Abstract

A device is proposed for inserting hemostatic material through a tissue channel and against the outside wall of a blood vessel of a patient, wherein the blood vessel wall has a puncture therein adjacent the tissue channel. The device includes a charge of hemostatic material and a hollow sheath adapted to pass through the tissue channel, the sheath having a cross sectional profile larger than the puncture. The device places the hemostatic material in the hollow sheath and advances the hemostatic material through the sheath to the outside of the vessel wall around the puncture.

Claims

1. A plug member for sealing an incision formed in the body of a patient wherein the incision extends from the skin of the patient through the wall of a blood vessel and into the lumen of the blood vessel of the patient, comprising

an elongate body having distal and proximal end portions, said body being formed from a bioabsorbable material in the form of a mass of loose fibers oriented randomly with respect to one another.

2. The plug member as claimed in claim 1, wherein said bioabsorbable material includes a hemostatic material.

3. The plug member as claimed in claim 2, wherein said hemostatic material consists essentially of collagen.

4. A plug member for sealing an incision formed in the body of a patient wherein the incision extends from the skin of the patient through the wall of a blood vessel and into the lumen of the blood vessel of the patient, comprising

an elongate body having distal and proximal end portions, said body being formed from a bioabsorbable material in the form of a mass having loose fibers oriented randomly with respect to one another at one of said end portions and more densely packed fibers at another of said end portions.

5. The plug member as claimed in claim 4, wherein said bioabsorbable material includes a hemostatic material.

6. The plug member as claimed in claim 5, wherein said hemostatic material consists essentially of collagen.

7. A plug member for sealing an incision formed in the body of a patient wherein the incision extends from the skin of the patient through the wall of a blood vessel and into the lumen of the blood vessel of the patient, comprising

an elongate body having distal and proximal end portions, said body being formed from a bioabsorbable material in the form of a mass of a densely packed material and having a membrane of a hemostatic material disposed on one of said end portions.

8. The plug member as claimed in claim 7, wherein said bioabsorbable material includes a hemostatic material.

9. The plug member as claimed in claim 8, wherein said bioabsorbable material consists essentially of collagen.
