Patent number: 11806513Abstract: Plunger rod stops attach to existing syringes to limit the range of motion of the plunger, thereby to precisely control the amount of liquid that can be expelled from the syringe when the plunger rod stop is in place. In some embodiments, plunger rod stop devices generally include a body configured to attach to the plunger, and a stand-off extending from the body, configured to contact the finger flange when the plunger is depressed. In other embodiments, the plunger rod stop attaches to the finger flange or other fixed component of the syringe and the stand-off is configured to contact the plunger or plunger rod. Methods of the invention involve using the devices to interfere with the range of motion of the plunger, then reconfiguring or removing the device to allow the plunger to be moved a predetermined length, which corresponds to a precise dosage amount.Type: GrantFiled: May 13, 2021Date of Patent: November 7, 2023Assignee: TAKEDA PHARMACEUTICAL COMPANY LIMITEDInventors: Steve Bowman, Chase Fetzer, Richard Braga, Evi Shiakolas

Publication number: 20230304899Abstract: The present disclosure is directed to a device for screening pre-filled syringes configured to determine whether a stopper position within each syringe falls within an acceptable tolerance prior to final assembly of a syringe into a corresponding autoinjector device, thereby ensuring proper fit of the syringe within the autoinjector device and further ensuring accurate delivery of a desired dose of fluid from the syringe during operation of the autoinjector.Type: ApplicationFiled: March 24, 2023Publication date: September 28, 2023Inventors: Chase FETZER, Evi SHIAKOLAS

Publication number: 20230143477Abstract: A subcutaneous port assembly includes a base, a connector, a stem, a sealing element, and a locking member. The connector extends from a first end attached to the base to a distal end and includes an inner surface defining a socket having an inside diameter. The stem extends from the base and into the socket. The stem includes an outer surface having an outside diameter that is less than the inside diameter of the socket. The sealing element is disposed within the socket between the stem and the inner surface of the socket. The locking member has a plunger received within the socket from the distal end and having a terminal end facing the sealing element. The plunger is axially movable between a first position and a second position to selectively compress the sealing element within the socket.Type: ApplicationFiled: April 2, 2021Publication date: May 11, 2023Applicant: Takeda Pharmaceutical Company LimitedInventors: Ayesha Arzumand, Chris Tarapata, Marc Bellisario, Christel Hartshorn, Matthew J.
