Percutaneous Puncture of the Radial Artery with a Multi‐Purpose Teflon Catheter for Indwelling Use

Barr P.‐O. Percutaneous puncture of the radial artery with a multipurpose Teflon catheter for indwelling use. A Teflon catheter assembly is described, which was designed for percutaneous insertion and indwelling use in the radial artery, and in other superficial blood vessels with calibers of a similar order of magnitude. The advantages of the instrument, which may also be used for percutaneous puncture of other superficial tissues and organs, are reported and discussed, especially with regard to the preferential choice of the radial artery for arterial punctures.
