a medical adhesive that bonds well to human tissue while curing in a fast , controllable mariner . in a preferred form , the medical adhesive includes an oligomer , a hydrogel and / or water soluble polymer and a photoinitiator . preferred oligomers include epoxides , urethanes , polyethers , polyester or a combination thereof . hydrogels and water soluble polymers aid adhesion to moist surfaces , such as skin tissue , because they are hydrophilic and biodegradable , preferred hydrogels include polymer hydrogels . suitable water soluble polymers include polyethylene oxide ) and poly - 2 - oxazoline . the photoinitiator is used to obtain fast , controllable curing of the adhesive compound . curing takes place on demand when ultraviolet light is applied to the medical adhesive . to increase adhesion as well as to control flexibility and toughness , the medical adhesive may also include one or more monomers . suitable monomers include acrylates and vinyls .
