US Patent 11751937 Ablation catheters and related systems and methods

An ablation catheter having a deformable tip is disclosed herein. In some implementations, the ablation catheter includes a catheter body and a deformable tip secured to the catheter body. In these and other implementations, the catheter body can include a fluid delivery lumen. In these and other implementations, the deformable tip includes one or more valves that are configured to open in response to deformation of the deformable tip. In these and still other implementations, the ablation catheter is configured to permit liquid communication between an interior of the deformable tip and an exterior of the deformable tip. In some implementations, RF energy is transmitted from the interior of the deformable tip to the exterior of the deformable tip via liquid exiting the deformable tip.
