Abstract
A surgical access assembly includes an access port and a seal anchor. The access port includes a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough. In particular, the proximal, intermediate and distal rings are concentrically arranged with the passage of the sleeve, and the sleeve extends between the proximal and distal rings. The seal anchor is adapted to be at least partially disposed in the access port, and defines a lumen therethrough. At least one of the proximal, intermediate, and distal rings is configured and dimensioned to engage the seal anchor in a sealing relation therewith.

A surgical access assembly comprising:
- an access port including a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough, the proximal, intermediate and distal rings concentrically arranged with the passage of the sleeve, the sleeve extending between the proximal and distal rings;
- and
- a seal anchor adapted to be at least partially disposed in the access port, the seal anchor defining a lumen therethrough, wherein at least one of the proximal, intermediate and distal rings is configured and dimensioned to engage the seal anchor in a sealing relation therewith.
A method of accessing an internal body cavity, comprising:
- providing a surgical access assembly including:
- an access port having a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough, the proximal, intermediate and distal rings concentrically arranged with the passage of the sleeve, the sleeve extending between the proximal and distal rings;
- and
- a seal anchor adapted to be at least partially disposed in the access port, the seal anchor defining a lumen therethrough;
- positioning at least one of the proximal, intermediate, and distal rings of the access port into the body cavity;
- rolling the sleeve of the access port such that at least two of the proximal, distal and intermediate rings engage an internal peritoneal wall of tissue and an outer epidermal tissue;
- positioning the seal anchor within the access port;
- and
- introducing a surgical instrument to the body cavity through the seal anchor.
