20150342488 | MEDICAL DEVICES FOR MAPPING CARDIAC TISSUE - 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. | 12-03-2015 |
20150351652 | ELECTRODE ASSEMBLY - An expandable electrode assembly for use in a cardiac mapping procedure includes multiple bipolar electrode pairs including a first electrode located on an outer surface and a second electrode located on an inner surface of the individual splines forming the expandable electrode assembly. Such an electrode arrangement may produce improved electrical activation signals which may be used to produce a more accurate map of the electrical activity of a patient's heart. | 12-10-2015 |
20150366476 | MEDICAL DEVICES FOR MAPPING CARDIAC TISSUE - Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a system for mapping the electrical activity of the heart. The system may include a catheter shaft with a plurality of electrodes. The system may also include a processor. The processor may be capable of collecting a set of signals from at least one of the plurality of electrodes. The set of signals may be collected over a time period. The processor may also be capable of calculating at least one propagation vector from the set of signals, generating a data set from the at least one propagation vector, generating a statistical distribution of the data set and generating a visual representation of the statistical distribution. | 12-24-2015 |
