摘要： A device comprises an access port adapted to permit access of at least one surgical instrument into a patient. The access port comprises a proximal portion, a distal portion, and an intermediate portion monolithically formed of a flexible material. At least one opening extends through the access port. The proximal portion comprises a proximal flange. The distal portion comprises a distal flange. The intermediate portion comprises an outer surface and at least one inner surface. The access port is adapted to form a perimeter seal when the proximal flange is disposed exteriorly and the distal flange is disposed interiorly. The access port is adapted to form a seal with the at least one surgical instrument positioned through the access port. The intermediate portion conforms to the surface of the surgical instrument positioned through the at least one opening and forms the seal between the inner surface and the surgical instrument.

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 100 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 seal assembly for reception of an elongated surgical instrument is provided which includes a body having at least one opening configured and dimensioned to permit entry of an elongated surgical instrument and defining a central longitudinal axis; a seal member formed of a resilient material and defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument in a substantially fluid tight manner; and a fabric layer juxtaposed relative to the resilient material. A coating may be applied to the seal member to reduce friction between the seal member and surgical instrumentation inserted therein. The coating is preferably a hydrocyclosiloxane membrane prepared by plasma polymerization process.

摘要： An access apparatus for use in surgical procedures is provided. The access apparatus includes a control mechanism that is configured to control desufflation flow of the access apparatus. The control mechanism includes a valve in fluid communication with a longitudinal passage that is operably associated with the access apparatus. The valve includes one or more openings and a selectively movable mechanical interface that operably couples to the valve. The selectively movable mechanical interface is configured to alter desufflation flow when it is moved with respect to the valve and across the at least one opening.

摘要： A valve assembly for the sealed reception of an elongated object is provided. The assembly includes a valve body defining at least one opening configured and dimensioned to permit entry of an elongated object and defining a central longitudinal axis, and an elongated seal member having a resilient sealing structure and defining an aperture in general alignment with the opening of the valve body whereby the aperture is configured and dimensioned such that upon insertion of the object into the aperture, the resilient sealing structure resiliently engages the outer surface of the object in a tight manner. The sealing structure includes a plurality of elongated bristle members attached to the seal member. The bristle members are positioned to engage the elongated object upon at least partial insertion of the elongated object into the valve body. Each bristle member is adapted to be displaced relative to the longitudinal axis to facilitate expansion of the aperture of the seal member upon entry of the elongated object therein.
