Elastomeric surgical sealant for hemostasis of cardiovascular anastomosis under full heparinization.

Purpose: We developed a novel surgical sealant, a viscous diisocyanated prepolymer, applicable to arterial hemostasis. The purpose of this study is to evaluate hemostatic effect of this surgical sealant under heparinized conditions.

Methods: The effectiveness of this sealant was verified by applying it to the end-to-end anastomosis of canine carotid arteries.
