The available documentation is largely due to the efforts of early Catholic missionaries, summarized by Paul Rivet.
Laser machining polyether block amide tubing: polyether block amide (PEBA) is used successfully in a range of catheter designs. This article describes how PEBA's compatiblity with laser machining can simplify catheter manufacturing, for example, transforming single durometer extrusions into multidurometer shafts more easily than with other fabrication methods.(MATERIALS)
