Publication number: 20140180276Abstract: A battery powered handheld air plasma spray was designed, developed and successfully demonstrated. The power supply includes a battery, a dc HID ballast and a series LC matching circuit. This matching circuit is designed to maintain the performance of the HID ballast while driving arc discharges, which are rotated around the electrodes by the magnetic field of a ring magnet. The produced plasma is in a non-equilibrium state; thus, the plasma effluent is low temperature (touchable) and yet carries abundant reactive atomic oxygen, which can rapidly activate blood coagulation processes and can effectively kill numerous microbes. This invention is for blood coagulation and sterilization applications. The device may be installed in vehicles and carried and operated in open fields without AC power sources. It may be used for bleeding control in a serious mishap to treat wounds without having to move the injured.Type: ApplicationFiled: October 15, 2013Publication date: June 26, 2014Inventor: Spencer P.

Publication number: 20140180286Abstract: A combination surgical device is provided and includes a dissection blade moveably mounted in a first jaw of the surgical device. The surgical device includes a second jaw movably mounted relative to the first jaw and a handle assembly. The handle assembly includes an advancement mechanism for incrementally advancing the blade out of the first jaw and a lever to open and close the first and second jaws. A lock member is provided to maintain the blade in an extended condition and a release lever is provided to disable the lock member. The surgical device additionally includes a safety or lock out mechanism which prevents the jaws from moving while the blade is in the extended condition.Type: ApplicationFiled: December 11, 2013Publication date: June 26, 2014Applicant: Covidien LPInventors: Stanislaw Marczyk, Christopher Switalski, Russell Pribanic

Publication number: 20140180281Abstract: An end effector assembly adapted to couple to an electrosurgical instrument, the end effector assembly including a plurality of spaced apart small seal plates on opposing jaw members where each seal plate forms a pair of seal plates with the corresponding seal plate on the opposing jaw member. Each pair of seal plates is individually activatable, and the pair of seal plates are activated in sequence. When the opposing jaw members are in an approximated position, the pairs of seal plates around the periphery of each jaw member define a gap therebetween that is larger than the gap between pairs of seal plates along the center of each jaw member.Type: ApplicationFiled: October 1, 2013Publication date: June 26, 2014Applicant: COVIDIEN LPInventor: CHRISTOPHER T. RUSIN

Patent number: 8753339Abstract: A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.Type: GrantFiled: February 21, 2013Date of Patent: June 17, 2014Assignee: Ulthera, Inc.Inventors: Robert L. Clark, III, James E. Chomas, Adnan I. Merchant, Ben F. Brian

Patent number: 8753341Abstract: An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally from the distal end of the housing. The elongated tube-like shaft includes a tube-like dielectric sheath and a tube-like electrode disposed coaxially through the tube-like dielectric sheath. The tube-like electrode is configured to operably couple to a source of electrosurgical energy and a proximal end of the tube-like electrode is adapted to operably couple to a source of suction. The tube-like shaft also includes a thermally conductive member. The thermally conductive member is disposed concentrically about the tube-like shaft and at least partially along a longitudinal length of the tube-like shaft. The thermally conductive member is configured to increase a surface area of the tube-like shaft to dissipate thermal energy about the increased surface area.Type: GrantFiled: June 19, 2009Date of Patent: June 17, 2014Assignee: Covidien LPInventors: Dana Landry, Mark J. Huseman, William Robinson

Patent number: 8753335Abstract: A device for delivering therapeutic energy to tissue is provided. The device includes a housing and a rotating device coupled to the housing. The device includes a plurality of electrodes, each electrode including: (i) a proximal section longitudinally extending from within the housing to an exterior of the housing and having a longitudinal axis; (ii) an intermediate section extending from the proximal section; and (iii) a distal section extending longitudinally from the intermediate section. The rotating device is coupled to the proximal sections of the plurality of electrodes and adapted to rotate the distal section of the electrodes so that distance between at least two electrodes changes, so that the electrodes can be placed in a compact configuration or an expanded configuration to provide for a treatment region larger than the size of the opening for insertion.Type: GrantFiled: January 25, 2010Date of Patent: June 17, 2014Assignee: AngioDynamics, Inc.Inventors: Meir H. Moshe, Valerie L. Douglass, Kevin L. Moss, Robert M. Pearson
