Publication number: 20240148919Abstract: A navel cleaning device features a housing, a capsule containing a cleaning agent, and a dispensing mechanism that can be actuated to release the cleaning agent. The device may include a base circumscribing an aperture of the housing, and may include an applicator adjacent to or within the aperture. Upon placing the navel cleaning device on the abdomen of a user, actuation of the dispensing mechanism releases cleaning agent into the applicator for delivery to the navel. After the cleaning process, a clinician or user may then remove any liquid or residue from the navel. The navel cleaning device provides a means to cleanse the navel prior to surgical procedures performed therethrough, leading to a reduction in the overall time and expense of the operation.Type: ApplicationFiled: November 7, 2023Publication date: May 9, 2024Inventors: Reed Y. Nelson, Douglas Wirthlin, Kevin D. Seely

Patent number: 11947135Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between a light input surface and a light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, the alternating transmissive regions and absorptive regions have a transmission as measured with a spectrophotometer at a viewing angle of 0 degrees of at least 35, 40, 45, or 50% for a wavelength of the range 320-400 nm (UV) and/or at least 65, 70, 75, or 80% for a wavelength of the range 700-1400 nm (NIR). In another embodiment, the absorptive regions block light at the light input surface and light output surface and the maximum surface area that is blocked is less than 20% of the total alternating transmissive regions and absorptive regions. Also described are various optical communication systems comprising the light control films described herein and methods.Type: GrantFiled: December 12, 2018Date of Patent: April 2, 2024Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Daniel J.

Patent number: 11937815Abstract: A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob when an instrument shaft is engaged with the handle. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler and can provide certain motor drive profiles for predetermined positions of the stapler. The powered handle can include a manual return mechanism.Type: GrantFiled: June 3, 2021Date of Patent: March 26, 2024Assignee: Applied Medical Resources CorporationInventors: Erik D. Nelson, Jonathan R. Nash, Timothy M. Hopkins, Kevin Hudson, Andy Pham, Zachary W. Gyugyi, Joshua A. Spalding, Christian A Halvorsen

Patent number: 11197905Abstract: A composition includes a target pharmaceutical or biological agent, a solution containing the target pharmaceutical or biological agent, and substrate that is soluble in the solution. The substrate is capable of being solidified via a solidification process and the solidification process causes the substrate to become physically or chemically cross-linked, vitrified, or crystallized. As a result of the solidification process, particles are formed. The target pharmaceutical or biological agent within the solution retains proper conformation to ultimately produce a desired effect.Type: GrantFiled: July 24, 2019Date of Patent: December 14, 2021Assignee: TissueGen, Inc.Inventors: Jennifer Seifert, Paul R. Sood, Brent B. Crow, Kevin D. Nelson, Nickolas B. Griffin, Alpeshkumar P. Patel, Paul A. Hubbard
