  • Patent number: 6958062
    Abstract: A multiple antenna ablation apparatus includes an electromagnetic energy source, a trocar including a distal end, and a hollow lumen extending along a longitudinal axis of the trocar, and a multiple antenna ablation device with three or more antennas. The antennas are initially positioned in the trocar lumen as the trocar is introduced through tissue. At a selected tissue site the antennas are deployable from the trocar lumen in a lateral direction relative to the longitudinal axis. Each of the deployed antennas has an electromagnetic energy delivery surface of sufficient size to, (i) create a volumetric ablation between the deployed antennas, and (ii) the volumetric ablation is achieved without impeding out any of the deployed antennas when 5 to 200 watts of electromagnetic energy is delivered from the electromagnetic energy source to the multiple antenna ablation device. At least one cable couples the multiple antenna ablation device to the electromagnetic energy source.

  • Publication number: 20050124885
    Abstract: A method and associated apparatus are disclosed for determining the location of an effective center of fluid flow in a vessel using an ultrasound apparatus. Ultrasound energy is propagated along an axis of propagation and projects upon the vessel. A Doppler-shifted signal reflected from the fluid in the vessel is received and a set of quantities expressed as a density is derived from the Doppler shifted signal for each of a set of coordinates, the density being a function of the Doppler shift in frequency associated with each of the coordinates. One of a mean, mode or median is calculated for each of the dimensions of the set of coordinates in conjunction with the density associated therewith. This calculation is repeated throughout the field of view of the vessel to define a centerline.

  • Publication number: 20050016979
    Abstract: A cooling system connected to provide coolant to a welding-type component automatically circulates coolant through the welding component upon activation of the welding component. A controller is configured to regulate the cooling system such that upon activation of the welding-type component coolant is caused to at least flow through the welding-type component and circulate after deactivation of the welding torch until a temperature of the coolant falls below a certain value or a specified time period has expired.

  • Publication number: 20040249239
    Abstract: An apparatus comprising an elongate probe member having proximal and distal extremities for use with a suction source to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity. The elongate probe member has a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body. The distal extremity of the elongate probe member has an outer surface and is provided with at least one recess opening onto the outer surface and an internal passageway communicating with the recess. When the suction source is coupled to the apparatus a suction is created in the recess by means of the passageway to draw the portion of the wall into the recess. A hollow needle is slidably disposed in the elongate probe member and has a distal end portion.

  • Publication number: 20040158136
    Abstract: An injection device for use with tissue of a mammalian body comprising a first tubular member and a second tubular member slidably disposed in the first tubular member. The first and second tubular members have respective proximal and distal extremities. The distal extremity of the second tubular member is provided with a needle that is extendable from the distal extremity of the first tubular member. The proximal extremity of the second tubular member is lockable relative to the proximal extremity of the first tubular member. The second tubular member has a column strength when locked within the first tubular member for limiting retraction of the second tubular member relative to the first tubular member during puncture of the tissue by the needle.

  • Publication number: 20030199730
    Abstract: A method for forming a valve-like mechanism in a body of a mammal having an esophagus extending through a lower esophageal sphincter to a stomach and formed by a wall having a muscle layer and a mucosal layer. The method comprises the step of forming at least one implant in the muscle layer of the wall in the vicinity of the lower esophageal sphincter. The at least one implant inhibits opening of esophagus at the lower esophageal sphincter and causes the mucosal layer to appose in the vicinity of the implants.
