    Abstract: A surgical access device includes an access seal comprising an ultra gel elastomeric material formed of a mixture comprising a triblock copolymer and an oil. The access seal is adapted to be disposed relative to the abdominal wall. At least one access channel is formed through the elastomeric material between a proximal portion and a distal portion of the access seal. The access channel when operatively disposed forms at least a portion of a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The elastomeric material of the access seal is adapted to conform to a surface of an instrument inserted through the working channel to provide instrument access to the abdominal cavity while maintaining insufflation pressure in the abdominal cavity. The access channel is configured to self seal in the absence of any instrument extending through the access channel.

    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 trocar access sheath having a laterally expandable retention mechanism for percutaneous insertion through a body cavity wall. The expandable retention mechanism is positioned about the distal end of the sheath for retaining the access sheath within the body cavity. The access sheath has an inner elongated member cannula and an outer elongated member tube having a slick surface for ready insertion through a puncture site. The laterally expandable retention mechanism includes a plurality of strips extending and formed longitudinally in the outer tube. The retention mechanism has an expanded state and a retracted state. In the expanded state, the longitudinal strips extend radially from the outer elongated member tube to engage the interior surface of the body cavity wall. The expandable retention mechanism is actuated by sliding an actuating mechanism hub attached to the distal end of the outer elongated member tube against another hub fixedly attached to the inner elongated member cannula. To insert or retract the access sheath through the cavity wall of a patient, the physician squeezes the actuating mechanism hub against the fixed hub to collapse the longitudinal strips against the surface of the inner elongated member cannula. Once inserted, the actuating mechanism is released to expand the retention mechanism.

    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.
