Patent number: 11369384Abstract: Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.Type: GrantFiled: May 27, 2020Date of Patent: June 28, 2022Assignee: COVIDIEN LPInventors: Rodney D. Raabe, Jack Chu, Don Crawford, Jan R. Lau, Zhenyu Zuo

Patent number: 8519287Abstract: A circuit breaker assembly includes a housing, a trip mechanism, a vent channel, and a chamber. The trip mechanism is positioned within the housing can causes a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault. The vent channel is formed in the housing and positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault to an aperture in the housing. The chamber has a chamber housing coupled to the housing adjacent the aperture such that the chamber receives the gas and debris exiting the aperture.Type: GrantFiled: November 15, 2010Date of Patent: August 27, 2013Assignee: Schneider Electric USA, Inc.Inventors: Rodney D.
