The present disclosure relates to a valve or seal of the type adapted to allow the introduction of an instrument or object therethrough. In particular, the valve disclosed herein is adapted to maintain a substantially fluid-tight seal with a surgical instrument and is used during a minimally invasive surgical procedure. The valve disclosed herein incorporates one or more bladder members adapted to retain a fluid therein that are associated by one or more interstitial members.

대표청구항 ▼

1. A surgical portal apparatus, which comprises: a portal member defining a longitudinal axis and having a longitudinal opening for passage of a surgical object, the portal member dimensioned for insertion through body tissue to provide access to an underlying surgical site; anda valve mounted to the portal member and defining a valve axis extending therethrough, the valve dimensioned and adapted for reception of the surgical object in substantial sealed relation therewith, the valve including: at least one membrane defining a passage for introduction of the surgical object and having an internal cavity; andat least two bladder members disposed within the internal cavity of the at least one membrane, the at least two bladder members each having a fluid therein and being arranged in spaced relation with respect to the valve axis to at least partially surround the passage of the at least one membrane, the at least two bladder members cooperating with the at least one membrane to establish the substantial sealed relation with the surgical object. 2. The surgical portal apparatus of claim 1, wherein the at least one membrane includes an inner membrane segment and an outer membrane segment. 3. The surgical portal apparatus of claim 1, wherein the at least one membrane is formed of an at least semi-resilient material. 4. The surgical portal apparatus of claim 1, wherein the at least two bladder members are connected to the at least one membrane. 5. The surgical portal apparatus of claim 2, wherein the inner and outer membrane segments define the internal cavity therebetween. 6. The surgical portal apparatus of claim 5, further including a first fluid disposed within each of the at least two bladder members. 7. The surgical portal apparatus of claim 6, further including a second fluid disposed within the internal cavity of the at least one membrane and surrounding the at least two bladder members. 8. The surgical portal apparatus of claim 6, further including at least one interstitial member disposed between the at least two bladder members, the at least one interstitial member is configured to facilitate communication of fluid between the at least two bladder members. 9. The surgical portal apparatus of claim 8, wherein the at least one interstitial member defines a lumen therethrough. 10. The surgical portal apparatus of claim 8 wherein the at least two bladder members are arranged in a substantially annular configuration within the cavity. 11. The surgical portal apparatus of claim 10, wherein the at least two bladder members are arranged in at least two concentric rings within the cavity. 12. The surgical portal apparatus of claim 11, wherein the at least two concentric rings include an inner ring and an outer ring. 13. A surgical portal apparatus, which comprises: a portal member defining a longitudinal axis and having a longitudinal opening for passage of a surgical object, the portal member dimensioned for insertion through body tissue to provide access to an underlying surgical site; anda valve mounted to the portal member and defining a valve axis extending therethrough, the valve dimensioned and adapted for reception of the surgical object in substantial sealed relation therewith, the valve including: a valve membrane; anda plurality of bladder members disposed within the valve membrane, the bladder members being in fluid communication and having a fluid dimensioned to communicate between the bladder members to accommodate manipulation of the surgical object. 14. The surgical portal apparatus of claim 13, wherein each of the plurality of bladder members defines at least one aperture that is in fluid communication with at least one interstitial member, the at least one interstitial member being disposed between adjacent bladder members. 15. The surgical portal apparatus of claim 14, wherein the at least one interstitial member defines a lumen therethrough that is substantially aligned with the at least one aperture. 16. The surgical portal apparatus of claim 7 wherein the first fluid is different from the second fluid. 17. The surgical portal apparatus of claim 16 wherein one of the first and second fluids includes air. 18. The surgical portal apparatus of claim 17 wherein the first and second fluids are liquids. 19. The surgical portal apparatus of claim 7 wherein one of the first and second fluids includes air.
