Lifebond out of Caesarea Industrial Park, Israel has developed a new surgical sealant which is apparently stronger than the currently used blood-derived fibrin glues. The LifeSeal SLR staple line reinforcement sealant and LifeSeal Surgery sealant for general surgery are two main products from the company that are based on its proprietary hydrogel matrix technology, in which individual protein molecules tend to cross-link and form fibrin-like networks. The company plans to ask for US and European approval to market the material next year.
LifeBond’s technology functions through the rapid and biocompatible in situ cross-linking of structural proteins. As they cross-link, proteins in the physiological environment undergo a process of gelation to form an adhesive hydrogel matrix. The properties of the cross-linking reaction and the hydrogel matrix can be controlled to fit a variety of applications.
LifeSeal GI is comprised of LifeBond sealant provided in a specialized two-component applicator syringe. The mixed sealant is applied to anastomosis staple-line junctures in the GI tract to fortify the attachment and prevent leakage until full function is restored. The applicator thoroughly mixes the two components as they are applied and evenly dispenses the sealant onto the staple-line juncture. The sealant can be applied manually or as a gas-assisted spray.
Application of LifeSeal GI onto the staple line moderates tension on the staple line because it stabilizes the tissue sections in relation to each other and adds adhesive strength to the junction. Furthermore, LifeSeal GI seals off the staple holes and narrows the spaces in between each staple. Thus, leakage, bleeding, and tearing at the staple line can be reduced, especially in diseased and fragile tissue.
LifeSeal Surgical sealant is provided in a variety of specialized two-component applicators. The mixed sealant is applied to a wound site or staple-line juncture to prevent fluid or blood leakage until full physiological function is restored. The applicator thoroughly mixes the two components as they are applied and evenly dispenses the sealant onto the wound site or staple-line juncture. The sealant can be applied manually or as a gas-assisted spray. The precise application method can be altered to optimize sealant use for specific applications.
