1. In a two-step introduction assembly for implanting an introducer catheter within a patient to provide a path for introduction of a primary device, whereby the introducer catheter may be removed and discarded while the primary device remains in operative position, the assembly including a needle for venipuncture and a peelable introducer catheter over the needle having at least one longitudinal rupture means for substantially its entire length along which the catheter may be ruptured, the improvement comprising:

  • (a) a slidable sleeve snuggly engaging the introducer catheter tube having a proximal end and a distal end and slidably mounted about the proximal end of the catheter to protect the catheter from inadvertent separation along the rutpure means and being slidable to the distal end of said catheter tube under the influence of manual disruption of the catheter tube along the rupture line from the proximal end, whereby the introducer catheter tube may be discarded after disruption along the rupture line while the sleeve remains in position on the primary device as a securing site; and

    (b) a securing ring snuggly engaging the introducer catheter and needle at the proximal end of the catheter and needle, said ring being affixed to said catheter and needle so as to prevent rotation of the catheter with respect to the needle during implantation and being sufficiently weak that it may be broken under the influence of manually applied pressure.
