Patent ID: 8241256

Claim:
A needle guide for a needle-based medical device, the needle guide comprising: a body for insertion into a distal end of a first lumen of a tube, the body including an outer surface at a first radial distance from a longitudinal axis of the body and a second lumen to position a proximal end of a needle; at least two ribs extending longitudinally in a distal direction beyond a distal end of the body, each of the at least two ribs radially distanced from the longitudinal axis of the body by a second radial distance, the second radial distance being greater than the first radial distance, so as to create a first annular space between the first lumen of the tube and the outer surface of the body; and a flange coupled to a distal end of the at least two ribs, wherein a radially outer surface of the flange is distanced from the longitudinal axis of the body by a third radial distance, the third radial distance being greater than the second radial distance.
