Pump includes a motor and a cam shaft coupled to the motor for rotation about a longitudinal axis of the cam shaft. The cam shaft has at least one radially-outward projection defining a helical engagement portion disposed along a length of the cam shaft. A plurality of finger plates are disposed along the length of the cam shaft, each finger plate mounted for movement in a transverse direction relative to the longitudinal axis of the cam shaft. Each finger plate has an aperture defined therein to receive the cam shaft therethrough. Each aperture has a substantially straight edge region and an opposing edge region. Engagement of the helical engagement portion with the substantially flat edge region during rotation of the cam shaft urges the finger plate transversely toward an extended position.

Pump, motor and assembly for beneficial agent delivery

A device for delivering a beneficial agent is provided and generally includes a cassette, a pump, and a delivery tube. The pump includes a pump housing containing a pump assembly having a fluid drive component. The pump housing has a receiving region disposed proximate the fluid drive component and further includes a rear closure portion. The rear closure portion includes a membrane disposed between the receiving region and the fluid drive component. The cassette includes a cassette housing, which has a cassette body region defining a fluid reservoir chamber therein. The cassette further includes a cassette base region having a boundary configured to be received by the receiving region.

Devices and methods for delivering a beneficial agent to a user

Device for delivering a beneficial agent includes a cassette including a cassette housing with a fluid reservoir and a cassette base region. The device also includes a delivery tube. The device also includes a pump including a pump housing containing a pump assembly having a fluid drive component. The pump housing has a receiving region to receive the cassette base region. The fluid drive component is proximate the receiving region. A lock member is coupled to the pump housing and movable between an open position and a closed position. The cassette is capable of being inserted into and removed from the receiving region when the lock member is in the open position, and the cassette is secured to the pump with the cassette base region within the receiving region and the delivery tube in operative engagement with the fluid drive component when the lock member is in the closed position.
