A vascular closure assembly includes a suture placement device and a sealant delivery device. The suture placement device is operable to position at least one suture across the puncture to form a primary seal of the puncture. The sealant delivery device includes a sealant delivery tube having a first lumen sized to receive the at least one suture, and a second lumen configured to deliver a volume of sealant to the puncture after forming the primary seal to create a secondary seal of the puncture. The sealant delivery device is slidable along the at least one suture to the puncture.

1. A vascular closure assembly configured to seal a puncture in a vessel, comprising: a suture placement device operable to position at least one suture across the puncture to form a primary seal of the puncture;a sealant delivery device comprising a sealant delivery tube having a first lumen sized
1. A vascular closure assembly configured to seal a puncture in a vessel, comprising: a suture placement device operable to position at least one suture across the puncture to form a primary seal of the puncture;a sealant delivery device comprising a sealant delivery tube having a first lumen sized to receive the at least one suture, the sealant delivery device being slidable along the at least one suture to the puncture, and a second lumen configured to deliver a volume of sealant to the puncture after forming the primary seal to create a secondary seal of the puncture, wherein the sealant delivery tube comprises a helical shaped suture insertion slot at the distal end thereof. 2. The vascular closure assembly of claim 1, wherein the sealant delivery tube comprises a suture insertion slot at a distal end of the sealant delivery tube. 3. The vascular closure assembly of claim 1, wherein the sealant delivery tube comprises: a longitudinal guide slot open to the helical shaped suture insertion slot. 4. The vascular closure assembly of claim 1, wherein the sealant delivery tube comprises the helical shaped suture insertion slot at a distal end thereof, the insertion slot forms an acute angle. 5. The vascular closure assembly of claim 1, wherein the sealant delivery device comprises a suture retaining member positioned at a distal end thereof, the suture retaining member configured to permit one-way insertion of the at least one suture into the first lumen. 6. The vascular closure assembly of claim 1, wherein the suture placement device positions the at least one suture on opposite sides of the puncture, and tension is retained in the at least one suture with one of a knot and a suture locking device to at least partially seal the puncture prior to delivering the volume of sealant. 7. A method of closing a puncture in a vessel, comprising: providing a suture placement device and a sealant delivery device;positioning at least one suture across the puncture with the suture placement device;sealing the puncture with the at least one suture;advancing the sealant delivery device along the at least one suture to the puncture;delivering a volume of sealant through the sealant delivery device to the puncture to further seal the puncture, wherein the sealant delivery device comprises a helical shaped suture insertion slot at the distal end thereof. 8. The method of claim 7, further comprising providing a releasable connection between the sealant delivery device and the at least one suture. 9. The method of claim 7, wherein delivering a volume of sealant includes mixing the volume of sealant in the sealant delivery device during delivery. 10. The method of claim 7, wherein the sealant delivery device comprises a first lumen configured to receive the at least one suture and a second lumen configured to deliver the volume of sealant. 11. The method of claim 7, wherein sealing the puncture comprises advancing a knot along the at least one suture to the puncture. 12. The method of claim 7, wherein the at least one suture comprises two suture portions and the sealant delivery device is advanced along both suture portions to the puncture. 13. The method of claim 7, wherein the sealant delivery device comprises a sealant shaft and the helical shaped suture insertion slot extending proximally from an open distal end of the sealant shaft, the method comprising inserting the at least one suture into the insertion slot prior to advancing the sealant delivery device. 14. The method of claim 13, wherein the sealant delivery device comprises a guide slot spaced proximal of the open distal end and intersecting with the helical shaped suture insertion slot, the method comprising inserting the at least one suture through the insertion slot and into the guide slot prior to advancing the sealant delivery device. 15. The method of claim 7, further comprising inserting the at least one suture into a portion of the sealant delivery device before advancing the sealant delivery device. 16. A method of sealing a puncture in a vessel accessible through a percutaneous incision, the method comprising: providing a sealant delivery device having first and second lumens, and a suture placement device;positioning at least one suture across the puncture with the suture placement device;advancing a knot along the at least one suture to seal the puncture;positioning the at least one suture in the first lumen;advancing the sealant delivery device along the at least one suture to the puncture;delivering a volume of sealant through the second lumen to the puncture to seal the puncture, wherein the sealant delivery device comprises a helical shaped suture insertion slot at the distal end thereof. 17. The method of claim 16, the helical shaped suture insertion slot providing lateral access into the first lumen, and positioning the at least one suture in the first lumen includes laterally inserting the at least one suture through the helical shaped suture insertion slot. 18. The method of claim 17, wherein the sealant delivery device includes a guide slot intersecting the helical shaped suture insertion slot and extending longitudinally, and positioning the at least one suture in the first lumen includes positioning the at least one suture in the guide slot. 19. The method of claim 16, wherein the sealant comprises a resorbable bioadhesive. 20. The method of claim 16, wherein positioning at least one suture across the puncture with the suture placement device includes inserting the suture placement device in the puncture, advancing at least one needle through a wall of the vessel adjacent to the puncture, drawing the at least one suture through the wall of the vessel, and removing the suture placement device from the puncture.
