Researchers from LLNL, Texas A&M and Memory Medical develop blood-flow medical plug

Researchers from Lawrence Livermore National Laboratory (LLNL), Texas A&M University and Santa Clara-based Memory Medical have jointly developed a foam plug that prevents blood flow to diseased vessels.

The IMPEDE Embolization Plug is made from a shaped-memory polymer (SMP) initially developed at LLNL for weapons applications. The device can be crimped to fit any diagnostic catheter for delivery into a diseased blood vessel. Almost instantly, the foam in the plug expands to divert blood flow from the diseased vessel toward healthy vessels.

According to its developers, the technology improves on metal plugs and coils, as it is less likely to tear through vessel walls and is easier to navigate through the vascular system. In addition, the plug degrades over time to be replaced by the patient’s natural connective tissue and collagen, eliminating the risk of long-term inflammation.

Under an agreement signed by all three parties, Texas A&M will have access to a significant portfolio of LLNL intellectual property related to the SMP material, while LLNL will have access to future developments. Tech transfer agreements for commercialization were executed between LLNL and Shape Memory Medical.
