Abstract
An imaging device such as a catheter has a plurality of infusion holes adapted to infuse liquid into the blood stream while substantially preventing radial jetting. An example imaging catheter includes an elongated member, having distal and proximal ends, an axis, a lumen along the axis, and an outer surface. Preferably, a plurality of infusion holes are defined along the axis of said elongated member between the lumen and the outer surface. The plurality of infusion holes may be tapered from the outer surface to the lumen. Further, the plurality of infusion holes may be angled outwardly toward the proximal end of the elongated member. The size, shape, spacing and configuration of the infusion holes may be varied as desired.
