First Claim
Patent Images
1. A tool for use with a catheter to aid in forming a guidewire exit site by a medical practitioner comprising:
- a body portion having a central bore adapted to slidably receive the catheter such that the tool is positionable at a desired location on the catheter; and
a manually operated actuation mechanism associated with the body portion that is adapted to be angularly displaced relative to the central bore of the body portion and to engage the catheter to form a guidewire exit site that is angled relative to the central bore of the body portion at the desired location on the catheter in such a manner that the guidewire exit site is operable to direct the guidewire to exit the catheter at the guidewire exit site without damage to the catheter by kinking, the activation mechanism forming the guidewire exit site when activated by the medical practitioner.

18. A medical system comprising:
-
a catheter having a guidewire lumen and including an outer wall surrounding the guidewire lumen; and a tool having a first portion defining a bore for receiving the catheter and a second portion manually displaceable relative to the first portion to angularly displace a portion of the catheter for forming an angled guidewire exit through the outer wall of the catheter that is angled relative to the bore of the first portion of the tool. - View Dependent Claims (19, 20, 21)
