Chemically-modified quaternary-structured fiber collagens of minimum molecular length, diameter and periodicity, and containing a relatively high positive electrostatic charge are claimed as hemostatic agents. Specific examples are guanidinated, esterified, and guanidinated-esterified collagen fibers of the type described.

Chemically-modified fiber collagen hemostatic agents

Soft contact lenses are made from purified fiber collagen and mixtures of such fiber with purified solubilized collagen.

Fiber collagen contact lens

Soft contact lenses are made from solubilized, defatted, transparent, cross-linked collagen, and/or chemically-modified collagen.

Collagen soft contact lens

Polymers of quaternary-structured collagen of minimum length, diameter and periodicity, and containing a relatively high positive electrostatic charge are claimed as hemostatic agents. Specific examples are guanidnated polymers of the type described, esterified polymers, and esterified-guanidinated polymers.

Chemically and enzymatically modified collagen hemostatic agent

Chemically-modified collagen membrane prepared at physiologic pH and soluble thereat provides a carrier for ophthalmic medication leaving no removable material after drug release.
