1. A catheter drainage member configured to be attached to a catheter tube, the drainage member comprising:
a body having an inner surface and a longitudinal axis extending between a proximal end of the body and a distal end of the body;
a non-symmetrical well defined by the inner surface of the body, the body having an end wall with a proximal opening configured to receive the catheter tube and an adhesive into the non-symmetrical well, the inner surface of the body having a tapered portion extending outwardly from a shoulder at a distal end of the non-symmetrical well to the end wall at a proximal end of the non-symmetrical well, and the non-symmetrical well having a cross-section that is non-symmetrical in a plane that is perpendicular to the longitudinal axis of the body and parallel to the end wall of the body, the cross-section having a narrower side and a wider side; and
wherein the well is configured to selectively distribute the adhesive between the inner surface and the tube.
 
5. A urinary catheter, comprising:
a catheter tube; and
a drainage member attached to a distal end of the catheter tube, the drainage member comprising:
a body having an inner surface and a longitudinal axis extending between a proximal end of the body and a distal end of the body;
a non-symmetrical well defined by the inner surface of the body, the body having an end wall with a proximal opening configured to receive the catheter tube and an adhesive into the non-symmetrical well, the inner surface of the body having a tapered portion extending outwardly from a shoulder at a distal end of the non-symmetrical well to an end wall at a proximal end of the non-symmetrical well, and the non-symmetrical well having a cross-section that is non-symmetrical in a plane that is perpendicular to the longitudinal axis of the body and parallel to the end wall of the body, the cross-section having a narrower side and a wider side; and
wherein the well is configured to selectively distribute the adhesive between the inner surface and the tube.
