Individual operator - exchange catheter with a distal catheter shaft section

摘要

The catheter includes a proximal tubular member, which may be connected to a transition tube, such tube or tubular member having an intermediate side port 214 to which the proximal end of a distal catheter shaft section 202 is connected. The section extends distally through an inflatable balloon 20 and forms a lumen 206 extending from the port to the distal end of the catheter for receiving a guide wire. To provide for fluid communication between the tubular member or transition tube and the interior of the balloon, inflation holes 220 are provided in the distal catheter shaft section and holes 222 within the balloon. Seals are provided in the distal catheter shaft section proximally of the first set of inflation holes and distally of the second set of inflation holes to allow such lumen to be utilized for both inflating the balloon and passing the guide wire without fluid leakage.
