Implantable sphincter system utilizing lifting means
First Claim
1. An implantable sphincter system for reversibly occluding and opening a tubular passageway of a human body, which comprises,lifting and lowering means comprising a spring operated cord adapted to be in integral contact with or disposed about the tubular passageway, which when raised to a predesignated position within the human body will occlude the passageway and when lowered below said position will open the passageway;
- positioning means integral with said lifting and lowering means to position said lifting and lowering means, as desired;
actuating means operably connected to said lifting and lowering means;
pump means capable of being volitionally operated, said means being in fluid communication with, and capable of supplying pressurized fluid to said actuating means, wherein when said pressurized fluid is applied to said actuating means, said lifting and lowering means are lowered to the position wherein the body passageway assumes an open mode; and
,time delay means disposed between said pump means and said actuating means to sequentially enable a reverse pressurized liquid flow to cause the lifting and lowering means to return automatically to the predetermined raised position, and the passageway to an occluded mode.

Abstract
An implantable artificial sphincter system for reversibly occluding a body passageway, preferably the urethra, enables the body passageway to be opened and closed in sequence due to the action of a lifting and lowering device which is adapted to be in integral contact with or disposed about the body passageway. An actuating device is operably connected to the lifting and lowering device, and a pump capable of being volitionally operated is in fluid communication with the actuating device to provide a pressurized flow of fluid into the actuating device.

5. An implantable sphincter system for reversibly occluding and opening a urethra, which comprises,
lifting and lowering means adapted to be attached to or about the urethra, said means comprising a cord, the lower portion of which depends downward from an actuator, wherein, when said cord is in an elevated predetermined position within the human body the urethra will be occluded, and when lowered below said position the urethra will be opened; -
said actuator including a spring about which is defined an upper portion of said cord; pump means capable of being volitionally operated from outside the body, said pump means being in fluid communication with, and capable of supplying fluid under pressure to said actuator whereby when said pressurized fluid is applied to said actuator said spring is compressed thereby lowering the depending portion of the cord to the position wherein the urethra assumes an open, voiding mode; and time delay means between said pump means and actuator to sequentially enable a reverse pressurized liquid flow to cause the cord to return automatically to the predetermined elevated position, and the urethra to the occluded mode. - View Dependent Claims (6, 7, 8, 9, 10, 11)
