Assignee:

Medtronic MiniMed, Inc. - Northridge CA

International Classification:

A61K 9/22

US Classification:

6048901

Abstract:

A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.

Assignee:

Medtronic Minimed, Inc. - Northridge CA

International Classification:

A61M 1/00

US Classification:

604151

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. A method, system, and an article of manufacture for automatically detecting an occlusion in a medication infusion pump is provided. The electrical current to an infusion pump is measured. Based on measurements of one or more variables, the infusion pump detects whether there is an occlusion in the system. The methods of detecting occlusions may be dynamic.

Abstract:

An infusion media delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient and may be disposed of after it has been in use for a prescribed period. The disposable housing portion supports an infusion media reservoir and a needle on a moveable platform. The platform is moveable between a first position in which a needle is disengaged with a patient and a second position in which the needle is engaged with the patient.

Assignee:

Medtronic Minimed, Inc. - Northridge CA

International Classification:

A61M 5/178

US Classification:

60416401

Abstract:

An infusion medium delivery system, device and method for delivering an infusion medium to a patient-user, includes a needle inserter device and method for inserting a needle and/or cannula into a patient-user to convey the infusion medium to the patient-user. The needle inserter device and method operate to insert a needle and cannula into a patient-user's skin and automatically withdraw the needle from the patient-user, leaving the cannula in place and in fluid flow communication with a reservoir. The delivery device may include a base portion and a durable portion connectable to the base portion, and wherein the base portion can be separated from the durable portion and disposed of after one or more specified number of uses. The base portion supports the reservoir and the needle inserter device, while the durable portion supports a drive device for selectively driving the infusion medium out of the reservoir and into the needle and/or cannula.
