Publication number: 20240024573Abstract: Apparatus and methods for introducing a solid or semi-solid intraocular drug-containing implant into the anterior chamber of an eye are described. The drug-containing implant can be a rod-shaped biodegradable implant that may provide for the extended release of the drug and may be effective for treating a medical condition of the eye. The apparatus is ergonomically designed in the shape or style of a pen with tactile surfaces for easy gripping, a needle-rotation knob to permit orientation of the needle bevel in relation to the eye, and a spring-actuated mechanism for consistent deployment of the implant.Type: ApplicationFiled: July 28, 2023Publication date: January 25, 2024Inventors: Zoran Novakovic, Rahul Bhagat, Shawn R. Davis, David Mucientes, Michael R. Robinson, Vaclav Vojan, Michael Strehl, Ina Michaelis, Maximilian Vogl, Jessica Kreher

Publication number: 20230090397Abstract: A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.Type: ApplicationFiled: November 29, 2022Publication date: March 23, 2023Inventors: Lorin Olson, Vaclav Vojan, Juergen E. Pfrang, Peter Krulevitch, Jingli Wang, Nicholas Foley, Mingqi Zhao, Paul Tashjian

Patent number: 9913951Abstract: A device for providing a medicament from capsules, where the device is integrated into an inhaler and comprises a capsule receiver comprising a capsule chamber, which extends along a first direction (X) in the manner of a tube and in which a capsule can be arranged, and a puncture device for opening the capsules, where the puncture device is arranged in a second direction (Y) radial to the capsule chamber, the puncture device having at least one needle which is moveable in sections into the capsule chamber in the second direction (Y) by means of an actuating button. A respective rear portion of the at least one needle of the puncture device is received in part in a needle receiver. The capsule receiver comprises at least one guide channel extending along the second direction (Y), wherein the needle receiver is arranged in the guide channel in such a moveable manner.Type: GrantFiled: June 20, 2016Date of Patent: March 13, 2018Assignee: Gerresheimer Regensburg GMBHInventors: Juergen Pfrang, Vaclav Vojan, Udo Leuschner
