  • Publication number: 20080097499
    Abstract: 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.

  • Publication number: 20070282303
    Abstract: 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.

  • Publication number: 20060282015
    Abstract: 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 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 introducing a sealing member into the open end of said 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.

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.

  • Publication number: 20050075647
    Abstract: An attachment tool to facilitate the attachment of a catheter or similar elongated instrument to a guide-wire or other elongated guide member, without requiring access to either end of said wire or member. Said tool providing repeatable and reliable alignment of components to be attached. In an embodiment, the attachment tool may be integrated into an introduction port or valve. In another embodiment, the attachment tool is a separable tool that may be employed for the purpose of placing a catheter onto a guide member.
