Abstract
A stylet wire assembly is disclosed which sealingly engages the proximal end of a medical catheter, and allows the unobstructed injection or evacuation of fluids into or from a patient's body through the catheter while the stylet wire is in place therein. The disclosed assembly includes a stylet wire and a housing. The housing has a catheter fluid communication port at its distal end and anchors the stylet wire into its closed proximal end with the stylet wire extending through the catheter fluid communication port at the distal end of the housing. This anchoring is accomplished by means of a plug which has been injection molded about the crimped proximal end of the stylet wire and bonded to the distal end of the remainder of the housing. An external fluid communication port allows for fluid communication into and out of said housing in transverse orientation relative to the axis of said stylet wire within said housing and distally of the anchoring of the stylet wire into the proximal end of the housing. The distal end of the housing sealingly engages the proximal end of a medical catheter in fluid communication between the catheter fluid communication port of the housing and the f…
