Publication number: 20240138899Abstract: Method and system of control of conductive fluid during coagulation using radio frequency energy. At least one example is of sealing blood vessels, the method comprising: applying, by an electrosurgical controller, radio frequency (RF) energy between two electrodes of a coagulation wand, the two electrodes abutting tissue at a surgical site, and the RF energy at a coagulation energy; supplying, by the electrosurgical controller, a flow of conductive fluid to the surgical site; measuring, by the electrosurgical controller, a value indicative of impedance of tissue and conductive fluid between the two electrodes; and decreasing, by the electrosurgical controller, the flow of conductive fluid as the value indicative of impedance decreases.Type: ApplicationFiled: September 21, 2023Publication date: May 2, 2024Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte.

Publication number: 20240108467Abstract: Delivery apparatus and methods for delivering a medical device into a patient's vasculature are disclosed. In some examples, a method includes inserting, into a patient, a distal end portion of a delivery apparatus including a radially compressed prosthetic valve mounted around a balloon, advancing the distal end through the patient's vasculature, and inflating the balloon to radially expand the prosthetic valve at a native heart valve. The delivery apparatus includes a handle, a first shaft and a second shaft extending from the handle, and a locking mechanism to prevent axial movement of the second shaft relative to first shaft. The second shaft extends coaxially through the first shaft and includes the balloon, the radially compressed prosthetic valve, and one or more radiopaque markers at a distal end portion. The first shaft includes an end piece covering a proximal portion of the balloon during the advancing of the delivery apparatus.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Philippe Marchand, David M.

Publication number: 20240109680Abstract: A cleaner assembly for an apparatus for making pouch products includes a cleaner roller and a poker roller. The cleaner roller may counter rotate with a rotatable drum of the apparatus, in contact with an upper surface of a first elastic layer on the rotatable drum, and at a greater tangential speed than at least one surface of an outer circumferential surface of the rotatable drum or an upper surface of the first elastic layer. The poker roller includes projections that are each configured to extend into one or more divots of the rotatable drum. The poker roller may counter rotate with the rotatable drum and at a same tangential speed as the at least one surface such that the projections extend into and out of separate, respective divots of the rotatable drum based on the counter rotation of the poker roller and the rotatable drum.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Applicant: Altria Client Services LLCInventors: Jarrod W.

Publication number: 20240099839Abstract: A delivery apparatus for a prosthetic heart valve includes a shaft, an inner balloon, and an outer balloon. The shaft has a lumen extending from a proximal end portion to a distal end portion and a plurality of openings formed in the distal end portion. The shaft is configured such that a fluid can flow through the lumen and the openings. The inner balloon has end portions and a center portion disposed between the end portions. The inner balloon is mounted on the distal end portion of the shaft and is in fluid communication with the openings of the shaft. When the inner balloon is inflated with the fluid, the end portions expand farther radially outwardly than the center portion. The outer balloon is mounted to the shaft and disposed over the inner balloon. The outer balloon is configured to fully expand after the inner balloon at least partially expands.Type: ApplicationFiled: December 11, 2023Publication date: March 28, 2024Inventors: Tri D. Tran, Ronaldo C. Cayabyab, David J. Evans, Sean Chow, Christopher Chia, Tamir S. Levi

Patent number: 8456644Abstract: Deformations of a surface of a test object can be measured by attaching mirrors to a surface of a test object, each mirror having a reflective surface with a dimension and a radius of curvature smaller than those of the surface of the test object. Light is directed towards the mirrors and a reference surface, and interference patterns are generated using light reflected from the mirrors and the reference surface. Changes in the surface of the test object are determined based on the interference patterns.Type: GrantFiled: September 2, 2010Date of Patent: June 4, 2013Assignee: Zygo CorporationInventors: Christopher J.

Patent number: 7410765Abstract: The present invention provides methods and materials that can be used to detect, examine and exploit protease mediated protein expression. An illustrative embodiment of the invention is a polynucleotide encoding a polypeptide having a plurality of operatively linked elements comprising a polypeptide degradation signal that functions as a proteosome substrate; a polypeptide of interest having an observable activity; and a linker disposed between the polypeptide degradation signal and the polypeptide of interest. The linker comprises a protease recognition motif that is capable of being specifically recognized and cleaved by a protease. The activity of the polypeptide of interest is observed when the motif is specifically recognized and cleaved by the protease; and the activity of the polypeptide of interest is decreased or not observed when the motif is not specifically recognized and cleaved by the protease.Type: GrantFiled: November 17, 2005Date of Patent: August 12, 2008Assignee: The Regents of the University of CaliforniaInventors: Arnaud Lacoste, Christopher J.
