FDA Approves WiSE® System

In a remarkable advancement for heart failure treatment, EBR Systems, Inc. has recently received FDA approval for the WiSE® System. This novel device stands out as the world’s first and only leadless left ventricular endocardial pacing (LVEP) solution, pointing towards a future of innovative cardiac care.

The Breakthrough in Cardiac Treatment

Traditionally, cardiac resynchronization therapy (CRT) has relied on lead-based systems to treat heart failure. However, these systems often fall short when it comes to several patient populations, particularly those facing anatomical challenges or lead-related complications. The WiSE® System changes this landscape dramatically—allowing physicians to implement a leadless approach that closely mimics the heart's natural conduction pathways.

With its endocardial method, the WiSE System not only circumvents the limitations posed by conventional CRT but also presents an alternative for patients who have been sidelined from traditional therapies. This leap in technology paves the way for entirely new treatment avenues for individuals who face barriers in conventional CRT applications.

Catering to Underserved Patients

Prior to the introduction of the WiSE System, many individuals in need of CRT were left with inadequate options. The WiSE® was designed specifically to cater to those patients, covering critical demographics that conventional methods often overlook:

• - Patients with challenging anatomical structures where the standard left ventricular (LV) lead placement is non-viable.
• - Individuals with acute or chronic LV lead malfunctions that contraindicate the use of traditional devices.
• - High-risk patients who exhibit significant procedural hazards when implanting standard LV leads.
• - Leadless pacemaker recipients who are in need of CRT but typically qualify poorly for standard upgrades.

By addressing these distinct groups, the WiSE System enables an expansion in CRT accessibility, thereby ensuring that a greater number of patients receive the care they need.

Promising Clinical Results

The groundbreaking nature of the WiSE® System has been substantiated by the SOLVE-CRT trial, which provided compelling data indicating its efficacy:

• - A 16.4% reduction in left ventricular end-systolic volume (LVESV)—a critical marker indicating improved heart function, showcasing statistical significance with a p-value of 0.003.
• - A shortening of QRS durations by an average of 39ms, indicating a notable electrical resynchronization effect.
• - Over 55% of participants observed an improvement of at least one NYHA functional class, with an additional 40% remaining stable throughout the treatment course.

These results point toward a significant improvement in quality of life for patients struggling with heart failure, highlighting the transformative potential of this innovative device.

Seamless Integration with Existing Technologies

The WiSE® System is designed for compatibility with already-implemented cardiac devices such as pacemakers and implantable cardioverter-defibrillators (ICDs). This seamless integration is facilitated through a subcutaneous ultrasound transmitter that powers an ultra-compact electrode implanted within the left ventricle—eliminating the need for leads and the navigational complexities associated with them.

Empowering Medical Professionals and Patients

As John McCutcheon, President and CEO of EBR Systems, stated: “We’re thrilled for the heart failure patients previously untreated due to existing CRT lead-based device limitations.” The FDA approval marks a significant milestone, celebrating concerted efforts by EBR’s dedicated team while empowering electrophysiologists with a new, crucial tool for enhancing patient outcomes. After 22 years in pre-commercialization, EBR Systems is set to grow into a major player within the medical device industry.
