Abstract
In a catheter system for rapid exchange via a guidewire with a flexible, elongated inner catheter, which has a proximal end and a distal end as well as a guidewire lumen, which extends from an insertion port on the distal end to a lateral through port distally from the proximal end, and a flexible, tubular outer catheter, in which the inner catheter is disposed axially displaceably, and which has a lateral exit port for the guidewire, retaining means are provided on the inner catheter and the outer catheter, which retaining means prevent twisting of the outer catheter relative to the inner catheter. Thus, the through port and the exit port remain aligned with each other and the catheter system can be displaced simply along the guidewire. In addition, the outer catheter can be readily displaced relative to the inner catheter.
