Francis B. Maddalo - Needham MA
Stephen N. Eldridge - Cranston RI

Assignee:

C. R. Bard, Inc. - Murray Hill NJ

International Classification:

A61B 1708

US Classification:

606214

Abstract:

A collagen fiber and methods for producing and using the collagen fiber of the inventions to prepare hemostatic fabrics to control bleeding are provided. The collagen particles (e. g. , fibrils) of the fiber, preferably, have a hemostatic activity that is equivalent to the hemostatic activity of the collagen particles from which the fiber is formed. The collagen fibers of the invention and hemostatic fabrics formed thereof optionally include hemostatic agents and/or other therapeutic agents, to further promote hemostasis and wound healing.

International Classification:

A61B 1708

US Classification:

606214, 128DIG 8, 106122, 514801, 424423

Abstract:

A hemostatic device formed of collagen particles and methods for producing and using the hemostatic device to control bleeding are provided. The collagen particles of the hemostatic device have a hemostatic activity that is equivalent to the hemostatic activity of the collagen particles from which the hemostatic device is formed. More preferably, the hemostatic devices are formed of Avitene flour and the collagen particles of the hemostatic devices of the invention have a hemostatic activity equivalent to the hemostatic activity of Avitene flour. The hemostatic devices optionally include hemostatic agents and/or therapeutic agents, to further promote hemostasis and wound healing.
