Abstract
A catheter includes a catheter tube, internal and external retention bolsters and a retractable catheter tip. The retractable tip is in the form of a bolus which is extended to axial alignment with the tube for insertion. After insertion with a stylet or the like, removal of the stylet permits the tip to retract automatically and assume a position perpendicular to the axis with minimal protrusion into the corporeal space involved.
