Vergenix Flowable Gel is indicated for the management of acute and chronic wounds

Vergenix™ Flowable Gel is an advanced wound care device primarily made of lyophilized Type I recombinant human Collagen (rhCollagen) . Vergenix Flowable Gel is supplied as a powder contained in a syringe that will be hydrated with saline, forming a gel. The Vergenix™ Flowable Gel provides a scaffold for cellular invasion and capillary growth. A secondary dressing to cover and secure the primary Vergenix™ Flowable Gel wound site followed by a final dressing application that will wrap the wound and surrounding area
