Medtronic Developed Novel PulseSelect™ Pulsed Field Ablation System to Treat Atrial Fibrillation

Medtronic has introduced the groundbreaking PulseSelect Pulsed Field Ablation (PFA) system, a cutting-edge advancement designed to effectively address both paroxysmal and persistent atrial fibrillation (AF).

The PulseSelect PFA system boasts distinct safety features and facilitates swift, efficient pulmonary vein isolation (PVI) by ensuring consistent and predictable energy delivery, coupled with enhanced catheter manoeuvrability. 

Engineered with a focus on seamless integration, this system is purpose-built to smoothly align with a clinician's preferred workflow, facilitating a straightforward transition to PFA procedures.

The PulseSelect PFA system is a pioneering advancement that propels the EP (electrophysiology) community into a transformative era of AF (atrial fibrillation) ablation.
The PulseSelect PFA system also includes the following features:

• The PulseSelect system redefines versatility by its plug-and-play design, offering seamless compatibility with any mapping system or even functioning independently using only fluoroscopy.
• This low-voltage pulse serves as a proactive assessment tool, evaluating the proximity of the catheter to the phrenic nerve before any therapeutic application.
• The nine-electrode catheter in the PulseSelect system boasts fixed spacing, ensuring a consistent and predictable electric field for contiguous ablation. Beyond its primary function in ablation, these electrodes serve a multifaceted purpose, enabling both pacing and sensing functionalities.
• The streamlined 9Fr bidirectional catheter in the PulseSelect system significantly improves manoeuvrability, allowing easier access to diverse anatomical structures during procedures. Its compatibility with a 10Fr sheath, such as the specialised bidirectional FlexCath Contour™ sheath, ensures a seamless fit.

The approval of the PulseSelect PFA system marks a groundbreaking achievement as the first FDA breakthrough-designated PFA technology to be authorised for use.
