Patent number: 9687603Abstract: Unexpected changes in the volume of therapeutic fluid in the reservoir of a fluid delivery device are detected based on changes in the pressure of the reservoir measured over a period of time by a pressure sensor. Additionally, an ambulatory reservoir fluid volume gauge is provided to indicate an actual volume of therapeutic fluid in a fluid delivery device reservoir. The actual volume of therapeutic fluid in the reservoir indicated by the ambulatory reservoir fluid volume gauge is determined based on changes in the pressure in the reservoir measured over a period of time by a pressure sensor.Type: GrantFiled: April 16, 2010Date of Patent: June 27, 2017Assignee: Medtronic, Inc.Inventors: Cynthia R. Nelson Konen, Irfan Z. Ali, Keith A. Miesel, Scott L. Kalpin

Patent number: 8668666Abstract: A method comprises measuring a volume of fluid delivered per pump stroke for each of a plurality of substantially identical medical pumps. The substantially identical medical pumps each have a fixed stroke length. The method further comprises: storing indications of the measured volumes on one or more data storage mediums; and for each of the plurality of substantially identical medical pumps, generating a separate therapy control program based on the indication of the measured volume associated with that one of the plurality of substantially identical medical pumps.Type: GrantFiled: March 19, 2012Date of Patent: March 11, 2014Assignee: Medtronic, Inc.Inventors: Nicholas R. Whitehead, John Michael Gray, James M. Haase, Cynthia R. Nelson Konen, Thomas W. Hovind, Dale A. Young

Patent number: 8632496Abstract: A medical pump subassembly comprises a magnetic cup forming a recess. The magnetic cup includes a protrusion within the recess. The cup forms a central aperture through the protrusion. The medical pump subassembly further comprises an electromagnetic coil within the recess and circumscribing the protrusion, a weld ring surrounding the recess, a barrier plate covering the recess, and a seal between the weld ring and the barrier plate to fluidically separate an interior of the cup from an external surface of the barrier plate.Type: GrantFiled: April 7, 2010Date of Patent: January 21, 2014Assignee: Medtronic, Inc.Inventors: Dale A. Young, Nicholas R. Whitehead, Ahmed Elmouelhi, John Michael Gray, James M. Haase, Thomas W. Hovind, Brian M. Pattock, Cynthia R. Nelson Konen
