First Claim
Patent Images
1. A system for delivering and deploying a medical device within a patient, the system comprising:
- a control handle;
a catheter portion coupled to the control handle, the catheter portion including an inner member having a mounting region located near its distal end for carrying the medical device, the inner member being made from a single wire having a flat wire portion at a distal region and a proximal region attached to the handle, an outer catheter member coaxially disposed over at least a portion of the inner catheter member, the outer catheter member including a retraining sheath adapted to cover the medical device, the retraining sheath being movable by the control handle;
an inner guide wire lumen formed from a length of tubing extending proximally from the distal end of the inner member, the guide wire lumen having a first opening spaced apart from a second opening extending along the distal region of the inner member;
a distal tip coupled to the inner member;
wherein the flat wire portion of the inner member overlays at least a portion of the inner guide wire lumen.
