A heart pump including a housing defining a cavity including at least one inlet aligned with an axis of the cavity and at least one outlet provided in a circumferential outer wall of the cavity. An impeller is provided within the cavity, the impeller including a rotor and vanes mounted on the rotor for urging fluid from the inlet radially outwardly to the outlet. A drive is provided for rotating the impeller in the cavity, the drive including a plurality of circumferentially spaced permanent drive magnets mounted within and proximate a first face of the rotor, adjacent drive magnets having opposing polarities and a plurality of circumferentially spaced drive coils mounted within the housing proximate a first end of the cavity, each coil being wound on a respective drive stator pole of a drive stator and being substantially radially aligned with the drive magnets, the drive coils being configured to generate a drive magnetic field that cooperates with the drive magnets to thereby rotate the impeller. A magnetic bearing is also provided to thereby at least one of control an axial position of the impeller and at least partially restrain radial movement of the impeller.

Hemofilter For In Vivo Blood Filtration

Hemofilters for in vivo filtration of blood are disclosed. The hemofilters disclosed herein provide an optimal flow of blood through the filtration channels while maintaining a pressure gradient across the filtration channel walls to enhance filtration and minimize turbulence and stagnation of blood in the hemofilter.

Injected conductive tattoos for powering implants

The present disclosure describes aspects of injected conductive tattoos for powering implants. In some aspects, a system comprises a conductive tattoo used to efficiently transfer power wirelessly received from a transmitter outside a body to an electronic device in the body. The conductive tattoo is formed from a conductive material injected into an outermost permanent layer of the body. The conductive tattoo is configured to wirelessly receive and relay the power from the transmitter to the electronic device. In particular, the conductive tattoo may transfer the power to the electronic device over a coupling between the conductive tattoo and the electronic device.

Bioartificial ultrafiltration device and methods related thereto

Bioartificial ultrafiltration devices comprising a scaffold comprising a population of cells enclosed in a matrix and disposed adjacent a plurality of channels are provided. The population of cells provides molecules such as therapeutic molecules to a subject in need thereof and is supported by the nutrients filtered in an ultrafiltrate from the blood of the subject. The plurality of channels in the scaffold facilitate the transportation of the ultrafiltrate and exchange of molecules between the ultrafiltrate and the population of cells.

Adhesive and peripheral systems and methods for medical devices

Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.
