摘要： A process and product and apparatus are disclosed wherein a laser is used to form a conical tapered tip on a catheter product. The catheter is placed on an insertion needle prior to the formation process, thus eliminating the problems associated with wearing out forming tooling. The process and product further call for the use of the laser to create a surface effect on the cannula to indicate the terminus of the catheter.

摘要： A process is provided wherein a laser is used to shape and/or trim a polymer tubular catheter material while in situ on a metal insertion needle or cannula. The laser process seals the interface between the polymer catheter material and the metal cannula to prevent the flow of blood between the tubular catheter and the introducing cannula during insertion into a patient. The interface is of sufficient strength to resist such blood flow, but still sufficiently weak to prevent the removal of the cannula needle after insertion into a patient.
