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.

A device for controlling the functioning of a cardiac prosthesis, the device for controlling includes a control path, the control path having a control system designed and arranged to monitor and regulate the electrical supply of a cardiac prosthesis; a first insulating system designed and arranged to electrically insulate the cardiac prosthesis from the electrical supply; and a controller designed and arranged to monitor and regulate the electrical supply.

The present disclosure provides alert implants that comprise a medical device and an implantable reporting processor (IRP), where one example of such a medical device includes a component for a total knee arthroplasty (TKA) such as a tibial extension, a femoral component for hip replacements, a breast implant, a distal rod for arm or leg breakage repair, a scoliosis rod, a dynamic hip screw, a spinal interbody spacer, and tooling and methods that may be used to form the alert implant, and uses of such alert implants in the health maintenance of patients who receive the implant.

Systems, methods, and apparatuses for relieving upper airway obstructive breathing in a patient are disclosed. In some implementations, the apparatus comprises first and second pivot devices anchored to a mastoid bone and a mandible bone, respectively; an implant positioned between the first and second pivot device, the implant comprising a first end coupled to the first pivot device and a second end coupled to the second pivot device; an inactive position, the inactive position enabling a posterior displacement of the second end relative to the first end; an active position, the active position preventing posterior displacement of the second end relative to the first end, and anteriorly positioning the second end relative to the first end; and an activation mechanism enabling transition between the inactive position and the active position, and vice versa.

Various systems, devices, components and methods are disclosed for controllably and selectively occluding, restricting, and/or diverting flow within a patient's vasculature. The flow restriction systems can include an implant having a flow restrictor and an implantable controller having an actuator for actuating the flow restrictor. The flow restriction systems can also include an external device for controlling operation of the implant via the implantable controller.

An implantable joint prosthesis simulating an elbow joint, an ankle joint, a shoulder joint or a hip joint, the implantable prosthesis having one or more integrated biasing system(s) configured to bias the prosthetic joint to one or more preferred orientations or alignments.

The invention herein described is an endoprosthesis intended to replace a resected portion of bone and joint. The invention can be non-invasively, manually operated to lengthen a patient's limb both intraoperatively and postoperatively. It includes bone anchoring components for anchoring to a first and second long bone, a joint to replace the function of an orthopedic joint, and a purely mechanical lengthening mechanism which can be located and operated manually by an operator by pressing on skin of a patient without requiring a surgical incision. An alternative embodiment of the invention describes a similar extendable endoprosthesis which is unlocked by an operator by pressing on skin of a patient and the limb is subsequently pulled or pushed by the operator to change its length. The invention does not need or include any magnets, electric motors, electric current, application of heat or a fluid displacement (hydraulic) system.

A muscle-driven endoprosthesis system may include a bone extension, an intramedullary stem extending form a first end of the bone extension, a joint at a second end of the bone extension, a moveable portion coupled to the hinge, and synthetic tendons coupled to the moveable portion. The bone extension, intramedullary stem, hinge, and movable portion are sized and shaped to fit within a skin of a patient.

Prosthetic devices allow for full articulation of the joint, while absorbing impact of the components during normal use that will reduce wear on the device components and prolong life. The device may include a bone implantable component and a bearing component having an articulation surface that is sized and shaped to substantially mate with at least a portion of the bone implantable component and a damping mechanism that includes a contact member disposed at least primarily inside a cavity; a biasing member biasing the contact member toward an upper aperture of the cavity and means for capturing the contact member within the cavity.
