PreveLeak™ Surgical Sealant (PreveLeak™) is a sealant developed to seal surface holes formed during surgical repair of the circulatory system and to reinforce sutured anastomoses. When applied, PreveLeak™ creates an elastic biocompatible gel that seals suture holes or gaps formed between synthetic grafts or patches and native vessel anastomosis. PreveLeak™ adheres to the native tissues as well as synthetic materials, including PTFE and Dacron grafts, and facilitates sealing along anastomotic closure lines. After application, PreveLeak™ is a natural golden color and stays soft and flexible. Animal studies showed the majority of PreveLeak™ is largely resorbed by 12 months. PreveLeak™ is provided in a double-barreled syringe assembly containing equal volumes of purified bovine serum albumin (BSA) and polyaldehyde. PreveLeak™ is supplied in a double pouch, with two delivery tips and terminally sterilized. PreveLeak™ is ready to use once the pouch is opened, the syringe cap removed, the delivery tip is attached and the tip is primed. When the plunger is depressed, the two components are thoroughly mixed as they pass through the delivery tip. After applications, the sealant is allowed to remain undisturbed for at least 60 seconds before unclamping and exposing the anastomosis to arterial pressure. PreveLeak™ is applied as a viscous liquid that gels within approximately 10-15 seconds. PreveLeak™ is terminally sterilized by e-beam irradiation and is provided in a double pouch with two delivery tips. Additional sterile delivery tips are available separately. PreveLeak™ is provided for single-use only.
A sterile, bioabsorbable substance containing animal-derived material [e.g., bovine serum albumin (BSA)/cross-linking agent] intended to be used for internal surgical applications to bond or seal cut, incised, or resected body tissues (e.g., for vascular anastomosis) typically as an adjunct to standard methods of closure, to seal leaks, and to achieve haemostasis through tissue sealing. Disposable mixing devices/applicators may be included for preparation and application to anatomical sites. After application, this device cannot be reused.
