Patent
Rhythmia Medical | Date: 2016-10-31

This invention relates to the determination and/or representation of physiological information relating to a heart surface.


Patent
Rhythmia Medical | Date: 2016-12-04

Methods and systems for the determination and representation of anatomy anatomical information are disclosed herein.


Patent
Rhythmia Medical | Date: 2015-04-20

In general, in one aspect, a method is disclosed for determining information about a position of an object. The method includes: (i) causing current to flow between each of three or more sets of current-injecting electrodes on a first catheter inserted into an organ in a patients body, the organ having a periphery (ii) in response to current flow caused by each set of current injecting electrodes, measuring an electrical signal at each of one or more measuring electrodes located on one or more additional catheters inserted into the organ in the patients body and (iii) determining the position of each of one or more of the measuring electrodes on the additional catheters relative to the first catheter based on the measured signals from the one or more measuring electrodes.

Patent
Rhythmia Medical | Date: 2016-07-25

In some aspects, a method includes measuring unipolar signals at one or more electrodes in response to electrical activity in a heart cavity. The method also includes determining, based at least in part on Laplaces equation, bipolar physiological information at multiple locations of a surface based on the measured unipolar signals and positions of the one or more electrodes with respect to the surface.

Patent
Rhythmia Medical | Date: 2015-02-02

A non-contact cardiac mapping method is disclosed that includes: (i) inserting a catheter into a heart cavity having an endocardium surface, the catheter including multiple, spatially distributed electrodes; (ii) measuring signals at the catheter electrodes in response to electrical activity in the heart cavity with the catheter spaced from the endocardium surface; and (iii) determining physiological information at multiple locations of the endocardium surface based on the measured signals and positions of the electrodes with respect to the endocardium surface. Related systems and computer programs are also disclosed.
