A stomal diverter device (10) includes a catheter (20), a stoma rod (80), and a bracket (100). The catheter includes a first tube (24) having an open end, a second tube (26) spaced from the first tube having a closed end, and a drain tube (28). The stoma rod is positioned between the first and second tubes and includes structure to releasably attach the stoma rod to the abdomen of the patient. The bracket is supported on the catheter and the stoma rod and defines a locking feature (110a, 112a) that is configured to engage a mating feature (84a, 86a) of the stoma rod to secure the catheter between the stoma rod and the bracket.
