What is it? CoSeal® is a medical sealant that is used to help stop leaks in blood vessels. It is made of two chemicals called polyethylene glycols (PEGs), and does not include any human or animal materials.

How does it work? The two PEGs are mixed together as they are applied during surgery to form a glue-like product which seals the area. CoSeal® fills gaps and plugs holes in the patient's blood vessels.

When is it used? CoSeal® is used to help seal leaks around sutures in natural or artificial blood vessels.

What will it accomplish? In a research study, immediately after treatment, leaking suture areas were successfully sealed in 47% of patients treated with CoSeal®, as compared to only 20% of patients who received another kind of treatment to stop bleeding. After 10 minutes, leaking suture areas were successfully sealed in 81% of patients treated with CoSeal®, as compared to 78% of patients who received another kind of treatment to stop bleeding.

When should it not be used? CoSeal® should not be used:

  • Inside blood vessels,
  • As a replacement for sutures or staples

The safety and performance of CoSeal® have not been determined in children and pregnant women or when used in quantities greater than 16 milliliters per patient.
