Abstract
Abstract The present invention relates to a method for the formulation of fibrin sealant in a single delivery system. The method involves mixing a fibrinogen/Factor XIII precipitate solution with thrombin under conditions such that thrombin clotting activity is inhibited and said mixture is applied to a body site under conditions which activate the thrombin to convert fibrinogen into fibrin sealant. A single device, syringe or container, can be used to apply the fibrin sealant formulation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
50 words
An applicator for use in the preparation of a fibrin sealant comprising a container means and an outlet means operably connected thereto, said container means having disposed therewithin a solution consisting essentially of fibrinogen, Factor XIII, mature thrombin and an agent that inhibits the clotting activity of said mature thrombin.
Claim 2
Dependent Claim
50 words
An applicator for use in the preparation of a fibrin sealant comprising a container means and an outlet means operably connected thereto, said container means having disposed therewithin a solution consisting essentially of fibrinogen, Factor XIII, mature thrombin and an agent that inhibits the clotting activity of said mature thrombin.
Claim 3
Dependent Claim
56 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII, mature thrombin and a calcium chelator; and ii) an outlet means operably connected to said container means, wherein said outlet means has a calcium salt disposed therewithin.
Claim 4
Dependent Claim
56 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII, mature thrombin and a calcium chelator; and ii) an outlet means operably connected to said container means, wherein said outlet means has a calcium salt disposed therewithin.
Claim 5
Dependent Claim
65 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII and mature thrombin, wherein said solution has a pH of less than about 5.5; and ii) an outlet means operably connected to said container means, wherein said outlet means has a neutralizing buffer salt disposed therewithin.
Claim 6
Dependent Claim
65 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII and mature thrombin, wherein said solution has a pH of less than about 5.5; and ii) an outlet means operably connected to said container means, wherein said outlet means has a neutralizing buffer salt disposed therewithin.
Claim 7
Dependent Claim
77 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII, mature thrombin and a photosensitive inhibitor of thrombin clotting activity; and ii) an outlet means operably connected to said container means, wherein said container means and said outlet means are constructed of a material that does not transmit light of a wavelength to which said inhibitor is sensitive.
Claim 8
Dependent Claim
77 words
A kit for use in the preparation of a fibrin sealant comprising an applicator that comprises: i) a container means having disposed therewithin a solution comprising fibrinogen, Factor XIII, mature thrombin and a photosensitive inhibitor of thrombin clotting activity; and ii) an outlet means operably connected to said container means, wherein said container means and said outlet means are constructed of a material that does not transmit light of a wavelength to which said inhibitor is sensitive.
Claim 9
Dependent Claim
30 words
The kit according to claim 4 wherein said outlet means is attached to a source of light that, when activated, emits light at a wavelength that inactivates said photosensitive inhibitor.
Claim 10
Dependent Claim
18 words
The kit according to claim 4 wherein said solution further comprises a second inhibitor of thrombin clotting activity.
Claim 11
Dependent Claim
14 words
The kit according to claim 6 wherein said second inhibitor is D-phenylalanyl-L-prolyl-L-arginine chloromethyl ketone.
Claim 12
Dependent Claim
14 words
The kit according to claim 4 wherein said photosensitive inhibitor is a cinnamoyl derivative.
