Abstract: A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.

Abstract: Aspects of the disclosure include systems and devices for delivering an implant to a bodily annulus, such as an annuloplasty implant to a heart valve annulus. Various implants of the disclosure include one or more cinching lines extending through respective flexible tubular members, which are anchored to the annulus. The cinching lines can be tensioned to reshape the annulus. Systems further include least one lock to maintain the position of the cinching lines. Methods of reshaping the implant and locking a position of the reshaped implant are also disclosed.

Abstract: Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.

Abstract: Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.

Abstract: Devices, systems, and techniques are disclosed for determining an orientation of an implanted medical lead. For example, a system may include processing circuitry configured to receive image data representing a lead implanted within a patient, identify, from the image data, at least one hypointensive portion, identify, from the image data, at least one hyperintensive portion, determine, based on the at least one hypointensive portion and the at least one hyperintensive portion, an orientation of the lead within the patient, and output the orientation of the lead.

Abstract: A medical device includes an elongated body having a proximal end and a distal end and a braided tubular body extending coaxially with the elongated body between the proximal and distal ends. The braided tubular body includes multiple cables extending helically in opposing directions in an interwoven manner. Each cable includes multiple, electrically conductive filars. In some examples, each filar includes an electrically insulating coating or layer.

Abstract: An implantable medical device (IMD) includes a drug reservoir located within a reservoir chamber of the IMD that includes a first side and a second side directly opposite the first side defining a reservoir volume there between. The IMD further includes and a volume sensor system including an ultrasound transmitter within the reservoir chamber and positioned to transmit an ultrasound signal toward the second side at an angle relative to the second side and a plurality of ultrasound sensors adjacent to at least one of the first side or second side of the drug reservoir with each sensor positioned to selectively receive the signal from the transmitter at different reservoir volume levels to indicate a current volume capacity of the drug reservoir.
