1. An ablation catheter comprising:
a catheter body having an outer diameter and defining a fluid delivery lumen, and
a deformable tip secured to the catheter body,
wherein the deformable tip (i) comprises one or more valves that are configured to open in response to inward deformation of the deformable tip upon contact with target tissue and (ii) has an inner diameter greater than the outer diameter of the catheter body, and
wherein the ablation catheter is configured to permit liquid communication between an interior of the deformable tip and an exterior of the deformable tip in response to a deformation of the tip.
