Patent number: 8444642Abstract: A laparoscopic nephrectomy device is disclosed. The device has an upper jaw and a lower jaw designed to clamp a portion of an organ, such as a kidney, so as to cut off blood flow locally to a portion of that organ. The upper jaw includes a mid-jaw piece and a top jaw piece, with each piece separately articulated. The mid-jaw piece is pivotably connected to the lower jaw. A top jaw piece is pivotably connected to the mid-jaw piece. The mid-jaw and top jaw pieces include a mechanism to fix the angular orientation of the mid-jaw and top jaw pieces with respect to one another, including a retractable slide piece that is carried by the mid-jaw piece and received in a slot in the top jaw piece. The jaws have insulated troughs that carry electrode structure for applying coagulative therapies.Type: GrantFiled: April 2, 2010Date of Patent: May 21, 2013Assignee: Device Evolutions, LLCInventors: Francisco Contijoch, Michelle Harran, Carolyn Purington, Tom Chen, Smita Mohan, Aubri Gillespie

Patent number: 7618370Abstract: A venous-arterial detector is disclosed. The detector includes a first chamber in fluid communication with a needle, and an indicator chamber in selective fluid communication with the first chamber through a valve. The indicator chamber is pre-pressurized to a defined pressure that preferably exceeds typical venous pressure, and the valve retains that pressure within the indicator chamber. When the needle is inserted into a vessel, if the pressure in the vessel is greater than the defined pressure in the indicator chamber, blood will flow into the indicator chamber, indicating that the vessel is most likely to be an artery.Type: GrantFiled: May 8, 2007Date of Patent: November 17, 2009Assignee: Device Evolutions LLCInventors: Jai Seung Choi, Kelvin Yu Chung Liang, Shente Steven Hsu, Eric Chi Kuo Lee

Publication number: 20080294036Abstract: A surgical metal detection apparatus. The apparatus comprises an elongate, tubular cannula and a removable element, which may be a trocar, releasably engaged within the cannula. A metal detection coil is positioned within the removable element or, in some embodiments, within the cannula. The metal detection coil is connected to a metal detection circuit which is adapted to detect the presence of a metallic element proximate to the end of the removable element or cannula. When a metallic element has been detected, the removable element may be removed from the cannula to permit the passage of a removal tool, such as a screwdriver, through the cannula without removing or changing the position of the cannula.Type: ApplicationFiled: April 22, 2008Publication date: November 27, 2008Applicant: DEVICE EVOLUTIONS, LLCInventors: Jennifer Hoi, Eli Luong, Laura Rupprecht, Christine Medina, David Huberdeau, Joe Chao, Michelle Harran, Soumyadipta Acharya
