Publication number: 20240066214Abstract: A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Inventors: Dean Kamen, Larry Brian Gray, Eric Yeaton

Patent number: 11534543Abstract: A method for making a fluid delivery device including a reusable portion and a disposable portion. The disposable portion is adapted to be secured to a user and includes a conduit fluidly connecting a reservoir containing a fluid and a moveable pumping member. The moveable pumping member can expand an expandable structure with the fluid. The reusable portion is selectively engageable to the disposable portion and contains a drive device for engaging the moveable pumping member of the disposable portion. The drive device has a rotatable pumping actuation member with a plurality of projections for engaging the moveable pumping member and thereby moving the fluid to expand the expandable structure.Type: GrantFiled: July 1, 2019Date of Patent: December 27, 2022Assignee: DEKA Products Limited PartnershipInventors: Dean Kamen, Larry Brian Gray

Publication number: 20220265918Abstract: A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.Type: ApplicationFiled: April 29, 2022Publication date: August 25, 2022Inventors: Dean Kamen, Larry Brian Gray, Richard J. Lanigan, John Matthew Kerwin, Stephen Lewis Fichera

Patent number: 11293425Abstract: A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.Type: GrantFiled: June 24, 2019Date of Patent: April 5, 2022Assignee: DEKA PRODUCTS LIMITED PARTNERSHIPInventors: Dean Kamen, Larry Brian Gray, Russell H.
