Catheter and guidewire exchange system with improved catheter design
First Claim
1. A catheter guiding assembly, comprising:
- a catheter, comprising;
an elongate shaft having an exterior surface, a proximal end, and a distal end, a first lumen extending through the shaft from the shaft proximal end to the shaft distal end, and sized to receive a guidewire, and a guideway extending from the shaft proximal end to the shaft distal end, and enabling transverse access from the shaft exterior surface to the first lumen; and
a catheter advancing and retracting apparatus, comprising;
an elongate housing having a proximal end and a distal end, an opening formed through the housing from the housing proximal end to the housing distal end and adapted to receive the catheter, a wheel port formed in the housing between the housing proximal and distal ends and in communication with the opening, and a wheel secured in the wheel port and sized to radially extend into the catheter guideway when the catheter is received in the opening.

Abstract
A catheter guiding assembly includes a catheter and a catheter advancing and retracting apparatus. The catheter includes an elongate shaft having an exterior surface, a proximal end, and a distal end; a first lumen extending through the shaft and sized to receive a guidewire; and a guideway enabling transverse access from the shaft exterior surface to the first lumen. The catheter advancing and retracting apparatus comprises an elongate housing having a proximal end and a distal end; an opening formed through the housing and adapted to receive the catheter; a wheel port formed in the housing and in communication with the opening; and a wheel secured in the wheel port and sized to radially extend into the catheter guideway.
