Locking brakes for enteral feeding tube retention member

An indwelling medical device comprising:

• an indwelling tube having a distal end and a proximal end, where the distal end is insertable into a patient's body;
• a plurality of projections longitudinally spaced along the indwelling tube at a predetermined distance from one another, wherein each projection of the plurality of projections does not completely surround an external surface of the indwelling tube;
• a retention member comprising:
• a length extending axially, an outer perimeter, a bore disposed through the retention member in an axial direction, an inner diameter formed by the bore, and a projection passage;
• the bore being adapted to receive the indwelling tube, such that the indwelling tube extends past a proximal end and a distal end of the retention member;
• the inner diameter formed by the bore has a magnitude less that a sum of a distance outwardly a projection of the plurality of projections extends and a diameter of the indwelling tube;
• and
• the projection passage extending the length of the retention member, the projection passage having a size and shape such that the plurality of projections can enter and pass through the projection passage when the projection passage and the plurality of projections are aligned.
