摘要： An implantable valve for controlling the passage of cerebrospinal fluid (CSF) from a ventricle of the brain to a suitable drainage location in the body includes a movable diaphragm responsive to pressure differentials between the ventricle and the drainage location. When the pressure differential is below a minimum threshold level, the valve is closed and CSF flow is prevented. When the pressure differential increases beyond the minimum threshold, the valve operates in a constant pressure mode to maintain a first predetermined CSF pressure differential across the valve. When the differential pressure increases beyond an intermediate threshold level, the valve operates in a flow control mode to maintain a desired CSF flow rate through the valve. When the pressure differential increases beyond a maximum threshold level, the valve operates in a constant pressure mode to maintain a second predetermined CSF pressure differential across the valve. To provide for the various valve operating modes, the valve includes a valve stem and a valve closure member, which coact with a valve seat carried on the diaphragm. The valve closure member defines an annular valving surface which coacts with the diaphragm to provide improved fluid control at low differential pressures.
摘要翻译：用于控制脑脊液（CSF）从脑室流通到体内适当引流位置的可植入阀包括响应于心室和排液位置之间的压力差的可移动隔膜。当压差低于最小阈值水平时，关闭阀门，并防止CSF流量。当压力差增加超过最小阈值时，阀以恒定压力模式运行，以保持横跨该阀的第一预定的CSF压力差。当差压增加超过中间阈值水平时，阀以流量控制模式运行，以保持通过阀的期望的CSF流速。当压差增加超过最大阈值水平时，阀以恒定压力模式运行，以保持横跨阀的第二预定的CSF压力差。为了提供各种阀门操作模式，阀包括阀杆和阀关闭构件，其与承载在隔膜上的阀座共同作用。阀关闭构件限定了与隔膜共同作用的环形阀门表面，以在低压差下提供改进的流体控制。

摘要： A tubing assembly is provided which includes a length of elastomeric tubing over which is positioned and affixed a substantially shorter length of tubing having micro orifices ion sputtered therethrough. The tubing assembly is manufactured by a method that includes stretching the elastomeric tubing in association with the application of medical adhesive at an interface between the elastomeric tubing and the ion sputtered tubing, and relaxing the elastomeric tubing to provide an effective seal along the ends of the ion sputtered tubing. These tubing assemblies are particularly suitable for use as ventricular catheters within intracranial pressure relief systems.

摘要： A method and apparatus for transmural ablation using an instrument containing two electrodes or cryogenic probes. A clamping force is exerted on the two electrodes or probes such that the tissue of the hollow organ is clamped therebetween. Bipolar RF energy is then applied between the two electrodes, or the probes are cryogenically cooled, thus ablating the tissue therebetween. The method provides for ablating cardiac tissue of a patient utilizing a sub-xyphoid approach and identifying cardiac tissue prior to ablation.

摘要： A grasper is provided having a handle with an elongated shaft secured thereto. First and second jaw members with opposed clamping surfaces are secured to the shaft, with one jaw member being slidably secured with respect to the other jaw member. The jaw members are relatively movable by an actuator between an open position and a closed position. A resilient member is associated with at least one of the first or second jaw members or the actuator limits the force exerted on tissue held between the clamping surfaces of the jaws when the jaws are in the closed position. The jaws are preferably, but not necessarily, pivotal relative to the elongated shaft by remote actuation.

摘要： A method and apparatus for transmural ablation using an instrument containing two electrodes or cryogenic probes. A clamping force is exerted on the two electrodes or probes such that the tissue of the hollow organ is clamped therebetween. Bipolar RF energy is then applied between the two electrodes, or the probes are cryogenically cooled, thus ablating the tissue therebetween. A monitoring device measures a suitable parameter, such as impedance or temperature, and indicates when the tissue between the electrodes has been fully ablated.
