<p>A stylet wire assembly (10) sealingly engages the proximal end (22) of a medical catheter (20), and includes a stylet wire (11) and a housing (12). The housing (12) has a catheter fluid communication port (13) at its distal end and anchors the stylet wire (11) into its closed proximal end with the stylet wire (11) extending through the catheter fluid communication port (13). An external fluid communication port (15) allows for fluid communication into and out of said housing (12) in transverse orientation relative to the stylet wire (11) and distally of the anchoring of the stylet wire into the proximal end of the housing. The housing (12) sealingly engages a medical catheter (20) in fluid communication between the catheter fluid communication port (13) of housing (12) and the fluid conduit of catheter (20) by means of the combined effect of a female threaded portion (17) which advances over the end of catheter (20) and an inner sealing tubular portion (18) which advances within the catheter.</p> |
