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 transitionable to a plurality of states, each state corresponding to a different length of the seal anchor member along the longitudinal axis, the first end including an inner portion and a folded portion folded over the inner portion, the inner portion and the folded portion defining a slot extending along the longitudinal axis of the seal anchor member; and

a guide pin secured with the folded portion, the guide pin slidably engaging the slot defined in the inner portion to transition the first end to one of the plurality of states.

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

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

4. The surgical apparatus according to claim 2, wherein the plurality of folded states include a minimum folded state corresponding 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 7, wherein the first end further defines an aperture configured to receive the guide pin disposed through the aperture and the slot to facilitate transition within the plurality of folded states.

9. 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.

10. 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.

11. 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.

12. The surgical apparatus according to claim 11, further comprising a plurality of longitudinal ports.

13. The surgical apparatus according to claim 1, wherein the folded portion defines a bore configured to receive the guide pin therethrough.

14. The surgical apparatus according to claim 1, wherein at least a portion of the slot defined in the inner portion is in a superposed relation with the slot defined in the folded portion.

15. The surgical apparatus according to claim 1, wherein the slot defines a length along the longitudinal axis.
