An operable implant adapted to be implanted in the body of a patient. The operable implant comprising an operation device and a body engaging portion, the operation device comprises an electrical motor comprising a static part comprising a plurality of coils and a movable part comprising a plurality of magnets, such that sequential energizing of said coils magnetically propels the magnets and thus propels the movable part. The operation device further comprises an enclosure adapted to hermetically enclose the coils of the static part, such that a seal is created between the static part and the propelled moving part with the included magnets, such that the coils of the static part are sealed from the bodily fluids, when implanted.

An apparatus for controlling the flow of urine in a urethra of a patient, comprising an implantable adjustable constriction device for constricting the urethra, a control device for controlling the constriction device, an operation device for operating the constriction device to change the constriction of the urethra, and an energy source for supplying energy for the operation device. The control device comprises a temperature sensor configured to sense a temperature of the apparatus or a temperature of the patient.

An apparatus for controlling the flow of urine in a urethra of a patient is disclosed. The apparatus comprises an implantable adjustable constriction device for constricting the urethra to influence the flow in the urinary tract, an operation device for operating the constriction device, and a control device for controlling the operation device to constrict the urethra and to release the urethra. Further, the apparatus comprises an energy source for supplying energy to the operation device, wherein the control device is configured to determine the current state of the energy source, and wherein the control unit is connected to an internal signal transmitter configured to transmit information related to the current state of the energy source.

A system and method for collecting operation data associated with a medical apparatus including an internal device implanted in a subject and an external device that is magnetically-coupled to and drives the internal device. The medical apparatus may be monitored to obtain raw data associated with the operation of the medical apparatus and one or more calculations may be performed on the raw data, wherein the raw data and/or calculated values may be associated with voiding frequency and voiding volume of the subject. A report may be generated from the raw data and/or calculated values. In addition, one or more signals may be sent to the external device and/or a docking station, or communicated by other means, to indicate to the subject that the operation of the medical apparatus should be altered.

A method for treating a female urinary incontinent patient is provided. The method comprises the steps of accessing a urethra or a neck of a urinary bladder through an opening in the vaginal wall of the patient; implanting a hydraulic or mechanical powered restriction device in connection with the urethra or the neck of the urinary bladder, wherein the powered restriction device is configured to decrease a cross-sectional area of the urethra or the neck of urinary bladder in order to stop or decrease the flow of urine through the urethra or the neck of the urinary bladder, implanting an energy source, using a vaginal approach or using a vaginal approach in combination with a skin incision; and connecting the powered restriction device directly or indirectly to the energy source, to power the powered restriction device.

A system for communicating with a medical implant in a body of a user is provided. The system comprises a command generator and a memory, wherein the command generator is configured to receive a voice command from the user and to reduce noise, generated by the body, from the received voice command to generate a noise-reduced voice command. The command generator is further configured to compare the noise-reduced voice command with previously stored voice commands and to transmit a command signal to the implant in case the noise-reduced voice command corresponds to any of the previously received commands stored in the memory.

An apparatus for controlling a flow of urine in a urethra of a patient is disclosed. The apparatus comprises an implantable constriction device for constricting the urethra to influence the flow in the urinary tract, comprising a plurality of clamping elements configured to be arranged in a common plane intersecting the urethra and to be radially movable towards and away from a central axis of the urethra. The apparatus further comprises an operation device configured to operate the clamping elements, and an implantable motor configured to operate the operation device. The operation device is configured to operate the movement of the clamping elements such that the movement is predominantly inelastic, and such that a clamping force, acting on the urethra, is distributed between the clamping elements.

There is provided a method for controlling a flow of intestinal contents in the intestinal passageway of a patient's intestines. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the intestinal tissue wall) at least one portion of the intestinal tissue wall to influence the flow in the intestinal passageway, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the intestinal passageway. The method can be used for restricting or stopping the flow in the intestinal passageway, or for actively moving the fluid in the intestinal passageway, with a low risk of injuring the intestines.

An apparatus for controlling the flow of urine in a urethra of a patient is provided, comprising an implantable adjustable constriction device for constricting the urethra to influence the flow in the urinary tract, a control device for controlling the constriction device, wherein the control device is configured to control the constriction device to constrict the urethra or to release a constriction of the urethra, and an operation device for operating the constriction device. The apparatus further comprises an energy source for supplying energy for the operation device, wherein the control device comprises a temperature sensor configured to sense a temperature of the apparatus or a temperature of the patient.

According to some embodiments, systems and methods are provided for non-invasively detecting the force generated by a non-invasively adjustable implantable medical device and/or a change in dimension of a non-invasively adjustable implantable medical device. Some of the systems include a non-invasively adjustable implant, which includes a driven magnet, and an external adjustment device, which includes one or more driving magnets and one or more Hall effect sensors. The Hall effect sensors of the external adjustment device are configured to detect changes in the magnetic field between the driven magnet of the non-invasively adjustable implant and the driving magnet(s) of the external adjustment device. Changes in the magnetic fields may be used to calculate the force generated by and/or a change in dimension of the non-invasively adjustable implantable medical device.
