Abstract
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.

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.
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.
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.
