A catheter comprises an inner tubular member, a braided reinforcement layer, and a soft outer layer. The inner tubular member extends from a proximal end of the catheter to a first distal location. The braided reinforcement layer extends from the proximal end of the catheter to a second distal location which is usually located proximally from the first distal location. The soft outer layer extends from the proximal end of the catheter to a third distal location which is usually located distally of the first distal location. In this way, a catheter having a shaft region, a transition region, and a distal region, each with different strength and flexibility characteristics, can be obtained. Such catheter constructions are particularly useful for very small diameter access catheters.
