摘要： The present invention is directed to an active handle assembly for use in a bidirectional steerable surgical instrument having a deflectable distal end. Typically, the surgical instrument includes a handle component which the user manipulates to cause a distal end of the instrument to deflect. The distal end comprises an end tip portion of a shaft which extends outwardly from the handle. A control mechanism is disposed within the handle and extends through the shaft for selectively controlling the direction and degree of deflection at the distal end. For example, one exemplary control mechanism uses control or steering wires to deflect the distal end. The active counterforce mechanism according to the present invention is designed to be used in combination with the control mechanism and provides a force which counters the return to center force generated by the deflection of the shaft at the distal end thereof. Optimally, the active counterforce mechanism balances the return to center force across the instrument's deflection range in distal and proximal directions. This results in the user experiencing minimal, if any, resistance during the manual manipulation of the control mechanism.

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： 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.
