Publication number: 20120059320Abstract: An infusion set is provided for use in delivering fluid through a cannula, which is housed on a cannula housing, to a selected subcutaneous infusion site on a patient. The fluid is generally a medication, e.g., insulin. The cannula is in fluid communication with a fluid passageway surrounded by a projection on the cannula housing that includes one or more rail-like extensions acting as guides. A connector connects the cannula housing to a fluid delivery system, e.g., an infusion pump. The connector includes a needle, one or more guide arms that slide over the rail-like extensions to guide the needle into the self-sealing septum, and one or more locking arms, with barbs at the end, to connect with corresponding recesses in the cannula housing. An introducer having one or more similar guide arms and locking arms, and a longer needle, may be used to insert the cannula into the patient.Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: SUSIE E.

Publication number: 20110230834Abstract: Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.Type: ApplicationFiled: May 27, 2011Publication date: September 22, 2011Inventors: Julian D. Kavazov, Rafael Bikovsky, Arsen Ibranyan, David Hezzell, Christopher G. Griffin, Mike Lee, Truong Gia Luan, Benjamin X. Shen, Thomas Miller

Patent number: 7905868Abstract: 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.Type: GrantFiled: October 27, 2006Date of Patent: March 15, 2011Assignee: Medtronic Minimed, Inc.Inventors: Sheldon B. Moberg, R. Paul Mounce, Paul F. Bente, IV, Ian B. Hanson, Julian D. Kavazov, Christopher G. Griffin, Colin A. Chong, Philip J. Hudak

Publication number: 20100331824Abstract: 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.Type: ApplicationFiled: September 3, 2010Publication date: December 30, 2010Inventors: Sheldon B. Moberg, Paul F. Bente, IV, Bradley J. Enegren, Christopher G. Griffin, Ian B. Hanson, Julian D. Kavazov, R. Paul Mounce, Stutz H. William

Patent number: 7744589Abstract: 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.Type: GrantFiled: June 7, 2007Date of Patent: June 29, 2010Assignee: Medtronic Minimed, Inc.Inventors: R.
