Device and method for sealing puncture wounds
First Claim
1. A device for inserting hemostatic material inward through a tissue channel until it is disposed by an outside wall of a blood vessel of a patient, said blood vessel wall having a puncture having a predetermined width therein adjacent said tissue channel, said tissue channel and said puncture having been formed by an original procedure sheath, comprising:
- (a) a charge of hemostatic material having a width greater than said predetermined width of said puncture, such that the material cannot enter the blood vessel,(b) a hollow insertion sheath adapted to pass through said tissue channel and having an inner diameter, said inner diameter of said insertion sheath being larger than said predetermined width of said puncture whereby said charge of hemostatic material can slidably engage said inner diameter of said hollow insertion sheath,(c) means for placing said hemostatic material in said hollow insertion sheath, and(d) means for advancing said hemostatic material through said hollow insertion sheath inward to the outside of said vessel wall around said puncture,whereby said charge of hemostatic material cannot enter said blood vessel through said puncture.

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.

7. A device for use in sealing a puncture having a predetermined width in a wall of a blood vessel of a patient where said blood vessel is separated from the skin of the patient by a layer of tissue, where a tissue channel communicates between said puncture and the patient'"'"'s skin, said tissue channel and said puncture having been formed by an original procedure sheath, comprising:
-
(a) an elongated hollow insertion sheath having a distal end, a proximal end, and an inner diameter, said inner diameter of said hollow insertion sheath being larger than said predetermined width of said puncture, (b) hemostatic material, having a width greater than said predetermined width of said puncture such that the material cannot enter the blood vessel, whereby said hemostatic material can slidably engage said inner diameter of said hollow insertion sheath, (c) means for inserting said hemostatic material into said insertion sheath, and (d) means for advancing said hemostatic material through said insertion sheath, out of the distal end thereof and inward until it is disposed by said vessel wall by said puncture, whereby said charge of hemostatic material cannot enter said blood vessel through said puncture. - View Dependent Claims (8, 9, 10, 11, 12)
