Remote controls including a first button, a second button, transmission means, associated with the housing, for transmitting a signal to the ambulatory infusion device, and a controller associated with the housing and adapted to prevent signal transmission by the transmission means unless the second button has been actuated, to allow signal transmission by the transmission means in response to actuation of the second button, and to control the transmission means to transmit a signal in response to the first button being pressed concurrently with actuation of the second button or during a predetermined period after actuation of the second button.

Remote controls configured to prevent unintended signal transmission and ambulatory medical systems including the same

An implantable infusion system includes at least two controllable fluid transfer devices that may be used to transfer different fluid flows to the same or different body sites.

Implantable infusion device with multiple controllable fluid outlets

An implantable medication delivery device that is highly space efficient and can reliably and safely deliver controlled medication doses to a target site. The system includes a variable volume medication reservoir that is exposed to an ambient pressure equal to the ambient pressure at a system outlet port. A pump/valve subassembly is provided to draw medication from the reservoir and force a medication dose along a fluid transfer passageway to the outlet port. The pump/valve subassembly incorporates a safety mechanism, e.g., a balanced valve, which normally blocks medication flow to the outlet port and opens only in response to a pump induced unbalancing force. A protective shell is also disclosed for protecting the ambient reservoir.

Implantable medication delivery device

Remote controls, including a communication device, a button or other communication device actuator and a movable structure that allows actuation of the actuator in one position and prevents actuation of the actuator in another position to prevent inadvertent signal transmission.

Remote controls and ambulatory medical systems including the same

A method of preventing inadvertent signal transmission sent from a remote control for controlling the operation of an implantable infusion device. The method includes maintaining the remote control in a locked state prior to a user intentionally unlocking the remote control in order to generate transmission of a signal from the remote control to the implantable infusion device. The unlocking of the remote control can include moving a button control element, unlocking a button lock, pressing a button other than the signal generation button, pressing the signal generation button in a specific sequence or shaking the remote control.

This invention relates to methods, apparatuses and systems for testing the functionality of the pumping mechanism of a medical device, e.g., an implantable infusion pump, while the medical device is contained within a shipping package. The test apparatus enables such functional verification, without opening the shipping package, when the medical device is still contained within the package that has been appropriately sealed to maintain sterility of the medical device.

Test method and apparatus for verification of medical device functionality

An implantable medication delivery apparatus including a flow path coupling a medication reservoir to a device outlet port where the flow path includes a regulator means for limiting the magnitude of pressure transferred downstream from the medication reservoir. The regulator means is configured to respond to the reservoir pressure exceeding a certain threshold for closing a valve located downstream from the reservoir. The valve closure functions to isolate the device outlet port from further reservoir pressure increases which otherwise could induce unintended medication flow from the device outlet port.
