An articulating motor stator assembly for use in a pump incorporates features that permit recycling of the motor stator when disposing of other parts of the pump. Such a stator assembly facilitates convenient manufacture, testing, and installation of the pump. For convenient installation, the motor stator assembly can incorporate a multi-part, annular housing that defines a central conduit to receive a motor rotor assembly. The multi-part housing of the motor stator assembly may be selectively repositioned between an open and closed configuration. In its open configuration a motor rotor assembly may be conveniently installed in the motor stator and when closed the motor stator will actuate the motor rotor assembly in order to operate a pump. The assembly thereby enables separate manufacture and shipment from a remote location. In addition, the assembly can be separately tested prior to installation.

A motor rotor assembly for use in a blood pump can include a motor rotor disposed within a blood flow conduit, an inflow bearing having an inflow ball-and-cup bearing interface disposed within the blood flow conduit proximal to an inflow port of the blood flow conduit, and an outflow bearing having an outflow ball-and-cup bearing interface disposed within the blood flow conduit proximal to an outflow port of the blood flow conduit. The motor can be rotatably mounted between the inflow bearing and the outflow bearing and an outer diameter of the outflow ball-and-cup bearing interface can be larger than an outer diameter of the inflow ball-and-cup bearing interface. A motor rotor assembly for use in a blood pump incorporating aspects of the invention may improve performance, reliability and longevity of the pump. A blood pump incorporating a motor rotor can further include a motor stator. These rotors and pumps can be used in both implantable and extracorporeal blood pumps.

An apparatus and method for monitoring the energy, such as acoustic energy, generated by the translational (or "snapping") movement of tendons across the carpal tunnel, whereby an energy signature for such movement can be recognized. Feedback can then be provided to or about the person being monitored to permit, encourage, or force that person to choose a different movement whereby detrimental translational movement of tendons is reduced or minimized. Such reductions may result in a lower occurrence of CTS or the avoidance of its deleterious effects.

A Braille mouse uses a character-code carrying member such as a disc, belt or drum to selectively raise Braille pins with a single solenoid. The Braille pins are provided with eccentric fingers which interact with a character-code carrying member, so that the character codes can be arranged in straight radial lines to allow all possible six-pin Braille symbols to be provided on a member of minimum size.

The invention provides an axial flow blood pump with slanting outflow components. Specifically, the invention provides a blood pump having an angling outer stator blade edge structure in combination with a blood flow conduit having a constricting inner diameter. After constricting, the blood flow conduit can expand such that the inner diameter of the conduit increases. In addition, the blood pump can have an angling inner stator blade edge structure and a tapering stator blade hub or tapering rotor element.

An axial-flow blood pump has a rotor suspended in ball-and-cup bearings which are blood-cooled but not actively blood-lubricated. The ball-and-cup structures are made of highly heat-conductive material and are in heat-transferring contact with heat-conductive stator blades that serve as heat sinks for the bearings. The ball-and-cup structures are radially much smaller than the stator blades. The ball-and-cup interface has so small a gap that the ball-to-cup structures present an essentially continuous surface to the blood flow.

An implantable electric blood pump has a motor stator defining a cylindrical blood conduit, and a pump rotor in which the motor rotor is embedded. The pump rotor is conical at each of its ends and terminates at each end in a ball-and-cup structure washed directly by the pumped blood stream. Grooves may be formed in the ball-and-cup structure to enhance the heat-removing washing action of the blood stream. The pump rotor is nested in the stator blades to shorten the pump and wash the outlet bearing with a partially circumferential blood flow. Titanium-titanium carbide facing alumina are the preferred materials for the rotary-stationary interface, and the gap of the rotary-stationary interface is kept so small that no significant amount of blood serum can penetrate between the mating surfaces of the interface.

A centrifugal blood pump features a pump assembly including a cylindrical barrel insertable into a motor stator. The barrel contains a motor rotor which is directly coupled to the pump's impeller. The barrel can be oriented and locked in the motor stator in many different angular orientations. Hemolysis is prevented in spite of high speed operation by reducing the clearance between the impeller and the impeller chamber, rounding the edges of the impeller blades, and providing a deflector to prevent blood from being impelled more than once around the impeller chamber periphery. An efficient releasable locking mechanism is also disclosed, as is a preferred method of assembling the pump assembly with close tolerances.

An inline electrical connector includes a first housing shell and a second housing shell. The first housing shell has a cable entrance section and a planar mating section that includes a plurality of electrical connectors. The second housing shell also has a cable entrance section and a planar mating section that has a plurality of electrical connectors. The second housing shell can be mated with the first housing shell by overlapping engagement of the planar mating sections. The electrical connectors on the first housing shell are configured to mate with the electrical connectors on the second housing shell when the second housing shell is mated with the first housing shell.
