Method and apparatus for sealing access

1. A method of sealing a puncture site in a wall of a tubular tissue structure or in the wall of a body cavity of an anatomy comprising:

providing an elongated element having an outer wall and defining a lumen therein, the outer wall of the elongated element having a hole therein providing access to the lumen; and

releasably attaching a bioabsorbable member to the elongated element by inserting the bioabsorbable member into the hole in the wall of the elongated element such that a first portion of the bioabsorbable member constructed from a first bioabsorbable material is outside of the lumen and a second portion of the bioabsorbable member constructed from the first bioabsorbable material is within the lumen of the elongated element; the first portion of the bioabsorbable member including a hollow tube of bioabsorbable material, the first portion being sized and shaped to abut an exterior of the wall of the tubular tissue structure and/or body cavity to prevent entry of the first portion into the tubular tissue structure or body cavity, the second portion of the bioabsorbable member sized and shaped differently than the first portion, the second portion being flat and sized to enter the tubular tissue structure or body cavity at the puncture site;

wherein the releasable attachment of the bioabsorbable member to the elongated element provides that advancing the elongated element in the anatomy causes the second portion of the bioabsorbable member to evacuate the lumen of the elongated element and

coupling a tether to the bioabsorbable member, the tether, when pulled, being capable of causing the second portion to contract proximate the first portion.

2. The method of claim 1 , wherein the first portion of the bioabsorbable member includes a cuff portion, and the cuff is positioned on the elongated element such that advancing the elongated element in the anatomy causes the cuff to abut the anatomy and the abutment of the cuff to anatomy prevents the cuff from advancing with the elongated element and causes the second portion of the bioabsorbable member to evacuate the lumen as the elongated element is advanced.

3. The method of claim 1 , wherein releasably attaching the bioabsorbable member includes releasably attaching a tissue graft for sealing a puncture site in the wall of a tubular tissue structure or in the wall of a body cavity of an anatomy, the tissue graft comprising:

a first portion including a hollow tube of bioabsorbable material, the first portion being sized and shaped to abut an exterior of the wall of the tubular tissue structure and/or body cavity to prevent entry of the first portion into the tubular tissue structure or body cavity, and

a second portion sized and shaped differently than the first portion, the second portion being flat and sized to enter the tubular tissue structure or body cavity at the puncture site.

4. The method of claim 1 , further including obtaining a kit including:

a needle;

a guide wire;

the elongated element having an access port disposed in a wall of the elongated element, and

the bioabsorbable member including:

the first portion including a hollow tube of bioabsorbable material, and

the second portion sized and shaped differently than the first portion, the second portion passing through the access port.

5. A tissue graft for sealing a puncture site in the wall of a tubular tissue structure or in the wall of a body cavity of an anatomy, the tissue graft comprising:

a first portion including a hollow tube of bioabsorbable material, the first portion being sized and shaped to abut an exterior of the wall of the tubular tissue structure and/or body cavity to prevent entry of the first portion into the tubular tissue structure or body cavity, and

a second portion sized and shaped differently than the first portion, the second portion sized to enter the tubular tissue structure or body cavity at the puncture site, the second portion including a single layer of material having a first side and a second side opposite the first side, the first and second side sharing a plurality of edges, the second portion having a contracted configuration that provides for both the first and second side to directly abut the tubular tissue structure or body cavity at the puncture site.

6. The graft of claim 5 , wherein the second portion includes a distal end and opposing lateral sides of the single layer of material, the lateral sides being spaced apart and being defined by points at which graft material ends.

7. The graft of claim 5 , wherein the first portion has a first width and the second portion has a second width, the first width being bigger than the second width.

8. The graft of claim 5 , further including a tether therein.

9. The graft of claim 8 , wherein the tether has a first tether position that allows the graft to assume a first graft position and has a second tether position that requires the graft to assume a second graft position.

10. The graft of claim 9 , wherein the second graft position is a compressed position that causes the second portion to be closer to the first position than the first graft position.

11. The graft of claim 9 , wherein the second graft position causes the graft to have a shorter length than the first position.

12. The graft of claim 5 , wherein the graft includes submucosal tissue.

13. The graft of claim 5 , wherein the second portion consists of a single flat layer of bioabsorbable material, and at least one tether therein.

14. A kit including:

a needle;

a guide wire;

an elongated element having an access port disposed in a wall of the elongated element, and

a bioabsorbable member including:

a first portion including a hollow tube of a first bioabsorbable material, and

a second non-tubular portion of the first bioabsorbable material sized and shaped differently than the first portion, the second portion passing through the access port

wherein the second portion includes a single layer of material having a first side and a second side opposite the first side, the first and second sides sharing a plurality of edges, the second portion having a contracted configuration that provides for both the first and second side to directly abut a tubular tissue structure or a body cavity at a puncture site therein.

15. The kit of claim 14 , wherein the first portion is sized and shaped to abut an exterior of a wall of a tubular tissue structure and/or body cavity to prevent entry of the first portion into the tubular tissue structure or body cavity.

16. The kit of claim 14 , wherein the second portion is a single flat layer of bioabsorbable material.

17. The kit of claim 16 , wherein the second portion is sized to enter a tubular tissue structure or body cavity at a puncture site. submucosal tissue.
