摘要： A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.

摘要： An incrementally adjustable wound retractor (500), having a first ring (504) with a diameter greater than the desired diameter of the wound incision, a flexible second ring (502), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (506), disposed in a generally cylindrical form between the first and second rings (502, 504), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.
