Title: Forceps biopsique pour le prelevement de tissus et pour la coagulation le cas echeant
Inventor: COX DENNIS
IPC: A61B18/14
Filed: 1995-11-08
Granted: 2003-07-15
Abstract: Cette invention concerne des forceps biopsiques (10), notamment à usage endoscopique, qui permettent de couper et de retirer des échantillons de tissus et, le cas échéant de coaguler une incision tout en restant à l'endroit même de l'excision. Un fil de commande conducteur d'électricité (14) est connecté aux mâchoires (24, 25) et à la lancette (35) des forceps (10). Dans le cas où une coagulation est nécessaire, une décharge d'énergie électrique à haute fréquence est envoyée dans le fil de commande (14) et, par conséquent, dans les mâchoires (24, 25) et la lancette (35). Le patient (45) est également relié au circuit, généralement par une plaque de métal (44) appuyée contre sa peau. La chaleur dégagée permet de coaguler le tissu en contact avec les mâchoires (24, 25) et la lancette (35).

Abstract: A circuit for, and method of, reducing cross-coupled interference between first and second telephone lines of a multi-line telephone instrument and a telephone instrument containing the same. The circuit includes: (1) a first differential input amplifier having first tip and ring inputs coupled to conductors of the first telephone line and first tip and ring shunt resistors coupling the first tip and ring inputs to a signal reference of the telephone instrument and (2) a second differential input amplifier having second tip and ring inputs coupled to conductors of the second telephone line and second tip and ring shunt resistors coupling the second tip and ring inputs to the signal reference, the first and second tip and ring shunt resistors decreasing a common mode input resistance of the first and second differential input amplifiers, thereby attenuating cross-coupled interference common to both of the first and second telephone lines. The circuit and method may further be suitably employed to reduce the effects of common mode interference in other telephone instruments, including, but not limited to, single-line telephone instruments.

Abstract: A method and apparatus (4) for extraction of precious metals from their ores and the product (26) thereof. Oxidized ore comprising precious metals is exposed to a leaching solution (lixiviant) (254) comprising a relatively high concentration (activity) of dissolved hydrogen sulfide gas, a relatively high concentration (activity) of bisulfide ions, and a relatively low concentration (fugacity) of dissolved hydrogen gas. The hydrogen sulfide gas and bisulfide ions are preferably added to the solution by sulfate-reducing bacteria growing in a medium comprising dissolved sulfate ions and dissolved nitrate ions, but abiotic sources may also be used. Examples of such bacteria include mesophilic, fresh-water species such as Desulfobacterium catecholicum DSM 3882 and Desulfovibrio simplex DSM 4141; mesophilic, salt-water species such as Desulfovibrio salexigens DSM 2638; and thermophilic, fresh-water species such as Desulfomaculum kuznetsovii VKM B-1805.

Abstract: An implantation method is described which involves the successive introducti on of projecting multilateral needles into the spongy bone of a joint. The needles  are symmetrically spaced on the terminal surfaces of the endoprosthesis up to a resistance edge on one portion of an endoprosthesis and up to a resistance surface on a  second portion of the endoprosthesis. The remaining free area between the projectin g multilateral needles is filled up to the terminal surfaces in the "biological silence" by  osteoblasts. The endoprosthesis also includes a glenoid cavity and a head which have round terminal surfaces with the projecting multilateral needles placed thereon. The projecting multilateral needles have different lengths and mutually parallel axes which  are perpendicular to the planes in which the round resistance edge of the glenoi d cavity and  the resistance plane of the head are located.

Abstract: A single guide wire system for use in continually directional drilling of boreholes, includes a guidewire extending generally parallel to the desired path of the borehole (14). The guidewire (20) is connected at a first end (20) to one side of a reversible source of direct current (30), and at a second end (22) to ground (24). A second side of the DC sourc e is also connected to ground (32). A known current flow in a first direction for a first period of time and in a second direction fo r a second period of time produces corresponding static magnetic fields in the region of the borehole (14). The vector components of the fiel ds are measured in the borehole by a 3-axis magnetometer, and from these vector components the effects of the Earth's magnetic field are canceled and the distance and direction from the borehole to the guidewire are determined. These values permit control of further drilling of  the borehole along a desired path.

Abstract: A technique for phase-up of array antennas of regularly spaced lattice orientation, without the use of a near-field or farfield range.  The technique uses mutual coupling and/or reflections to provide a signal  from one element to its neighbors.  This signal provides a reference to allow for elements to be phased with respect to each other.  After the first stage of the process is completed, the array is phased-up into,  at most,  four interleaved lattices.  These interleaved lattices are then phased with respect to each other, thus completing the phase-up process.

Abstract: The amount of electrical power delivered to a dialysate heater in the dialysis machine is maximized without substantially exceeding a predetermined maximum allowed power comsumption for the dialysis machine. The instantaneous power consumed by the machine is measured (132) and compared to the maximum allowed power consumption (134, 136, and 138). The excess of power beyond the instantaneous power consumed up to the maximum allowed power consumption is then made available to the heater (142). The worst case power consumption limitations of the dialysis machine components do not adversely affect the heat available from the heater. The rate at which dialysis treatments may progress may increase or the time required for dialysis treatments may decrease.
