Protein Polymer Technologies Receives FDA 510(k) Clearance for New Embolization Convenience Kits

SAN DIEGO, CA--(Healthcare Sales & Marketing Network)--Feb 6, 2006 -- Protein Polymer Technologies, Inc. (OTC BB:PPTI.OB ), a biotechnology device company that is a pioneer in protein design and synthesis, today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market its new convenience kits which are packaged with Surgica Corporation's proprietary foam embolization products. These three new convenience kits have been designed to offer improved ease of use and overall procedure efficiency for physicians in the field of Interventional Radiology.

With the new, more user-friendly convenience kits, PVA Plus(TM) and MicroStat(TM) spherical foam embolization particles are pre-packaged dry in a sterile syringe, ready for rapid hydration and administration. Based on Surgica's patented manufacturing process, these particles, which are porous throughout, rapidly equilibrate in contrast media. The new dry particle kits offer physicians the means to prepare their embolization injections in a quick, simple and clean manner.

The newly developed MaxiStat(TM) particles, which offer the advantages of a spherical PVA foam embolization particle as an alternative to small coils for up to medium-sized vessels, are packaged individually, dry in a vial, hydrating almost instantaneously in contrast media. Larger than other spherical PVA particles, MaxiStat(TM) particles are compressible and resilient, enabling delivery of a 4 mm particle through a 0.38" guidewire compatible catheter.

"The 510(k) clearance of the new convenience kits within six weeks of executing the license with Surgica represents a significant milestone for PPTI," said William N. Plamondon III, Chief Executive Officer of PPTI. "Capitalizing on our internal development and regulatory capabilities, these new products offer distinct advantages to the physician over other products in the marketplace."

PPTI completed a worldwide License Agreement with Surgica for its products and technology in December 2005, acquiring the exclusive rights to develop and commercialize Surgica's three FDA-cleared PVA based embolization products -- PVA Plus(TM), MicroStat(TM) and MaxiStat(TM) and one additional product under development, Blocker(TM).

Embolization, a minimally invasive procedure performed by interventional radiologists, is used to treat a variety of medical conditions including neurovascular conditions, uterine fibroids and inoperable liver cancer. PPTI estimates a conservative annual market potential for embolization could exceed $400 million in the U.S. and $800 million worldwide.
