Abstract
Official abstract text for this publication.
A device or system includes a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough. The mixer is in communication with sources or streams of at least two separate components which, when mixed, form a combined fluid stream. The sources or streams may be, at least initially, on opposite sides of the mixer, or the sources or streams may be on the upstream side of the mixer with an outlet disposed downstream of the mixer. A related method may include providing a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and selecting a material for the mixer based on physical characteristics of said material, said characteristics including a selected one or more of mean flow pore size, thickness and porosity volume.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of treating a biological tissue or wound, comprising: preparing a fibrin foam by mixing a volume of a fibrinogen solution, a volume of a thrombin solution, and a volume of air, said fibrin foam comprising (1) a three-dimensional reaction product of fibrinogen and thrombin having a percent crosslinking of about 23% to about 36%, and (2) air bubbles entrained within the reaction product, the air bubbles having a volume of about 50% to about 70% of the fibrin foam; and applying the fibrin foam to the biological tissue or wound.
