LIQOSEAL3 Dural seal from Polyganics

Preventing cerebral fluid from leaking through a sutured dura after an invasive procedure, Dutch chemists at Polyganics [ Groningen, The Netherlands] developed a “two-layer dural sealant patch, employed its proprietary synthetic bioresorbable polymers already marketed for tissue repair and regeneration. One layer consists an adhesive foam made of the bioresorbable co-polyester already used for the company’s Neurolac nerve guide, Neurocap nerve cap, and Vivosorb, along with a PEG adhesive component and a buffer salt. The second sealing layer is a sheet made from a blue-colored bioresorbable polyurethane, similar to that used in Polyganics’s Nasopore nasal dressing, as well as the same co-polyester as the foam.” MORE
