An apparatus includes a bodily implant configured to be implanted into a body of a patient. The bodily implant includes an inflatable member, a sensor, and a controller. The inflatable member is configured to be disposed within a portion of the body of the patient and place pressure on a portion of a body of th patient. The sensor is operatively coupled to the inflatable member and configured to detect a fluidic pressure within the inflatable member. The controller is configured to receive pressure data from the sensor during a transition between a deflated configuration and an inflated configuration of the inflatable member and detect, based on the received pressure data, atrophy of the portion of the body of the patient.

According to an aspect, an inflatable penile prosthesis includes a fluid reservoir configured to hold fluid, an inflatable member, and an electronic pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member. The electronic pump assembly includes a pump, an active valve, and a controller configured to receive an external signal to activate an inflation cycle and control at least one of the pump or the active valve to transfer the fluid to the inflatable member. The controller includes a printed circuit board assembly. The printed circuit board assembly includes a microprocessor or a state machine.

According to an aspect, an electronic pump assembly includes a pump configured to move fluid between from or to a fluid reservoir of a device. The pump includes a passive valve. The electronic pump assembly includes a controller configured to actuate the pump and a flow modifier configured to restrict a flow of fluid entering or within the pump.

An implantable inflation device includes a fluid reservoir defining a cavity, an inflatable member; an inflation fluid, a pump assembly, and a circuit for measuring electrical resistance. The pump assembly is configured to transfer the inflation fluid from the fluid reservoir to the inflatable member. The circuit is configured to measure an electrical resistance between the inflation fluid within the implantable inflation device and a body of a patient in which the implantable inflation device is implanted.

An implantable fluid operated device may include a fluid reservoir configured to hold fluid, an inflatable member, and an electronic fluid control system to transfer fluid between the fluid reservoir and the inflatable member. The fluid control system includes at least one pump or at least one valve including a piezoelectric actuator. The piezoelectric actuator can include a piezoelectric element that deforms in response to a voltage applied by an electronic control system of the fluid control system, and a diaphragm that deforms in response to deformation of the piezoelectric element. An isolation layer may be coupled to the piezoelectric element to isolate the active piezoelectric element from non-active portions of the piezoelectric actuator.

An artificial bladder is provided, including: a main body which includes an inlet port, an outlet port, an inner wall that forms a first reservoir portion configured to store urine between the inlet port and the outlet port and that is expandable and contractible. An outer wall forms a second reservoir portion configured to surround at least a partial region of the inner wall. A sensor is attached to the inner wall, has a surface having a wrinkled structure, and is provided so that, when the volume of the first reservoir portion increases, the wrinkled structure stretches out and resistance of the sensor changes. A control unit is provided to discharge the urine in the first reservoir portion through the outlet port according to a result detected by the sensor.
