ABSTRACT:
A placement device for a catheter and guide wire comprising, a valve assembly having a proximal end, a distal end for connection to the catheter, an elastic valve member having a least one slit and a slide member being slidably received in the valve assembly and being movable between a first position spaced from the valve member with the valve member being closed, and a second position engaged against the valve member with the valve member being open, with the slide member having a bore extending therethrough. The device has a valve opener having an elongated stem on an end of the opener with an outer diameter sufficiently small to be received in the bore of the slide member, with the stem having sufficient length to extend through the slide member and open the valve member with the valve opener extending through the valve member, and with the stem having a channel with an inner diameter sufficiently large to receive the guide wire.
