Claim 0:
1. A dialysis sheath for use with a catheter that cleans obstruction from a dialysis flow tube used for dialysis of a patient, comprising:
a main hollow body having a lower portion for insertion into an opening of the dialysis flow tube, the main hollow body for guiding the catheter that enters into the dialysis flow tube for cleaning obstructions;
a fluid passage extending along the main hollow body; and
a fluid-actuated stop mechanism positioned within the lower portion of the main hollow body, the fluid-actuated stop mechanism being in communication with the fluid passage, the fluid-actuated stop mechanism being actuatable to transition between (i) a first position in which the stop mechanism is adjacent to or within a surface of the lower portion of the main hollow body, and (ii) a second position in which the stop mechanism expands to radially protrude away from the main hollow body so as to be configured to engage an inner surface of the dialysis flow tube directly adjacent to the opening to maintain the lower portion of the main hollow body within the dialysis flow tube, and
wherein, in response to the fluid-actuated stop mechanism being in the second position, the fluid-actuated stop mechanism is configured to anchor the lower portion of the main hollow body within the dialysis flow tube while the dialysis sheath is being manipulated to change a direction of the lower portion.
