Publication number: 20240065759Abstract: An electrosurgical access catheter for assisting a physician perform an ancillary surgical procedure on a region of interest (ROI) in a patient has a tubular shaped elongate shaft and a ring-shaped active electrode located at the distal end. A passageway extends from the proximal section to the distal end of the shaft, and through the ring-shaped active electrode. The proximal section of the elongate shaft is detachably coupled to an electrosurgical controller such that the ring-shaped active electrode is operable with the electrosurgical controller and a dispersive electrode to electrosurgically make a circular-shaped incision through a tissue wall, carving a cylindrical-shaped tissue plug as the ring-shaped active electrode is advanced through the wall. The access sheath is advanced through the surgically created opening and without further dilation of the opening. The invention has particular applicability to the lung, and minimally invasive bronchoscopic procedures. Related methods are also described.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicant: Broncus Medical Inc.Inventors: Eric Gwerder, Thomas Keast, Henky Wibowo

Publication number: 20230381781Abstract: Methods, devices, and systems for performing isoelectric focusing reactions are described. The systems or devices disclosed herein may comprise fixtures that have a membrane. In some instances, the disclosed devices may be designed to perform isoelectric focusing or other separation reactions followed by further characterization of the separated analytes using mass spectrometry. Two or more isoelectric focusing reactions may be performed in parallel. The disclosed methods, devices, and systems provide for fast, accurate separation and characterization of protein analyte mixtures or other biological molecules by isoelectric point.Type: ApplicationFiled: May 16, 2023Publication date: November 30, 2023Inventors: Luc BOUSSE, Don Wesley ARNOLD, Wesley CHANG, Erik GENTALEN, Eric GWERDER, Scott MACK
