Abstract
An anchoring system for a urethral catheter (14, 36), and a method of its use, involve a resilient anchor-interval portion (40) of a catheter drainage shaft (42, 42'), positioned between a bladder balloon (26) and a urethral anchoring cuff balloon (44). The anchor-interval portion has a sinusoidal configuration lengthwise thereof which provide a proper linear elastic resilience for allowing the bladder balloon and the urethral anchoring cuff balloon to be separated a substantial distance for impinging against what remains of a prostate gland (20, 28, 32).
