This invention relates to catheters, and more particularly to Foley, indwelling or self-retaining catheters. Disclosed are particular drainage port positions along the catheter and anchor shapes that facilitate complete drainage of a hollow organ or bladder in which the catheter is inserted. Methods described herein may prevent the pathological expansion of a balloon anchor member portion of an indwelling catheter from being deployed and expanded prior to advancing in the bladder and beyond the urethra.
