| 20090036870 | INFUSION MEDIUM DELIVERY DEVICE AND METHOD WITH DRIVE DEVICE FOR DRIVING PLUNGER IN RESERVOIR - 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. | 02-05-2009 |
| 20090171291 | SYSTEMS AND METHODS ALLOWING FOR RESERVOIR FILLING AND INFUSION MEDIUM DELIVERY - A system includes a durable portion with a durable housing and a separable disposable portion with a disposable housing that selectively engage with and disengage from each other. The disposable housing secures to a 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 an infusion medium may be part of the disposable portion to allow for disposal after a prescribed use. A reservoir for holding the infusion medium may be part of the disposable portion, and may be supported by the disposable housing. The durable portion may include other components such as electronics for controlling delivery of the infusion medium from the reservoir, and a drive device including a motor and drive linkage. | 07-02-2009 |

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. | 10-29-2009 |
| 20100331824 | INFUSION MEDIUM DELIVERY SYSTEM, DEVICE AND METHOD WITH NEEDLE INSERTER AND NEEDLE INSERTER DEVICE AND METHOD - 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. | 12-30-2010 |
| 20110160650 | RETENTION SYSTEMS AND METHODS - A system for retaining a fluid delivery device, the fluid delivery device may include a reservoir and a plunger arm operatively connected to a plunger head arranged for movement within the reservoir, the plunger arm having an arm portion operatively engageable with a drive member configured to move the plunger arm and the plunger head when the plunger arm and the plunger head are connected to the drive member. The system may include a rigid member arranged for movement and a bias member configured to urge the rigid member toward the plunger arm to force the plunger arm against the drive member to operatively engage the plunger arm to the drive member. | 06-30-2011 |
