A blood flow assist system can include an impeller assembly including an impeller shaft and an impeller on the impeller shaft, a primary flow pathway disposed along an exterior surface of the impeller. The system can include a rotor assembly at a proximal portion of the impeller shaft. A secondary flow pathway can be disposed along a lumen of the impeller shaft. During operation of the blood flow assist system, blood can be pumped proximally along the primary flow pathway and the secondary flow pathway. The system can include a sleeve bearing distal the impeller. The system can include a drive unit having a distal end disposed distal a proximal end of the second impeller. The drive unit comprising a drive magnet and a drive bearing between the drive magnet and the impeller assembly.

Blood pumps

An improved system for supporting (e.g., localization and/or positioning of) intravascular devices discussed herein provides for example a multi-element arrangement. A set of struts optionally projects from the intravascular device and contacts the vessel walls. The localization and positioning of the pump may be provided by the struts and/or by use of a tether opposing a propulsive force to ensure localization.

Support structures for intravascular blood pumps

Systems and methods for providing a magnetic fluid (MF) seal suitable for a fluid environment may provide a shaft and a magnet that is cylindrical or ring-shaped. A magnetic fluid may be present between the magnet and shaft. Additionally, pole pieces may also be provided, which are also cylindrical or ring-shaped. These pole pieces are positioned on the shaft so the magnet is sandwiched between the pole pieces. The magnet, pole pieces, and shaft, if magnetic, may attract and retain the magnetic fluid in an annular gap or region between the shaft and the magnet and/or the pole pieces. The magnetic fluid in the annular gap serves as a seal or barrier that prevents fluid from passing through when pressure is below a predetermined level.

Magnetic fluid seal for implantable devices

An external, head worn electrical nerve stimulation device is disclosed that includes a head band including inner and outer surfaces, and a plurality of holes each including an interior surface. The device also includes a plurality of mounting baskets disposed within the holes and each including a cylindrical retaining member, and a plurality of biasing arms extending from the interior surface to the retaining member. The biasing arms are to bias the retaining member toward the inner surface, and the head band, the retaining members, and the biasing arms are all monolithically formed as a single piece. Further, the device includes a plurality of electrodes, disposed within the retaining members and biased into engagement with a patient's head. The plurality of electrodes is configured to stimulate, at least one of the greater occipital nerve, the lesser occipital nerve, the supraorbital nerve, the supratrochlear nerve, zygomatotemporal nerve, and the auriculotemporal nerve.

External, head-worn electrical stimulator for treating headache conditions

An external, head worn electrical nerve stimulation device, including a power source and a head band configured to fit around a patient's head, the patient's head including a front portion, a rear portion opposite the front portion, a first lateral side, and a second lateral side opposite the first lateral side. The device further includes a plurality of electrical electrodes circumferentially disposed along the head band, wherein the plurality of electrodes contacts each of the front portion, the rear portion, the first lateral side, and the second lateral side. The plurality of electrical electrodes is configured to stimulate, with electrical current, at least one of the greater occipital nerve, the lesser occipital nerve, the supraorbital nerve, the supratrochlear nerve, zygomatotemporal nerve, and the auriculotemporal nerve when the electrodes are energized by the power source.
