摘要：
Catheter having a proximal section and a distal section. The proximal section having at least a delivery lumen and a guidewire receiving lumen, the guidewire receiving lumen having a proximal guidewire exit port at a location proximal of the distal end of the proximal section. A reinforcing tubular member located in the proximal section delivery lumen extending from substantially the proximal end of the proximal section to a point distal to the proximal guidewire exit port, wherein the reinforcing tubular member transitions from relatively rigid to relatively more flexible from a proximal point to a distal point thereon and has an outer diameter equal to about the inner diameter of the delivery lumen for at least a portion of the reinforcing tubular member that extends distal to the proximal guidewire exit port. The distal section having at least a delivery lumen and a guidewire receiving lumen.
