Hypro-Sorb^® R is a sterile material which is ready for immediate use as a haemostatic. It is used in a number of areas such as surgery, traumatology, stomatology, and ophtalmology, as well as areas where effective hemostatis of parenchymatous or surgical haemorrhage is needed. Hypro-Sorb^® R is a fully biocompatible and absorbable atelocollagen haemostatic with excellent tissue compatibility. Hypro-Sorb^® F membranes are used as barriers which adopt themselves to a bone defect and, at the same time, help to heal soft tissues where the method of guided tissue and bone regeneration is used. Since Hypro-Sorb^® is fully bio-absorbable, no further operation for its removal is needed.
