Abstract

An access closure device for closing an opening in tissue is provided. The access closure device may comprise a balloon delivery system and a sealant delivery system. The balloon delivery system may comprise a suture, a delivery shaft, an inflatable balloon, and a balloon segment releasably attached to the delivery shaft. The sealant delivery system may comprise a sealant delivery shaft, an ejection tube, and a snare wire configured to snare a suture of the delivery system.

First claim

What is claimed is:

1 . An access closure device comprising:
a balloon delivery system comprising:
a balloon;
a balloon segment supporting the balloon, the balloon segment having a lumen and a plurality of openings in fluid communication with an interior of the balloon and the lumen;
at least one valve selectively sealing the lumen of the balloon segment; and
an attachment portion proximate the at least one valve, the attachment portion configured to releasably couple the balloon segment to a portion of the balloon delivery system.

2 . The access closure device of claim 1 , wherein the balloon delivery system comprises a delivery shaft configured to releasably couple to the attachment portion of the balloon segment.

3 . The access closure device of claim 2 , wherein the delivery shaft comprises at least one weeping port proximate the balloon segment and in fluid communication with a corresponding check valve.

4 . The access closure device of claim 3 , wherein the at least one weeping port is configured to open upon the balloon exceeding a predetermined pressure threshold, the at least one weeping port opening to an exterior of the delivery shaft.

5 . The access closure device of claim 2 , wherein the balloon delivery system is provided with an integrated delivery shaft.

6 . The access closure device of claim 1 , wherein the balloon and the balloon segment comprise a bioabsorbable, biodegradable, or bioresorbable material.

7 . The access closure device of claim 1 , further comprising a sealant delivery system comprising a sealant delivery shaft configured to deliver a sealant to an access track.

8 . The access closure device of claim 7 , wherein the sealant delivery shaft defines a lumen and corresponding ejection shaft, the ejection shaft slidingly engaged with the lumen of the sealant delivery shaft.

9 . The access closure device of claim 7 , wherein the sealant is provided as a liquid sealing solution comprising one or a combination of polyethylene glycol, polyethylene oxide, hyaluronic acid, gelatin, or collagen.

10 . The access closure device of claim 9 , wherein the liquid sealing solution is a two-part system premixed prior to administration through the sealant delivery system.

11 . The access closure device of claim 10 , wherein the liquid sealing solution comprises at least one gelling or cross-linking mechanism.

12 . The access closure device of claim 7 , wherein the sealant is provided as a solid structure comprising crosslinked polyethylene glycol, polyethylene oxide, hyaluronic acid, gelatin, or collagen.

13 . The access closure device of claim 2 , wherein the delivery shaft defines at least one indicium on an outer surface of the delivery shaft.

14 . The access closure device of claim 2 , wherein a syringe is in fluid communication with the lumen of the delivery shaft.

15 . A method for closing an access track, the method comprising the steps of:
providing a procedural sheath through the access track in a body lumen; advancing a balloon delivery system comprising a balloon and a balloon segment releasably attached to a delivery shaft into a lumen of the procedural sheath and into the body lumen; partially inflating the balloon of the balloon delivery system; retracting the balloon delivery system until the balloon is in contact with a distal tip of the procedural shaft; and retracting the balloon delivery system and the procedural sheath outwardly from the body lumen through the access track until the balloon contacts an inner wall of the body lumen such that resistance to further retraction is generated.

16 . The method for closing an access track of claim 15 , the method further comprising the steps of:
retracting the procedural sheath a distance to align with at least one indicium defined on an outer surface of the delivery shaft; and tensioning at least one suture, the suture connected to the balloon and/or the balloon segment, such that the balloon is retracted a distance into the access track.

17 . The method for closing an access track of claim 16 , the method further comprising the steps of:
advancing a bypass tube distally on the delivery shaft; fully inflating the balloon; and detaching the balloon and the balloon segment from the balloon delivery system.

18 . The method for closing an access track of claim 16 , the method further comprising the steps of:
removing the procedural sheath and the delivery system from the access track; snaring the at least one suture using a snare wire of a sealant delivery system; advancing at least one sealing component into the access track; cutting and sealing the at least one suture in the access track; attaching the at least one suture to a skin surface using a cover.
