  • Patent number: 8545447
    Abstract: Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body and a clearing element for preventing buildup of materials at the opening of the catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor fainted over an outer surface thereof. The clearing element may comprise a free end of a structure near the distal end of the catheter body for disrupting clot, wherein the free end of the structure extends into the distal opening of the catheter body to break up materials as the impeller is rotated. Alternatively, the clearing element may comprise a cutting member disposed at the distal opening of the catheter body.
    Type: Grant

  • Patent number: 6702830
    Abstract: Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor formed over an outer surface thereof. Optionally, in the case of a tubular shaft, a second helical rotor may be provided within the shaft lumen in order to induce flow in opposite or in the same direction as induced by the outer helical rotor. Catheters may further comprise structures near their distal ends for disrupting clot, and are preferably introduceable over guidewires where the helical rotors are rotated directly over the guidewire. The catheters may include two or more impellers or impellers having two or more rotors in order to provide for circulation of materials at a target site within a patient body lumen.
