Single port device with multi-lumen cap
First Claim
1. A surgical access apparatus for insertion into an opening in tissue during a surgical procedure, comprising:
- an access housing including a diaphragm having proximal and distal surfaces, the diaphragm being positioned within the access housing; and
an access member extending distally from the access housing along a longitudinal axis and having a longitudinal passageway for reception and passage of at least one surgical object, the access member including a plurality of concentrically oriented inflatable chambers each defining an outer dimension extending transversely in relation to the longitudinal axis, the outer dimensions defined by the inflatable chambers being unequal such that the access member includes a tapered configuration.

Abstract
A surgical access apparatus includes an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object and an access housing mountable to the access member. The access housing includes a diaphragm mounted thereto. The diaphragm is adapted for rotational movement about the longitudinal axis relative to the access housing. The diaphragm defines at least one internal pocket and has a seal assembly disposed within the internal pocket. The seal assembly has an interface seal member adapted for establishing a fluid tight seal about the surgical object. The seal assembly is adapted for selective movement within the pocket about multiple axes in response to manipulation of the surgical object.

15. A method of accessing an internal surgical worksite through an opening in tissue comprising:
-
positioning an access apparatus within the opening in the tissue such that a housing of the access apparatus remains external of the surgical worksite, and at least a portion of an access member of the access apparatus extends beneath the tissue into the surgical worksite; inflating the access member to cause a plurality of concentrically oriented inflatable chambers comprising the access member to expand such that each inflatable chamber defines an enlarged outer dimension extending transversely in relation to a longitudinal axis of the access member, wherein the outer dimensions defined by the inflatable chambers are unequal such that the access member includes a tapered configuration; and inserting at least one surgical object into the surgical worksite through the access apparatus. - View Dependent Claims (16, 17, 18, 19, 20)
