International Classification:

A61M 100

US Classification:

604153, 4174777

Abstract:

An implantable drug infusion device includes a pump tube for holding a liquid to be pumped. A race is configured to support the tube.

International Classification:

A61K 922

US Classification:

6048911, 604 66, 604132

Abstract:

An bolus delivery system includes an implantable pump, a sensor for sensing an adverse patient condition, such as atrial fibrillation, and a catheter for delivery of a bolus of drug to a target area of a living body. The pump is provided with a bolus metering assembly which includes, in a preferred embodiment, an auxiliary bellows defining a bolus reservoir in addition to the main reservoir of the pump. The auxiliary bellows is selectively placed in fluid communication with the pressurized main supply of drug via an inlet valve to refill the bolus reservoir. An outlet valve is provided to permit egress of the bolus to the catheter from the bolus reservoir. A drive train including a stepper motor and a face cam selectively opens and closes the inlet and outlet valves to effect accumulation or metering and delivery of the bolus. The auxiliary bellows is preferably provided as a collapsible element resiliently biased to an expanded position and is collapsed under pressure in the main reservoir to expel the bolus.

US Classification:

604151, 604153, 4174773, 4174777

Abstract:

An implantable drug infusion device includes a pump tube for holding a liquid to be pumped. A race is configured to support the tube. A roller assembly is configured to compress the tube against the race at one or more points along the path, and the roller assembly includes at least one roller. A drive assembly drives the roller assembly relative to the tube along the path so as to move the liquid through the tube. A biasing member is operably connected to the at least one roller to bias the at least one roller against the tube.

US Classification:

604151, 4174777

Abstract:

An implantable drug infusion device includes a pump tube for holding a liquid to be pumped. A race is configured to support the pump tube. A roller assembly is configured to compress the tube against the race at one or more points along the path, and the roller assembly includes at least one roller and a hub. A drive assembly drives the roller assembly relative to the tube along the path so as to move the liquid through the tube. A retracting roller is operably connected to the hub and/or one or more adjacent rollers to permit retraction of the roller during installation of the pump tube between the roller and the race.

Abstract:

In general, the disclosure is directed toward releasing material within a medical device via an optical feedthrough. A system for releasing material with a medical device comprises a cup that holds a material, wherein the cup includes a discharge port, a seal disc that seals the material within the cup, an optical feedthrough assembly coupled to the cup, a shell that defines a chamber within a medical device, wherein the optical feedthrough assembly is coupled to the shell, and a radiant energy source that shines a beam through the optical feedthrough assembly to puncture the seal disc to allow the material to enter the chamber via the discharge port.
