A system for attachment of a device to a bone is provided. The system includes an internal axial rod with a proximal and distal end that is configured to be inserted and secured into a bone cavity’s distal end. The system can also include an internal-external transfer rod with a proximal and distal end mounted into the distal end of the axial rod and a central channel extending through the transfer rod from the proximal end to the distal end and a plurality of attachment rings for attaching at least one tissue or muscle group to the transfer rod. The system also includes a bio-compatible and bio-occlusive artificial membranes (BIOCAMS) lamina, wherein the lamina includes either a polyetheretherketone (PEEK) mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissue, allogenic tissue, a collagen/hyaluronic acid-based tissue, or connective tissue biosynthetic substrate material suitable as webbing.

A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of creating a hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.

An implantable medical device for implantation in a hip joint of a human patient is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

A method of treating a hip joint of a human is provided. The method comprises a step of dissecting an area of the pelvic bone, comprising at least one of the following: dissecting an area between peritoneum and the pelvic bone, dissecting an area between the pelvic bone and the surrounding tissue, dissecting an area of the pelvic region, and dissecting an area of the inguinal region, or, the method comprises at least two of the following steps: dissecting an area of the abdominal cavity, penetrating the hip joint capsule, dissecting an area between peritoneum and the pelvic bone, dissecting an area of the pelvic bone which comprises: dissecting an area between the pelvic bone and the surrounding tissue, or dissecting an area of the pelvic region, or dissecting an area of the inguinal region, and removing or penetrating the tissue surrounding the pelvic bone in the area opposite to acetabulum.

A method of treating a hip joint of a human patient by providing said the medical device is provided. The hip joint comprising a caput femur and an acetabulum, the method comprises the steps of: cutting the skin of the patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through said pelvic bone and into the hip joint of the patient, and providing said medical device to the hip joint, through said hole in the pelvic bone of the patient.

An implantable medical device, for implantation in a mammal knee joint, comprising an artificial contacting surface adapted to replace at least one contacting surface of the knee joint and to be lubricated when implanted in said joint. The medical device further comprises a reservoir comprising a movable wall portion defining the volume of the reservoir, at least one inlet adapted to receive a lubricating fluid from the reservoir, at least one channel at least partly integrated in said artificial contacting surface, wherein the channel is fluidly connected with said at least one inlet for distributing said lubricating fluid to the surface of said artificial contacting surface. The medical device further comprises an operation device adapted to non-invasively transport said lubricating fluid from said reservoir to said artificial contacting surface, and an implantable injection port for refilling said reservoir, wherein the movable wall portion is moved when the reservoir is refilled, such that the volume of the reservoir is increased.
