Publication number: 20240096627Abstract: A method of forming a structure for etch masking that includes forming first dielectric spacers on sidewalls of a plurality of mandrel structures and forming non-mandrel structures in space between adjacent first dielectric spacers. Second dielectric spacers are formed on sidewalls of an etch mask having a window that exposes a connecting portion of a centralized first dielectric spacer. The connecting portion of the centralized first dielectric spacer is removed. The mandrel structures and non-mandrel structures are removed selectively to the first dielectric spacers to provide an etch mask. The connecting portion removed from the centralized first dielectric spacer provides an opening connecting a first trench corresponding to the mandrel structures and a second trench corresponding to the non-mandrel structures.Type: ApplicationFiled: April 27, 2023Publication date: March 21, 2024Inventors: Sean D. Burns, Lawrence A. Clevenger, Matthew E. Colburn, Nelson M. Felix, Sivananda K. Kanakasabapathy, Christopher J. Penny, Roger A. Quon, Nicole A. Saulnier

Publication number: 20220211942Abstract: A system for delivering an amount of fluid medium includes an injector, a delivery catheter and a pulsatile generator. The injector is configured for injecting the fluid medium during an injection cycle. The delivery catheter includes a conduit for delivering the fluid medium. The pulsatile generator is configured to apply a pulsatile force on the fluid medium delivered through the delivery catheter at a pulsation frequency. The pulsatile force is defined by a plurality of duty cycles during the injection cycle, each of the plurality of duty cycles including a first flow level and a second flow level that is lower than the first flow level. The pulsation frequency is 3 or more duty cycles per second.Type: ApplicationFiled: February 11, 2022Publication date: July 7, 2022Inventors: Matthew M. Burns, Tuan M. Doan, Rodney L. Houfburg, David M. Kaye, Todd J. Mortier

Publication number: 20220054751Abstract: A system for injecting medium into a patient includes an automated injector including a reservoir, an ejector for ejecting a volume of fluid medium from the reservoir, and an actuator coupled to the ejector. An input device includes a syringe housing, a plunger, a circuit board coupled to a first component of the input device, a plunger position sensor, a battery, and a transmitter for sending an input device action signal to the automated injector. The input device action signal is based at least in part on a signal sent from plunger position sensor. A diversion apparatus is disposed downstream from the reservoir and is configured to receive at least a first portion of the volume of the fluid medium ejected from the reservoir.Type: ApplicationFiled: September 10, 2021Publication date: February 24, 2022Inventors: Rodney L.

Patent number: 10835670Abstract: Systems and methods for modulating delivery of a fluid medium to a selected site within a patient's body are described. A system includes a syringe for injecting the fluid medium, a delivery catheter including a conduit for delivering the fluid medium from outside of the body to the selected site within the body, a diversion reservoir configured to receive a portion of the fluid medium, and a flow diverter assembly disposed in a fluid medium flow path between the syringe and the delivery catheter. The flow diverter assembly is configured to divert the portion of the fluid medium from the chamber of the syringe away from the delivery of the medium through the delivery catheter conduit during injecting with the syringe. The flow diverter assembly simultaneously increases fluid medium flow resistance with increasing pressure level of the fluid medium passing into the flow diverter assembly.Type: GrantFiled: February 28, 2018Date of Patent: November 17, 2020Assignee: Osprey Medical, Inc.Inventors: Matthew M. Burns, Tuan M. Doan, Rodney L. Houfburg, David M. Kaye, Todd J. Mortier
