Patent number: 8105279Abstract: Some embodiments of a medical infusion pump system include a pump device having a flexible pushrod that can adjust from a curved configuration to a generally straight configuration. The flexible pushrod is part of a drive system of the pump device so that the flexible pushrod can be controllably and incrementally advanced toward a medicine reservoir to incrementally dispense the medicine therein. In particular embodiments, the flexible pushrod may comprise an anti-rotation mechanism, an anti-torsion mechanism, or a combination thereof.Type: GrantFiled: September 18, 2006Date of Patent: January 31, 2012Assignee: M2 Group Holdings, Inc.Inventors: Morten Mernoe, Mitchell Wenger, James Causey, Todd Kirschen

Publication number: 20100228186Abstract: Some embodiments of a portable medical device, such as an infusion pump, can receive an external reference signal (e.g., a radio, cellular and/or satellite signal) to provide an automatic time-setting and maintenance operation. In these circumstances, the medical device can maintain accurate time and date information even in the event of a power interruption, a time-zone change and/or an internal clock error, for example. In this manner, the portable medical device provides safe operation and added convenience to the user.Type: ApplicationFiled: May 17, 2010Publication date: September 9, 2010Applicant: M2 Group Holdings, Inc.Inventors: Mark C. Estes, Mitchell Wenger

Patent number: 7625358Abstract: A flexible piston rod includes a piston and a row of elements, the top surface of one element being connected to the bottom surface of an adjacent element by a hinge that allows the two adjacent elements to pivot from a first position, where a portion of the top surface of one element abuts a corresponding portion of the bottom surface of the adjacent element and corresponding to a rectilinear, relatively stiff configuration of the piston rod, to a second position wherein the top surface of one element is spaced from the bottom surface of the adjacent element and corresponding to a curved configuration of the piston rod. Each element has cylindrical surface portions incorporating a thread for meshing with a corresponding thread of an actuator for displacing the piston rod longitudinally.Type: GrantFiled: April 5, 2007Date of Patent: December 1, 2009Assignee: M2 Group Holdings, Inc.Inventor: Morten Mernoe
