  • Patent number: 10702342
    Abstract: A method and system for determining a target location for a medical device having complex geometry relative to an anatomical feature, and for navigating and positioning the medical device at the target location. The system may include a medical device including a treatment element having a centroid, one or more navigation electrodes, and a longitudinal axis and a navigation system in communication with the one or more navigation electrodes, the navigation system including a processing unit. The processing unit may be programmed to define a plane that approximates a surface of the anatomical feature, define a centroid of the anatomical feature, define a vector that is normal to the plane and extends away from the centroid of the anatomical feature, and determine a target location for the treatment element of the medical device based on the vector to assist the user in placing the device for treatment.

  • Patent number: 10702213
    Abstract: A method and device for differentiating heart failure risk scores that includes determining receipt of a current data transmission and acquiring patient metrics from a remote monitoring device, determining a daily heart failure risk score for each day occurring during a time period from a previous received data transmission to the current received data transmission based on the acquired patient metrics, and determining a maximum daily heart failure risk score of the determined daily heart failure risk scores during a lookback window prior to the current received data transmission. A heart failure risk score is determined for the received data transmission based on the determined maximum daily heart failure risk score, and a heart failure risk score alert is determined for the received data transmission based on the proximity of the determined maximum heart failure risk score and the current received data transmission.

  • Patent number: 10695481
    Abstract: Systems and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system for performing kidney replacement therapy has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. The dialysis circuit and an extracorporeal circuit for circulating blood are in fluid communication through the dialysis membrane. The flux of fluid moving between the extracorporeal circuit and the dialysis circuit is modified by the rate at which the control pump is operating such that a rate of ultrafiltration and convective clearance can be controlled. The system provides for the monitoring of an inlet and outlet conductivity of the sorbent cartridge to provide a facility to quantify or monitor the removal of urea by the sorbent cartridge.

  • Patent number: 10688303
    Abstract: Target tissue sites for therapy delivery to a patient may be selected based on the patient symptoms or a patient mood state. The therapy delivery may be used to manage a psychiatric disorder of the patient. Selected therapy sites may be weighted based on factors, such as the severity of the patient symptom or mood state or the type of patient symptom or mood state. In some cases, therapy delivery to the patient may be controlled based on the weighting factors. For example, the weighting factors may control the intensity of the therapy delivery or the frequency of the therapy delivery. In some examples, the weighting factors may dynamically change based on the patient's changing symptoms or mood disorders.

  • Patent number: 10687843
    Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has a flexible body that allows the clearing tool to deflect when entering the epidural space through a window in the vertebral bone and ligaments. The clearing tool is guided into the epidural space and to a target site by a guidewire present in the epidural space. Upon removal of the guidewire and clearing tool, the medical lead is inserted through the window and cleared epidural space until reaching the target site. The clearing tool may include a distal tip with a shape and size that aids in the clearing of the epidural space. The distal tip may be integral to the clearing tool or may be removable so as to allow for different sizes of the distal tip to be installed as needed.

  • Patent number: 10682520
    Abstract: Devices, systems, and techniques for controlling charging power based on a cumulative thermal dose to a patient are disclosed. Implantable medical devices may include a rechargeable power source that can be transcutaneously charged. An external charging device may calculate an estimated cumulative thermal dose delivered to the patient during charging over a predetermined period of time. Based on the estimated cumulative thermal dose, the external charging device may select a power level for subsequent charging of the rechargeable power source. In one example, the charging device may select a high power level when the cumulative thermal dose has not exceeded a thermal dose threshold and select a low power level when the cumulative thermal dose has exceeded the thermal dose threshold.
