Patent number: 10744314Abstract: A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the medical valve has a housing with an inlet and an outlet, a rigid member movably mounted within the housing, and a resilient member with a sealing portion. The housing also has at least one relief zone that is in fluid communication with the outlet when the valve is in the closed mode. The rigid member may have a proximal end, a distal end, and a flow channel. The relief zone may be radially outward from the sealing portion. The sealing portion may seal the valve and prevent fluid from passing through the valve when in the closed mode.Type: GrantFiled: December 5, 2017Date of Patent: August 18, 2020Assignee: NP Medical Inc.Inventors: William Siopes, Luis Maseda, Ian Kimball

Patent number: 10716612Abstract: An electrosurgical device having a handpiece including a controller and an electrode assembly extending from the handpiece is disclosed. The electrode assembly includes a monopolar blade and a monopolar electrode. The monopolar blade includes a conductive element partially coated with an insulator and electrically coupled to the controller to selectively deliver a monopolar radiofrequency (RF) cutting signal. The monopolar electrode is spaced apart and electrically isolated from the monopolar blade. The monopolar electrode includes an exposed major conductive surface electrically coupled to the controller to selectively deliver a monopolar RF hemostatic sealing signal with a dispersed fluid.Type: GrantFiled: December 12, 2016Date of Patent: July 21, 2020Assignee: Medtronic Advanced Energy LLCInventors: Bhavesh Patel, Joseph Sylvester, David Hubelbank, Stephen Polgar, William Siopes, Rajan Patel
