Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
44 words
An absorbable hemostatic composition for use in the control of osseous hemorrhage comprising from 10 to 50 percent by weight of the total composition of a hemostatic powder in a water-soluble, biocompatible base, said hemostatic powder comprising a mixture of fibrin and collagen powders.
Claim 2
Dependent Claim
44 words
An absorbable hemostatic composition for use in the control of osseous hemorrhage comprising from 10 to 50 percent by weight of the total composition of a hemostatic powder in a water-soluble, biocompatible base, said hemostatic powder comprising a mixture of fibrin and collagen powders.
Claim 3
Dependent Claim
33 words
