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.

Publication number: 20100152674Abstract: Needle inserting devices, as well as fluid flow connections and infusion medium delivery systems and methods that may be used with needle inserting devices are described, for medical or non-medical systems, such as, but not limited to sensors, monitors, or the like. The needle inserting device and method may operate to insert a needle or cannula through a patient-user's skin, for example, to provide a fluid flow path for conveying an infusion medium through a hollow channel in the needle or cannula and into the patient-user and/or to convey a fluid from the patient-user to one or more sensor elements. Embodiments of the present invention may be configured, as described herein, to provide a reliable, cost effective and easy-to-use mechanism for inserting a needle or cannula to a specific depth into a patient-user with minimal traumatic effect. In some embodiments, a mechanical force in a first direction results in a needle insertion at a non-zero angle relative to the first direction.Type: ApplicationFiled: August 23, 2007Publication date: June 17, 2010Inventors: Julian D.
