Patent number: 11071819Abstract: Disclosed is a valve drive unit that has first and second SMA wires that can be alternatively activated. The valve drive unit further includes a pivoting member pivotably arranged around a pivoting member axis, the pivoting member including a valve driver arranged at a distance from the pivoting member axis. The first and second SMA wires are coupled to the pivoting member such that an activation of the first SMA wire causes the pivoting member to pivot into a first direction and an activation of the second SMA wire causes the pivoting member to pivot into a second direction, the second direction being opposite to the first direction. The valve driver is configured to releasably engage a valve driver coupler of a valve unit, such that, in the engaged state, a pivoting of the pivoting member is transmitted to the valve driver coupler via the valve driver.Type: GrantFiled: November 20, 2018Date of Patent: July 27, 2021Assignee: Roche Diabetes Care, Inc.Inventors: Hans List, Stefan Pfalz, Niklaus Schneeberger, Pierre Jaquier, Peter Siegrist

Patent number: 10512762Abstract: An implantable medical device is disclosed that includes a valve seat and a valve member movable with respect to the valve seat. An adjustment circuit assembly includes a resistive element that is coupled to the valve member and operable to position the valve member relative to the valve seat so as to alter the pressure setting in response to a current applied to the resistive element.Type: GrantFiled: March 8, 2016Date of Patent: December 24, 2019Assignee: Medtronic Xomed, Inc.Inventors: William Jeffrey Bertrand, Robert K. Vaccaro, Chun Man Alan Leung, Michael Ayoub, Pierre Jaquier, Laetitia Mayor, Thomas Junker, Guillaume Schmit

Patent number: 9423049Abstract: A reading and adjustment tool for use with a valve having a pressure or flow setting adjustable to a plurality of pressure or flow settings is disclosed. The tool includes a signal generator and an excitation coil coupled to the signal generator. The signal generator includes an adjustment interface configured to generate an adjustment signal to adjust the pressure or flow setting and a reading interface to generate a reading signal to read the pressure or flow setting of the valve. At least one excitation coil is connected to the signal generator and configured to generate an oscillating electromagnetic field based on one of the adjustment signal and reading signal. A sense coil can include two portions positioned on either side of the at least one excitation coil to determine the pressure or flow setting of the valve.Type: GrantFiled: August 25, 2014Date of Patent: August 23, 2016Assignee: Medtronic Xomed, Inc.Inventors: John R. Prisco, John Murdock Murphy, Jamie Hei, Laetitia Mayor, Pierre Jaquier
