Abstract: Valves, valved fluid transfer devices and ambulatory infusion devices including the same.

Abstract: A drug delivery device includes a blunt cannula and a reservoir. The blunt cannula has a cylindrical wall that defines an axial passage between a first end and a second end of the blunt cannula. The wall has at least a first tapered region at the first end to define an opening in fluid communication with the axial passage and adapted at the first end to resist interruption of fluid flow through the axial passage and out of the first end of the blunt cannula.

Abstract: An implantable medical device with a reservoir including a movable reservoir member, a fill port in fluid communication with the reservoir, and a valve that includes a housing including an opening in fluid communication with the fill port and the reservoir and a valve seat adjacent to the opening, and a valve element, operably connected to the movable reservoir member, that is movable relative to the valve seat between a closed position and an open. One of the valve seat and the valve element includes a main portion and a seal portion that is less tacky than the main portion and is in contact with the other of the valve seat and the valve element when the valve element is in the closed position.

Abstract: A fluid transfer device with a fluid transfer device housing, including a bore and a valve seat that extends around the bore, configured to be carried within the implantable medical device, a piston located within the bore, and a valve element movable relative to the valve seat. One of the valve seat and the valve element includes a main portion and a seal portion that is less tacky than the main portion and is in contact with the other of the valve seat and the valve element when the valve element is in the closed position.

Abstract: Implantable infusion devices and systems with side port access detection capability and methods of detecting side port access.

Abstract: Implantable infusion devices and systems with side port access detection capability and methods of detecting side port access. The methods may include the steps of sensing pressure in a fluid passage between an implanted pump mechanism and an implanted outlet port and determining that an implanted side port has been accessed by a hypodermic needle based on a predetermined change in pressure in the fluid passage between the implanted pump mechanism and the implanted outlet port.

Abstract: An ambulatory medical device including a reservoir, a fluid transfer device operably connected to the reservoir, and a pressure regulator that has a valve seat and a valve element movable between a closed position where the valve element engages the valve seat and prevents fluid flow and an open position where the valve element is in spaced relation to the valve seat and does not prevent fluid flow. One of the valve seat and the valve element includes a main portion and a seal portion that is less tacky than the main portion and is engaged by the other of the valve seat and the valve element when the valve element is in the closed position.

Abstract: An optically based transcutaneous blood gas sensor is provided having a reusable sensor head and a disposable sensing cap. A separate receptacle detachably connects to the sensor head and is attached to a person's skin by a layer of adhesive after a release liner is removed. The sensor head includes a sealed cavity housing one or more LEDs and one or more photodetectors. The disposable cap carries fluorescent targets which produces an amount of fluorescence as a function of blood gas concentration and the fluorescence is sensed by the photodetectors.
