Abstract

An access closure device for closing an opening in tissue is provided. The access closure device may comprise an implant delivery system and a sealant delivery mechanism. The implant delivery system may comprise a suture, a procedural sheath, a delivery tube, an deployable implant and a suture attached to the implant. The sealant delivery mechanism may comprise a sealant deliverable over a suture through the procedural sheath, configured to settle proximal an implant located in an access track.

First claim

What is claimed is:

1 . An access closure system comprising:
a hemostasis device with a predeployment insertion profile; a procedural sheath configured to extend into a body lumen through an access track; and an elongate ejection member configured to eject the hemostasis device into the body lumen.

2 . The access closure system of claim 1 , wherein the hemostasis device is an implant with an attached suture, the implant and attached suture being disposed within the procedural sheath.

3 . The access closure system of claim 2 , further comprising a dilator configured to extend through the procedural sheath, wherein a distal end of the dilator extends distally past a distal end of the procedural sheath.

4 . The dilator of claim 3 , further comprising a marker port proximate the distal end of the dilator extending through at least a portion of a thickness of the dilator and connecting to an inner marker lumen of the dilator.

5 . The dilator of claim 4 , wherein the inner marker lumen extends proximally along a length of the dilator to an aperture that extends through a portion of the thickness of the dilator.

6 . The dilator of claim 4 , wherein the marker port, aperture, and inner marker lumen are configured to provide a pulsatile mark defining a flow of blood external to the body lumen.

7 . The access closure system of claim 3 , wherein the dilator is configured to dilate a size of at least a portion of the procedural sheath.

8 . The access closure system of claim 2 , wherein the implant is configured as a deployable foot.

9 . The access closure system of claim 2 , wherein the implant comprises one or a combination of polyglycolic acid, a poly(L-lactic acid), polycaprolactone, poly(D, L-lactic acid), Poly(trimethylene carbonate), or poly(p-dioxanone).

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

11 . The access closure system of claim 10 , 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.

12 . The access closure system of claim 10 , wherein the sealant is provided as a solid structure comprising one or a combination of crosslinked polyethylene glycol, polyethylene oxide, hyaluronic acid, gelatin, or collagen.

13 . The access closure system of claim 10 , wherein the sealant absorbs fluid and swells to seal the access track and effect hemostasis.

14 . The access closure system of claim 1 , wherein the procedural sheath comprises one or more indicia on an external surface of the procedural sheath.

15 . A method for closing an opening in a vessel wall and an access track, the method comprising:
positioning a procedural sheath through the access track and into a body lumen; positioning an implant in the body lumen; retracting the implant to position a first portion of the implant within the body lumen and a second portion of the implant within the access track; and fully retracting the procedural sheath outwardly from the body lumen through the access track until a portion of the implant is substantially flush with the vessel wall.

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

17 . The method for closing the opening in the vessel wall and the access track of claim 16 , the method further comprising:
advancing a dilator distally through the procedural sheath; dilating the procedural sheath; inserting a delivery tube into the procedural sheath; and detaching the implant from the sheath.

18 . The method for closing the opening in the vessel wall and the access track of claim 17 , the method further comprising:
removing the procedural sheath and a delivery tube from the access track; advancing at least one sealing component into the access track; and cutting and sealing the at least one suture in the access track.
