Implantable devices, such as artificial organs, increasingly incorporate hardware, software, firmware, and/or wireless communication capabilities. For example, such implantable devices can utilize wireless technology to allow for efficient configuration, maintenance, and operational analysis. As these implantable devices become more connected, electronic security will become more important. This disclosure relates to implantable devices that may utilize a secure boot process and secure communication, both between artificial devices in the human body and between these devices and the external world. This disclosure provides secure communication approaches for maintaining the digital privacy and integrity of artificial devices, for protecting the individual from malicious hacking of data, and for controlling of such implantable devices.

A prosthetic disc can take the form of a sensing artificial disc that includes a resilient core and at least one sensor configured to sense one or more conditions within and/or experienced by the disc. The sensing artificial disc can serve as a replacement to a failed or injured disc between two vertebrae of a spine. The sensing artificial disc can include at least one element configured to change a condition or property of the resilient core in response to a condition sensed by the at least one sensor. A prosthetic disc can include therapeutic system configured to deliver medication to the body, which can include a reservoir of medication.

Embodiments of a system and method for assessing hip arthroplasty component movement are generally described herein. A method may include receiving data from a sensor embedded in a femoral head component, the femoral head component configured to fit in an acetabular component, determining information about a magnetic field from the data, and outputting an indication of an orientation, coverage, or a force of the femoral head component relative to the acetabular component.

A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating fluid and a fluid connection for introducing the lubricating fluid into the joint when the device is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.

A prosthetic implant includes a cavity that opens at an outer face of the prosthetic implant, the cavity forming a housing for receiving: a printed circuit including a radio tag; and a cover which closes the cavity at least partially when positioned on the implant in a so-called closed position, the radio tag and printed circuit being removably housed in the cavity.

A system and method for powering a medical device that includes a fixture configured for periodic patient proximity; external electrical coupling device integrated into the fixture wherein the external electrical coupling device comprises at least one external energy coupler and is configured to detect presence of an electrical medical device implant in a transmission zone of the external electrical coupling device; an electrical medical device implant, wherein the electrical medical device implant comprises at least one implant energy coupler; and wherein the external electrical coupling device is configured to couple to the implantable medical device through a wireless energy transmission between the external energy coupler and the implant energy coupler when presence of the implantable medical device is within a transmission zone.

A device for treating a vascular aneurysm of a human or mammal patient, comprising an implantable member adapted to hold fluid, the implantable member being adapted to be placed against an outside of a blood vessel having the aneurysm, exercise a pressure on the aneurysm to prevent or reduce an expansion of the aneurysm, follow an outer contour of the aneurysm, and provide a pressure that is equal or less than the diastolic blood pressure of the human or mammal patient.

A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

A method of transferring electrical power to a medical device implanted in a patient includes supporting a prosthetic rib segment via a rib of the patient. A percutaneous electrical connector is supported via the prosthetic rib segment so as to expose a connection port of the electrical connector via a skin aperture through a skin portion of the patient. Electrical power is transferred to the medical device via an external power cable connected to the connection port and an implanted power cable connected with the percutaneous electrical connector.
