1. A body cavity irrigation and drainage system comprising:
a catheter apparatus configured to be inserted into a pleural space of a patient, the catheter apparatus comprising:
a body comprising a longitudinal axis and an inner surface that defines a cavity, the body being integrally formed as a monolithic structure;
an internal wall located within the cavity that divides the cavity into a first flow channel and a second flow channel that are fluidly isolated from one another;
wherein the body is alterable between: (1) a first state in which a distal portion of the body is elongated along the longitudinal axis; and (2) a second state in which the distal portion of the body is separated into a first tail portion that curls away from the longitudinal axis in a first direction and a second tail portion that curls away from the longitudinal axis in a second direction that is different than the first direction; and
wherein the first tail portion defines a first distal portion of the first flow channel and the second tail portion defines a second distal portion of the second flow channel;
an irrigation source operably coupled to the first flow channel of the catheter apparatus and 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 and 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.
