  • Patent number: 8968249
    Abstract: A seal assembly for use with an access device includes a seal housing defining a central longitudinal axis, an inner wall and an outer wall. The inner wall defines a longitudinal opening to permit passage of instrumentation through the seal housing. A gimbal mount is at least partially accommodated within a space defined between the inner wall and the outer wall of the seal housing. The gimbal mount includes a seal member defining an aperture for substantial sealed reception of a surgical instrument. The gimbal mount is adapted for angular movement relative to the central longitudinal axis upon angulation of the surgical instrument while substantially maintaining the sealed reception of the surgical instrument.

  • Patent number: 8801752
    Abstract: A surgical device for performing surgery generally includes a handle assembly, an elongate member extending from the handle assembly, an articulation mechanism operatively associated with the handle assembly, and an end effector. The elongate member has an articulating section and straight section. The articulating section is configured to articulate with respect to the straight section. The articulation mechanism is operatively associated with the handle assembly and the articulating section such that the articulating section articulates toward a first direction relative to the straight section upon movement of the handle assembly towards the first direction with respect to the straight section. The end effector is operatively coupled to the articulating section of the elongate member and includes first and second jaw members. The surgical device further includes a locking mechanism configured for fixing a relative position of first and second jaw members.

  • Publication number: 20140171744
    Abstract: 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.
