Publication number: 20240100247Abstract: A drug delivery device includes a housing, a container disposed in the housing, an activation mechanism, a needle insertion mechanism, and a fluid flow path. The container has an inner volume to contain a medicament which is urged out of the container by the activation mechanism. The needle insertion mechanism includes an actuation assembly adapted to insert a needle and a cannula to deliver the medicament from the container and a valve assembly. The fluid flow connection is coupled with the container and the needle insertion mechanism and is adapted to allow the medicament to flow from the container to the needle insertion mechanism. The valve assembly is repeatedly movable between at least a valve open position and a valve closed position to selectively allow and restrict the medicament to flow through the needle and/or the cannula.Type: ApplicationFiled: October 1, 2020Publication date: March 28, 2024Inventors: Tohid Pirbodaghi, Joshua Tamsky, Paul Daniel Faucher, Jeff Lind, Scott R. Gibson, Sheldon B. Moberg, Samin Akbari

Patent number: 11938304Abstract: Impact testing apparatuses are disclosed which simulate and measure various impact-related events associated with the operation of a drug delivery device. The impact testing apparatus may include an impactor configured to simulate a plunger rod of the drug delivery device, and a guide sleeve configured to receive a syringe corresponding to the drug delivery device. The syringe may have a proximal end, a distal end defining an outlet, and an interior chamber extending between the proximal and distal ends and carrying a plunger. Additionally, the impact testing apparatus may include an energy source configured to reduce a distance between the impactor and the plunger so that the impactor strikes the plunger. Various sensors may be included to measure characteristics of one or more impacts caused by the impactor. Methods of impact testing a syringe filled with a fluid and carrying a plunger are also disclosed.Type: GrantFiled: November 30, 2022Date of Patent: March 26, 2024Assignee: AMGEN INC.Inventors: Julian Jazayeri, Sean Fitzgibbon, Joshua Tamsky, Christopher R.

Patent number: 11890450Abstract: A drug delivery device includes a housing defining a shell and an inner volume, a container, a drive mechanism, a needle assembly, a fluid flow connection, and a backflow prevention mechanism. The container has an inner volume to contain a medicament to be administered to a user. The drive mechanism is at least partially disposed within the housing and exerts a force to urge the medicament out the container. The fluid flow connection is coupled to the container and the needle assembly and allows the medicament to flow from the container to the needle assembly to be administered. The backflow prevention mechanism is associated with at least one of the container, the fluid flow connection, or the needle assembly and includes at least one flow restrictor to restrict a fluid from flowing from the needle assembly to the container.Type: GrantFiled: March 8, 2019Date of Patent: February 6, 2024Assignee: AMGEN INC.Inventors: Lawrence Scott Ring, Tohid Pirbodaghi, Samin Akbari, Daniel Eduardo Groszmann, Mehran Mojarrad, Mark Gordon, Mikhail Tikh, Jimmie L. Ward, Scott R. Gibson, Sheldon B. Moberg, Joshua Tamsky, Paul Faucher, Jeff Lind

Publication number: 20230347075Abstract: A drug delivery device includes a housing, a container disposed in the housing, a drive mechanism, a needle assembly, a fluid flow path, and a vortex flow adapter. The container contains a medicament which is urged out of the container by the drive mechanism. The needle assembly has a needle and/or a cannula to deliver the medicament from the container. The fluid flow path fluidically connects the container and the needle assembly. The vortex flow adapter is disposed within or defines at least a portion of the fluid flow path, and is adapted to urge the medicament to flow in a vortex pattern.Type: ApplicationFiled: November 17, 2020Publication date: November 2, 2023Inventors: Ali Nekouzadeh, Mehran Mojarrad, Joshua Tamsky, Paul Daniel Faucher, Scott R. Gibson, Kimberly Sepulveda, Sheldon B. Moberg

Publication number: 20220362462Abstract: A drug delivery device includes a housing, a container disposed in the housing, an activation mechanism, a needle insertion mechanism, a fluid flow connection, and a valve in fluid communication with the fluid flow connection and the needle insertion mechanism. The container has an inner volume to contain a medicament which is urged out of the container by the activation mechanism. The needle insertion mechanism is adapted to insert a needle and/or a cannula to deliver the medicament from the container via the fluid flow connection. The valve is in fluid communication with the fluid flow connection and needle insertion mechanism, and is movable between first and second positions. Upon insertion of the needle and/or the cannula, the valve remains in the first position whereby fluid flow is restricted. At a later time, the valve is urged to the second position whereby fluid may flow through the needle or cannula.Type: ApplicationFiled: September 9, 2020Publication date: November 17, 2022Inventors: Tohid Pirbodaghi, Paul Daniel Faucher, Joshua Tamsky, Scott Robert Gibson, Sheldon B.

Publication number: 20220355025Abstract: A drug delivery device includes a housing, a container disposed in the housing, an activation mechanism, and a needle insertion mechanism (NIM). The container has an inner volume to contain a medicament which is urged out of the container by the activation mechanism. The needle insertion mechanism (NIM) is operably coupled with the activation mechanism and includes an actuation assembly adapted to insert a needle and a cannula to deliver the medicament from the container. The actuation assembly is movable between a storage state, a first operational state, a second operational state, and a third operational state to selectively position the needle and the cannula.Type: ApplicationFiled: October 5, 2020Publication date: November 10, 2022Inventors: Tohid Pirbodaghi, Samin Akbari, Joshua Tamsky, Paul Daniel Faucher, Scott Robert Gibson, Sheldon B.
