Abstract
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 Analysis
Total Claims: 18
Claim 1
Independent Claim
209 words
A device 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 having a predetermined width therein adjacent the tissue channel, the tissue channel and the 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 the puncture such that said charge of hemostatic material cannot enter the blood vessel through the puncture, (b) a hollow insertion sheath adapted to pass through the tissue channel and having an inner diameter, said inner diameter of said insertion sheath being larger than said predetermined width of the puncture whereby said charge of hemostatic material is slidable within said inner diameter of said hollow insertion sheath, (c) means for placing said hemostatic material in said hollow insertion sheath, and (d) a tissue dilator having a size substantially corresponding to said width of said charge of hemostatic material for slidably engaging said inner diameter of said hollow insertion sheath and for advancing said hemostatic material through said hollow insertion sheath to the outside of the vessel wall around the puncture without ever actually entering the lumen of the blood vessel.
Claim 2
Independent Claim
209 words
A device 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 having a predetermined width therein adjacent the tissue channel, the tissue channel and the 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 the puncture such that said charge of hemostatic material cannot enter the blood vessel through the puncture, (b) a hollow insertion sheath adapted to pass through the tissue channel and having an inner diameter, said inner diameter of said insertion sheath being larger than said predetermined width of the puncture whereby said charge of hemostatic material is slidable within said inner diameter of said hollow insertion sheath, (c) means for placing said hemostatic material in said hollow insertion sheath, and (d) a tissue dilator having a size substantially corresponding to said width of said charge of hemostatic material for slidably engaging said inner diameter of said hollow insertion sheath and for advancing said hemostatic material through said hollow insertion sheath to the outside of the vessel wall around the puncture without ever actually entering the lumen of the blood vessel.

Claim 13
Independent Claim
281 words
A device for use in sealing a puncture having a predetermined width in a wall of a blood vessel of a patient where the blood vessel is separated from the skin of the patient by a layer of tissue, where a tissue channel communicates between the puncture and the patient's skin and where a guide wire having proximal and distal ends extends at least from the puncture, through the channel, to the patient's skin, the tissue channel and the puncture having been formed by an original procedure sheath, comprising (a) a tissue dilator having a front portion and a rear portion, (b) a dilator channel running through said tissue dilator from said front portion to said rear portion, said dilator channel being adapted to receive therein and pass therethrough the proximal end of said guide wire, (c) 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 the puncture, (d) hemostatic material having a width greater than said predetermined width of the puncture, whereby said hemostatic material is slidable within said inner diameter of said hollow insertion sheath, and said hemostatic material cannot enter the blood vessel through the puncture, and (e) means for inserting said hemostatic material into said hollow insertion sheath, said tissue dilator having a size substantially corresponding to said width of said hemostatic material for slidably engaging said inner diameter of said hollow insertion sheath and for advancing said hemostatic material through said hollow insertion sheath to the outside of the vessel wall around the puncture without ever actually entering the lumen of the blood vessel.
Claim 14
Independent Claim
281 words
A device for use in sealing a puncture having a predetermined width in a wall of a blood vessel of a patient where the blood vessel is separated from the skin of the patient by a layer of tissue, where a tissue channel communicates between the puncture and the patient's skin and where a guide wire having proximal and distal ends extends at least from the puncture, through the channel, to the patient's skin, the tissue channel and the puncture having been formed by an original procedure sheath, comprising (a) a tissue dilator having a front portion and a rear portion, (b) a dilator channel running through said tissue dilator from said front portion to said rear portion, said dilator channel being adapted to receive therein and pass therethrough the proximal end of said guide wire, (c) 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 the puncture, (d) hemostatic material having a width greater than said predetermined width of the puncture, whereby said hemostatic material is slidable within said inner diameter of said hollow insertion sheath, and said hemostatic material cannot enter the blood vessel through the puncture, and (e) means for inserting said hemostatic material into said hollow insertion sheath, said tissue dilator having a size substantially corresponding to said width of said hemostatic material for slidably engaging said inner diameter of said hollow insertion sheath and for advancing said hemostatic material through said hollow insertion sheath to the outside of the vessel wall around the puncture without ever actually entering the lumen of the blood vessel.
