摘要： A device suitable for removing material from a living being is provided, featuring an infusate pump, and an aspiration pump, both powered by a motor. The aspiration pump and infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. 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：提供了一种适用于从活体中去除材料的装置，其特征在于具有输注泵和吸引泵，两者都由马达驱动。抽吸泵和输注泵优选地具有螺旋泵送机构，并且以高转速进行操作，从而确保足够的泵送性能和柔性。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 open end of the tubular guide wire to 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： An apparatus for modulating the pressure of a fluid such as a gas within the expandable portion of a guide wire catheter. The apparatus features a means for controllably gripping and releasing the open, proximal end of a tubular guide wire, means 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 means for sealing the open end of said tubular guide wire to seal the fluid in the tubular guide wire. In a preferred embodiment, the apparatus also features a deflation tool for re-opening the sealed tubular guide wire and letting the fluid out. In a particularly preferred embodiment, the pressure and volume of fluid in the tubular guide wire is maintained by utilizing an apparatus to crimp the end of the tubular guide wire, effectively sealing the inside bore of the tubular guide wire. Here, a deflation tool might comprise a means of severing the crimp from the rest of the tubular guide wire, unsealing the bore of the tubular guide wire. Preferably, the crossing profile of the crimped tubular guide wire is no greater than what it was prior to crimping. Using this apparatus, the tubular guide wire can be re-sealed and re-opened as necessary.
