Medical devices for mapping cardiac tissue
First Claim
1. A system for mapping electrical activity of a targeted cardiac tissue region in a body, the system comprising:
- a catheter comprising a distal end including a multiple electrode structure, the multiple electrode structure configured to sense a plurality of signals generated by the cardiac tissue over a period of time;
a processor electrically coupled to the multiple electrode structure, the processing being configured to;
receive the plurality of signals;
determine propagation angles for the plurality of signals, the propagation angles including at least one propagation angle exceeding a threshold level of randomness;
generate data sets for each electrode of the multiple electrode structure, wherein the data sets are based on the plurality of signals sensed by the multiple electrode structure and include the determined propagation angles for the plurality of signals; and
generate a propagation map using the generated data sets, the propagation map including a visual indicator corresponding to the at least one propagation angle exceeding the threshold level of randomness.

Abstract
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.
