BioBag is a larval debridement therapy (not available in the U.S.) INTENDED USES: Removes the dead tissue from wounds. CLAIMED FEATURES: Disinfected larvae of Lucilia sericata in a sterile polyester net bag with a sterile PVA spacer cube. BioBag is a biosurgical wound treatment consisting of disinfected, living larvae of the greenbottle fly Lucilia sericata, also known as Larval Debridement Therapy (LDT). The larvae remove the dead tissue from wounds, this process of removal of dead tissue from wounds (known as debridement) is often an essential step before wound healing can occur. Debridement results from the action of proteolytic larval enzymes liquefying the necrotic tissue and scoring of the tissue by the mouthparts of the larvae; this allows the larval enzymes to penetrate more effectively.

Product Information

Debridement is important to promote wound healing. Debridement is the process through which clinicians remove dead tissue and foreign materials from wounds. Dead tissue may be of different colors: black, gray, yellow or white. There are several methods of wound debridement, and debridement with larvae is one of them.
Rapid debridement can be achieved in as little as one treatment with disinfected larvae. Larvae are instinctively selective and eat only the dead tissue of a wound. They are precise, clean, quick and clinically effective. Although debridement with disinfected larvae can be a good solution for healthy and natural wound debridement, psychological and aesthetic concerns are understandable in contemporary culture. They either come loose and can be placed under a bandage, or come trapped in bandages. Patients need to consult their clinicians before opting for this type of debridement.

Among requirements, the wound needs to have devitalized, fibrotic, nonviable tissue, infection, necrosis, foreign matter, and the debridement method used needs to be recognized by Medicare as a proven method, supported by valid scientific literature. Larval debridement is one of these methods.
