Abstract: The present invention relates to methods, kits, and compositions for safe and efficient delivery of a bioagent to a targeted area of an organ. The method comprises preparing a suspension comprising the bioagent, a contrast agent, and a vehicle, wherein said suspension has an osmolarity from about 270 mOsm to about 440 mOsm; and dispensing at least a portion of said suspension into the targeted area. The invention further provides a kit for delivering a bioagent into a targeted area of an organ comprising: a delivery device; a contrast agent; and a vehicle.

Abstract: A method that allows for dry storage of bioprosthetic devices comprising a tissue component is provided. The method comprises the steps of providing a device comprising a chemically cross-linked animal tissue component; treating the tissue component with an aqueous solution comprising a biocompatible, water soluble, organic molecule comprising a plurality of carbon atoms and a plurality of hydroxyl groups for a time sufficient to allow equilibration between the fluids in the interstices of the tissue component and the aqueous solution; and then sterilizing the treated tissue component using a sterilizing gas or ionizing radiation. The present invention also relates to an implantable tissue component that can be stored dry. The tissue component is chemically-fixed and comprises within the interstices thereof a dimensional stabilizer selected from the group consisting of a polyhydric alcohol and derivatives thereof, a water soluble carbohydrate, and a water soluble gum.
