Publication number: 20240108870Abstract: Presented herein are devices configured to deliver therapeutic substances to a fluidically-sealed chamber within the body of a recipient. The devices presented herein comprise a first/primary layer or substrate configured to be positioned adjacent a tissue barrier associated with the fluidically-sealed chamber. An adhesive is disposed on the primary layer to adhere the primary layer to the tissue barrier and provide a fluidic seal between the primary layer and the tissue barrier. In addition, a plurality of bioresorbable protrusions extend from the first layer and are configured to penetrate the tissue barrier and deliver a therapeutic substance to the fluidically-sealed chamber.Type: ApplicationFiled: March 18, 2022Publication date: April 4, 2024Inventors: Jonathon KIRK, Daniel SMYTH, Wolfram Frederik DUECK

Publication number: 20240058590Abstract: A catheter assembly may include a catheter adapter, a septum housing, and a septum. The catheter adapter may include a distal end, a proximal end, an inner wall extending between the distal end and the proximal end, and a lumen formed by the inner wall. The septum housing may include one or more protrusions and may be secured to the inner wall by one or more of the following: an interference fit between the one or more protrusions and the inner wall, a snap fit between the one or more protrusions and the inner wall, and bonding between the one or more protrusions and the inner wall. The septum may be at least partially disposed within the septum housing and configured to at least substantially seal the lumen.Type: ApplicationFiled: September 19, 2023Publication date: February 22, 2024Inventors: Jonathan Karl Burkholz, Daniel Kirk Hyer, Bin Wang, Tyler Warner, Ralph L.

Publication number: 20240023478Abstract: An improved bulk transfer system for an agricultural seeder or planter breaks up the central fill system into two stages for supplying a plurality of agricultural products simultaneously to an array of metering pods, each pod containing a plurality of metering assemblies. Firstly, there is a continuous transfer of agricultural product from a trailing product cart to intermediate mini tanks mounted on a central frame and located adjacent the seeding drills and plurality of metering assemblies. The pressurized mini tanks receive agricultural products on demand. Secondly, agricultural products are transferred on demand from the mini tanks to each of the corresponding metering assemblies along the seeding drill. This arrangement enables redistribution of the weight of the bulk of the product farther away from the seeding drills, allowing for greater tow-behind product volumes.Type: ApplicationFiled: September 16, 2021Publication date: January 25, 2024Inventors: Daniel Kirk Stanley MOLDER, Robert Sydney RUFF, Gordon Blair WILSON, Charles Joseph SCHEMBRI, Edward QUON, Colin Michael RUSH, Jason William SCHULTZ, Manmohanjit Singh JHEETEY

Patent number: 11413432Abstract: A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.Type: GrantFiled: October 1, 2019Date of Patent: August 16, 2022Assignee: Beeton, Dickinson and CompanyInventors: Daniel Kirk Hyer, Christopher Maul, Eric Davis, Bin Wang, Carl Ellis, Corey Christensen, Jonathan Karl Burkholz, Bart D.

Patent number: 10488183Abstract: A sensor system for sensing deformation of a flexible structure includes a beam structure that will be coupled to a surface of the flexible structure having a natural frequency fs, an axial strain ?axialstructure, and a shear strain ?xystructure associated therewith. The beam structure has an axial strain ?axialbeam and a shear strain ?xybeam associated therewith. The beam structure satisfies criteria defined by minimization of a root mean square difference between ?axialstructure and ?axialbeam and minimization of a root mean square difference between ?xystructure and ?xybeam. Fiber optic strain sensors are coupled to and distributed in a spaced-apart fashion along the beam structure. The beam structure is more flexible than the flexible structure such that a combination of the beam structure, the fiber optic sensors, and the flexible structure has a natural frequency fc defined by (0.95)fs?fc?(1.05)fs.Type: GrantFiled: December 22, 2017Date of Patent: November 26, 2019Assignee: United States of America as Represented by the Administrator of NASAInventors: Michael G.
