1. A method of removing fluid from a subject, comprising the steps of:
(a) inserting the distal region of the shunt device into a bodily space of a subject; wherein the shunt device has:
(i) an outer tube member forming a first lumen, the outer tube member having a drainage outlet and at least one opening to the first lumen in a distal region along a length of the outer tube member;
(ii) an inner tube member forming a second lumen, the inner tube member having at least one opening to the second lumen along the length of the inner tube member, wherein the inner tube member is positioned within the first lumen; and,
(iii) a pump unit fluidly connected to the second lumen;
(b) positioning the at least one opening along the length of the outer tube member within a region of the bodily space;
(c) drawing fluid from bodily space through the at least one opening along the length of the outer tube member and into the first lumen;
(d) upon determining that the at least one opening along the length of the outer tube member is obstructed, activating the pump unit to inject a fluid into the second lumen to generate enough pressure within the first lumen to force the fluid from the first lumen out through the at least one opening along the length of the outer tube member, thereby clearing the obstruction; and
(e) deactivating the pump unit to permit drawing the fluid from a bodily space through the at least one opening along a length of the outer tube member and into the first lumen.
