Abstract
A catheter including a tubular catheter body defining a distal portion, a distal end and a lumen that extends to the distal end, a radiopaque marker carried within the lumen, and a non-metal tip that is bonded to distal end of the catheter body.
Claims16
A method of making a catheter, comprising:
- providing a catheter body having a distal end and defining a lumen therethrough;
- inserting a radiopaque marker into the lumen of the catheter body, wherein inserting the radiopaque marker into the lumen comprises extending a portion of the radiopaque marker out from the distal end of the catheter body;
- providing an abutment in the lumen of the catheter body, the abutment configured to transfer force from a stylet to the catheter body and to prevent the stylet from directly engaging the radiopaque marker;
- and
- after the radiopaque marker has been inserted into the catheter body lumen, providing a non-metal tip on the distal end of the catheter body, wherein providing the non-metal tip on the distal end of the catheter body comprises receiving the portion of the radiopaque marker in an indentation in the non-metal tip.
