An innovative lead insulation material for cardiac leads used with pacemakers and ICDs is now FDA approved and available in the U.S. Optim, from St. Jude Medical, is the first silicone-polyurethane co-polymer material created specifically for cardiac lead use.
Designed for long-term reliability as well as better flexibility and handling during device implantation, Optim insulation is a material that blends the biostability and flexibility of high-performance silicone rubber with the strength, tear and abrasion resistance of polyurethane. Optim is being introduced on two of St. Jude’s newest leads, the Riata ST Optim ICD lead and the Tendril ST Optim pacing lead.
"This new lead insulation blends the best characteristics of polyurethane and silicone into an innovative material that handles well for me in surgery and provides outstanding durability for my patients," said Steven Kutalek, M.D., Drexel University College of Medicine, Philadelphia, PA.
