HeliPlug Absorbable Collagen Wound Dressing are made from purified bovine tendon which helps reduce risk of adverse reaction to collagen material. These tube-shaped collagen plugs help control bleeding, protect the wound site after dental surgery and promote tissue growth. Their size is ideal for exraction and biopsy sites. HeliPLUG comes in individual sterile packaging and is absorbed within 10-14 days after placement.
