Filed:

Feb 10, 2004

Appl. No.:

10/774487

Inventors:

Patrick Paul - Downingtown PA, US
Sean O'Connor - West Chester PA, US

International Classification:

A61M037/00

US Classification:

604131000, 604126000

Abstract:

An external infusion device enclosed in a multiple-housing casing. Enclosed within an outer wall, a first housing encloses a reservoir of liquid and a drive mechanism. A second housing encloses a pump and electronics for controlling the drive mechanism to dispense the liquid from the reservoir according to a selected pattern. A separate third housing encloses a battery or batteries. The first and third housings are vented to atmosphere via primary vents with hydrophobic barriers. The second housing is vented to at least one of the first and third housings via a secondary vent with a hydrophobic barrier. The hydrophobic barriers allow passage of air, and allow pressure equalization, but prevent passage of liquid. Liquid entering one housing is prevented from flowing into the other adjoining housings.

International Classification:

A61M 5/142

US Classification:

604 67

Abstract:

Described is a medical infusion device that is configured to send and receive data on a real-time basis through the use of circuitry that enables the connection of the device to a cellular network. In one embodiment, a medical infusion device is provided that includes a housing having a drug reservoir, a first processing system and a drive mechanism adapted to receive and execute instructions from the first processing system. The drive mechanism is in mechanical cooperation with the drug reservoir for controlling expulsion of the drug from the reservoir. Medical infusion device also includes an input device for receiving external instructions and configured to transmit the external instructions to the first processing system, a display for receiving and displaying information from the first processing system, and a second processing system in communication with the first processing system for controlling communication between the first processing system and a remote processing system via a cellular network.

Appl. No.:

12/259481

Inventors:

Sean O'Connor - West Chester PA, US

Assignee:

Animas Corporation - West Chester PA

International Classification:

A61M 1/00

US Classification:

604131

Abstract:

Described is a drug delivery system and method for priming such drug delivery system so that unwanted delivery of a drug is prevented. In one embodiment, a drug delivery system is provided that includes a drug infusion pump and a cartridge configured for insertion into the drug infusion pump. The cartridge includes a hollow barrel for receiving and storing a drug and a plunger having a first end and a second end. The first end of the plunger is slidably insertable and movable within the barrel. The second end of the plunger is slidably insertable and movable with a chamber of the drug infusion pump. The second end of the plunger also includes an interlock that is passively engaged by a piston within the drug infusion pump during priming to prevent unwanted delivery of the drug.

Assignee:

Animas Corporation - West Chester PA

International Classification:

A61M 5/145

US Classification:

604151

Abstract:

The invention relates to a drug infusion device which may include a remote control unit and/or remote control unit capable of sampling and analyzing blood and interstitial bodily fluids. More particularly, the invention also describes a mechanism for delivering a fluid medication from a reservoir to a patient using a flexible reservoir and a stepped piston pump.

Appl. No.:

12/494546

Inventors:

Ian M. Shipway - Bryn Mawr PA, US
Sean O'Connor - West Chester PA, US

Assignee:

Animas Corporation - West Chester PA

International Classification:

A61M 31/00

US Classification:

604155

Abstract:

Described is a drive mechanism for a drug infusion pump. In one embodiment, an in-line drive mechanism is provided that includes a motor operatively coupled to a lead screw, which is configured to engage a piston. The piston includes a cavity to receive the motor and the lead screw such that the lead screw and at least a portion of the motor are substantially contained within the piston cavity when the piston is in a retracted position. In one embodiment, at least a portion of the motor is also substantially contained within a cavity of the lead screw regardless of whether the piston is in the retracted or extended position. The configuration of the piston, the lead screw and the motor results in a more compact drug delivery device.

Appl. No.:

12/569958

Inventors:

Sean O'Connor - West Chester PA, US

Assignee:

Animas Corporation - West Chester PA

International Classification:

A61M 5/142

US Classification:

604151

Abstract:

A medical device pump with a housing with a compartment for removably receiving a cartridge containing a therapeutic agent, a conduit configured to operatively provide a fluid flow path for therapeutic agent to exit from the cartridge, a user activated delivery button, a trigger mechanism, and a mechanical pump mechanism. The trigger mechanism, user activated delivery button and mechanical pump mechanism of the medical device pump are configured such that the trigger mechanism is activated by a user fully activating the user activated delivery button. Moreover, such full activation generates mechanical power employed by, and sufficient for, the mechanical pump mechanism to pump a predetermined volume of therapeutic agent from the cartridge and through the fluid flow path.

Inventors:

Sean M. O'Connor - West Chester PA, US

International Classification:

G01L 7/00

US Classification:

73714

Abstract:

Described is drug infusion device with one or more vents that permit the passage of gas between the exterior and interior of the device's housing. In one embodiment the device may include multiple interior chambers of differing volume and pressure sensors placed between them, while vents to ambient pressure are included in each chamber. According to this exemplary structure, the readings from the pressure sensor may be used to determine malfunctions in the venting of the device and/or changes in pressure that could cause the unintended delivery of medication.
