摘要： An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector has a distal end and a proximal end with a longitudinal intermediate point between the distal and proximal ends. The end effector is sized to fit in an anatomical passageway within a cardiovascular system. The end effector includes at least one sensor electrode and a reference electrode. The at least one sensor electrode is configured to contact cardiovascular tissue and thereby pick up potentials. The reference electrode is configured to pick up a potential from fluid in contact with the reference electrode. The reference electrode is located proximal to the longitudinal intermediate point of the end effector. The end effector is configured to prevent the reference electrode from contacting tissue.

摘要： An electrophysiology catheter with a distal electrode assembly having covered spine carrying a plurality of microelectrodes. One or more spines have preformed configurations including at least a first portion with a first curvature and a second portion with a second curvature, and may include a linear portion. The linear portion may be between the first and second portions. The linear portion may be distal of the first and second portions. One or more spines have a narrower portion so that different portions of the spine can have different flexibility with a degree of independence in flexibility from adjacent portions.

摘要： This disclosure includes a hybrid electrode assembly mounted at the distal end of the catheter body having at least two spines and an inflatable balloon such that the inflatable balloon is disposed within the spines when in an expanded arrangement. The hybrid electrode assembly has a non-projecting distal portion when in the expanded arrangement.

摘要： An apparatus includes a catheter shaft assembly and an end effector. The catheter shaft assembly includes an outer sheath with a distal end. The end effector is associated with a distal end of the catheter shaft assembly. The end effector includes a plurality of leaflets. The leaflets are configured to transition between a first configuration and a second configuration. The leaflets are configured to fit within the outer sheath in the first configuration. The leaflets are configured to expand outwardly away from the longitudinal axis in the second configuration in response to being exposed distally relative to the distal end of the outer sheath. Each leaflet includes a flexible body and a plurality of electrodes. Each flexible body defines a plurality of openings. The electrodes are positioned on the flexible body.

摘要： An adapter can include circuitry that can toggle between a mapping state and an ablation state. In the mapping state the circuitry can connect the catheter to a mapping system so that the catheter can measure electrical signals from multiple independent electrodes on an end effector of the catheter. In the ablation state the circuitry can connect the catheter to an ablation generator so that the catheter can apply electrical signals to the electrodes to ablate using IRE and/or RF techniques. The circuitry can short together a group of electrodes in the ablation state and electrically isolate the electrodes in that group from each other when in the mapping state. Using the adapter, the catheter can ablate and map at a treatment site without having to be repositioned between the mapping and ablation steps.
