    Abstract: 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.

    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example system for sensing tissue contact is disclosed. The system comprises a catheter shaft including a distal end portion. The distal end portion includes a sensing assembly having a plurality of electrodes. The plurality of electrodes includes a current-carrying electrode, a first sensing electrode and a second sensing electrode. The first sensing electrode is positioned a first distance from the current-carrying electrode. The second sensing electrode is positioned a second distance from the current-carrying electrode and the first distance is different from the second distance. The system also includes a controller coupled to the plurality of mapping electrodes. The controller is capable of calculating a parameter based at least in part on the first and the second distances.
