Abstract
Abstract A seal assembly is provided which includes a gimbal-like structure permitting rotation of a mounting member relative to the housing. The rotation of the mounting member allows the seal member to align with an instrument being inserted therethrough. The seal assembly is adapted to be detachably mounted to a cannula assembly for use in endoscopic surgery.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
88 words
A seal assembly which comprises: (i) a housing having a passage defining a longitudinal axis and disposed between at least two open ends, (ii) a mounting member rotatably mounted within said housing, and (iii) a seal member at least partially disposed within said passage and mounted to said mounting member, said seal member having an aperture formed therein through which a surgical instrument may pass; wherein rotation of said mounting member relative to said housing angularly displaces said aperture of said seal member relative to said longitudinal axis.
Claim 2
Dependent Claim
88 words
A seal assembly which comprises: (i) a housing having a passage defining a longitudinal axis and disposed between at least two open ends, (ii) a mounting member rotatably mounted within said housing, and (iii) a seal member at least partially disposed within said passage and mounted to said mounting member, said seal member having an aperture formed therein through which a surgical instrument may pass; wherein rotation of said mounting member relative to said housing angularly displaces said aperture of said seal member relative to said longitudinal axis.
