Title: Methods and systems for focused bipolar tissue ablation
Inventor: BEHL ROBERT S
IPC: A61B18/14
Filed: 2001-09-14
Granted: 2011-04-12
Abstract: Large tissue regions are treated using pairs of electrode arrays (12, 14). The electrode arrays may be concave and disposed in tissue so that their concave portions are opposed to each other. Axial conductors (16) may be provided extending from the arrays and toward each other in order to increase the heating of tissues lying along the axis between the deployed electrode arrays.  By properly spacing the electrode arrays apart and selecting the diameters of the arrays, desired volumes of tissue may be treated, typically with a bipolar, radiofrequency current.

Title: Method and apparatus for controlling the removal of heat from the condenser in a refrigeration system
Inventor: JUDGE JOHN F
IPC: F25B1/00
Filed: 2002-04-05
Granted: 2006-12-05
Abstract: This invention increases efficiency of a refrigeration system (10) by maximizing the cooling of the condenser (14) and reducing unnecessary work done by the compressor (12). In air cooled systems it will also increase the stability of the fans (16) by reducing fan cycling.

Patent CA-2460734-C (CA)
Inventor: GRAM ANKER
IPC: F17C5/02
Filed: 2002-09-13
Granted: 2010-06-29
Abstract: In the present method and apparatus, cryogenic liquid and vapor are pumped from a storage tank and the proportion of liquid and vapor is controlled so as to influence flow rate through the apparatus. In an induction stroke, the piston of a reciprocating pump is retracted and cryogenic fluid is drawn from the storage tank into a piston chamber associated with the piston. Flow rate is controlled through the apparatus by controlling the proportion of liquid and vapor supplied to the pump during the induction stroke by supplying substantially only vapor to the pump during a portion of the induction stroke.  In a compression stroke, the pump compresses and condenses vapor into liquid and then compresses any liquid within the piston chamber; compressed cryogenic fluid is ultimately discharged from the pump. The apparatus preferably includes a pump with a liquid supply line connecting a pump inlet to a storage tank, a vapor supply line connecting an ullage space with a pump inlet, an automatically actuated valve that opens and closes to control the flow of vapor to the pump inlet, and a controller that controls the valve to achieve a desired flow rate.

Title: An electrosurgical generator
Inventor: GOBLE COLIN CHARLES OWEN
IPC: A61B18/12
Filed: 2003-12-19
Granted: 2011-06-14
Abstract: An electrosurgical generator for supplying RF power to an electrosurgical instrument for cutting or vaporising tissue has an RF output stage (42) with an RF power bridge (Q1, Q2, Q3, Q4), a pair of output lines (74) and a series-resonant output network (48). The output impedance of the output stage (42) at the output lines (74) is less than 200/.sqroot.P ohms, where P is the maximum continuous RF output power of the generator. The generator offers improved cutting and vaporising performance, especially in relation to the reliability with which an arc can be struck when presented with an initial low impedance load. Overloading of the output stage is prevented by rapidly operating protection circuitry responsive to a predetermined electrical condition such as a substantial short-circuit across the output lines. In the preferred embodiment, the output stage is capable of maintaining output pulses at least 1kW peak by supplying the power bridge from a large reservoir capacitor (60).  Pulsing is dynamically variable in response to load conditions by controlling the maximum energy per pulse in response to the reservoir capacitor voltage.
