Effectiveness of Glycerol Mono-oleate as a Biosealant.

Background: The number of femoral artery catheterizations will increase over the next decade to more than 9 million worldwide. Accordingly, a new era of access site management with vascular closure techniques utilizing biologics are being developed and implemented. Glycerol mono-oleate (GMO) is one such biologic - a biodegradable compound that changes from a solid phase to a bioadhesive swollen semisolid phase when exposed to aqueous solutions and heat.
