Abstract
The present invention provides a kit for preparing a composition for sealing a lung tract, comprising: (a) a first component comprising: (i) a fibrinogen solution, and (ii) prewet gelatin particles in an aqueous solution; and (b) a second component comprising: (i) a thrombin solution, and (ii) a dry gelatin powder; wherein the first and second components are stored separately and configured for mixing together to form a composition that is flowable and cross-linkable. The composition may be used to seal tissue tracts such as lung tissue tracts.
