Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
71 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: applying a suitable solvent to the biocompatible surgical device; applying to the wetted biocompatible surgical device a β-D-glucan powder such that the β-D-glucan powder dissolves into the solvent to form a substantially uniform coating upon the biocompatible surgical device; and evaporating the solvent from the substantially uniform coating of β-D-glucan upon the biocompatible surgical device.
Claim 2
Independent Claim
71 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: applying a suitable solvent to the biocompatible surgical device; applying to the wetted biocompatible surgical device a β-D-glucan powder such that the β-D-glucan powder dissolves into the solvent to form a substantially uniform coating upon the biocompatible surgical device; and evaporating the solvent from the substantially uniform coating of β-D-glucan upon the biocompatible surgical device.
Claim 3
Dependent Claim
22 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 1 wherein said β-D-glucan is a cereal-derived β-D-glucan.
Claim 4
Dependent Claim
27 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 1 wherein said β-D-glucan is derived from one of coats, barley, and wheat.
Claim 5
Independent Claim
79 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: preparing an aqueous solution comprising a β-D-glucan; placing the aqueous solution of β-D-glucan in a spraying mechanism; coating a predetermined portion of the surface of the biocompatible surgical device with the aqueous β-D-glucan solution by spraying the aqueous solution onto the surface of the biocompatible surgical device; and drying the aqueous solution of β-D-glucan deposited on the surface of the biocompatible surgical device.
Claim 6
Independent Claim
79 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: preparing an aqueous solution comprising a β-D-glucan; placing the aqueous solution of β-D-glucan in a spraying mechanism; coating a predetermined portion of the surface of the biocompatible surgical device with the aqueous β-D-glucan solution by spraying the aqueous solution onto the surface of the biocompatible surgical device; and drying the aqueous solution of β-D-glucan deposited on the surface of the biocompatible surgical device.
Claim 7
Dependent Claim
22 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 4 wherein said β-D-glucan is a cereal-derived β-D-glucan.
Claim 8
Dependent Claim
27 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 4 wherein said β-D-glucan is derived from one of oats, barley, and wheat.
Claim 9
Independent Claim
85 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: preparing an aqueous solution comprising a β-D-glucan; placing said aqueous solution in an electrostatically charged spraying device; placing the biocompatible surgical device upon a support structure having an electrostatic charge opposite that of the spraying device; spraying the electrostatically charged aqueous solution onto the oppositely charged biocompatible surgical device so as to form a coating thereon; and, drying the aqueous solution on the surface of the biocompatible surgical device.
Claim 10
Independent Claim
85 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: preparing an aqueous solution comprising a β-D-glucan; placing said aqueous solution in an electrostatically charged spraying device; placing the biocompatible surgical device upon a support structure having an electrostatic charge opposite that of the spraying device; spraying the electrostatically charged aqueous solution onto the oppositely charged biocompatible surgical device so as to form a coating thereon; and, drying the aqueous solution on the surface of the biocompatible surgical device.
Claim 11
Dependent Claim
22 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 7 wherein said β-D-glucan is a cereal-derived β-D-glucan.
Claim 12
Dependent Claim
27 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 8 wherein said β-D-glucan is derived from one of oats, barley, and wheat.
Claim 13
Independent Claim
60 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: applying an aqueous solution comprising β-D-glucan to the surface of a biocompatible surgical device; drawing a vacuum around the coated biocompatible surgical device; removing the biocompatible surgical device from the vacuum; and, drying the aqueous solution on the surface of the biocompatible surgical device.
Claim 14
Independent Claim
60 words
A method of applying an immunostimulating agent to a biocompatible surgical device comprising the steps of: applying an aqueous solution comprising β-D-glucan to the surface of a biocompatible surgical device; drawing a vacuum around the coated biocompatible surgical device; removing the biocompatible surgical device from the vacuum; and, drying the aqueous solution on the surface of the biocompatible surgical device.
Claim 15
Dependent Claim
22 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 10 wherein said β-D-glucan is a cereal-derived β-D-glucan.
Claim 16
Dependent Claim
27 words

Claim 17
Dependent Claim
27 words
The method of applying an immunostimulating agent to a biocompatible surgical device of claim 10 wherein said β-D-glucan is derived from one of yeast, bacteria, and fungus.
Claim 18
Independent Claim
39 words
A method of promoting the acceptance of a surgical device into the tissues into which the surgical device is implanted, the method comprising the step of applying an immunostimulating agent comprising a β-D-glucan to the surgical device before implantation.
