Medical devices and methods for making and using medical devices are disclosed. An example electrophysiology medical device may include a catheter shaft including a distal end portion and a sensing assembly having three or more terminals. The sensing assembly includes one or more current-carrying electrodes and one or more sensing electrodes. The one or more current-carrying electrodes, the one or more sensing electrodes, or both includes a mini-electrode. The mini-electrode is disposed on one of the other electrodes. The medical device may also include a controller coupled to the sensing assembly.

Tissue diagnosis and treatment using mini-electrodes

A system and method for voltage-guided anatomical shell editing includes outputting, to a display device, an anatomical shell of a cardiac structure. The anatomical shell is based on signals sensed by a mapping probe, each signal including a respective sensed voltage. User input specifying a first target depth for editing is received, as is a selection of a first region of the anatomical shell. A modified anatomical shell is generated by removing a first portion of the anatomical shell including the selected first region to a first editing depth based on the first target depth and generating a new surface region on the modified anatomical shell. Based on the voltage associated with the new surface region, the edit can be maintained, undone, and/or modified.
