The ExpanSure dilator combines a sheath and dilator into a single tool, and facilitates larger dilation compared to a standard fixed curve sheath. The larger dilation optimizes left-heart procedures such as LAA closure and balloon ablation for atrial fibrillation, which require a large sheath to cross the heart’s septum from the right atrium.

“Crossing a 14 F sheath across the septum is often challenging, and, in certain cases, additional devices are needed to facilitate left-atrial access. Research has shown that introducing additional dilation devices may result in adverse events to the patient,” said Cleveland Clinic’s Dr. Oussama Wazni, Section Head of Electrophysiology, who performed the first U.S. ExpanSure dilator clinical case.

“In addition, clinical evidence has shown that the dilator-sheath transition found in typically-used devices can cause septal tissue to get caught, resulting in difficulty crossing the septum.”

The ExpanSure dilator is designed without the traditional dilator-sheath transition, aiming to eliminate use of added force to achieve crossing.

The device features a 12.5 Fr outer diameter, which pre-dilates the transseptal puncture to greater degree than typically-used devices. This facilitates smoother large sheath introduction to the left atrium. Its 0.035″ inner diameter allows physicians to use their preferred wire without having to exchange for a compatible dilator.

“Baylis is proud to offer a device uniquely designed to optimize transseptal access, allowing the physician’s primary focus to remain on delivering the necessary therapy to the patient,” said Robert Harrison, Director of Research and Development, Cardiology at Baylis Medical. “We are delighted to have partnered with Dr. Wazni and the Cleveland Clinic for this successful first clinical use.”
