Patent number: 10772796Abstract: Various embodiments of the present invention are directed to transferring fluidic media from a vial to a reservoir. In various embodiments, fluidic media may be transferred from the vial to the reservoir by moving a housing portion to move a plunger head located in the reservoir to draw fluidic media from the vial to the reservoir. In other embodiments, fluidic media may be transferred from the vial to the reservoir while the reservoir is held by a holding unit and vibrated by a vibrator to remove air from the fluidic media. In some embodiments, fluidic media may be transferred from the vial to the reservoir by moving a handle operatively connected to a bias member for assisting with the transfer of fluidic media. In other embodiments, the transfer of fluidic media may be assisted by a bias member and a needle connecting atmosphere and the vial.Type: GrantFiled: April 30, 2018Date of Patent: September 15, 2020Assignee: Medtronic MiniMed, Inc.Inventor: Julian D.

Patent number: 8840586Abstract: 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.Type: GrantFiled: October 27, 2006Date of Patent: September 23, 2014Assignee: Medtronic MiniMed, Inc.Inventors: Paul F.
