Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
53 words
A method of reducing mediastinal fibrinolysis in open heart surgery patients, comprising the steps of: topically applying a hemostatic solution to the mediastinum followed by closing the pericardium, said solution comprising a saline solution at body temperature of a pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 2
Independent Claim
53 words
A method of reducing mediastinal fibrinolysis in open heart surgery patients, comprising the steps of: topically applying a hemostatic solution to the mediastinum followed by closing the pericardium, said solution comprising a saline solution at body temperature of a pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 3
Dependent Claim
57 words
The method of claim 1 wherein said solution comprises from 0.5 to 5.0 grams of calcium chloride, 2 grams to 20 grams of epsilon-aminocaproic acid, 0.3 to 3.0 grams of protamine, 2,500 units to 15,000 units of thrombin and 0.05 mgm to 4.0 mgm of norepinephrine, each of said quantities based upon one liter of saline solution.
Claim 4
Dependent Claim
38 words
The method of claim 2 wherein said quantities comprises about 1 gram of calcium chloride, 10 grams of epsilon-aminocaproic acid, 1 gram of protamine, 5000 units of thrombin and 1 mg of norepinephrine, each in said 1 liter.
Claim 5
Independent Claim
104 words
A method of reducing mediastinal fibrinolysis in open heart surgery patients, comprising the steps of: topically applying a hemostatic solution by bathing the pericardial sac and wound with said solution for a pharmacalogically adequate time while slowly adding additional solution while aspirating the overflow, followed by installation in the pericardium of a quantity of solution after closure of the sternum and until the skin closure and dressing application are begun, at which time the pericardium and mediastinum is drained, said solution comprising a saline solution at body temperature of a pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 6
Independent Claim
104 words
A method of reducing mediastinal fibrinolysis in open heart surgery patients, comprising the steps of: topically applying a hemostatic solution by bathing the pericardial sac and wound with said solution for a pharmacalogically adequate time while slowly adding additional solution while aspirating the overflow, followed by installation in the pericardium of a quantity of solution after closure of the sternum and until the skin closure and dressing application are begun, at which time the pericardium and mediastinum is drained, said solution comprising a saline solution at body temperature of a pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 7
Dependent Claim
14 words
The method of claim 4 wherein said time is from 3 to 10 minutes.
Claim 8
Dependent Claim
21 words
The method of claim 5 where said time is about 5 minutes and said quantity is from 100 to 300 cc.
Claim 9
Dependent Claim
12 words
The method of claim 6 where said quantity is about 200 cc.
Claim 10
Dependent Claim
56 words
The method of claim 4 wherein said solution comprises from 0.5 to 5.0 grams of calcium chloride, 2 grams to 20 grams of epsilon-aminocaproic acid, 0.3 to 3.0 grams of protamine, 2500 units to 15000 units of thrombin and 0.05 mgm to 4.0 mgm of norepinephrine, each of said quantities based upon liter of saline solution.
Claim 11
Dependent Claim
36 words
The method of claim 8 where said quantities comprises about 1 gram of calcium chloride, 10 grams of Amicar, 1 gram of protamine, 5000 units of thrombin and 1 mg of norepinephrine, each in said liter.
Claim 12
Dependent Claim
21 words
A solution comprising: a saline solution of pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 13
Dependent Claim
21 words
A solution comprising: a saline solution of pharmacologically active mixture of calcium chloride, epsilon-aminocaproic acid, protamine, thrombin and norepinephrine dissolved therein.
Claim 14
Dependent Claim
57 words
The solution of claim 10 where said solution comprises from 0.5 to 5.0 grams of calcium chloride, 2 grams to 20 grams of epsilon-aminocaproic acid, 0.3 to 3.0 grams of protamine, 2500 units to 15000 units of thrombin and 0.05 mgm to 4.0 mgm of norepinephrine, each of said quantities based upon one liter of saline solution.
Claim 15
Dependent Claim
37 words
The solution of claim 11 where said quantities comprise about 1 gram of calcium chloride, 10 grams of epsilon-aminocaproic acid, 1 gram of protamine, 5000 units of thrombin and 1 mg of norepinephrine, each in said liter.
