Patent number: 11464903Abstract: Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an exterior surface releasably attachable to a patient, a container disposed in an enclosed space defined by an interior surface of the main housing, and a drive assembly. The container may include a reservoir containing a drug and a stopper. The drive assembly may include drive housing and a tether which slidably engages and is pulled taut against a guide surface of the drive housing. A first end of the tether may be wound around a capstan which is mounted rotatably relative to the drive housing. A second end of the tether may be operably connected to a stopper biasing member. The tether may initially retain the stopper biasing member in an energized state.

Patent number: 11103636Abstract: An insertion mechanism for a wearable drug delivery device includes a needle hub, a needle coupled to the needle hub, a flexible boot removably coupled to the needle hub, and a cannula coupled to the flexible boot. The needle hub, the needle, the flexible boot, and the cannula are movable between a first position and a second position. Upon moving the needle hub, the needle, the flexible boot, and the cannula from the first position to the second position, the cannula engages a floor member to restrict movement of the cannula and the flexible movement towards the first position.Type: GrantFiled: June 22, 2018Date of Patent: August 31, 2021Assignee: AMGEN INC.Inventors: Jerome Olivas, Justin Harris, Sudeshna Dutta Ray, David Coleman, Eoghan McManus

Publication number: 20210228811Abstract: Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.Type: ApplicationFiled: September 17, 2019Publication date: July 29, 2021Inventors: Sudeshna Dutta Ray, Scott Robert Gibson, Daniel Eduardo Groszmann, Mehran Mojarrad, Andrew James Carlson, Lee Gordon Macklem, Mikhail Tikh

Publication number: 20210228797Abstract: Fluid path assemblies for drug delivery devices and methods of establishing a fluid flow path for drug delivery devices are described that include a needle shield valve member that couples to a reservoir having a needle mounted thereto. The needle shield valve member includes an internal barrier that protects the needle and/or contains a drug within the reservoir until activation of the drug delivery device. Upon activation, there is relative movement between the reservoir and needle shield valve member until the needle pierces the barrier to establish a fluid flow path from the reservoir through the needle shield valve member.Type: ApplicationFiled: July 12, 2019Publication date: July 29, 2021Inventors: Matthew Wayne Janke, Sudeshna Dutta Ray, Scott R. Gibson, Daniel Eduardo Groszmann, Wael Mismar, Mehran Mojarrad, Robert Allen Dees, Paul Daniel Faucher
