Abstract
A catheter system includes a mapping catheter having a plurality of splines, each of the plurality of splines including a plurality of mapping electrodes. The system further includes a processor operatively coupled to the plurality of mapping electrodes and configured to receive signals sensed by the plurality of mapping electrodes. The processor is further configured to estimate an interspline distance between adjacent splines in the plurality of splines based on the signals sensed by the mapping electrodes on the adjacent splines.

A catheter system comprising:
- a mapping catheter including a plurality of splines, each of the plurality of splines including a plurality of mapping electrodes;
- a processor operatively coupled to the plurality of mapping electrodes and configured to receive signals sensed by the plurality of mapping electrodes, the processor further configured to estimate an interspline distance between adjacent splines in the plurality of splines based on the signals sensed by the mapping electrodes on the adjacent splines.
A method for estimating interspline distances on a mapping catheter including a plurality of splines, each of the plurality of splines including a plurality of mapping electrodes, the method comprising:
- measuring a parameter between a first pair of mapping electrodes among the plurality of mapping electrodes;
- measuring the parameter between a second pair of mapping electrodes among the plurality of mapping electrodes;
- and
- determining the interspline distances based on a comparison of the parameter measured by the first pair of mapping electrodes with the parameter measured by the second pair of mapping electrodes.
A method for displaying a mapping catheter in a mapping system, the mapping catheter including a plurality of splines, each of the plurality of splines including a plurality of mapping electrodes, the method comprising:
- positioning the plurality of mapping electrodes proximate to an anatomical structure;
- sensing signals with the plurality of mapping electrodes;
- estimating an interspline distance between adjacent splines in the plurality of splines based on the signals sensed by the mapping electrodes on the adjacent splines;
- and
- displaying a representation of the mapping catheter according to the estimated interspline distances.
