Surgical access device
First Claim
1. A surgical access device sized to fit in a working channel of an endoscope and configured to be advanced through a tissue opening to a surgical site, 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 and configured to translate within the working channel of the endoscope, 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, the protective sleeve configured to be in the first position when the inflatable member is advanced through the tissue opening to the surgical site.

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.

13. A surgical access device sized to fit in a working channel of an endoscope and configured to be passed through punctured tissue to gain access to a surgical site, comprising:
-
a conduit comprising a proximal end and a distal end; a needle within the conduit, the needle configured to puncture tissue; 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 and configured to translate within the working channel of the endoscope, 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 configured to be in the first position when the inflatable member is passed through the punctured tissue to the surgical site, 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. - View Dependent Claims (14, 15, 16, 17)

18. A surgical access device sized to fit in a working channel of an endoscope and configured to be advanced through a tissue opening, 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 and configured to translate within the working channel of the endoscope, 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, the protective sleeve configured to be in the first position when the inflatable member is advanced through the tissue opening. - View Dependent Claims (19)
