CRANBURY, NJ -- (MARKET WIRE) -- February 06, 2007 -- Valera Pharmaceuticals, Inc. (NASDAQ: VLRX) today announced it has initiated a porcine model study to establish safety and effectiveness necessary to support the submission of a 510k device application with the Food and Drug Administration for a polymer-based flexible biodegradable ureteral stent. Valera believes that the successful development a pliable, biodegradable ureteral stent, which could be voided naturally from the body with the discharge of urine, potentially represents a significant advance over existing plastic and metallic ureteral stents which are non-degradable and require physician intervention to extract from the body.
