Thrombus resolving treatment apparatus
First Claim
1. A thrombus resolving treatment apparatus for resolving a thrombus by radiating a therapeutic ultrasonic wave on a thrombus portion located in a blood vessel of a patient'"'"'s body in which a thrombus resolvent is injected, comprising:
- an ultrasonic radiator for radiating a therapeutic ultrasonic wave on said thrombus portion;
an ultrasonic probe for obtaining tomographic image data of an interior of said patient'"'"'s body;
a first ultrasonic imaging unit for visually displaying the tomographic image data supplied from said ultrasonic probe;
a catheter which is inserted into said blood vessel;
an ultrasonic transducer, mounted on said catheter, for obtaining tomographic image data of an interior of said blood vessel; and
a second ultrasonic imaging unit for visually displaying the tomographic image data supplied from said ultrasonic transducer;
said apparatus further comprising;
calculation means for calculating a value representing an effect of a thrombus resolving treatment on the basis of the tomographic image data supplied from said ultrasonic transducer;
identification means for identifying whether or not said value has reached a predetermined value; and
means for stopping radiation of the therapeutic ultrasonic wave by said ultrasonic radiator when the value calculated by said calculation means has reached said predetermined value.

9. A thrombus resolving treatment apparatus for resolving a thrombus by radiating a therapeutic ultrasonic wave on a thrombus portion located in a blood vessel of a patient'"'"'s body in which a thrombus resolvent is injected, comprising:
-
an ultrasonic radiator for radiating a therapeutic ultrasonic wave on said thrombus portion; an ultrasonic probe for obtaining tomographic image data of an interior of said patient'"'"'s body by transmitting and receiving an ultrasonic wave having a predetermined frequency; a first ultrasonic imaging unit, connected to said ultrasonic probe, for visually displaying the tomographic image data supplied from aid ultrasonic probe; a catheter which is inserted into said blood vessel; an ultrasonic transducer, mounted on said catheter, for obtaining tomographic image data of an interior of said blood vessel by transmitting and receiving an ultrasonic wave having a frequency different from that of the ultrasonic wave transmitted and received by said ultrasonic probe, and for detecting the ultrasonic wave transmitted from the ultrasonic probe, wherein said ultrasonic transducer comprises at least one strip-shaped piezoelectric element provided along a longitudinal direction of said catheter and having the dimensions of thickness, length in a circumferential direction of said catheter, and length in an axial direction of said catheter, any two of said dimensions being selected so as to correspond to a frequency of the ultrasonic wave transmitted from and received by said ultrasonic transducer and to a frequency of the ultrasonic wave transmitted from and received by said ultrasonic probe, respectively, and wherein the remaining dimension of said piezoelectric element is selected so as to correspond to a frequency of the ultrasonic wave radiated by said ultrasonic radiator; a second ultrasonic imaging unit, connected to said ultrasonic transducer, for visually displaying the tomographic image data supplied from said ultrasonic transducer; position detection means, connected to said ultrasonic transducer, for processing an ultrasonic wave signal output from said ultrasonic probe upon receipt from said ultrasonic transducer, thereby detecting a position within said blood vessel of said catheter; and means for displaying a detected result of said position detection means on a display screen of said first ultrasonic imaging unit.
