摘要： Devices, systems, and techniques for monitoring the temperature of a device used to charge a rechargeable power source are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. The temperature of an external charging device and/or an implantable medical device may be monitored to control the temperature exposure to patient tissue during a charging session used to recharge the rechargeable power source. In one example, a temperature sensor may sense a temperature of an internal portion of a device, wherein the housing of the device is not directly thermally coupled to the temperature sensor. A temperature for the housing of the device may then be estimated based on the sensed temperature provided by the non-thermally coupled temperature sensor. A processor may then control charging of the rechargeable power source based on the determined temperature for the housing.

摘要： An implantable medical device (IMD) is described capable of determining whether a patient is susceptible to freezing of gait events during ambulatory movement without the patient demonstrating an episode of freezing of gait. In one example, the IMD senses, via one or more electrodes, a bioelectrical signal of a brain of the patient while the patient performs movement associated with freezing of gait. The IMD determines, based on the bioelectrical signal, whether the patient is susceptible to freezing of gait while the patient is not experiencing an episode of freezing of gait. Further, upon detecting the movement associated with freezing of gait, the IMD delivers electrical stimulation therapy to the patient configured to suppress freezing of gait.

摘要： An accessory controls power delivery from a host device to the accessory by receiving and rectifying a wireless signal into an electrical voltage that operates an electronic switch. The electronic switch sets a voltage state of an electrical connection to the host device that triggers the host device to begin providing power. The accessory may no longer receive power from the host device once the wireless signal stops. The host device may be the source of the wireless signal and may thereby control whether the accessory draws power by operation of the wireless signal. Alternatively, the accessory may include a controller that once powered on by the host device, maintains the same or a different electronic switch in a closed state to maintain power delivery from the host device until the controller is triggered to allow the electronic switch to open.

摘要： The present application concerns a medical device comprising a circuit configured to: receive a patient signal indicative of a patient condition; determine a timing signal having a frequency based on the patient signal; and during a duration when the patient signal is not being received, output the timing signal having the same frequency as the frequency of the timing signal determined based on the patient signal, the device also comprises an electrical stimulation generator configured to deliver therapy based on the timing signal during at least a portion of the duration when the patient signal is not being received. In some examples, a phase locked loop (PLL) circuit outputs a timing signal having a frequency and phase that is the same as a patient signal that is an input to the PLL circuit. The PLL circuit includes or is coupled to a storage circuit that stores information needed to cause the PLL circuit to maintain the frequency of the timing signal to the same frequency even after the patient signal is not available as an input.

The device further determines a reference rate value based on the received therapeutic agent concentration, wherein the reference rate value comprises a mass per unit of time. The device additionally displays a graphical user interface comprising a horizontal axis and a vertical axis, wherein the horizontal axis represents time and the vertical axis represents rates of delivery of the fluid by the implantable fluid delivery device. The maximum value of the vertical axis displayed in the graphical user interface is determined based on the determined reference rate value and is determined to be less than a maximum therapeutic agent infusion rate.
