Abstract
Devices, systems, and methods for treating cardiac arrhythmia are disclosed herein. In some embodiments, devices, systems, and methods disclosed herein deliver interrogating energy to tissue at a position on a wall of an anatomical structure of a patient. If the devices, systems, and methods disclosed herein detect a change in electrical activity of the anatomical structure in response to the interrogating energy, the devices, systems, and methods disclosed herein can apply irreversible therapy to the tissue. In some embodiments, the change in electrical activity corresponds to slowing or termination of a detected arrhythmia.
Claims22
A method, comprising:
- delivering first energy to first target tissue of an anatomical structure of a patient via an electrode carried by a catheter;
- measuring electrical activity of the anatomical structure after delivering the first energy;
- analyzing the measured electrical activity to detect a change in an arrhythmia caused by the first energy;
- displaying a first therapy annotation in a three-dimensional model of the anatomical structure at a location in the model corresponding to a location of a tip section of the catheter in the anatomical structure when the first energy was delivered to the first target tissue, wherein the first therapy annotation includes a first set of visual properties, and wherein one or more visual properties of the first set are updated dynamically as a function of time to indicate whether the first energy delivered to the first target tissue slowed or terminated the arrhythmia based on the detected change in the arrhythmia and to indicate a predicted extent of recovery of electrical activity of the first target tissue at a given time after delivering the first energy;
- delivering second energy to second target tissue of the anatomical structure via the electrode of the catheter, wherein the second target tissue at least partially overlaps with the first target tissue;
- and
- after delivering the second energy, displaying a second therapy annotation in the three-dimensional model of the anatomical structure corresponding to delivery of the second energy to the second target tissue.
A method comprising:
- delivering reversible energy to target tissue of an anatomical structure of a patient via an electrode carried by a catheter, wherein the reversible energy temporarily alters electrical activity of the target tissue;
- displaying a therapy annotation in a three-dimensional model of the anatomical structure at a location in the model corresponding to a location of a tip section of the catheter in the anatomical structure when the reversible energy was delivered to the target tissue, wherein the therapy annotation includes one or more visual properties;
- and
- changing at least one of the one or more visual properties of the therapy annotation as a function of time, wherein the at least one visual property is indicative of a predicted extent of recovery of the electrical activity of the target tissue at a given time after delivering the reversible energy to the target tissue.
