Abstract

A catheter (10) provided with a guidewire catheter lumen (18) having a thin covering (102) that is easily punctured by a guidewire (19) at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. The covering is also preferably tear resistant at puncture sites. Materials suitable for the catheter shaft are polymeric materials well known in the art; the catheter shaft may optionally be provided with metallic stiffening components such as wires or hypotubes along all or part of the catheter length.
