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 provides 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).

11. The method as in claim 10 wherein the step of providing a catheter drainage shaft includes the substep of making said anchor interval portion to have a corrugated shape.
12. The method as in claim 10 wherein is further included the step of inserting a guide wire in the drainage shaft for extending the anchoring internal portion before said indwelling urethral catheter is mounted in said urethra.
13. An urethral sizing catheter comprising: a catheter drainage shaft constructed of non- separable parts, defining an enclosed drainage canal through which urine can flow, for extending through and being anchored in, a urethra so that an upstream end is positioned in a patient's bladder and a downstream end extends beyond a urethral meatus; an anchoring system mounted on said drainage shaft for anchoring said drainage shaft in said urethra for preventing downstream and upstream migration of said drainage shaft, said anchoring system including: a urethral anchoring member mounted on said catheter drainage shaft at a position spaced downstream of said upstream end of said catheter drainage shaft for distending in a bulbous urethra of said urethra for anchoring said catheter drainage shaft in said bulbous urethra, with said urethral anchoring member having freedom of movement both upstream and downstream relative to the bladder so that it can find this proper anchoring position in said bulbous urethra, wherein said catheter drainage shaft, extending downstream from said urethral anchoring member to said downstream end is made of non-separable parts.
14. The urethral sizing catheter as in claim 13 wherein said urethral anchoring member is a balloon.
15. The urethral sizing catheter as in claim 13 wherein is further included: a bladder anchoring member mounted at the upstream end of said catheter drainage shaft for engaging said bladder and thereby contacting a bladder wall for deterring downstream migration of said catheter drainage shaft in said urethra; and, an anchor- interval portion of said catheter drainage shaft, positioned between said bladder anchoring member and said urethral anchoring member, has an elastic resilience for allowing said bladder and urethral anchoring members to separate a substantial distance and for thereafter biasing the bladder and urethral anchoring members toward one another for impinging against opposite sides of prostatic tissue located between the bladder and urethral anchoring members .
16. The urethral sizing catheter as in claim 15 wherein said anchor- interval portion is of a size so that said bladder and urethral anchoring members will be biased against sides of the prostatic tissue.
17. The urethral sizing catheter as in claim 13 wherein said urethral sizing catheter is a male urethral sizing catheter and wherein said catheter drainage shaft has a length such that its downstream-most end lies downstream of a penile meatus.
18. The urethral sizing catheter as in claim 13 wherein said catheter drainage shaft has thereon graduated indicia positioned along a downstream portion thereof where said drainage shaft extends from the urethral meatus.
19. A method of anchoring a urethral catheter comprising the steps: providing a catheter shaft having a bladder anchoring member at an upstream end portion thereof and a urethral anchoring cuff mounted on said catheter shaft downstream of said bladder anchoring member, wherein an anchoring interval portion of said catheter drainage shaft, between said bladder anchoring member and said urethral anchoring cuff, is substantially elastic for allowing said bladder anchoring member and said urethral anchoring cuff to be linearly distanced from one another and for thereafter applying a bias to said bladder anchoring member and said urethral anchoring cuff for retracting said bladder anchoring member and said urethral anchoring cuff linearly toward one another ; mounting said urethral sizing catheter in a urethra by distending said bladder anchoring member in the patient's bladder and the urethral anchoring cuff in the patient ' s bulbous urethra and thereby causing said bladder anchoring member and said urethral anchoring cuff to separate from one another while stretching said anchoring interval portion so that said anchoring interval portion biases said bladder anchoring member and said urethral anchoring cuff against opposite sides of tissue.
