Body cavity irrigation and drainage system

A system for irrigating and draining a pleural space of a patient, the system comprising:

• a catheter apparatus comprising:
• a tubular body having an inner surface that defines a cavity, a proximal end, a distal end, and a longitudinal axis extending between the proximal and distal ends;
• a divider wall having a first end connected to the inner surface of the tubular body on a first side of the longitudinal axis and a second end connected to the inner surface of the tubular body on a second side of the longitudinal axis;
• the cavity separated by the divider wall into a first flow channel defined by a first surface of the divider wall and a first portion of the inner surface of the tubular body and a second flow channel defined by a second surface of the divider wall and a second portion of the inner surface of the tubular body, the second flow channel being fluidly isolated from the first flow channel between the proximal and distal ends of the tubular body;
• wherein the catheter apparatus is alterable between:
• (1) a first state in which the first and second flow channels are linear and parallel to the longitudinal axis along an entire length of the first and second flow channels from the proximal end to the distal end;
• and (2) a second state in which a distal portion of the first flow channel curls away from the longitudinal axis in a first direction and a distal portion of the second flow channel curls away from the longitudinal axis in a second direction that is different from the first direction:
• an irrigation source operably coupled to the first flow channel of the catheter apparatus, wherein the irrigation source is configured to introduce a fluid into the pleural space through the first flow channel;
• a suction source operably coupled to the second flow channel of the catheter apparatus, wherein the suction source is configured to apply suction to the pleural space through the second flow channel;
• and
• wherein the first and second flow channels are fluidly isolated from one another such that the fluid is configured to be introduced into the pleural space through the first flow channel simultaneously with the suction being applied to the pleural space through the second flow channel.
