A blood pump () includes a stator assembly comprising a motor stator (), a fluid inlet (), and a fluid outlet (). A rotor assembly includes a motor rotor () and an impeller () rotatable about an axis () to move fluid from the inlet () to the outlet (). An outflow sheath () directs the flow along the outside of the pump ().

Blood pump

A portable liquid drug delivery device has a reservoir part and a driving part, and the driving part has a drive that produces a torque. The reservoir part has a reservoir that retains liquid drug and an outlet port is in fluid communication with the reservoir. An engagement member has an inner thread that engages the thread of a piston rod in an engaged position and is disengaged from the thread of the piston rod in a disengaged position. The engagement member is prestressed in the disengaged position to thereby bias the engagement member toward the engaged position. The engagement member only converts the torque of the drive into a linear movement of the piston rod when the engagement member is in the engaged position. The piston is configured, upon the linear movement of the piston rod, to deliver the liquid drug to the outlet port.

Portable liquid drug delivery device

A blood pump () includes a stator assembly () that includes a motor stator, a fluid inlet (), and a fluid outlet (). A rotor assembly () includes a motor rotor () and an impeller () rotatable about an axis () to move fluid from the inlet () to the outlet (). A permanent magnet radial bearing () supports the rotor assembly for rotation about the axis (). The radial bearing () includes a permanent magnet radial bearing stator () fixed to the stator assembly () and a permanent magnet radial bearing rotor () fixed to the rotor assembly (). The radial bearing () is configured such that the radial bearing stator magnets () and the radial bearing rotor magnets () are axially offset from each other when the pump is at rest.

A substantially flexible implant holder for holding a substantially tubular implant structure during fatigue testing of the implant structure, the implant holder having a substantially elongate cavity for occupation by the tubular implant structure and a cavity-surrounding part which extends from at least a first longitudinal end of the cavity to at least a second longitudinal end of the cavity, the cavity-surrounding part having a stiffness which gradually changes from a relatively high stiffness adjacent each of the longitudinal ends of the cavity to a relatively low stiffness adjacent a middle portion which is situated between the two longitudinal ends of the cavity.

Substantially flexible implant holder for a tubular implant structure

A fatigue test system for repetitively deforming a substantially tubular implant structure which is within a radial range and within an axial range expandable and contractable and which has at least a first and a second end, wherein the system comprises at least a first and second part which are controllably moveable relative to each other, and a first and a second fixture assembly for fixing the first end to the first part and the second end to the second part, so that the system controls in use the position of each of the first and second end of the tubular implant structure.

Fatigue test system and method of testing of tubular implant structures

A blood pump () includes a stator assembly including a fluid inlet () and a fluid outlet (). A rotor assembly () includes an impeller () rotatable about an axis () to move fluid from the inlet () to the outlet (). A motor () imparts rotation of the impeller () about the axis (). The motor () includes a motor stator () fixed to the stator assembly (), a motor rotor () fixed to the rotor assembly (), and a radial motor gap () between the stator () and the rotor (). The pump () is configured to direct a mixed blood flow from the fluid inlet () to the fluid outlet () and a wash flow through the motor gap ().
