Single port device with multi-lumen cap
First Claim
1. A surgical access apparatus, which comprises:
- an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object; and
an access housing including a diaphragm having proximal and distal surfaces, the diaphragm being positioned within the access housing and mounted to the access housing such that the proximal surface of the diaphragm is fixedly positioned along the longitudinal axis, whereby the proximal surface of the diaphragm remains in a substantially constant location along the longitudinal axis during use of the surgical access apparatus, the diaphragm being adapted for rotational movement about the longitudinal axis relative to the access housing, the diaphragm defining at least one internal pocket, and having a seal assembly disposed within the internal pocket, the seal assembly having an interface seal member adapted for establishing a fluid tight seal about the surgical object, the seal assembly and the at least one internal pocket including corresponding structure in cooperative engagement to facilitate selective movement of the seal assembly within the pocket about multiple axes in response to manipulation of the surgical object.

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 surgical access apparatus, which comprises:
-
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 including; a diaphragm having proximal and distal surfaces, the diaphragm being positioned within the access housing and secured to the access housing such that the proximal surface of the diaphragm is fixedly positioned along the longitudinal axis, whereby the proximal surface of the diaphragm remains in a substantially constant location along the longitudinal axis during use of the surgical access apparatus, the diaphragm being rotatable about the longitudinal axis relative to the access housing, and including a pocket defining a cavity; and a seal assembly disposed within the cavity, the seal assembly and the cavity including corresponding arcuate surfaces configured and dimensioned for cooperative engagement to facilitate selective articulation of the seal assembly about a plurality of axes. - View Dependent Claims (16, 17)
