Abstract:
A stylet assembly for use with a catheter, the stylet assembly comprising:a stylet body to be received within the catheter, the stylet body having a proximal end and a distal end and comprising a piece of wire bent double and twisted together to form a rounded end at the distal end thereof, the stylet body being bent adjacent the distal end thereof, forming an offset distal end portion for facilitating correct placement of the catheter into a desired place in a blood vessel; anda stylet connector for connecting the stylet assembly to the catheter, the stylet connector comprising (1) a tubular member having an inflow port at a proximal end thereof and a flow passage extending through the tubular member between the inflow port and a distal end of the tubular member, the tubular member also having at the distal end thereof a connecting portion including (1a) a central through-hole in which the proximal end of the stylet body is fixedly held and (1b) at least another flow passage within the tubular member around the central through-hole and the proximal end of the stylet body, whereby fluid introduced at the inflow port can flow through the tubular body and into a coupled catheter without removal of the stylet body and (2) means for coupling with the catheter to prevent a coupled catheter from separating from the stylet connector during use.
