Abstract: Rotary microfluidic medical pump and pumping method embodiments are discussed herein that may be used for controlled delivery of small and precise volumes of therapeutic or non-therapeutic fluids in a variety of environmental conditions. Certain medical pump and pumping method embodiments discussed herein may also be useful for the controlled delivery of certain therapeutic fluids that may be susceptible to degradation when exposed to high levels of pressure, flow velocity, shear stress or the like. Training cartridge device and method embodiments discussed herein may be useful for familiarizing patients with the medical pump systems they are using.

Abstract: A computer-based system for monitoring the heart muscle function of a patient, with contextual oversight, includes a sensor array for collecting physiological and environmental data that are pertinent to the patient. A context register is also included which contains periodically updated patient-specific data that establishes a relevant contextual oversight capability for the system. In operation, a computer identifies anomalies in the physical data and detects aberrations in the environmental data. These anomalies and aberrations are then interactively evaluated together, relative to the contextual oversight capability, to determine whether clinical intervention for the patient is warranted.

Abstract: Systems and methods for monitoring a heart muscle function identify anomalies in the heart muscle function of a patient, relative to a predetermined cardio-profile. Concurrently, they also detect aberrations in the characteristics of perturbations that may have caused the anomaly. In detail, the aberrations are detected relative to a predetermined response matrix for the perturbation, and characteristics of the perturbation are weighted according to their potential influence on the anomaly. The anomalies that are identified from the cardio-profile are then evaluated relative to the corresponding perturbation aberration to determine whether clinical intervention is warranted.

Abstract: Subcutaneous access hub embodiments are discussed herein that include housing embodiments having a plurality of cannula ports and a fluid passageway network that allows fluid communication between a fluid source and the plurality of cannula access ports. Such a configuration may allow a user such as a patient or clinician to releasably secure the housing to an outside surface of the patient's skin. Multiple locations on the patient's skin may then be accessed for deployment of one or more delivery cannulas via a plurality of cannula ports for delivery of fluid and from the fluid source to multiple subcutaneous locations below the patient's skin and timely movement of cannula access in the patient's skin without the need for relocating the housing.

Abstract: Described herein is an orthopedic fixation device for use in spinal surgery. Said orthopedic device is a pivoting device that comprises one or more hinges. Fixation of multiple vertebrae is accomplished by fixation at the vertebral facet joints. Multiple device may be further fixed at multiple vertebral levels with the use of a multi-level rod.

Abstract: Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Abstract: Methods and devices for accurately pumping small quantities of liquid to a patient with a broad range of flow and low cost.

Abstract: The present invention pertains to methods for monitoring and evaluating a patient's heart muscle function. For the present invention this requires simultaneously detecting both cardiac signals (i.e. an EKG) and perturbation signals caused by the environmental and physical factors that are influencing the patient. In particular, when a cardiac signal is not compliant with a predetermined cardio-profile, an anomaly results. The resultant anomaly, and the perturbation causing the anomaly are then evaluated to determine whether an appropriate action is required.

Abstract: A system for monitoring and evaluating cardiac anomalies of a patient requires a cardiac sensor for detecting cardiac signals, and a perturbation sensor for detecting perturbations caused by stimuli that influence the cardiac signals. Based on normal cardiac signals for the patient, a cardio-profile is created which includes ranges of acceptable variations in selected parameters for the waveform of the cardiac signals. When a perturbation is detected by the perturbation sensor, its influence on the corresponding cardiac signal is evaluated relative to the cardio-profile to determine whether an anomaly has occurred. If so, the perturbation and the cardiac signal are further evaluated to determine whether a medical response is required.

Abstract: A novel enhanced flow metering device is adapted for disposing into a flow material reservoir a known volume of flow material whereby software used in conjunction with a pressure sensor may be calibrated. Additionally, by measuring the known amount of flow material returning to the flow material reservoir, checks are quickly made to ensure the pressure sensor is behaving as expected.
