A sealing apparatus includes a housing mountable to an elongate shaft having an axial lumen, a sealing element mounted within the housing and having a dome portion with an opening for passage of an object and at least partially defining an arcuate pathway within the housing, and a sealing member defining a cavity for receiving the object in sealing relation therewith. The sealing member is partially disposed within the housing, and is supported in direct contact with the dome portion of the sealing element. The sealing member is adapted to form a substantial seal with the sealing element, and to spherically move through the arcuate pathway relative to the sealing element upon offset manipulation of an object.

A sealing apparatus comprising: a housing being mountable to an elongate shaft including an axial lumen;a sealing element mounted within the housing, the sealing element having a dome portion having an opening for passage of an object and at least partially defining an arcuate pathway within the housing; anda sealing member defining a cavity for receiving the object in sealing relation therewith and having at least a portion thereof disposed within the housing, the sealing member being supported in direct contact with the dome portion of the sealing element and adapted to form a substantial seal therewith and to spherically move through the arcuate pathway relative to the sealing element upon offset manipulation of an object. 2. The sealing apparatus of claim 1, wherein the sealing member includes a spherical flange and the housing includes an inner surface having a substantially spherical configuration and defining with the sealing element the arcuate pathway for spherical movement of the sealing member. 3. The sealing apparatus of claim 1, wherein the sealing member has a base configured to cooperate with a spherical surface of the sealing element. 4. The sealing apparatus of claim 1, wherein the housing comprises a cannula housing and retainer. 5. The sealing apparatus of claim 4, wherein the cannula housing includes a sealing valve, the sealing valve adapted and dimensioned to open in the presence of the object and substantially close in the absence of the object. 6. The sealing apparatus of claim 5, further comprising a stabilizing plate having an opening and being mounted onto the seal valve and cannula housing for retention of the sealing valve. 7. The sealing apparatus of claim 6, wherein the retainer comprising an opening for receipt of the object, the retainer being mounted with the sealing element. 8. A surgical sealing apparatus to be associated with an elongated cannula adapted to access tissue, the sealing apparatus comprising: a housing segment adapted for mounting to an elongated cannula and defining a central longitudinal axis;a retainer segment coupled to the housing segment and having an arcuate inner surface;a sealing element operatively coupled to one of the housing segment and the retainer segment, the sealing element having a central dome segment defining an opening therethrough, the dome segment dimensioned to cooperate with the arcuate inner surface of the retainer segment to define an arcuate pathway; anda seal mounted within the arcuate pathway, and adapted to receive a surgical object in substantial sealing relation therewith, the seal being supported in direct contact with the dome segment of the sealing element and adapted to traverse the arcuate pathway during offset manipulation of the surgical object. 9. The surgical sealing apparatus according to claim 8, wherein the sealing element comprises a resilient material and is dimensioned to cooperate with the seal to establish a substantial sealing interface between the central dome segment of the sealing element and the seal. 10. The surgical sealing apparatus according to claim 8, wherein the seal includes a peripheral flange segment and an inner seal segment depending radially inwardly from the peripheral flange segment. 11. The surgical sealing apparatus according to claim 10, wherein the peripheral flange segment is dimensioned and configured to establish a substantial sealing relation with the arcuate inner surface of the retainer segment. 12. The surgical sealing apparatus according to claim 11, wherein the peripheral flange segment defines an outer arcuate surface in contacting substantial sealing relation with the arcuate inner surface of the retainer segment. 13. The surgical sealing apparatus according to claim 12, wherein the peripheral flange segment includes a base surface in contacting and substantial sealing relation with the dome segment of the sealing element. 14. The surgical sealing apparatus according to claim 8, wherein the seal is adapted to traverse the arcuate pathway and move about at least two axes of movement upon manipulation of the surgical object, a first of the axes being a pivotal axis extending transverse to the longitudinal axis and being distal of the sealing member, and a second of the axes being a rotation axis extending in general parallel relation with the longitudinal axis. 15. The surgical sealing apparatus according to claim 14, including a valve at least partially disposed within the housing, the valve adapted to substantially close in the absence of the surgical object. 16. The surgical sealing apparatus according to claim 1, wherein the housing defines an upper inner surface, the upper inner surface and the dome portion of the sealing element defining the arcuate pathway. 17. The surgical sealing apparatus according to claim 16, wherein upper inner surface has a substantially spherical configuration. 18. The surgical sealing apparatus according to claim 16, wherein at least a portion of the sealing member remains in contact with the upper inner surface as the sealing member spherically moves through the arcuate pathway. 19. The surgical sealing apparatus according to claim 16, wherein the upper inner surface and the dome portion of the sealing element have complementary mating surfaces. 20. The surgical sealing apparatus according to claim 8, wherein the opening has proximal and distal ends, the proximal end having a diameter smaller than the diameter of the distal end.
