of tissue from the second layer of tissue while providing access to at least one of the layers of tissue. The system comprises a main envelope which defines a main inflatable chamber, an introducing means and an insufflating means. The introducing means includes a main cannula portion to which the main envelope is attached. The introducing means is for introducing the main envelope in a collapsed state between the first layer of tissue and the second layer of tissue, and for inflating 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 first layer of tissue and the second layer of tissue. The insufflating means includes an auxiliary cannula portion to which an auxiliary envelope defining an auxiliary inflatable chamber is attached. The insufflating means is for introducing insufflation gas into the working space to maintain the separation of the first layer of tissue from the second layer of tissue.
