摘要： A method for delivering RF energy to living tissue includes the steps of extending a guidewire to a tissue treatment site in a body. A controllable stiffness catheter is provided with a stiffness device and a temperature-changing device. The stiffness device is in a stiff state below a given temperature and in a soft state above the given temperature. While supplying power to the temperature-changing device, the catheter is threaded along the guidewire up to the treatment site in the flexible state of the catheter. Power is removed from the temperature-changing device to change stiffness of the stiffness device to the stiff state without straightening the catheter. The RF energy supply device is physically contacted with the treatment site and RF energy is delivered to the treatment site from the RF energy supply device.

摘要： A medical device includes a control handle having an articulation joint actuator, a surgical end effector, and a passive articulating joint connecting the end effector to the control handle. The articulation joint actuator, when unactuated, holds the passive articulation joint and, thereby, the end effector, in a substantially fixed articulation position, and, when actuated, releases the passive articulation joint into a freely articulating state to permit free articulation of the end effector with respect to the control handle dependent upon external forces acting upon the end effector. A method for operating the end effector includes retaining the passive articulation joint in a stable position with an articulation lock and actuating a release of the articulation lock to unlock the passive articulation joint and, thereby, permit articulating motion of the end effector through the passive articulation joint dependent upon the external forces acting upon the end effector.

摘要： A fluid conditioning system designed to be installed between the well perforation and the intake of a pump used to effect artificial lift is used to filter and chemically treat production fluids. The fluid conditioning system is an apparatus that provides scale inhibitors and/or other chemical treatments into the production stream. In some embodiments, the fluid conditioning system may be a part of the production stream filter wherein the filtering material is comprised of a porous medium that contains and supports the treatment chemical. In other embodiments, the chemical treatment may be accomplished by the gradual dissolution of a solid phase chemical. The treating chemical may be recharged or replenished by various downhole reservoirs or feeding means. In yet other embodiments, the treating chemical may be replenished from the surface by means of a capillary tube. In certain other embodiments, the apparatus may be retrievable from the surface thereby permitting recharge or replenishment of the chemical in the apparatus on an as-needed basis. The filtration apparatus may incorporate a by- pass valve that allows fluid to by-pass the filter as sand or other particulate matter fills up or blocks the filter.

摘要： Medical instruments are provided having end effectors (22 and 24) and end effector actuator apparatus (50) which are rotatable relative to the end effectors (22, 24). The instruments generally include a tube (20) which is typically coupled to the end effectors via a clevis (30) around which the end effectors pivot, a push rod (60) extending through the tube (20) and coupled to the end effectors (22, 24) an actuator apparatus (50) engaging the tube (20) and the push rod (60) and imparting reciprocal axial motion to the push rod (60) relative to the tube (20), and the end effectors (22, 24). The actuator apparatus (50) includes a sleeve (90), spring (103), handle (85), and lever arm (75). The sleeve (90) is movable along the longitudinal axis of the tube (20) against a biasing force of the spring (103) but is restrained from rotating about the tube (20). The sleeve (90) has a locking element on its proximal end. The handle (85) surrounds and rotatably engages the proximal end of the tube (20) and has a locking element on its distal end which mates with the locking element of the sleeve (90) and disengages therewith when the sleeve (90) is advanced along the tube (20). Upon disengagement, the tube (20), push rod (60) and end effectors (22, 24) can be rotated.

摘要： An electrocautery surgical device includes a battery power source and radio-frequency signal generating circuitry electrically coupled to the battery power source and operable to deliver power to an electrosurgical forceps. The radio-frequency signal generating circuitry includes a transformer having a primary winding and a secondary winding. The primary winding includes first and second primary sub- windings. At least one switching component is electrically coupled to the first and second primary sub- windings and is operable to switch between engaging the first primary sub-winding and engaging the second primary sub-winding such that a current flows through the first and/or second primary sub-windings. The first and second primary sub-windings have a different number of turns such that the radio-frequency signal generating circuitry produces a different impedance value depending on which one of the first and second primary sub- windings is engaged.
