    Abstract: A surgical access device includes a single valve forming a seal with the body wall and providing an access channel into a body cavity. The valve has properties for creating a zero-seal in the absence of an instrument and an instrument seal with instruments. The valve can include a gel comprised of an elastomer and oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon. A method for making the surgical access device includes combining a gelling agent with oil, preferably in a molding process. A method for using the device includes creating an opening with the instrument. An organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity.

    Abstract: A pneumatic tissue dissector 10 useful for cutting or dissecting living tissue during endoscopic or laparoscopic procedures includes a dissector tip 16 for exuding a flow of pressurized gas, an inlet arrangement 24 for controlling the flow of gas from the tip 16, and an exhaust system 30 for exhausting the gas exuded from the tip 16. The exhaust system includes an inlet 32 adjacent to the tip 16 and an outlet spaced from the inlet 32. The outlet 34 is operable in coordination with the inlet arrangement 24 and is capable of exhausting a flow of gas about equal to that exuded by the tip 16, ensuring that the pressure in the cavity in which the procedure is performed does not increase or fluctuate. The flow of pressurized gas from the tip 16 is preferably compatible with an insufflation cavity pressure of no more than about 15 mm Hg, and the inlet arrangement 24 preferably supplies gas to the tip 16 at a pressure of no more than about 50 psi. The dissector 10 preferably further includes a laparoscopic introducer sheath 68 which is shorter in length than the distance between the inlet 32 and the outlet 34.

    Abstract: A surgical tissue bag for percutaneously debulking large volumes of tissue contained within the bag. The tissue bag comprises two layers of material, an inner layer of a puncture-resistant material and an outer layer of moisture-proof material for containing cells and fluid therein. The bag material is foldable and flexible for insertion through an access sheath into the surgical site and for forming a gas-tight seal when extended through the access sheath or puncture site. A drawstring is attached to the open end of the bag to close the bag when the tissue is contained therein and pulled through the puncture site in the outer surface of the skin. After the closed open end of the bag is pulled through the puncture site, the closed end is fanned out against the outer layer of the skin, and a morcellator is inserted into the bag for debulking the large volume of tissue. The open end of the bag is continually fanned out to maintain a compact and tight containment of the tissue and fluid remaining in the bag. The morcellation process is continued until the entire volume of tissue is removed at which time the remaining portion of the bag is completely removed from the surgical site area.
