ABSTRACT:
This invention relates to a process of making a shaped tip on a catheter. In this process, a lubricant solution is placed on a catheter, the catheter is placed on a mandrel, the catheter is heated, and the mandrel is engaged with a die to form a shaped tip on the catheter. The tipping lubricant of this invention comprises water as the solvent. The lubricant is a silicone surfactant, which is non-ionic and which is a good lubricating fluid. The lubricant solution into which the catheter is dipped includes low percentages of a solution stabilizer and an antimicrobial agent to clarify the solution and to inhibit microbial growth in the water solution. Vitamin E or its derivative may also be used in the lubrication solution.
