Abstract

A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus is configured to have different lengths. In one embodiment, the surgical includes a seal anchor member having two ends, and one of which is adapted to fold resulting in a plurality of folded states. Each folded state corresponds to a different length of the seal anchor member. The seal anchor member includes a slot to facilitate transition within the plurality of folded states. The seal anchor member further includes an aperture and a pin configured to further facilitate transition within the plurality of folded states.

Claims

1. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:

a seal anchor member defining a longitudinal axis and a length, the seal anchor member including a first end and a second end, the first end configured to fold along the longitudinal axis, the first end defining a plurality of states, each state corresponding to a different length of the seal anchor member.

2. The surgical apparatus according to claim 1, wherein the plurality of states comprises a plurality of folded states.

3. The surgical apparatus according to claim 2, wherein the plurality of folded states includes a maximum folded state such that the maximum folded state corresponds to a minimum length of the seal anchor member.

4. The surgical apparatus according to claim 2, wherein the plurality of folded states includes a minimum folded state such that the minimum folded state corresponds to a maximum length of the seal anchor member.

5. The surgical apparatus according to claim 2, wherein the first end has an outer surface and an inner surface in each folded state.

6. The surgical apparatus according to claim 5, wherein the outer surface and the inner surface of the first end are connected.

7. The surgical apparatus according to claim 5, wherein the outer surface and the inner surface of the first end are sutured together.

8. The surgical apparatus according to claim 2, wherein the first end defines a slot configured to facilitate transition within the plurality of folded states.

9. The surgical apparatus according to claim 7, wherein the first end further defines an aperture, and a pin disposed through the aperture and the slot to facilitate transition within the plurality of folded states.

10. The surgical apparatus according to claim 1, wherein the plurality of states comprises an unfolded state, wherein the unfolded state corresponds to a maximum length of the seal anchor member.

11. The surgical apparatus according to claim 1, wherein the first end defines a first radial dimension, the second end defines a second radial dimension, and the first radial dimension is substantially larger than the second radial dimension.

12. The surgical apparatus according to claim 1, wherein the seal anchor member defines a substantial coring configuration therein creating an open space in a center region of the seal anchor member.

13. The surgical apparatus according to claim 1, wherein the seal anchor member exhibits an hourglass configuration elongated in a radial axis of the seal anchor member.

14. The surgical apparatus according to claim 13, further comprising a plurality of longitudinal ports arranged in a linear fashion along the radial axis of the seal anchor member.

15. The surgical apparatus according to claim 1, further comprising at least one slit facilitating movement of an object inserted in the seal anchor member.

16. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:

a seal anchor member defining a longitudinal axis, a radial axis, a length, a plurality of lumen extending at least partially therethrough for receipt of a surgical object, and at least one slit positioned between the plurality of lumen, the seal anchor member including a proximal end, a distal end and an intermediate portion between the proximal and distal ends, the proximal end defining a first diameter at a proximal-most end, the distal end defining a second diameter at a distal-most end, wherein the first diameter is substantially larger than the second diameter.

17. The surgical apparatus according to claim 16 wherein the at least one slit at least partially isolates the movement of a first object inserted through a first one of the plurality of lumen from the movement of a second object inserted through a second one of the plurality of lumen.

18. The surgical apparatus according to claim 16, wherein the proximal end defines a radial diameter that develops gradually larger from the intermediate portion towards the proximal-most end.

19. The surgical apparatus according to claim 16, wherein the proximal end and the intermediate portion define a coring configuration creating an open space in a center region of the seal anchor member.

20. The surgical apparatus according to claim 16 further comprising a plurality of longitudinal ports disposed adjacent to the distal end.
