1. A suction catheter apparatus, comprising:
a tubular body having a proximal end portion and a distal end portion, and a suction opening at the distal end portion for collecting material from a region external to the distal portion, the tubular body defining at least first and second lumens extending from the proximal end portion to the distal end portion, each of the first and second distinct lumens in fluid communication with a chamber defined within the distal end portion of the tubular body, the chamber being in fluid communication with the suction opening, the distal end portion of the tubular body defining a longitudinal axis coincident with or parallel to a central axis circumaxially around which is formed a side wall of the tubular body;
a tube extending from the first lumen of the tubular body into the chamber and defining a tube channel and an emission opening in fluid communication with the tube channel, the tube being substantially U-shaped in the chamber, wherein the emission opening is positioned and oriented in combination with the tube channel to direct fluid flow from the tube channel into an emission jet that is flowable within the chamber and past the suction opening in a flow path that is skewed relative to the longitudinal axis;
a connector secured to the proximal end portion of the tubular body and having an inlet coupling portion and an outlet coupling portion, the inlet coupling portion having an inlet lumen in fluid communication with the first lumen of the tubular body, and the outlet coupling portion having a separate outlet lumen in fluid communication with the second lumen of the tubular body;
a pump for delivering pressurized fluid from a fluid reservoir to the chamber through the inlet lumen, the first lumen, and the tube channel; and
a collection chamber in fluid communication with the outlet lumen for collecting the material through the second lumen.
