Abstract:
1. A needle and catheter assembly for insertion into a blood vessel comprising: a needle having a needle shaft and a needle tip extending distally from a proximal shaft junction, the needle tip defining a distal-most sharp point that is enclosed at a needle distal end; a side port in fluid communication with a lumen of the needle shaft located on a first side adjacent to the shaft junction, such that a surface of the side port extends continuously from a portion of the needle tip, through the shaft junction, and onto an adjacent portion of the needle shaft; an upwardly curved heel on the needle tip along a second side opposite the first side that extends from the shaft junction to the distal-most sharp point and thereby locates the point adjacent to a longitudinal axis of the shaft; and a catheter overlying the needle and having a catheter distal end located with respect to the needle tip so that at least a portion of the catheter distal end extends distally past the shaft junction with the side port being unobstructed by the catheter distal end so as to maintain the fluid communication with the lumen.
