摘要： A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal. The working head may be operated to separate and move away from the guide wire to come within a closer proximity of the obstructive material to more effectively remove it from the vessel.
摘要翻译：提供一种适用于从活体中去除材料的装置，其特征在于至少一个由马达驱动的抽吸泵。抽吸泵和任何可选的输注泵优选地具有螺旋泵送机构，并且以高转速进行操作，从而确保了足够的泵送性能和灵活性。螺旋泵送机构可以是围绕中心芯管的螺旋卷绕的线。螺旋线圈线，无论是与芯管一起，还是独立于芯管，可以旋转以引起泵送动作。另外，保持狭窄的横截面，确保装置可能达到脉管系统的更曲折的区域。在一个实施例中，系统包括导线单轨导管，其具有安装在导管的柔性部分上的工作头，所述工作头能横向移位远离引导线以促进血栓移除。工作头可以被操作以分离并远离引导线进入更靠近阻塞物质的位置，以更有效地将其从容器中移出。

摘要： An apparatus for modulating the pressure of a fluid such as a gas within the expandable portion of a guide wire catheter. A preferred embodiment apparatus features a mechanism for controllably gripping and releasing the open, proximal end of a tubular guide wire, a mechanism for introducing a fluid to a desired pressure and volume into the expandable portion of the tubular guide wire through the open end, and, while maintaining the pressure and volume of fluid in the tubular guide wire, a mechanism for introducing a sealing member into the chamfered, open end of the tubular guide wire to consistently seal the fluid in the tubular guide wire. In a particularly preferred embodiment, the apparatus also features a deflation tool for piercing the seal and letting the fluid out. Using this apparatus, the tubular guide wire can be re-sealed and re-opened as necessary.

摘要： Various embodiments of an offset catheter are provided. In some embodiments, an offset catheter includes a guidewire tube and a catheter coupled with an elastic and/or compressible rib. The compressible rib provides an offset or separation between the catheter and the guidewire tube in its resting state. The rib has an initial resting state, but may be forced into a compressed state. When released from the compressed state, the rib returns to its resting state. An offset catheter may be compressed and slid through a sheath. When the offset catheter emerges from the sheath, the distal tip will return to its resting state providing an operation offset.
