The invention includes an elongate body with a distal electrode, expandable members between the electrode and body distal end, an actuator for advancing and retracting the electrode, and a fluid-sealed lumen configured to expand and collapse with electrode movement. The patent contains 17 claims and covers catheters with improved irrigation capabilities for medical procedures.
What changed
USPTO issued Patent US12599431B2 to Sirona Medical Technologies, Inc. covering catheters with improved irrigation featuring expandable and contractible fluid pathways. The patent protects an elongate body with a distal electrode, expandable members or wings, an actuator for advancing and retracting the electrode, and a fluid-sealed lumen that can expand and collapse while remaining fluidly separated from the actuator. The 17-claim patent names inventors Ali Haghighi-Mood and Richard Jonathan Cohen.
For manufacturers and medical device companies, this patent establishes intellectual property rights that may affect product development strategies and freedom-to-operate analyses.

Abstract
Various catheters with expandable and contractible fluid pathways extending therethrough, and methods of use, are provided herein. In an exemplary embodiment, a catheter is provided with an elongate body having an electrode at the distal end thereof. One or more expandable members or wings can extend between the electrode and the distal end of the elongate body. The catheter can also include an actuator extending therethrough and coupled to the electrode such that movement of the actuator is effective to advance and retract the electrode, thereby moving the one or more expandable members between a collapsed configuration and an expanded configuration. The catheter can also include a fluid sealed lumen formed therein and configured to receive fluid and to deliver fluid to one or more pathways formed in the electrode. The actuator can extend through the fluid sealed lumen, however it can be fluidly separated from the lumen. The fluid sealed lumen can be configured to expand and collapse with movement of the electrode, while allowing movement of the actuator therethrough.
