Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft with a plurality of electrodes coupled thereto and a processor coupled to the catheter shaft. The processor may be capable of collecting a set of signals from the plurality of electrodes and generating a data set from at least one of the set of signals. The data set may include at least one known data point and one or more unknown data points. The processor may also be capable of interpolating at least one of the unknown data points by conditioning the data set, assigning an interpolated value to at least one of the unknown data points, and assigning a confidence level to the interpolated value.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example method may include a method of identifying an activation time in a cardiac electrical signal. The method may include sensing a cardiac electrical signal, generating an approximation signal based at least in part on one or more parameters of the cardiac electrical signal, identifying a fiducial point on the approximation signal and determining, based at least in part on a timing of the fiducial point in the approximation signal, an activation time in the cardiac electrical signal.

Abstract: A catheter system includes a mapping catheter including a plurality of mapping electrodes, each mapping electrode configured to sense signals associated with an anatomical structure. The catheter system further includes a processor operatively coupled to the plurality of mapping electrodes and configured to receive the signals sensed by the plurality of mapping electrodes, characterize the signals sensed by the plurality of mapping electrodes based on a signal parameter of the sensed signals, and generate an output of a quality of contact of the plurality of mapping electrodes with the anatomical structure based on the signal characterization.
