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.

Claims

1. 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 sleeve extending between the proximal and distal rings, the proximal ring being rollable to adjust a length of the sleeve, the proximal ring having a non-circular cross-section; and

a seal anchor having a proximal end, a distal end, and an intermediate portion extending between the proximal and distal ends, the seal anchor adapted to be at least partially disposed in the access port, the seal anchor defining a lumen therethrough, wherein the distal ring is configured and dimensioned to engage the intermediate portion of the seal anchor in a sealing relation therewith, the seal anchor having a diameter larger than a diameter of the distal ring, the diameter of the seal anchor that is larger than the diameter of the distal ring is dimensioned to be received through the proximal and intermediate rings such that the distal ring and a portion of the seal anchor are adapted to be disposed beneath an outer surface of a tissue.

2. The surgical access assembly according to claim 1, wherein at least one of the distal or intermediate rings is an O-ring.

3. The surgical access assembly according to claim 2, wherein the O-ring is an inflatable balloon.

4. The surgical access assembly according to claim 1, wherein the seal anchor defines an hourglass shape.

5. The surgical access assembly according to claim 1, wherein at least one of the proximal, distal, or intermediate rings is elastic.

6. The surgical access assembly according to claim 1, wherein the proximal ring has a kidney-shaped cross-section.

7. The surgical access assembly according to claim 1, wherein the sleeve is formed of an elastic material.

8. The surgical access assembly according to claim 1, wherein the seal anchor is formed of a compressible material.

9. The surgical access assembly according to claim 1, wherein the lumen of the seal anchor is dimensioned to receive a surgical instrument therethrough.

10. The surgical access assembly according to claim 1, wherein at least one of the proximal, distal, or intermediate rings is an inflatable balloon.

11. The surgical access assembly according to claim 1, wherein the seal anchor defines a circumferential groove dimensioned to receive one of the proximal, intermediate, or distal rings.

17. The surgical access assembly according to claim 1, wherein the sleeve connects the proximal, intermediate, and distal rings, such that the access port is formed as a single construct.

12. 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 extending through the proximal, intermediate, and distal rings; and

a seal anchor having a proximal end, a distal end, and an intermediate portion extending between the proximal and distal ends, the seal anchor adapted to be at least partially disposed in the access port;

positioning the intermediate ring of the access port into the internal body cavity;

rolling the proximal ring such that the proximal ring engages an outer epidermal tissue and the intermediate ring engages an internal peritoneal wall of tissue; and

positioning at least a portion of the seal anchor within the access port such that the distal ring engages the intermediate portion of the seal anchor in a seal relation therewith.

13. The method of accessing the internal body cavity according to claim 12, wherein rolling the proximal ring includes rolling the proximal ring having a non-circular cross-section.

14. The method of accessing the internal body cavity according to claim 13, wherein rolling the proximal ring includes rolling the proximal ring having a kidney-shaped cross-section.

15. The method of accessing the internal body cavity according to claim 12, further comprising insufflating the internal body cavity.

16. The method of accessing the internal body cavity according to claim 12, further comprising introducing a surgical instrument into the internal body cavity through the seal anchor.
