Patent number: 9216053Abstract: An elongate member for inserting into a cannula is disclosed. The cannula comprises an electrically insulated region and an electrically exposed conductive region for delivering energy to form a lesion within a patient's body at an intended location relative to the electrically exposed conductive region. The elongate member is structured to cooperatively engage with the cannula at a pre-determined insertion depth and to provide a variation in radiopacity, at a pre-determined position relative to the electrically exposed conductive region, when inserted to the pre-determined insertion depth. The variation in radiopacity provides a visual reference for distinguishing, using fluoroscopic imaging, the intended location of the lesion.Type: GrantFiled: April 10, 2007Date of Patent: December 22, 2015Assignee: Avent, Inc.Inventors: Neil Godara, Krishan Shah, Amy Lefler, Robert Harrison

Patent number: 9119926Abstract: A subglottic suctioning system with a tracheal tube having a ventilation lumen, a cuff inflation lumen, and a suction lumen are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia. The suction lumen communicates with the space in the trachea above the cuff where secretions accumulate. The suction lumen has a valve on the proximal end for connection to a source of vacuum. The valve is adapted to interrupt the supply of vacuum to the suction lumen to allow for the introduction of a rinsing fluid in its place and to automatically re-establish the connection to the source of vacuum upon completion of rinsing. The rinsing fluid aids in maintaining an open suction lumen and may include medicaments and mucolytic agents to enhance or promote healing or to alter the properties of the mucus to make removal easier. The user may easily and repeatedly alternate suction and rinsing fluid through the suction lumen, i.e.Type: GrantFiled: July 31, 2009Date of Patent: September 1, 2015Assignee: AVENT, INC.Inventors: Brian J.
