ABSTRACT:
The proximal end portion 29 of the relatively outer cannula 6 of the catheter 2 has a pusher tab 44 relatively radially upstanding on the cylindrical surface 32 thereof, which projects relatively radially outwardly from the cylindrical outline of the relatively outer cannula at the outer periphery thereof, to the extent that when a user grips the hilt 54 of the relatively inner cannula 4 with one hand 70 to advance the distal end portion 36 of the relatively outer cannula into a vein 80 or other passage and disengage the relatively inner cannula from the bore of the relatively outer cannula, he/she can apply one finger of his/her one hand, such as the index finger 72 thereof, to the tab, to drive the relatively outer cannula relatively forward toward the puncture 98 in the skin 78. The tab is limited in angular extent about the axis of the relatively outer cannula, however, so that after it has been angularly oriented about the axis 38 of the relatively outer cannula to upstand at a location opposite the skin for the advancement and insertion step, the relatively outer cannula can be rotated about its axis to lay the tab over against the skin while a strip of adhesive tape 96 or the like is applied over the tab to secure the relatively outer cannula to the skin, both lengthwise and crosswise of the axis, as well as rotationally thereof.
