Reducing Burden for Patients with New Atrial Fibrillation Treatment System

World’s first high-frequency heating balloon, developed in Japan

What is atrial fibrillation?

A normal heart beats at a rate of around 60 to 100 beats per minute. Atrial fibrillation is a type of arrhythmia in which the heart beats irregularly at a rate of up to 300 or more beats per minute, thereby increasing the risk of heart failure and stroke. Along with medication, catheter ablation is effective for treating atrial fibrillation, through pointed cauterization of the left atrium in the heart.

  • 1 The heating balloon-based catheter ablation system for treating paroxysmal atrial fibrillation comprises three medical devices: (1) SATAKE-HotBalloon™ Catheter (high-frequency balloon catheter); (2) SATAKE-HotBalloon™ Generator (specialized high-frequency generator); and (3) Treswaltz™ catheter insertion guiding sheath.

The Toray Group and Dr. Shutaro Satake, a leader in the treatment of atrial fibrillation, co-developed the SATAKE-HotBalloon™ System, which is the world’s first heating-balloon catheter device for treating this disorder. The system uses a flexible balloon that presses tightly against the treatment area to broadly ablate the area causing atrial fibrillation. Due to the mechanism of the treatment, the system can reduce the risk of blood clot formation due to the procedure.

The Toray Group has more than 30 years of experience in co-developing medical devices and has earned a strong reputation for its expertise at turning doctors’ ideas into actual products. In addition to making products, we will work to put the conditions in place to make it even safer to use our products.

Rapidly securing improvements through research in the field

With a medical device such as a catheter, it is critical to make improvements as quickly as possible in order to lessen the burden on patients, so it is crucial to develop the device in concert with specialist physicians and medical settings. In developing Toray’s ablation system, we started by trying to develop the best balloon heating method, and ultimately arrived at using a high frequency of 1.8 MHz to heat the balloon. We are continuing to make improvements to the system, in order to make it easier to use and more effective.

We believe that the core technology used in this system can be applied to treat other conditions, and we will keep developing applications for the system, working together with leading doctors in their respective fields.
