Patent number: 11904143Abstract: An injector includes a housing having a syringe assembly and an actuating mechanism at least partially disposed within the housing. The syringe assembly includes a syringe barrel that stores a medicament to be injected into a user, a needle assembly, and a filter member disposed adjacent to the needle assembly. The actuating mechanism is operatively coupled to the syringe assembly and includes a torque spring that exerts a torque to urge the medicament through the filter member to be injected into the user. The actuating mechanism further includes a damper mechanism that exerts an opposing force to dampen the motion exerted by the torque spring.Type: GrantFiled: June 4, 2018Date of Patent: February 20, 2024Assignee: AMGEN INC.Inventors: Adam B. McCullough, Ronald Forster, Joseph Michael Iglesias, Matias Melander, Rasmus Øhlenschlaeger, Christian Plambech, Lars Stenholt, Bjarke Lykke Ludvig Svendsen

Patent number: 11590294Abstract: A syringe assembly for a drug delivery device. The syringe assembly includes a syringe barrel having a proximal end, a distal end, and a longitudinal axis. A needle assembly is operatively coupled to the syringe barrel and includes a needle hub and a needle attached to the needle hub. A flexible connection is disposed between the syringe barrel and the needle hub and forms a fluid pathway between the syringe barrel and the needle. The flexible connection enables the needle assembly to be moveable from a filling position, in which a longitudinal axis of the needle assembly is parallel to a longitudinal axis of the syringe barrel, to an assembled position, in which the longitudinal axis of the needle assembly is not parallel to the longitudinal axis of the syringe barrel.Type: GrantFiled: June 1, 2018Date of Patent: February 28, 2023Assignee: AMGEN INC.Inventors: Adam B. McCullough, Hans Stenberg Knudsen, Rasmus Øhlenschlæger

Patent number: 11191904Abstract: A plunger configured as described herein provides geometry optimizations to minimize friction magnitude and variability during use by maintaining low deformation under large extrusion forces. More specifically, plunger embodiments described herein minimize a contact area between the plunger and a syringe or chamber, while also maintaining high contract pressures to maintain container closure integrity. Moreover, the plunger embodiments are configured to have minimal or no increase in the contact area under high loads associated with the delivery of viscous products.Type: GrantFiled: October 9, 2018Date of Patent: December 7, 2021Assignee: AMGEN INC.Inventors: Julian Jazayeri, Ronald Forster, Jolita Seckute, Olivia Alice Henderson, Kristen Brown, Gregory Gordon, Rasmus Øhlenschlæger, Peter Dan Kaare Soelberg

Publication number: 20210268192Abstract: A single-use auto-injector includes a housing and a dosing unit in at least part of the housing. The dosing unit includes a needle, a drug container with drug, a piston movable in the container, a first mechanical power supply for moving the piston to deliver the drug, an activation mechanism, and a mechanical escapement mechanism for controlling the movement of the piston. The auto-injector has a first state in which the needle is protected from needle damage or contamination, a second state in which the needle is ready to penetrate a human body, a third state in which the needle has penetrated the human body and is ready to dose, and a fourth state in which the needle is shielded to avoid unintended needle sticks. A second mechanical power supply is configured to shift state of the auto-injector from the third state to the fourth state.Type: ApplicationFiled: May 18, 2021Publication date: September 2, 2021Inventors: Hans Stenberg Knudsen, Christian Plambech, Rasmus Øhlenschlæger, Jørgen Jørgensen

Publication number: 20210093797Abstract: A drug delivery device may include a housing having an opening and a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening. A biasing member may initially be retained in an energized state, and may be released to drive a plunger to expel a drug from the drug storage container. The plunger may be configured to selectively rotate from an initial rotational position to a second rotational position under a biasing force exerted by the biasing member, and translate linearly in a distal direction to drive the stopper through the drug storage container after rotating from the initial rotational position to the second rotational position. A releaser member may have an initial position wherein the releaser member retains the biasing member in the energized state, and a second position wherein the releaser member generates an audible end-of-dose signal.Type: ApplicationFiled: September 29, 2020Publication date: April 1, 2021Inventors: Emil Finkelstein, Soren Forbech Skall, Lars Eilertsen, Rasmus Øhlenschlæger

Device and method for safe and easy removal of a needle shield element from a pharmaceutical syringe
Patent number: 10953161Abstract: A device for safe and easy removal of a rigid needle shield from a syringe, said device comprising a wall with an inner and an outer surface, the inner surface of the wall defining a tubular hollow portion along the longitudinal axis of the a rigid needle shield, said inner wall comprising a recess adapted to receive a compressible gasket movable within said recess along said longitudinal axis from a portion of the recess wherein said gasket is in a relatively uncompressed state to a portion of said recess wherein said gasket is in a relatively compressed state compared to the relatively uncompressed state, wherein said recess is arranged so that the gasket grips the rigid needle shield in the compressed state.Type: GrantFiled: August 8, 2018Date of Patent: March 23, 2021Assignee: Hoffmann-La Roche Inc.Inventors: Sylvain Lanzi, Maxime Gaillot, Rasmus Oehlenschlaeger -

Publication number: 20140243761Abstract: A regular metallic, cylindrical tubular needle cannula (1) is subjected to a metal etching liquid (5) in the inside lumen (11) thereby increasing the inside diameter and enhancing the flow properties while maintaining the outside appearance. The inside diameter is only increased over a controlled length (14) of the full length of the needle cannula (10) leaving sufficient length and wall thickness to also taper the outside diameter if so wanted.Type: ApplicationFiled: October 25, 2012Publication date: August 28, 2014Applicant: NOVO NORDISK A/SInventors: Dan N.
