ABSTRACT:
A catheter assembly comprises an outer catheter comprising a distal end curved portion having a first curved shape, and an inner catheter which comprises a distal end curved portion having a second curved shape different from the first curved shape and which can be inserted into the outer catheter so that the distal end curved portion thereof is located in the distal end curved portion of the outer catheter and be withdrawn therefrom. The distal end curved portion of the outer catheter is more flexible than the distal end curved portion of the inner catheter. A distal end portion of the catheter assembly, when the inner catheter is inserted in the outer catheter so that the distal end curved portion of the inner catheter is located in the distal end curved portion of the outer catheter, assumes a curved shape different from the first curved shape.
