1. The method of controlling urine flow from the bladder in a body which includes the steps:
- a) providing an axially endwise elongated magnetically responsive cylindrical valve of a size to fit in the urethra, providing grip means at an end of the valve, and providing a valve actuating magnet,b) installing the valve in the urethra, by providing a tool having grip finger means and operating the tool to cause said finger means to grip said grip means for advancing the valve endwise in the urethra, in the path of urine flow,c) and operating the valve between urine flow passing and urine flow blocking states, by controlling the position of the actuating magnet, outside the body, whereby the magnetic field of the actuating magnet effects said operating of the valve.

Abstract
A method and device for controlling urine flow from the bladder in a body which includes providing a magnetically responsive valve of a size to fit in the urethra, and providing a valve actuating magnet; installing the valve in the urethra, in the path of urine flow; and operating the valve between urine flow passing and urine flow blocking states, by controlling the position of the actuating magnet, outside the body, whereby the magnetic field of the actuating magnet effects the operating of the valve.

5. The method of controlling body fluid flow in a body internal duct, which includes the steps:
-
a) providing an axially endwise elongated magnetically responsive cylindrical valve of a size to be inserted in series with said duct, and providing a valve actuating magnet, b) said valve provided to have a rotary valving element, with magnetic pole means thereon providing a magnetic field, c) inserting said valve in said duct, by providing a tool having grip finger means and operating the tool to cause said finger means to grid said grip means for advancing the valve endwise in the urethra, in the duct, d) and effecting rotation of the valving element between body fluid flow passing and flow blocking positions, by controlling the position of said actuating magnet, outside the body, thereby causing the magnetic field of the actuating magnet to interact with the magnetic field of the rotary valving element pole means. - View Dependent Claims (6)

7. In apparatus for controlling urine flow from a bladder in a body, the combination comprising
a) an endwise elongated magnetically responsive valve of a size to fit in series with the urethra in the body and to be responsive to a separate valve actuating magnet, b) the valve having a movable valving element with magnetic pole means providing a magnetic field, c) the valving element being movable between urine flow passing and urine flow blocking states, by controlling the position of the actuating magnet causing the magnetic field of the movable valving element pole means, d) there being grip means on the valve at one end thereof, the valve having a cylindrical outer surface, the grip means located within a cylinder defined by said surface, to be gripped by gripping tool finger means to advance the valve in the urethra.

10. In apparatus for controlling body fluid flow in a body internal duct, the combination comprising:
-
a) an endwise elongated magnetically responsive valve of a size to be inserted in series with said internal duct, to be responsive to a separate valve actuating magnet, b) the valve having a body structure and a rotary valving element rotatable relative to said structure, the said element having magnetic pole means providing a magnetic field, c) the valving element being rotatable between body fluid flow passing and flow blocking positions, by controlling the position outside the body of said actuating magnet, thereby causing the magnetic field of the actuating magnet to interact with the magnetic field of the rotary valving element pole means, d) there being grip means on the valve at one end thereof, the valve having a cylindrical outer surface, the grip means located within a cylinder defined by said surface, to be gripped by gripping tool finger means to advance the valve in the urethra, in said duct. - View Dependent Claims (11)
