A medical device for delivering an action to an area of a hip joint or its surroundings, inside a human body, is provided. The hip joint of a patient comprises a collum femur and a ball shaped caput femur, being the proximal parts of the femoral bone, and an acetabulum, being a bowl shaped part of the pelvic bone. The medical device comprising; an elongated member, having a length axis along its elongated distribution, comprising a first portion, adapted to enter the body of the patient, and a mechanical element, adapted to be used during an operation in the hip joint or its surroundings, inside the body. The first portion of the elongated member comprises a holding member adapted to hold the mechanical element inside the body of the patient, wherein the first portion of the elongated member have a first portion cross-section area substantially perpendicular to the length axis of the elongated member. The first portion is adapted to pass through a hole, in a bone of the patient, the hole having a hole cross-section area. The first portion cross-section area, is adapted to be smaller than said hole cross-section area. The mechanical element have a functional status, ready to deliver said action inside said body, when held by the holding member inside the body of the patient. The mechanical element is adapted to have a mechanical element cross-sectional area substantially perpendicular to the length axis of the elongated member, substantially larger than the first portion cross-sectional area and adapted to be unable to pass through the hole, when the mechanical element is in the functional status.

A method for fixating an artificial convex caput femur surface to the pelvic bone of a patient, the method comprising the steps of: exposing the acetabulum surface, creating a hole or recess in the pelvic bone from the acetabulum side of the pelvic bone, providing the artificial convex caput femur, comprising an elongated member to the hip joint, inserting said elongated member in said hole, and performing an action on the acetabulum side of the pelvic bone such that the elongated member is structurally changed on the abdominal side of the pelvic bone or inside the pelvic bone.

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 cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area using said pelvic drill, said 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.

A percutaneous collar is made up of a central rigid ring and a flexible mesh inside a microporous silicone disc. The volume of the disc has a three-dimensional network of interconnected micropores forming microchannels connecting both external faces of the disc through the external micropores to the internal flexible mesh wherein the flexible mesh is formed by crossed longitudinal and radial elements or plates which form a plurality of holes.

A cage device for harvesting bone graft material for use in bone fusion surgery, e.g., a spinal fusion. The device has a chamber configured to contain a slurry of morselized bone and blood that effuses from adjacent bones when the device is placed in a space between the bones, and a bone cutter assembly is inserted into the chamber and operated. In one embodiment, the cutter assembly includes an elongated cannula having a bend at a distal end, and a wire arranged to slide inside the cannula so that a cutting tip of the wire can be set to project a desired distance from the distal end. When the cannula is driven to rotate about its long axis, the wire cutting tip strikes and cuts grooves in the facing surfaces of the bones to produce the mentioned slurry which remains inside the chamber to promote a solid and healthy fusion.

Systems, devices and methods for providing orthopedic augments having recessed pockets that receive a fixation material. The orthopedic augments include an outer surface that interfaces with a patient's tissue or bone, an inner surface that interfaces with an implant and having a recessed pocket configured to receive a fixation material, a rim around at least a portion of the recessed pocket, and a port in the rim, wherein the recessed pocket extends along the inner surface in at least a lateral direction from the port.

An implant to fill a hole in tissue, such as bone tissue, comprising a first portion that is insertable through the hole when in a first compressed position, wherein the first portion cannot pass through the hole when in a first deployed position; and a second portion that cannot pass through the hole when in the second deployed position. The first and second portions of the implant can be deployed independently. Therefore, in operation, it is possible to insert the first portion of the implant through the hole when in the first compressed position, deploying the first portion to transition it to the first deployed position while the second portion remains in the second compressed position, and then deploying the second portion to transition it to the second deployed position. The devices and methods may be used, for example, in transsphenoidal or other orthopedic surgeries involving bone tissue.

An implantable medical device for implantation in a hip joint 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.

The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.

The present disclosure includes, in one embodiment, a talar component of an ankle joint prosthesis for engagement with a talus bone having a medial side wall and a lateral side wall, opposite the medial side wall, each side wall terminating at a distal edge, and the distal edges adapted to drive into the talus bone. When implanted, the side walls may form a seal between the talus bone and the component to prevent fluid from flowing under the component.
