Sealants for Skin and Other Tissues
The present invention relates to sealants for skin and other tissues. The sealants include an electroprocessed material. The sealants may contain more than one electroprocessed materials and may contain additional substances. The invention further relates to methods of making and using such sealants.
1 . A composition comprising fibers of electroprocessed collagen or electroprocessed fibrinogen, wherein the fibers have an average diameter between about 50 nm and about 10 μm, and the composition is effective as a sealant.
2 . A composition comprising isolated fibers comprising collagen or fibrinogen, wherein the fibers have an average diameter between about 50 nm and about 10 μm, and the composition is effective as a sealant.
3 . A composition comprising electroprocessed fibrinogen, wherein the electroprocessed fibrinogen is insoluble in water.
4 . A composition comprising fibrinogen, wherein the fibrinogen is insoluble in water.
5 . A composition comprising electroprocessed fibrinogen or electroprocessed collagen, wherein the electroprocessed fibrinogen or the electroprocessed collagen is present as fibers having a repeating banding pattern.
6 . A composition comprising an electroprocessed material, wherein the electroprocessed material is effective as a sealant.
7 . The composition of claim 1 , wherein the composition is effective to cause hemostasis.
8 . The composition of claim 1 , further comprising a substance.
9 . The composition claim 8 , wherein the substance is selected from thrombin, aprotinin, Factor XIII, calcium chloride, hydroxyapatite, a fibrinolytic inhibitor, a fibrinolytic agent, fibronectin, or a combination thereof.
10 . (canceled)
11 . (canceled)
12 . A method of manufacturing a composition, comprising electroprocessing one or more electrically-charged solutions comprising collagen, fibrinogen, or a combination thereof under conditions effective to electrodeposit electroprocessed material onto a substrate to form fibers having an average diameter between about 50 nm and about 10 μm.
13 . A method of manufacturing the composition of claim 1 , comprising electroprocessing one or more electrically-charged solutions comprising material under conditions effective to electrodeposit electroprocessed material onto a substrate to form the electroprocessed material.
14 . A method of providing physical reinforcement to tissue, repairing an injury or defect in tissue, promoting healing or causing hemostasis comprising applying the composition of claim 1 to tissue requiring physical reinforcement, repair, healing, hemostasis or a combination thereof.
