Appl. No.:

11/646052

Inventors:

Julian D. Kavazov - Arcadia CA, US
Ian B. Hanson - Northridge CA, US

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.

International Classification:

A61K 9/22
A61M 5/178

US Classification:

6048901, 60416401

Abstract:

A delivery device includes first and second housing portions that selectively engage and disengage. A reservoir on one housing portion operatively engages a drive device and/or a needle inserting device on the other housing portion. Upon proper engagement of the housing portions, the reservoir operatively couples to the drive device and/or the needle inserting device. A first magnet on the first housing portion and a second magnet (or a magnetically-attractive material) on the second housing portion are positioned to magnetically interact with each other, upon operative engagement of the housing portions. A third magnet on the second housing portion may be opposed to the first magnet to help align the housing portions for connection. A magnet-responsive device may be on one or both housing portions to detect alignment and/or connection of the housing portions.

US Classification:

604123, 604122, 604124, 604125, 604222, 604151

Abstract:

Various embodiments of the present invention are directed to limiting a presence of air bubbles in a fluidic medium expelled from a reservoir. In various embodiments, a plunger head within a reservoir is shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir. Also, in various embodiments, a reservoir is shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir. In some embodiments, both a reservoir and a plunger head within the reservoir are shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir.

Assignee:

Medtronic MiniMed, Inc. - Northridge CA

International Classification:

A61M 1/00

US Classification:

604151, 604131

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-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.

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-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion medium are supported by the disposable housing portion, while the durable housing portion supports other components such as electronics and a drive device. A reservoir is supported by the disposable housing portion and has a moveable plunger that operatively couples to the drive device, when the disposable and durable housing portions are engaged.

Assignee:

Medtronic MiniMed, Inc. - Northridge CA

International Classification:

A61M 31/00

US Classification:

604 67

Abstract:

A delivery system for delivering fluidic media may include a second housing configured to be selectively operatively engaged with and disengaged from a first housing portion adapted to be carried by a user. One of the housing portions may support a reservoir for containing fluidic media and a plunger head moveable within the reservoir. A drive device may be supported by the other of the housing portions for coupling with the reservoir upon the housing portions being operatively engaged. A first interactive element may be supported on the first housing portion for interacting with a second interactive element supported on the second housing portion. Circuitry may be configured to detect an interaction between the interactive elements and configured to provide a signal or a change in state in response to the housing portions being operatively engaged and an interaction between the interactive elements being detected.

International Classification:

A61M 5/142

US Classification:

604151, 29428, 604533

Abstract:

A medical device system may include a set of housing portions, which includes a first housing portion and a second housing portion, and a third housing portion configured to be selectively operatively engaged with and disengaged from each of the first housing portion and the second housing portion. Each of one or more fluid conduits may provide a fluid path between a user and one or more reservoirs, for containing fluidic media, supported by at least one of the third housing portion and a selected one of the first housing portion and the second housing portion. A drive device supported by the third housing portion may be configured to transfer fluidic media between one of the one or more reservoirs and the user via the fluid conduit in a case where the third housing portion is operatively engaged with one of the first housing portion and the second housing portion.
