    • A device for penetrating tissue and removing a biological sample includes a biological sampling element to remove a biological sample. The biological sampling element includes a passage therethrough. The device further includes a penetrator positioned within the passage. The penetrator is energized in a repetitive manner to assist in penetrating tissue. The biological sample element can be adapted to remove a tissue sample or a biological fluid sample (for example, blood). A device for penetrating tissue and positioning a tissue resident conduit (for example, a catheter), includes a tissue resident conduit (for example, a catheter) including a passage therethrough; and a penetrator in operative connection with the catheter. A device for inserting a tissue resident conduit includes at least one component that is energized during penetration to assist in penetrating tissue. In one embodiment, the tissue resident conduit is flexible and the energized component is positioned or a forward end of the tissue resident conduit. The device can further include a mechanism for directing the penetration of the tissue resident conduit. A needle for penetrating tissue includes a first effector including a surface and at least one actuator in operative connection with the first effector. The actuator is adapted to cause motion of the first effector such that tearing of tissue takes place in regions where there is close proximity of tissue to the surface of the first effector.
    • 用于穿透组织并去除生物样品的装置包括用于去除生物样品的生物取样元件。 生物采样元件包括通过其中的通道。 该装置还包括定位在通道内的穿透器。 穿透器以重复的方式通电以辅助穿透组织。 生物样品元件可以适于去除组织样品或生物流体样品(例如血液)。 用于穿透组织并定位组织驻留导管(例如导管)的装置包括组织驻留导管(例如导管),其包括穿过其中的通道; 以及与导管可操作地连接的穿透器。 用于插入组织固定导管的装置包括至少一个在穿透期间被激发以帮助穿透组织的部件。 在一个实施例中,组织驻留导管是柔性的,并且通电部件被定位或组织固定导管的前端。 该装置还可以包括用于引导组织驻留导管穿透的机构。 用于穿透组织的针包括包括表面的第一执行器和与第一执行器可操作地连接的至少一个致动器。 致动器适于引起第一效应器的运动,使得组织的撕裂发生在组织靠近第一效应器的表面的区域中。

    • PROBLEM TO BE SOLVED: To provide a fluid delivery system equipped with a manual controller to feed back pressure in a fluid path to an operator tactually, and to provide a pressure isolation mechanism and an injector control mechanism. SOLUTION: A manual controller of an injector system includes an actuator to control the injector by force applied by the operator. The actuator gives the operator tactual feedback of pressure in the fluid path by connecting the fluid path to the fluid so as to permit fluid communication therebetween. The pressure isolation mechanism includes a first state generated when a lumen and an isolation port are connected and a second state generated when they are separated. A valve is usually in the first state and is switchable to the second state when fluid pressure in the lumen reaches predetermined pressure. A pressure transducer 980 can be connected to the isolation port of the pressure isolation mechanism so as to permit fluid communication therebetween. The fluid delivery system includes a manual syringe and the pressure isolation mechanism. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种配备有手动控制器的流体输送系统,以在流体路径中将压力反馈到操作者,并提供压力隔离机构和喷射器控制机构。 解决方案:喷射器系统的手动控制器包括致动器,以通过操作者施加的力来控制喷射器。 致动器通过将流体路径连接到流体来使操​​作者对流体路径中的压力进行触觉反馈,从而允许流体连通。 压力隔离机构包括当管腔和隔离端口连接时产生的第一状态和当它们分离时产生的第二状态。 阀门通常处于第一状态,并且当管腔内的流体压力达到预定压力时可切换到第二状态。 压力传感器980可以连接到压力隔离机构的隔离端口,以允许它们之间的流体连通。 流体输送系统包括手动注射器和压力隔离机构。 版权所有(C)2007,JPO&INPIT
