ACCESS DEVICE FOR BODY TISSUE AND METHOD OF USING SAME
First Claim
1. An apparatus for selectively permitting access through a body tissue, the body tissue having oppositely disposed first and second tissue sides with an aperture extending therebetween, the apparatus comprising:
- a proximal balloon adapted for placement adjacent the first tissue side;
a distal balloon adapted for placement adjacent the second tissue side;
an expandable support member adapted to extend through the aperture and defining a support member lumen providing fluid communication between the first and second tissue sides, the expandable support member being attached to the proximal and distal balloons and having at least one of an inner support member lining and an outer support member cover;
a support member valve located within the support member lumen and selectively permitting access through the aperture between the first and second tissue sides; and
a closure device for permanently occluding the support member lumen.

Abstract
A body tissue has oppositely disposed first and second tissue sides with an aperture extending therebetween. An apparatus for selectively permitting access through the body tissue includes a proximal balloon adapted for placement adjacent the first tissue side. A distal balloon is adapted for placement adjacent the second tissue side. An expandable support member is adapted to extend through the aperture and defines a support member lumen providing fluid communication between the first and second tissue sides. The expandable support member is attached to the proximal and distal balloons and has at least one of an inner support member lining and an outer support member cover. A support member valve is located within the support member lumen and selectively permits access through the aperture between the first and second tissue sides. A closure device is provided for permanently occluding the support member lumen.

20. An access device for a body tissue, the body tissue having oppositely disposed first and second tissue sides with an aperture extending therebetween, the access device comprising:
-
means for defining a lumen through the aperture; means for padding the means for defining, the means for padding being at least partially located in contact with both the means for defining and the aperture; means for retaining the means for defining within the aperture, the means for retaining being inflatable; means for selectively permitting fluid communication through the lumen between the first and second tissue sides; and means for permanently occluding the lumen. - View Dependent Claims (21, 22, 23)

24. A method of performing a surgical procedure through a body tissue, the body tissue having oppositely disposed first and second tissue sides with an aperture extending therebetween, the method comprising the steps of:
-
providing an expandable support member, having a support member lumen, with at least one of an outer support member cover and an inner support member lining; extending the expandable support member through the aperture; providing fluid communication between the first and second tissue sides through the support member lumen; inflating a proximal balloon adjacent the first tissue side, the proximal balloon being attached to a first end of the expandable support member; inflating a distal balloon adjacent the second tissue side, the distal balloon being attached to a second end of the expandable support member spaced apart from the first end; selectively permitting fluid communication through the support member lumen; extending at least one surgical tool through the support member lumen to conduct the surgical procedure through the aperture; removing the at least one surgical tool from the support member lumen; and permanently occluding the support member lumen. - View Dependent Claims (25, 26, 27)
