Patent number: 11926877Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.Type: GrantFiled: June 17, 2021Date of Patent: March 12, 2024Assignee: The Board of Trustees of the University of IllinoisInventors: Diana Rose Ranoa, Robin L.

Patent number: 11925408Abstract: A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.Type: GrantFiled: December 13, 2022Date of Patent: March 12, 2024Assignee: Covidien LPInventors: Scott J.
