Catheter for pulsed field ablation with multiple electrodes
A recently filed patent (Publication Number: US20230310068A1) describes a catheter designed for pulsed field ablation (PFA). The catheter includes an elongated structure with multiple electrodes positioned on its distal portion. These electrodes consist of a tip electrode, a tip ring electrode adjacent to the tip electrode, a pair of ring electrodes, and one or more additional electrodes. The pair of ring electrodes is longitudinally placed between the tip ring electrode and the additional electrodes.
The patent also mentions that the distance between the electrodes of the pair of ring electrodes is smaller than the distance between the distal ring electrode of the pair and the tip ring electrode. This configuration allows for precise control and delivery of electrical stimulation during PFA procedures.
The catheter further includes control leads for the electrodes. A first common control lead is connected to both the tip electrode and the tip ring electrode, while a second common control lead is connected to both electrodes of the pair of ring electrodes. Additionally, there is a separate control lead for each electrode of the catheter's electrode array.
The patent also discusses variations of the catheter design. For example, the additional electrodes can include a coil electrode or one or more additional pairs of ring electrodes. In one embodiment, the catheter includes both a coil electrode and additional pairs of ring electrodes, which are placed longitudinally between the coil electrode and the pair of ring electrodes.
The patent application also describes a system that includes the catheter and a controller for controlling the delivery of electrical stimulation during PFA procedures.
Overall, this patent application presents a catheter design specifically tailored for pulsed field ablation. The configuration of the electrodes and control leads allows for precise and controlled electrical stimulation, making it a potentially valuable tool for medical professionals performing PFA procedures.
