Patent number: 11964129Abstract: In various embodiments, a drug pump includes a housing and, within the housing, an expandable drug reservoir at least part of which is exposed to a pressurized propellant. The propellant exerts a substantially constant pressure on the drug reservoir. A flow restrictor significantly limits outflow from the pump, and preferably has both a small diameter and a long path length, which acts to control the outflow from the drug reservoir. As a result, the pump produces a substantially constant outflow.Type: GrantFiled: March 1, 2019Date of Patent: April 23, 2024Assignee: MiniPumps LLCInventors: Jason Shih, Gregory Harbers, Richard Purvis, Miho Matsuoka, Andrew Urazaki, Mark Humayun, William Andrew Brandt, Atoosa Lotfi, Didier Sagan, Andrew Dunn

Patent number: 11925790Abstract: Processes and devices provide parenteral delivery of therapeutic fluids, in particular high-viscosity therapeutic fluids (e.g., protein therapeutics), by a chemical reaction that generates a gas. A device may include a first actuation chamber containing a first reagent, a second reaction chamber containing a second reagent, and a third therapeutic fluid chamber containing the therapeutic fluid. In a loaded configuration, a plunger separates the first chamber from the second chamber.
