Provided herein are systems, methods and apparatuses for a medication adherence apparatus and methods of use. A method of adhering to medical prescription requirements combines sensors and hardware to record a cap state including an orientation, temperature, time stamp, and location of a cap device to enhance a patient's adherence to medical prescription when operably coupled with a computing device.

Medication adherence apparatus and methods of use

Cannula

A blood pump system includes two blood pumps, which may be implanted into a patient. The blood pumps may comprise VAD pumps. Control devices and methods operate the pumps such that they can function as a total artificial heart.

Artificial heart system

A physiologic control method and system for an implantable blood pump includes operating the pump at a predetermined speed and monitoring the patient's diastolic pump flow rate. The predetermined speed is varied in response to the diastolic pump flow rate. The pump speed may further be adjusted in response to the patient's heart rate. The speed may be increased and decreased in response to corresponding changes in the diastolic pump flow rate, and increased in response to an increase in heart rate.

Method and system for physiologic control of an implantable blood pump

A physiologic control system and method for controlling a blood pump system such as a VAD system. The pump system includes, for example, a blood pump and a controller for controlling the pump. The system may further include a flow measurement device. A desired peak to peak flow amplitude is determined, and then adjusted in response to various system parameters either manually or automatically by the system.

A blood flow calibration systemincluding a computeroperable to determine and store calibration data for a flow meter, a test systemoperable to simulate blood flow for the flow meter, thereby allowing the computerto determine the calibration data, and a programmeroperable to transfer the calibration data from the computerto the flow meter. The flow meterpreferably includes a power management circuitoperable to detect whether the flow meteris powered. In the event that the flow meteris unpowered, the power management circuitis preferably able to supply power to a portion of the flow meterin order to transfer the calibration data thereto.

A controller module for an implantable pump system which has a pump motor includes a processor, a motor controller electrically coupled to the processor and adapted to power the pump motor such that the pump motor operates at a desired speed. The motor controller outputs digital representations of the pump motor operating parameters to the processor. A first memory device is coupled to the processor for storing the digital signals representing the pump motor operating parameters. The controller module further includes a user interface. The controller module may be coupled to a data acquisition system, which provides power and exchanges data with the controller module. The controller module may alternately be coupled to a home support system which provides power for the controller module and storage for system components.

Method of controlling an implantable pump system

Implantable pump system

The present invention relates to a pulsatile flow system and method. The pulsatile flow system includes a reservoir, a pressure riser and a first fluid passage connected between the reservoir and the pressure riser. The system further includes a device adapted to expel fluid from the reservoir through the first fluid passage to the pressure riser. A second fluid passage is connected between the pressure riser and the reservoir, and is adapted to allow fluid to flow unidirectionally therethrough, from the pressure riser to the reservoir. The pulsatile flow system may be adapted to provide pulsatile fluid flow through a medical device, such as a ventricle assist device or mechanical heart valve, to replicate a heart's pumping action for testing the device.

Pulsatile flow system and method

A blood pump that comprises a pump housing having a blood flow path therethrough, a blood inlet, and a blood outlet; a stator mounted to the pump housing, the stator having a stator field winding for producing a stator magnetic field; a flow straightener located within the pump housing, and comprising a flow straightener hub and at least one flow straightener blade attached to the flow straightener hub; a rotor mounted within the pump housing for rotation in response to the stator magnetic field, the rotor comprising an inducer and an impeller; the inducer being located downstream of the flow straightener, and comprising an inducer hub and at least one inducer blade attached to the inducer hub; the impeller being located downstream of the inducer, and comprising an impeller hub and at least one impeller blade attached to the impeller hub; and preferably also comprising a diffuser downstream of the impeller, the diffuser comprising a diffuser hub and at least one diffuser blade. Blood flow stagnation and clot formation within the pump are minimized by, among other things, providing the inducer hub with a diameter greater than the diameter of the flow straightener hub; by optimizing the axial spacing between the flow straightener hub and the inducer hub, and between the impeller hub and the diffuser hub; by optimizing the inlet angle of the diffuser blades; and by providing fillets or curved transitions between the upstream end of the inducer hub and the shaft mounted therein, and between the impeller hub and the shaft mounted therein.

Rotary blood pump

A rotary blood pump includes a pump housing for receiving a flow straightener, a rotor mounted on rotor bearings and having an inducer portion and an impeller portion, and a diffuser. The entrance angle, outlet angle, axial and radial clearances of blades associated with the flow straightener, inducer portion, impeller portion and diffuser are optimized to minimize hemolysis while maintaining pump efficiency. The rotor bearing includes a bearing chamber that is filled with cross-linked blood or other bio-compatible material. A back emf integrated circuit regulates rotor operation and a microcomputer may be used to control one or more back emf integrated circuits. A plurality of magnets are disposed in each of a plurality of impeller blades with a small air gap. A stator may be axially adjusted on the pump housing to absorb bearing load and maximize pump efficiency.
