Technic for non-surgical insertion of large polyethylene tubing into blood vessels.

Q1'TE independently of each other, the Q authors of this brief report developed a simple technic which, without the use of special equipment, allows the percutanleous insertion of large bore polyethylene tubing into 1)loo0( vessels. Certain features have beci used by others.' 'It is self-evident that the rigid poinit of a hly)oderlmic needle, though desirable for percutaneous insertion into blood vessels, constitutes an undesirable source of continuinog vascular trauma thereafter. In our technic, the needle serves only to eflect entry anld gruide the tubing into the vessel 's lumen. An importanlt difference froni the usual approach is that here the tubintg is inserted ar(oJ iid rather than througfh the needle.
