ABSTRACT:
An apparatus and method for separating tissue layers and providing a working space for performing a medical procedure. A first balloon is inserted between the tissue layers and inflated to dissect the tissue layers. A second balloon is also positioned between the tissue layers and inflated to retract the tissue layers. The first balloon is then deflated and punctured with a sharp instrument to created an opening in the first balloon. The second balloon is positioned to impede the escape of insufflation fluid from the working space and the working space is then insufflated. An instrument for performing the medical procedure may then be introduced into the working space through the opening in the first balloon.
