Some examples of the disclosure include applications, treatment-monitoring systems and computing devices configured with the applications, and computer-implemented methods to aid user monitoring of disordered-breathing and treatment.

Systems, devices and methods are provided for administering a carrier incorporating a therapeutic preparation within a subject. A device includes a carrier, and a launch assembly to deploy the carrier by ejecting the carrier from the device and into internal tissue of the subject. The device detects a status of deployment of the carrier. A system includes a delivery device, a carrier disposed in the delivery device, a launch assembly, and detection circuitry. The launch assembly causes the carrier to exit the delivery device so as to penetrate internal tissue of the subject. The system determines a status of deployment of the carrier using the detection circuitry. A method includes introducing a launch assembly within the subject, the launch assembly coupled to a carrier; deploying, by the launch assembly, the carrier; and detecting a status of deployment of the carrier.

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.

An injector for transcutaneously introducing a sensor into a patient, including a cannula, a sensor arranged in the cannula, a base element, a sliding element arranged displaceably on the base element in an injection direction, for transcutaneously introducing the cannula having the sensor into the patient in an injection operation. The cannula has a slot in a longitudinal direction of the cannula. The injector has a holding element arranged displaceably on the base element that, in an ejection operation, prevents the sensor from being pulled out as the cannula is withdrawn, by engaging in a distal end region of the sensor through the slot into the cannula. The holding element and/or base element have at least one fixing arrangement to automatically lock the holding element on the base element when the cannula is introduced transcutaneously into the patient. A method for transcutaneously introducing a sensor into a patient is also provided.

Implantable ports used for intravenous administration and methods of using the same.

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 implantable emergency management drug delivery system configured to deliver a medicament to reverse the effects of a drug overdose. The implantable emergency management drug delivery system including an implantable infusion pump configured to infuse a first medicament, and an emergency handling device having at least one physiological sensor configured to monitor a condition of a patient for a possibility of an overdose from the first medicament, a communication module configured to communicate the possibility of an overdose to the implantable infusion pump, and an implantable medicament delivery mechanism configured to deliver a second medicament to reduce one or more adverse physiological effects of the first medicament.

A ventricular assist device includes a stent for placement within a cardiac artery and arranged for placement, the stent arranged to have an open configuration defining a flow path, a rotor sized to fit within the stent and arranged for percutaneous placement the flow path, the rotor including a surface disposed about a central portion and angled with respect to the flow path and having a first plurality of magnets. A collar is sized for placement about the cardiac artery and includes a stator. A power source is coupled to the stator, and the stator and the rotor are arranged to rotate the rotor about an axis. A timing control module controls a rotational speed of the rotor. Accordingly, the surface of the rotor is arranged to move blood along the flow path in response to rotation of the rotor.

A medicament delivery system configured to reduce the risk of inadvertently injecting medicament directly into a patient during a refill procedure via an external refilling apparatus. The medicament delivery system may include an implantable medical pump having a refillable medicament reservoir accessible via an access port, wherein the refillable medicament reservoir includes a flexible diaphragm having a nonlinear spring rate configured to create a relative vacuum within a medicament chamber when medicament is expelled from the medicament chamber beyond a predefined threshold, so as to spontaneously draw a quantity of medicament into the medicament chamber during the refill procedure to reestablish the predefined threshold, thereby confirming proper placement of a portion of the external refilling apparatus into the access port.

The present invention generally relates to heart treatment systems. In some aspects, methods and systems are provided for facilitating communication between implanted devices. For example, an implantable cardiac rhythm management device may be configured to communicate with an implantable blood pump. The implantable cardiac rhythm management device may deliver heart stimulation rate information in addition to information associated with any detected abnormalities in heart function. In response, the pump may be configured to adjust pumping by the pump to better accommodate a patient's particular needs.
