Abstract: An inserter having a housing, a syringe carriage slidably mounted within the housing and a syringe socket defined within the syringe carriage. The syringe carriage is able to assume a cocked position and an extended position with the latter being the position for injection. A spring biases the syringe carriage to the extended position and a latch selectively retains the syringe carriage in the cocked position.

Abstract: A system for delivery of therapeutic and/or diagnostic agents into a living body includes a port assembly having a cannula extending from the mounting side, a port opening away from the mounting side and a resilient barrier between the port and the cannula. An access hub includes a connector positionable at the port for opening the resilient barrier. The access hub is movable in the port assembly, is engaged therewith through a resilient ring coupling and forms a seal with the resilient barrier, reducing the amount of volume to be primed. Inserters, both disposable and reusable, include the cannula insertion member as part of the assembly. A spring loaded port driver is operatively mounted within the housing with movement controlled by a latch. The driver includes a seat for receipt of a port assembly. The cannula insertion member is nonremovably fixed in a socket in the port driver in the disposable assembly.

Abstract: Apparatuses and methods for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump are provided. A base is provided which is adapted to receive a reservoir and engage a cap. A piercing member, such as a needle, is disposed in the interior of the cap in such a manner that the needle is separated from the reservoir septum when the base is in a first detent position, and the needle pierces a reservoir septum when the base is in a second detent position. When the reservoir, the base and the cap are connected to form an integrated unit, this unit is then capable of being inserted and secured in the infusion pump housing. In some embodiments, an integral connector couples directly to the reservoir.

Abstract: An improved pump, reservoir and reservoir piston are provided for controlled delivery of fluids. A motor is operably coupled to a drive member, such as a drive screw, which is adapted to advance a plunger slide in response to operation of the motor. The plunger slide is removably coupled to the piston. The piston comprises a first member and a second member. The first member has an external proximate side and an external distal side. The external proximate side is adapted to contact the fluid and is made of a material having a first stiffness. The second member has a first side and a second side and is at least partially disposed within the first member. The first side of the second member is adjacent to the external proximate side of the first member and is made of a material having a stiffness which is greater than the first stiffness.

Abstract: A hypodermic syringe employing a plunger slidably disposed within a barrel. The plunger has a mounting hole extending through the seal end thereof to receive a mandrel. The mandrel has a flexible flange to be releasably engaged with the plunger. A spring element withdraws the mandrel into a cavity within the plunger upon full extension of the plunger within the barrel. The barrel includes a hub retainer at the forward end thereof and a needle hub retained therein the mandrel includes barbed tines with surfaces having axes of the conical surfaces that are displaced from one another such that movement of the tines toward one another also brings the axes closer. A catch associated with the back end of the spring element coupled with the mandrel at the other end cooperates with shoulders on smooth surfaces within the cavities to retain tension within the bungee.

Abstract: Apparatuses and methods for dispensing flexible conduits, such as tubing or electrical cable, are disclosed, particularly for portable medical devices. An exemplary apparatus for dispensing flexible conduit or cable, includes a flexible conduit housing, including a base for temporarily housing a flexible conduit, the base having an opening for receiving the flexible conduit and a covet attached to the base for substantially closing the opening. The apparatus also includes an interface for mounting the housing. The flexible conduit is dispensable with the flexible conduit housing to a fixable variable length.
