Abstract
A urinary incontinence treatment apparatus comprises an adjustable restriction device (234) implanted in a patient, who suffers from urinary incontinence. The restriction device engages the urethra (244) of the patient to restrict, i.e. to close the urine passageway. An implanted adjustment device is adapted to adjust the restriction device such that the urethra is temporarily released, in order to open the urine passageway when the patient wants to urinate. An implanted powered hydraulic operation device (246) operates the adjustment device.
Claims157
A urinary incontinence treatment apparatus, comprising an adjustable restriction device (2) adapted to engage the urethra or urine bladder of a patient, who suffers from urinary incontinence, to form a restricted urine passageway in the urethra or urine bladder, an implantable adjustment device (5) for adjusting the restriction device (2) to restrict the urethra or urine bladder to close the urine passageway, or release the urethra or urine bladder to open the urine passageway, when the restriction device is implanted in the patient, and an implantable electrically powered operation device (6,8;10;12;10,14;76-86) for operating the adjustment device, characterised by a reservoir (4;10;16) implantable in the patient and containing hydraulic fluid, wherein the operation device (6,8;10;12;10,14;76-86) is adapted to operate the adjustment device (5) by using the hydraulic fluid of the reservoir.
A urinary incontinence treatment apparatus, comprising an adjustable restriction device (2) adapted to engage the urethra or urine bladder of a patient, who suffers from urinary incontinence, to form a restricted urine passageway in the urethra or urine bladder, an implantable adjustment device (5) for adjusting the restriction device (2) to restrict the urethra or urine bladder to close the urine passageway, or release the urethra or urine bladder to open the urine passageway, when the restriction device is implanted in the patient, and an implantable operation device (6,8;10;12;10,14;76-86) for operating the adjustment device, characterised in that the operation device comprises a servo means operatively connected to the adjustment device.
An apparatus according to any of the preceding claims, further comprising a wireless remote control for non-invasively controlling the hydraulic operation device.
An apparatus according to any one of the preceding claims, further comprising at least one implantable sensor for sensing at least one physical parameter of the patient.
An apparatus according to any of the preceding claims, further comprising a switch implantable in the patient for directly or indirectly switching the operation of the restriction device.
An apparatus according to any of the preceding claims, wherein the restriction device is embedded in a soft or gel-like material.
An apparatus according to any of the preceding claims, wherein the adjustment device is adapted to adjust the restriction device such that the restriction device provides a predetermined contraction of the urine passageway that is satisfactory for the patient.
