ACCESS PORT INCLUDING ROTATABLE SEALS A surgical access device (1000) includes a housing (1002); an access member (1006) extending distally from the housing (1002) and being dimensioned for positioning 5 within tissue, and defining a longitudinal axis; and a seal assembly (100) disposed within the housing (1002). The seal assembly (100) includes first and second seal components (1 02a, 102b) respectively having first and second seal members. Each of the first and second seal members (1 12a, 112b) defines a passage (1 14a, I 14b) for passage of a surgical object in substantial sealed relation therewith. The first and second seal io components (102a, 102b) are capable of relative rotation about the longitudinal axis between a first position, in which passages of the first and second seal members (I 12a, 112b) are in substantial alignment, and a second position where the passages of the first and second seal members (1 12a, I 12b) are offset to inhibit the communication of fluid through the seal assembly (100). / -- ~~ ~ -1006 :: A 1008- I I I Ii. 114b 114bb 115b (104b |
