A solid lubricant for use in a medical device for lubrication of a synovial joint, wherein said lubricant comprises at least one of: a high-molecular weight hyaluronic acid; a crosslinked high-molecular weight hyaluronic acid; and a hyaluronic acid of at least two different high-molecular weights being crosslinked to form a semisolid gel.

A surgical instrument for operating hip joint osteoarthritis in a human patient is provided. The hip joint comprises an acetabulum, being a part of the pelvic bone, and a caput femur, being the proximal part of the femoral bone. The surgical instrument is adapted to assist in the operating of the hip joint osteoarthritis from the abdominal side of the pelvic bone of said human patient.

The present invention relates to a method for implanting a device for treating an aneurysm of a patient. The method involves cutting the skin of said patient, dissecting an area of a blood vessel having the aneurysm, placing an implantable member in connection with the outside of the blood vessel having the aneurysm to exercise a pressure on the outside of the blood vessel having the aneurysm and placing a measuring device or sensor in connection in the body of the patient, wherein the measuring device or sensor is configured to measuring or sensing an expansion of the aneurysm.

One aspect of the disclosure relates to an extramedullary distraction and compression system. The extramedullary distraction system includes: a housing configured to be attached to a bone at a first location, the housing having a magnet and a lead screw positioned therein, wherein the lead screw is coupled to the magnet such that rotation of the magnet causes rotation of the lead screw, at least one retainer clip disposed around the lead screw; a rod configured to be attached to the bone at a second location and configured to interact with the lead screw such that, upon rotation of the lead screw, the rod distracts or contracts relative to the housing.

A device for treating an aneurysm of a human or mammal patient, wherein the aneurysm may self-expand. The device comprising an implantable member adapted to be placed in around an outside of a blood vessel having the aneurysm to enable the implantable member to exercise a pressure on the outside of the blood vessel having the aneurysm. The device further comprising a measuring device or sensor for measuring or sensing an expansion of the aneurysm and a monitoring system adapted to monitor the expansion of the aneurysm based on a signal received from the measuring device or sensor.

A surgical and a laparoscopic/arthroscopic method for operating hip osteoarthritis using an instrument that is adapted to create a through-going hole placed in the acetabulum area from the abdominal side of the pelvic bone of the human patient. The instrument comprises: a driving member, a bone contacting organ in connection with said driving member, an operating device adapted to operate said driving member. The bone contacting organ is adapted to create a hole in the acetabulum area starting from the abdominal side of the pelvic bone through repetitive or continuous movement.

A fluid exchange electrode is defined by a multi-layered electrode body including a conductive electrode material layer disposed in an electrode body and an ionically conducting assembly that interfaces with the skin of a patient. A source of electrolytic fluid is coupled to an inflow tube and configured to permit a volume of electrolytic fluid to be circulated through the electrode body to increase treatment duration and overall electrode life in which the temperature of the cycled electrolytic fluid can be regulated. The cycled electrolytic fluid can be disposed of or preferably recirculated via a return or outflow tube to the source of electrolytic fluid. The herein described fluid exchange electrode can be used as part of a treatment system that applies a DC voltage in order to remove bacteria from a metal surgical implant.

Embodiments provide a method for determining an alternating magnetic field (AMF) transmitter design that produces a magnetic field that achieves a more uniform surface current or heating of an implant. Embodiments may utilize the method to be applicable to different geometries of implants and AMF transmitters. Embodiments produce a non-uniform magnetic field that in turn produces a more uniform current density/distribution on the implant surface. This leads to uniform heating and consistent biofilm reduction, while minimizing damage to adjacent tissues. Also, the differences in electrical properties such as conductivity, permittivity, and permeability of the implant components can be factored into the design process to achieve a uniform current density/distribution across components. An ultimate benefit derived from embodiments described herein is consistent biofilm reduction, inactivation, eradication, destruction, and/or removal and improved safety arising from heat conduction into surrounding tissues.

Provided herein is an adjustable implant configured to non-invasively guide bone growth in a patient. The adjustable implant includes a first portion configured to couple to a first bone segment and a second portion at least partially disposed within the first portion and configured to couple to a second bone segment. The adjustable implant includes a drive assembly configured to be transcutaneously actuated, and to drive rotation of a gear assembly configured to rotate about a first axis, and drive axial translation of the second portion along a second axis. Non-invasive actuation of the drive assembly therefore causes the adjustable implant to distract or retract along the second axis.

One aspect of the disclosure relates to an extramedullary distraction and compression system. The extramedullary distraction system includes: a housing configured to be attached to a bone at a first location, the housing having a magnet and a lead screw positioned therein, wherein the lead screw is coupled to the magnet such that rotation of the magnet causes rotation of the lead screw, at least one retainer clip disposed around the lead screw; a rod configured to be attached to the bone at a second location and configured to interact with the lead screw such that, upon rotation of the lead screw, the rod distracts or contracts relative to the housing.
