Abstract: A thin, flexible patch for decompressing a hollow structure, such as an ovarian cyst is applied to the hollow structure during a surgical procedure. The patch is adhered to the structure by an adhesive layer to form a fluid-tight seal with the structure. During the surgical procedure, such as a laparoscopic procedure, an aspiration needle is inserted through the patch and into the hollow structure with the patch forming a fluid-tight seal around the needle. Fluid is withdrawn by the aspiration needle, causing the structure to decompress and to be reduced in size. Once the structure is reduced in size it can be removed, for example, through a minimally invasive surgical port. The patch includes handles that facilitate grasping and manipulating the structure using laparoscopic instruments. The patch may also be formed by applying a curable material to the hollow structure and curing the material in situ so that it forms a patch that is adhered to the structure.

Abstract: An intra-corporeal surgical retractor for holding tissues and organs in place is provided, including a sealed container, made from a flexible material, having an interior containing a granular substance and a fluid. At least one tube may be provided with one end attached to the container in communication with the interior of the container and the other end connected to a suction mechanism. When the fluid is evacuated from the container, the container constricts around the granular substance and becomes relatively rigid. An absorbent sleeve or layer may be provided surrounding the container. The granular substance may be provided as loose fill or as a layer over at least a portion of the inner wall. Alternatively, the inner walls of the container may be provided with a very rough surface. Further, the outer surface of the bottom of the pouch is enhanced frictionally.
