In accordance with the present invention a novel fibrin polymer structure is disclosed. The novel fibrin polymer structure useful, for example, as a surgical sealant, is comprised of a plurality of discrete, droplets of polymerizing or polymerized fibrin each encapsulated by a "skin" of fibrin polymer. These fibrin-skin encapsulated droplets are applied so as to be built up one upon the other, layer by layer, to form an integral sealant structure. The cumulative effect of the encapsulating skins of those droplets which form the sealant surface is a surface skin which unexpectedly resists cell penetration but enhances cell migration across the surface. The sealant structure of the present invention can be prepared by spray delivery of fibrin polymer forming materials wherein the time required for the materials to commence polymerizing after mixing is less than or equal to the transit time of said materials from the applicator tip to the target surface.

L'invention concerne une nouvelle structure polymère de fibrine utile, par exemple, comme agent de scellement chirurgical et constituée d'une pluralité de gouttelettes séparées de fibrine de polymérisation ou polymérisée, chacune étant encapsulée par une <= peau >= de polymère de fibrine. Ces gouttelettes encapsuleés dans la peau de fibrine sont appliquées de manière à tomber l'une sur l'autre, couche sur couche, de manière à former une structure étanche solidaire. L'effet cumulatif des peaux d'encapsulation de ces gouttelettes formant une surface étanche se traduit par une peau de surface qui résiste à la pénétration cellulaire, ce qui est une nouveauté, tout en améliorant la migration cellulaire à travers la surface. La structure de scellement peut être préparée par la vaporisation d'agents formant un polymère de fibrine. La durée requise pour que les agents commencent à polymériser après leur mélange est inférieure ou égale à la durée de transit de ces agents du bout de l'applicateur à la surface cible.
