Abstract
In a self-retaining catheter in which a leading end of the catheter can be fixed to an inner wall of a tubular organ such as a blood vessel, a wire with higher stiffness than a catheter body and in a winding shape greater than an outside diameter of the catheter body is mounted inside a leading end of the catheter body or in a projecting state from the leading end of the catheter body. An aperture of a slit shape is formed in a peripheral wall of the catheter body, in order to allow a medical fluid to flow out therethrough. A self-retaining catheter inserting apparatus includes the above-stated self-retaining catheter, a core wire arranged to be inserted into and withdrawn from the self-retaining catheter, a master catheter through which the self-retaining catheter can pass, and a sheath necessary for the master catheter to be inserted into a tubular organ, and preferably, the apparatus further includes a medical fluid injection port.
