Patent number: 10064993Abstract: 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: June 9, 2014Date of Patent: September 4, 2018Assignee: Bigfoot Biomedical, Inc.Inventors: Morten Mernoe, Mitchell Wenger, James Causey, Todd Kirschen

Patent number: 9717849Abstract: Some embodiments of an infusion pump system may include an occlusion sensor that can be used to detect when an occlusion exists in the fluid path between the medicine reservoir and the infusion site on the user's skin. Such an occlusion may occur, for example, when the fluid flow line (e.g., a cannula, infusion set tubing, or the like) is kinked. If the medicine dispensation path to the user is occluded, the user may receive no dosage or a lower dosage of the medicine. As such, the occlusion sensor can be used to indicate when the fluid is flowing or not flowing, thereby permitting the infusion pump system to communicate an alarm to the user if an occlusion exists.Type: GrantFiled: October 20, 2016Date of Patent: August 1, 2017Assignee: Bigfoot Biomedical, Inc.Inventors: Amit Mhatre, Jian Yao Wu, Mitchell Wenger, Steven A.
