Solid dressing for treating wounded tissue and processes for mixing fibrinogen and thrombin while preserving fibrin-forming ability, compositions produced by these processes, and the use thereof

Fibrin Sealant products are used for topical hemostasis and tissue adherence. They are composed of two main reagents, fibrinogen and thrombin. When mixed in solution fibrinogen is converted to fibrin upon the addition of activated thrombin. Therefore typically these two components are stored separately in a lyophilized or liquid state, and mixed, upon or immediately before, application to a patient. While effective, these products require significant preparation that must take place immediately before application, thus delaying treatment and limiting the use of these haemostatic products to the treatment of mild forms of low pressure and low volume bleeding. Attempts to eliminate this delay and expand the usefulness and effectiveness of these products have resulted in products produced by processes that require the separation of these components and their deposition in distinct layers within the product. The processes described herein permit the mixing of fibrinogen and thrombin during product manufacture, without excessive fibrin formation. The resulting ‘pre-mixed’ fibrin sealant material can then be stored in either a frozen or dried state, or suspended in a non-aqueous environment. Activation of the material to form therapeutic fibrin sealant is accomplished by permitting the product to thaw (if frozen) or by the addition of water or other aqueous fluid, including blood, or other bodily fluids, if dried or suspended in a non-aqueous environment. The resulting material can be used to make a product in which a pre-mixed form of activatable fibrin sealant is a desired component.

TISSUE PATCH

Tissue patches and associated systems and methods are described. Certain embodiments are related to inventive systems and methods in which tissue patches can be made quickly and robustly without the use of complicated fabrication or sterilization equipment. For example, in some embodiments, tissue patches are made by applying a compressive force to a liquid medium comprising fibrinogen (and/or fibrin) between two surfaces (e.g., within a syringe or other chamber). A filter can be placed within or near the volume in which the compressive force is applied to the liquid medium such that unwanted material (e.g., water, blood cells, and the like) is passed through the filter while desirable components (e.g., fibrin, fibrinogen, and/or other desirable components) are retained by the filter to form the patch. In this way, the concentration of fibrin (and/or fibrinogen) within the liquid medium can be increased, potentially dramatically, as the compressive force is applied to the liquid-containing composition. In addition, in some embodiments, at least a portion of the fibrinogen and/or fibrin can chemically react (e.g., the fibrinogen can polymerize to form fibrin and/or the fibrin can cross-link) during application of the compressive force. Reaction and concentration can lead to the formation of a highly-concentrated, mechanically robust patch that can be handled relatively easily and provide good structural reinforcement at a wet site, such as a bleeding wound. 1. (canceled)2. A patch , comprising:a primer region comprising a water-activated polymeric adhesive; anda solid matrix positioned over at least a portion of the primer region, the water-activated polymeric adhesive comprises one or more polymers of acrylic acid cross-linked with a polyalkenyl ether and/or a divinyl alcohol; and', 'the patch is configured for application to a tissue surface., 'wherein3.
