Abstract
A system and method to target a biological rhythm disorder, such as a heart rhythm disorder, include processing cardiac signals via a computing device to determine a shape in a region of tissue defined by a source associated with the biological rhythm disorder that migrates spatially on or within the shape, and identifying at least one portion of the tissue proximate to the shape to enable selective modification of the at least one portion of tissue in order to terminate or alter the heart rhythm disorder.
Claims46
A method of targeting a cardiac rhythm disorder, the method comprising:
- processing cardiac signals associated with the cardiac rhythm disorder to track a path of migration of a source associated with the cardiac rhythm disorder over multiple periods of time;
- determining a shape in a region of tissue defined by the path of migration of the source, the source migrating spatially on or within the shape;
- identifying at least one portion of the tissue proximate to the shape;
- and
- selectively modifying the at least one portion of the tissue in order to terminate or alter the cardiac rhythm disorder.
A system to target a cardiac rhythm disorder, the system comprising:
- at least one processing device configured to:
- process cardiac signals associated with the cardiac rhythm disorder to track a path of migration of a source associated with the cardiac rhythm disorder over multiple periods of time;
- determine a shape in a region of tissue defined by the path of migration of the source, the source migrating spatially on or within the shape;
- and
- identify at least one portion of the tissue proximate to the shape;
- and
- a device configured to selectively modify the at least one portion of the tissue in order to terminate or alter the cardiac rhythm disorder.
A system for targeting a cardiac rhythm disorder, the system comprising:
- a processing device;
- a memory comprising instructions that, when executed by the processing device, cause the processing device to:
- process cardiac signals associated with the cardiac rhythm disorder to track a path of migration of a source associated with the cardiac rhythm disorder over multiple periods of time;
- determine a shape in a region of tissue defined by the path of migration of the source, the source migrating spatially on or within the shape;
- and
- identify at least one portion of the tissue proximate to the shape;
- and
- a device configured to selectively modify the at least one portion of the tissue in order to terminate or alter the cardiac rhythm disorder.
A method of targeting a biological rhythm disorder, the method comprising:
- receiving signals in a processing device over a network, the signals associated with a biological rhythm disorder of an organ;
- processing the signals to track a path of migration of a source associated with the biological rhythm disorder over multiple periods of time;
- processing the signals to determine a shape in a region of tissue defined by the path of migration of the source, the source migrating spatially on or within the shape;
- identifying at least one portion of the tissue proximate to the shape for targeted modification of the at least one portion of the tissue;
- and
- transmitting data from the processing device to a second processing device over the network, the data indicating at least one of the shape and the at least one portion of the tissue proximate to the shape;
- and
- selectively modifying the at least one portion of the tissue in order to terminate or alter the biological rhythm disorder.
