Abstract:
Techniques relate to operating a medical device by classifying a detected posture state of a patient. This classification may be performed by comparing the detected posture state of the patient to posture state definitions available within the system. Each definition may be described in terms of a parameter (e.g., vector) indicative of a direction in three-dimensional space. The posture state definitions may be calibrated by automatically estimating values for these parameters, thereby eliminating the need for the patient to assume each posture state during the calibration process to capture actual parameter values. According to another aspect, the estimated parameter values may be updated as the patient assumes various postures during a daily routine. For instance, estimated vectors initially used to calibrate the posture state definitions may be changed over time to more closely represent posture states the patient actually assumes, and to further adapt to changes in a patient's condition.
Abstract:
This disclosure is related to techniques for presenting therapy factors related to medical device therapy in a manner that allows a user, such as a patient or a clinician, to receive, comprehend and evaluate information relating to therapy delivered by the medical device efficiently. In one aspect, a method comprises obtaining a data set corresponding to a therapy factor associated with delivery of a medical therapy to a patient with a medical system including an implantable medical device, receiving a user selection associated with a subset of the data set, the subset of the data set including less than all the information relating to the therapy factor in the data set, and presenting a representation, corresponding to the subset of the data set, of the therapy factor on a display of a programmer.

Abstract:
This disclosure describes techniques for combining an image of a region defined by the user to receive stimulation therapy with an image of representation of leads which will deliver the therapy to the defined region, and importing the combined image on an implantable medical device connected to the leads that will deliver the stimulation therapy. During the process of combining the images, the user manipulates one or both of the images to combine the image such that the leads are placed for accurate therapy delivery. In some examples where more than one region is to receive stimulation therapy, each region can have a different image and/or a different set of leads associated therewith, and a combined image of each region may be produced, manipulated, and imported on the implantable medical device.
Abstract:
Methods and systems for monitoring and modifying pulsed field ablation (PFA) energy delivery to prevent patient safety risks and/or delivery device failure. In particular, some embodiments provide methods and systems for detecting and preventing arcs and arc-induced plasma, and their causal events, during delivery of pulsed field ablation energy, as well as methods and systems for identifying conditions leading to potential delivery device failure and correcting charge imbalance or asymmetry.
Abstract:
One or more efficacious electrode combinations for delivering electrical stimulation therapy to a patient may be selected based on the delivery of electrical stimulation to the patient via a predefined set of test electrode combinations in a predetermined order. In some examples, the electrode combinations of the set are arranged in the predetermined order such that adjacent electrode combinations in the order include at least one shared anode electrode or cathode electrode. In addition, the electrode combinations in the predetermined order may define a predetermined sequence of electrode patterns, each electrode pattern defining a relative arrangement between one or more anodes and one or more cathodes of the respective electrode pattern. In some examples, the transition between electrode combinations in the predefined set is achieved by incrementally adjusting at least one of anodic amplitudes assigned to active anode electrodes or cathodic amplitudes assigned to active cathode electrodes.
