In operation, a controller may be configured to control a speed of the blood pump based on a value from the first sensor and a value from the second sensor.

Abstract: A plug for a blood pump may be provided. The plug may include a housing. A central optical ferrule, coaxial with a central axis of the housing, may extend partially through the housing. A first end of the central optical ferrule may be an axial distance from an outer surface at a first end of the housing. The plug may include a plurality of electrical pins, each pin disposed parallel to the central axis and independently at a radial distance from the central axis. Each electrical pin may have an end extending through the housing and extending beyond the first end of the central optical ferrule.

Each additional ferrule being parallel to the central axis and disposed at a radial distance from the central axis.

Abstract: A blood pump with a stator and rotor wherein the rotor is assembled by bonding the stator components with epoxy. The bonding surfaces of the rotor components are primed with a silane-based primer to improve adhesion between the primer and the rotor components by rendering such surfaces hydrophobic. A bonding surface of one of the stator yoke or the stator sleeve, or both, is treated with a primer that improves wettability of the bonding surface and improves bonding of the epoxy to the binding surface. The device has a bonding surface adhered to epoxy in which a primer was applied on such bonding surface prior to introducing epoxy onto the bonding surface. In addition to improved bond strength, hydrophobic surface would control moister ingress.

Abstract: A graft system may be provided. The graft system may include a graft, a hemostasis valve operably coupled to a proximal end of the graft, and a clamp disposed around the proximal end of the graft and configured to hold the hemostasis valve in place relative to the graft. The graft may include a woven or knitted fabric. The clamp may be removably, or permanently, attached to the graft. The hemostasis valve may include a slit membrane disposed within a housing. The hemostasis valve may include an introducer sheath coupled to the housing. The housing may include two portions coupled together along two axial seams, each axial seam extending from a proximal end to a distal end of the hemostasis valve. A grommet may be coupled to an end of the graft.

Abstract: Systems and methods for providing hemodynamic support to a patient with an intravascular blood pump are disclosed. In some implementations, the blood pump includes a motor and an improved motor cable for delivering electrical power to the motor. The motor includes a stator with one or more coils. The motor cable includes one or more electrical conduits. The motor cable also includes a tail portion and a head portion. In some implementations, the head portion may have an O-shape or a C-shape. The motor cable may reduce the complexity of assembling the blood pump. For example, the motor cable may reduce the risk of shorting the one or more coils and/or the one or more electrical conduits.

Abstract: The Navigator is multiple degree of freedom neuro rehabilitation system. The Navigator simultaneously exercises both pronation and supination of the wrist (rotation) and flexion and extension of the fingers (grasp and release) for rehabilitation and monitoring of patients with motor control deficits due to a neurological ailment, such as stroke. In addition, the Navigator provides a visual, interactive environment for performing therapeutic exercises. The interactive environment provides motivation to the patient and can provide real-time feedback to the patient about the quality of the movements being performed.
