Long-term durability and highly reliable performance are achieved through advanced lead technology. A unique silicone tip technology is used in the design of the 6F thin Tendril STS Lead that ensures reliable performance and reduces pressure from the lead tip. It features the proprietary St. Jude Medical Optim Lead insulation that minimizes the risk of abrasion from the lead and offers durability that is long term. The soft silicone tip design and thin profile leads of the Tendril STS Lead ensures safety during implants and provides clinical benefits. In comparison to other 6F leads where the soft silicone tip is absent, there is a 30% reduction in tip pressure, and an increase of 35% in the surface area of the lead tip. There is also 6F introducer compatibility owing to the soft nature of the tip's material.
