Abstract

A closure device operable to seal a vessel puncture and including a delivery member and a sealant material applicator. The delivery member is insertable through a tissue tract to the vessel puncture. The sealant material applicator is configured to supply a volume of sealant material to the delivery member and includes a housing, a plunger assembly, and at least one container. The housing includes at least first and second chambers, wherein the first chamber carries a first sealant component and the second chamber carries a second sealant component. The container is insertable into the first or second chamber and carries a third sealant component of the sealant material. The sealant material applicator creates flow communication between the container and at least one of the first and second chambers to mix the third sealant component with the first and second sealant components.

First claim

What is claimed is:

1. A closure device operable to seal a vessel puncture, comprising:
a delivery member insertable through a tissue tract to the vessel puncture;
a sealant material applicator configured to supply a volume of sealant material to the delivery member, the sealant material applicator comprising:
a housing having at least first and second chambers, the delivery member being in fluid communication with the first and second chambers, the first chamber carrying a first sealant component of the sealant material and the second chamber carrying a second sealant component of the sealant material;
a plunger assembly having at least first and second plunger members insertable into the first and second chambers, respectively;
at least one container positioned in the first or second chamber, the at least one container carrying a third sealant component of the sealant material;
wherein the sealant material applicator is operable to create flow communication between the at least one container and at least one of the first and second chambers to mix the third sealant component with at least one of the first and second sealant components prior to creating the volume of sealant material.

2. The closure device of claim 1 , wherein the sealant material applicator is operable to deliver the volume of sealant material through the delivery member and to the tissue tract to seal the vessel puncture from outside the vessel.

3. The closure device of claim 1 , wherein the sealant material applicator includes a mixing chamber at a distal end thereof, the first, second and third sealant components being at least partially mixed in the mixing chamber before being ejected from the sealant material applicator as the sealant material.

4. The closure device of claim 1 , wherein the at least one container is positioned within the first chamber and exposed to the first sealant component, and operating the sealant material applicator ruptures the at least one container to create flow communication between the at least one container and the first chamber.

5. The closure device of claim 1 , wherein the first sealant component is carried in a first container, the first container being positioned in the first chamber, the second sealant component is carried in a second container, the second container being positioned in the second chamber, and the at least one container comprises a third container carrying the third sealant component, the third container being positioned in the first or second chamber.

6. The closure device of claim 5 , wherein operating plunger assembly creates flow communication between the third container and the first container to combine the first and third sealant components prior to ejecting the volume of sealant material to the delivery member.

7. The closure device of claim 5 , wherein the first, second and third sealant components are mixed within a mixing chamber of the sealant material applicator prior to being ejected from the sealant material applicator.

8. The closure device of claim 5 , wherein the sealant material applicator includes at least one needle configured to create the flow communication.

9. The closure device of claim 5 , wherein at least one of the first, second and third containers includes a frangible seal.
