Mechanical thrombus maceration device

(57) [Abstract] The present invention provides the mechanical medical device which is useful in order to 浸軟 a thrombus or an equivalent. In one example of the present invention, a present instrument implement has a rotor (50) held at the tip of a housing (70), and this housing has at least one port (74, 75) discharged through a fluid. A size is decided and one or more ports which can be set in this example are positioned so that each port may not be arranged equally at the circumference of the circumference of a housing. For example, the housing may include which [of the port beyond two which took the interval un-conformally, or it] case in the circumference of the circumference of a housing with two which took the interval conformally with the single port or a different size, the port beyond it, or the same size. When a fluid is discharged from these ports, a housing inclines toward the direction of the one side of a blood vessel. In other examples, a present instrument implement takes an interval in accordance with a common axis (10), and contains a plurality of rotors (50A, 50B, 50C) rotated with an axis. In the 3rd example of the present instrument implement, in order to return the fluid discharged from one port in a housing to the direction of a rotor, the fluid inclination means (for example, 240) is established.
