Boston Scientific presented new versions of its ablation and diagnostic catheters at the 15th annual Boston Atrial Fibrillation Symposium (BAFS) last week.

The Natick, Mass.-based company featured its Blazer Prime, a temperature ablation catheter, redesigned to gain more torque and control.

“The ideal catheter should serve as a link between the doctor's hand and the electrodes that are being manipulated inside the heart. Getting something that is this responsive and predictable as possible is the goal,” said David L. McGee, vice president of marketing at Boston Scientific.

According to McGee, the Blazer Prime has fiber-reinforced distal segments for better response. In addition, the new design has “stiffened up” the proximal shaft catheter to gain a better push response.

The company said the extra support in the distal segments improves lateral contact and back steering strength, while enhancing torque.

The Blazer Prime was launched in the U.S. two months ago and is available in small and large tip formulas and various curve configurations.

According to McGee, the Dx-20, a bidirectional duodecapolar diagnostic catheter, “borrows from the basic Blazer catheter” to offer bidirectional control with its various curve sizes. The curve size utilizes 20 electrodes for mapping right atrial flutter applications. In addition, the device is used during flutter line procedures following an AF procedure. The technology offers an extended distal tip to lower the risk of vessel injury.

Additionally, the device’s curve-lock feature creates a stable reference point and works to hinder device movement during a procedure.
