An implant removal tool (1) used to remove a femoral implant (17) from a femur bone (18) by providing a substantially U-shaped body (2) having a substantially rectangular-shaped opening (9) located thereon that allows the substantially U-shaped body to be placed over a neck (21) of a femoral implant so a sharpened front edge (5) of the substantially U-shaped body makes direct contact with an inner surface of the stein of the femoral implant. The U-shaped body may have front side edges (26, 27) that extend beyond a front edge (5) to allow the front side edges to cut anterior and posterior surface of the implant.

A probe unit includes, a probe configured to treat a bone by ultrasonic vibration, a hollow sheath which surrounds the probe and which has a first portion at a small distance from a central axis, and a second portion at a greater distance from the central axis than the first portion, and a knob configured to rotate the sheath relative to the probe between a first position for insertion between the bone and a living tissue facing the bone so that the first portion is located between the bone and the living tissue and a second position for insertion between the bone and the living tissue so that the second portion is located between the bone and the living tissue.

A bone anchor delivery system device (10) has a retractable punch driver assembly and a locking mechanism (32). The punch driver assembly has a retractable punch shaft (30) and a guide (20) for receiving the retractable punch shaft (30). The guide (20) is rotatable relative to the punch shaft (30) and the shaft has an extended length with bone penetrating tip (35) at a first end (33). The locking mechanism (32) for locking the retractable punch shaft (30) from linear movement and rotational movement relative to the guide (20) is positioned at an opposite second end. The retractable punch shaft (30) has a reduced diameter end (33) extending from the tip (35) toward a shoulder stop for receiving a releasable punch (12). The releasable punch (12) has a hollow opening for receiving the reduced diameter end (33) of the punch shaft (30). The punch (12) is profiled to pierce and form a bone anchor hole.

The invention is directed to producing a shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. The invention relates to a process for repairing a cartilage defect and implantation of a cartilage graft into a human or animal by crafting the cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation. The devitalized cartilage graft is also optionally stored between the removing cellular debris and the recellularizing steps.

Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface bears at least one anchoring element adapted for an oblique implantation trajectory. The articular surface may include a larger radius of curvature in the superior-inferior direction than in the anterior-posterior direction. An inferior chamfer may be present on the articular surface. Instruments and implantation methods are also disclosed.

A method and system are provided for preparing an interspinous space to receive an implantable device. The system may comprise a cutting tool guide having a guiding surface for directing a cutting tool therethrough and a holder for positioning the cutting tool guide relative to the interspinous space. The holder may be configured to adjustably attach to at least one of a pair of spinous processes defining the interspinous space.

A surgical method and tool for expanding an initial osteotomy (42) to receive a bone implant (44). An osteotome (22) having a tapered working end (28) is inserted into the initial osteotomy (42). The initial osteotomy (42) is enlarged by simultaneously rotating and pushing the working end (28) of the tapered osteotome (22) into the osteotomy (42). When rotated in one direction the burnishing edges (40) concentrate the pushing and rotational force in outward normal and tangential component forces against the interior surface of the osteotomy (42) to incrementally expand the osteotomy (42) with little to no removal of bone material (46). When rotated in the opposite direction the burnishing edges cut the interior surface of the osteotomy. Progressively larger tapered osteotomes (22) are used until an osteotomy (42) of predetermined size is achieved.

A spinal joint distraction system is disclosed and may include a driver assembly with a tubular shaft, a pair of implant holder arms, an implant distractor, an internal actuator, and a distractor knob, the system also including a delivery device with a tubular shaft, a receiving assembly, and a pair of forks, where the delivery device is adapted for slidable insertion of the driver assembly, the system also including an implant, a chisel, and an injector. Several embodiments of an implant are disclosed as well a method of placing an implant.

A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.

An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.
