Abstract

A surgical access device comprises a conduit comprising a proximal portion and a distal portion. An inflatable member at least partially surrounds a portion of the conduit and is positioned proximate to the distal portion of the conduit. In various embodiments, a protective sleeve can at least partially surround a portion of the conduit and is movable between at least a first position and a second position. In at least one embodiment, the protective sleeve is configured to at least partially cover the inflatable member when in the first position and is configured to expose the inflatable member when in the second position.

Claims

1. A surgical access device, comprising:

a conduit comprising a proximal end and a distal end;

an inflatable member at least partially surrounding a portion of the conduit and positioned proximate to the distal end of the conduit; and

a protective sleeve at least partially surrounding a portion of the conduit, the protective sleeve configured to be moved at least between a first position and a second position, the protective sleeve configured to at least partially cover the inflatable member when in the first position and configured to expose the inflatable member when in the second position.

2. The surgical access device of claim 1, the protective sleeve configured to cover the inflatable member when the protective sleeve is in the first position.

3. The surgical access device of claim 1, comprising a handle device one of attached to and integrally formed with the protective sleeve and positioned near a proximal end of the protective sleeve.

4. The surgical access device of claim 1, the protective sleeve comprised of a low-friction material configured to enable sliding over at least a portion of the inflatable member when moving between the first position and the second position.

5. The surgical access device of claim 1, wherein at least a portion of the conduit and at least a portion of the protective sleeve comprise a flexible material.

6. The surgical access device of claim 1, the protective sleeve comprising an outer perimeter sized to be introduced into a working channel of an endoscope.

7. The surgical access device of claim 1, the conduit configured to receive therethrough at least one of a rotary needle, a veress needle, a cutting member, a puncturing member, a piercing member, and a guide wire.

8. The surgical access device of claim 1, the protective sleeve configured to shield the inflatable member and at least inhibit tearing or puncturing of the inflatable member prior to inflation when the protective sleeve is in the first position.

9. The surgical access device of claim 1, the protective sleeve configured to shield the inflatable member and at least inhibit tearing, puncturing or unpleating of the inflatable member during entry into, traveling within, or exiting from a working channel of an endoscope when the protective sleeve is in the first position.

10. The surgical access device of claim 1, the protective sleeve comprising an elongate passage comprising an inner perimeter sized to at least inhibit the inflatable member from inflating under subatmospheric pressure conditions when the protective sleeve is in the first position.

11. The surgical access device of claim 1, the conduit comprising a first outer perimeter, the inflatable member, in an uninflated state, comprising a second outer perimeter, wherein the second outer perimeter is larger than the first outer perimeter, the protective sleeve comprising an elongate channel comprising an inner perimeter, wherein the inner perimeter is larger than the second outer perimeter.

12. The surgical access device of claim 1, the inflatable member comprising at least two longitudinally oriented pleats positioned about the perimeter of the inflatable member, wherein the protective sleeve is configured to at least minimize unpleating of the pleats of the inflatable member when in the first position.

13. A method of claim 1, comprising:

inserting the surgical access device of claim 1 into a natural orifice of a patient with the protective sleeve in the first position; and

retracting the protective sleeve into the second position.

14. A surgical access device, comprising:

a conduit comprising a proximal end and a distal end;

an inflatable member at least partially surrounding a portion of the conduit and positioned proximate to the distal end of the conduit; and

a protective sleeve at least partially surrounding a portion of the conduit, the protective sleeve moveable at least between a first position, where the protective sleeve at least partially covers the inflatable member, and a second position, where the inflatable member is exposed, the protective sleeve comprising an elongate channel comprising an inner perimeter sized to at least inhibit the inflatable member from inflating under subatmospheric pressure conditions when the protective sleeve is in the first position.

15. The surgical access device of claim 14, the protective sleeve configured to cover the inflatable member when the protective sleeve is in the first position.

16. The surgical access device of claim 14, comprising a handle device one of attached to and integrally formed with the protective sleeve and positioned near a proximal end of the protective sleeve, the handle device configured to be used to move the protective sleeve between the first position and the second position.

17. The surgical access device of claim 14, the protective sleeve configured to shield the inflatable member and at least inhibit tearing, puncturing, or unpleating of the inflatable member prior to inflation when the protective sleeve is in the first position.

18. The surgical access device of claim 14, the conduit comprising a first outer perimeter, the inflatable member, in an uninflated state, comprising a second outer perimeter, wherein the second outer perimeter is larger than the first outer perimeter, the protective sleeve comprising an elongate channel comprising an inner perimeter, wherein the inner perimeter is larger than the second outer perimeter.

19. A surgical access device, comprising:

a conduit comprising a proximal portion and a distal portion, wherein the conduit is configured to receive a needle;

an inflatable member at least partially surrounding a portion of the conduit and positioned proximate to the distal portion of the conduit, the inflatable member comprising an outer perimeter in an at least partially uninflated state; and

a sleeve at least partially surrounding a portion of the conduit, the sleeve comprising an elongate channel comprising an inner perimeter larger than the outer perimeter, the sleeve moveable at least between a first position and a second position, the sleeve configured to shield the inflatable member and inhibit tearing or puncturing of the inflatable member when the sleeve is in the first position, and the sleeve configured to expose the inflatable member for inflation when the sleeve is in the second position.

20. The surgical access device of claim 19, the sleeve configured to cover the inflatable member when the sleeve is in the first position to at least inhibit the inflatable member from inflating under subatmospheric pressure conditions.
