The invention relates to the field of
medical instruments, and particularly discloses an implantable
catheter, a use method and a preparation method thereof. The implantable
catheter comprises a
catheter body with a near end and a far end, wherein the catheter body is internally provided with a guide wire cavity channel, an inflation cavity channel and a guide wire cavity channel which are independent of one another, and a guide wire is arranged in the guide wire cavity channel; a
pressure sensor arranged on the tube body, connected with the lead in the lead cavity and used for monitoring the pressure of the implanted tissue in real time; and a
balloon arranged on the tube body and communicated with the inflation cavity channel. The
pressure sensor is integrated on the catheter body, so that the pressure in the implanted tissue is directly measured, the structure of the catheter is simplified, and the
diameter of the catheter is reduced.
