An orthopaedic tibial prosthesis includes a tibial baseplate with features designed for use with small-stature knee-replacement patients. The tibial prosthesis may include a shortened tibial keel, tibial keel fins which define a large angle with respect to a longitudinal axis of the keel, and/or tibial keel fins which extend along less than the entire longitudinal extent of the keel.

An implantable, autonomously growing medical device is disclosed. The device may have an outer, braided outer element that holds an inner core. Degradation and/or softening of the inner core permits the outer element to elongate, allowing the device to grow with surrounding tissue. The growth profile of the medical device can be controlled by altering the shape/material/cure conditions of the inner core, as well as the geometry of the out element.

The present disclosure is directed to an expandable medical implant for the repair of cranium defects in adolescent patients. The implants of the present disclosure can include a plurality of interconnected links that are movable with respect to each other as the underlying cranium grows and expands.

Disclosed are a method for limiting diffusion of wear debris of an in vivo implant and an in vivo implant apparatus with a function of limiting wear debris. An elastomer seal is arranged at a wearing part between implant components that can move relatively and generate wear, such that an outlet for wear debris of the implant is always sealed within a sealing area formed by the seal and the implant components, thereby preventing the wear debris from diffusing outwards. The elastomer seal includes at least one flexible buffer part for reducing or completely offsetting relative motion between the implant components, thereby further reducing wear of a sealing part of the elastomer seal due to the relative motion between the parts. The seal is tightly attached to in vivo implant components, and the in vivo implant is smaller than a force for driving the components to generate relative motion.

An expandable valved conduit for pediatric right ventricular outflow tract (RVOT) reconstruction is disclosed. The valved conduit may provide long-term patency and resistance to thrombosis and stenosis. The valved conduit may enlarge radially and/or longitudinally to accommodate the growing anatomy of the patient. Further, a method is disclosed for the manufacture of the valved conduit based in part on a plastically deformable biocompatible polymer and a computer-optimized valve design developed for such an expandable valved conduit.

The invention herein described is an endoprosthesis intended to replace a resected portion of bone and joint. The invention can be non-invasively, manually operated to lengthen a patient's limb both intraoperatively and postoperatively. It includes bone anchoring components for anchoring to a first and second long bone, a joint to replace the function of an orthopedic joint, and a purely mechanical lengthening mechanism which can be located and operated manually by an operator by pressing on skin of a patient without requiring a surgical incision. An alternative embodiment of the invention describes a similar extendable endoprosthesis which is unlocked by an operator by pressing on skin of a patient and the limb is subsequently pulled or pushed by the operator to change its length. The invention does not need or include any magnets, electric motors, electric current, application of heat or a fluid displacement (hydraulic) system.
