Abstract: Systems, devices, and methods discussed herein can be for validating a position of a wirelessly powered electrostimulation device while the device is implanted in body tissue. A method can include situating the electrostimulation device in tissue and before an affixation mechanism of the electrostimulation device is deployed to maintain an implanted position of the electrostimulation device, and while electrodes of the device are in contact with the tissue, performing electrical testing of the electrostimulation device to determine whether the electrostimulation from the electrostimulation device evokes a specified response from the body that contains the tissue.

Abstract: Described herein are devices, systems, and methods for wireless power transfer utilizing a midfield source and implant. In one variation, a midfield source may be realized by a patterned metal plate composed of one of more subwavelength structures. These midfield sources may manipulate evanescent fields outside a material (e.g., tissue) to excite and control propagating fields inside the material (e.g., tissue) and thereby generate spatially confined and adaptive energy transport in the material (e.g., tissue). The energy may be received by an implanted device, which may be configured for one or more functions such as stimulation, sensing, or drug delivery.

Abstract: A pacing system computes optimal cardiac resynchronization pacing parameters using intrinsic conduction intervals. In various embodiments, values for atrio-ventricular delay intervals are each computed as a function of an intrinsic atrio-ventricular interval and a parameter reflective of an interventricular conduction delay. Examples of the parameter reflective of the interventricular conduction delay include QRS width and interval between right and left ventricular senses.

Abstract: A system and method for identifying patients with asynchronous ventricular contractions due to abnormal electro-mechanical coupling and computing optimal pacing parameters for restoring synchronous contractions is disclosed. Such patients may have normal intra-ventricular and inter-ventricular conduction and cannot be identified from intrinsic conduction data alone such as QRS width. Techniques for computing optimal resynchronization pacing in order to compensate for abnormal electro-mechanical coupling are also described.
