Disclosed is s self-cleaning catheter system with self-monitoring capabilities. The catheter system includes a catheter configured to be implanted in a body cavity of a subject, a cleaning unit configured for motion within the catheter such as to mechanically prevent and/or remove or mitigate blockage of at least a section of the catheter, an implantable sensor, and an implantable controller functionally associated with the cleaning unit and configured for activation thereof. The implantable sensor is communicatively associated with the implantable controller and is configured to detect motion of the cleaning unit, and to output one or more signals indicative of the motion of the cleaning unit. The implantable controller is configured to receive the one or more signals from the implantable sensor and, based, at least, thereon, to provide at least one motion indication, at least when the one or more signals are indicative of malfunctioning of the cleaning unit.

An example system for therapy delivery includes one or more processors configured to in response to a prediction indicating that the meal event is to occur, output instructions to an insulin delivery device to deliver a partial therapy dosage, to a device to notify the patient to use the insulin delivery device to take the partial therapy dosage, or to the insulin delivery device to prepare the partial therapy dosage prior to the meal event occurring, and in response to a determination indicating that the meal event is occurring (e.g., based on movement characteristics of a patient arm), output instructions to the insulin delivery device to deliver a remaining therapy dosage, to the device to notify the patient to use the insulin delivery device to take the remaining therapy dosage, or to the insulin delivery device to prepare the remaining therapy dosage.

Devices, systems, and techniques for controlling delivery of therapy for diabetes are described. In one example, a system includes a wearable device configured to generate user activity data associated with an arm of a user; and one or more processors configured to: identify at least one gesture indicative of utilization of an injection device for preparation of an insulin injection based on the user activity data; based on the at least one identified gesture, generate information indicative of at least one of an amount or type of insulin dosage in the insulin injection by the injection device; compare the generated information to a criteria of a proper insulin injection; and output information indicative of whether the criteria is satisfied based on the comparison.

One or more processors may be configured to detect whether a patient with diabetes is operating a vehicle based on one or more detected gestures. Based on the detection of operating the vehicle, the one or more processors may cause a patient device to output alerts according to a driving alert protocol. In another example, based on the detection of operating the vehicle, one or more processors may cause an insulin pump to operate according to a driving therapy protocol.

Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.

An electrode guide device is described for inserting a cochlear implant electrode array into a scala tympany of a patient cochlea has an electrode guide tube and an end positioner at least partially contained within a cavity of the guide tube at the distal end and slidable within the cavity for adjustable extension beyond the distal end. The end positioner has a natural curvature that is constrained by the cavity of the guide tube for any portion contained within the cavity of the guide tube, and any portion of the end positioner extended beyond the distal end follows the natural curvature. The electrode array can be introduced through the groove of the guide tube along a first directional line towards an electrode opening in the patient cochlea, and then the distal end of electrode array emerging from the guide tube is redirected by the extension of the end positioner along a different second directional line through the electrode opening.

The invention generally relates to heart pump systems. In some embodiments, a pressure sensor is provided with a heart pump, either at the inflow or the outflow of the blood pump. The heart pump may further include a flow estimator based on a rotor drive current signal delivered to the rotor. Based on the rotor drive current signal, a differential pressure across the pump may be calculated. The differential pressure in combination with the pressure measurements from the pressure sensor may be used to calculate pressure on the opposite side of the pump from the pressure sensor. In some embodiments, the pressure sensor is located at the outflow of the pump and the pump is coupled with the left ventricle. The differential pressure and pressure measurement may be used to calculate a left ventricular pressure waveform of the patient. With such a measurement, other physiological parameters may be derived.

A mechanical circulatory assist system includes a continuous-flow pump and a controller. The pump is implantable to assist blood flow from the left ventricle to the aorta The controller is operable to control a rotation speed of the pump over an operational cycle. The operational cycle includes a first segment over which the ventricular assist device is operated at first rotation speed, a second segment over which the rotation speed of the ventricular assist device is decreased from the first rotation speed to a second rotation speed, a third segment over which the ventricular assist device is operated at the second rotation speed, and a fourth segment over which the rotation speed of the ventricular assist device is increased from the second rotation speed. A contraction of the left ventricle that opens and closes the native aortic valve occurs during the third segment.

The disclosure describes systems and techniques for detection of pump thrombosis in mechanical circulatory support (MCS) devices. An example pump thrombosis detection system includes a transducer and processing circuitry. The transducer may be configured to generate a signal representative of a mechanical wave from a mechanical circulatory support device. The processing circuitry is communicatively coupled to the transducer. The processing circuitry may be configured to determine an indication of pump thrombosis based on the signal and, based on the indication of pump thrombosis, control the pump thrombosis detection system to at least one of generate an alert or initiate an intervention.
