Abstract

A closure assembly includes an insertion sheath insertable into a tissue puncture and a tissue puncture closure device insertable through the insertion sheath and into the tissue puncture. The tissue puncture closure device includes a dual lumen delivery tube, a first sealing sleeve, and a second sealing sleeve. The dual lumen delivery tube has a first lumen configured to deliver a volume of sealing material to the tissue puncture, and a second lumen sized for insertion of a balloon location device. The first sealing sleeve is positioned between an outer surface of the dual lumen delivery tube and an inner surface of the insertion sheath to limit backflow of the sealing material into the insertion sheath. The second sealing sleeve is positioned between an outer surface of the balloon location device and an inner surface of the second lumen to limit backflow of the sealing material into the second lumen.

First claim

What is claimed is:

1. A closure assembly, comprising:
an insertion sheath insertable into a tissue puncture, the insertion sheath having a sidewall and a distal end;
at least one location port defined in the sidewall at the distal end of the insertion sheath;
a tissue puncture closure device insertable through the insertion sheath and into the tissue puncture, the tissue puncture closure device comprising:
a dual lumen delivery tube having a first lumen configured to deliver a volume of sealing material to the tissue puncture, and a second lumen sized for insertion of a balloon location device;
a first sealing sleeve, the first sealing sleeve being positioned between an outer surface of the dual lumen delivery tube and an inner surface of the insertion sheath to limit backflow of the sealing material into the insertion sheath, the first sealing sleeve blocking the at least one location port at the distal end of the insertion sheath, the first sealing sleeve contacting the inner surface of the insertion sheath at a plurality of spaced apart locations around a circumference of the inner surface, wherein there is no contact between the first sealing sleeve and the inner surface of the insertion sheath between each of the plurality of spaced apart locations;
a second sealing sleeve, the second sealing sleeve being connected to an outer surface of the balloon location device and positioned between the outer surface of the balloon location device and an inner surface of the second lumen to limit back flow of the sealing material into the second lumen, the second sealing sleeve being configured to seal the inner surface of the second lumen of the delivery tube during depositing of the sealing material via the first lumen.

2. The closure assembly of claim 1 , wherein the first sealing sleeve is connected to the outer surface of the dual lumen delivery tube.

3. The closure assembly of claim 1 , wherein the second sealing sleeve is connected to the outer surface of the balloon location device.

4. The closure assembly of claim 1 , wherein the first and second sealing sleeves comprise a continuous loop of compliant material.

5. The closure assembly of claim 1 , wherein the first and second sealing sleeves have a tubular construction with a circular cross section.

6. The closure assembly of claim 1 , wherein the first sealing sleeve has an oval shaped outer perimeter and a circular shaped inner perimeter.

7. The closure assembly of claim 1 , wherein the first sealing sleeve is connected to the dual lumen delivery tube with an adhesive.

8. The closure assembly of claim 1 , wherein the first sealing sleeve is connected to the dual lumen delivery tube with a heat weld.

9. The closure assembly of claim 1 , further comprising an inflation balloon positioned at a distal end of the balloon location device, the second sealing sleeve being positioned proximal of the inflation balloon.

10. The closure assembly of claim 1 , wherein the first sealing sleeve is connected to the inner surface of the insertion sheath.

11. A tissue puncture closure device, comprising:
a balloon location device having an inflation balloon positioned at a distal end portion thereof;
an insertion sheath having a distal end and at least one location port positioned laterally through the distal end;
a delivery tube having a first lumen configured to deliver a volume of sealant and a second lumen sized to receive the balloon location device, a distal end of the delivery tube being insertable through the insertion sheath to a tissue puncture;
a first sealing sleeve positioned between an outer surface of the delivery tube and an inner surface of the insertion sheath to limit backflow of the volume of sealant into the insertion sheath, the first sealing sleeve covering the at least one location port at the distal end of the insertion sheath, the first sealing sleeve contacting the inner surface of the insertion sheath at a plurality of spaced apart locations around a circumference of the inner surface, wherein there is an absence of contact between the first sealing sleeve and the inner surface of the insertion sheath between each of the plurality of spaced apart locations;
a second sealing sleeve connected to an outer surface of the balloon location device and positioned between the outer surface of the balloon location device and an inner surface of the second lumen, the second sealing sleeve being configured to limit backflow of the volume of sealant into the second lumen during depositing of the volume of sealant via the first lumen.

12. The tissue puncture closure device of claim 11 , wherein the first and second sealing sleeves are continuous tubular-shaped structures.

13. The tissue puncture closure device of claim 11 , wherein the first and second sealing sleeves comprise compliant material.

14. The tissue puncture closure device of claim 11 , wherein at least one of the first and second sealing sleeves has a circular inner cross-sectional shape and a non-circular outer cross-sectional shape.

15. The tissue puncture closure device of claim 11 , wherein the first sealing sleeve is connected to the delivery tube and the second sealing sleeve is connected to the balloon location device.
