Methods and devices for correcting wear pattern defects in joints. The methods and devices described herein allow for the restoration of correcting abnormal biomechanical loading conditions in a joint brought on by wear pattern defects, and also can, in embodiments, permit correction of proper kinematic movement.

An orthopedic prosthesis includes a head which internally accommodates the major motion of a patient, e.g., during walking, thereby reducing wear against a cup or liner. A neck may be utilized which rotates within the distal member about an axis aligned with the major motion of the patient. The orthopedic prosthesis may also include a sacrificial anode, a seal made of natural fibers, and utilize lubricant made of honey.

The invention relates to a screw, which is used specifically in the field of oral dental surgery. The screw consists of a bioresorbable material and comprises a drive that can be broken off by means of a predetermined breaking point and/or has a thickened shaft below the contact surface of a cap of the head of the screw.

An implant having a unitary body includes an intramedullary portion and an extramedullary portion. The intramedullary portion is sized and structured to be received within an intramedullary canal of a first bone and defines a longitudinal axis. The extramedullary portion includes a surface defining an axis that is disposed at an angle with respect to the longitudinal axis. An aperture defined along the extramedullary portion is sized and configured to receive a fastener therein for coupling the extramedullary portion of the implant to a second bone.

A medical valve implant includes an implant structure fastened to a base body. The base body has cells that extend in a circumferential direction of a valve implant. An end section bulges in a curved shape outwardly in a radial direction of the base body. The end section has a larger diameter than an axially adjacent collar portion of the base body. A collar includes a first cell structure provided to form, in an intended end state, an intended inner cross-section of the base body that is matched to an intended outer cross section of the implant structure. A holding device extends axially from and beyond the cells. The holding device includes a leg directly connected to a terminal end of one of the cells and a head at an opposite end of the leg. One or both of the leg and the head is canted radially inward toward a geometric center of the base body.

Provided are biodegradable orthopedic implants, corrosion-resistant coating for orthopedic implants, and methods of making. The biodegradable orthopedic implant can include a Mg alloy having a coating including a first layer, a second layer, and a third layer. The first layer can be an oxide layer coated on an external surface of a magnesium alloy implant. The second layer can include lawsone embedded in PCL, and the third layer can include PCL. To manufacture the coated orthopedic implant, the implant can be immersed in an alkaline solution to form an oxide-coated implant and implant can then be coated with a PCL lawsone solution. An additional polymer protective layer can be added.

A medical valve implant having a medical heart valve fastened to a base body, the base body having a circumferential arrangement of cells with a proximal end and a distal end to provide inflow and outflow sections when implanted, where some of the cells at the distal end are connected to holding devices that cant inward. Within the cells can be smaller cells having two halves configured for outward movement relative to the larger surrounding cell.

A medical valve implant comprising: an implant structure configured as a medical valve; and a base body that includes a collar extending in a circumferential direction around the implant structure, wherein the collar includes a first cell structure composed of a plurality of cells forming an inner cross section of the base body that is matched to an outer cross section of the implant structure, characterized in that the collar includes a second cell structure fastened to an inner contour of a cell of the first cell structure at two fastening points and configured to move radially outward relative to the first cell structure so that an outer contour of the base body is formed by the first cell structure and the second cell structure.

The invention makes available a multi-part implant (10), comprising: a support element (20) for fixing the implant (10) to a bone material; wherein the support element (20) forms a receiving space; and a functional element (30) that can be introduced into the receiving space; wherein the functional element (30) can be fixed in the receiving space (26) by the support element (20) at least with respect to one degree of freedom.

A blood filter delivery system for delivering a filter into a vein from either a femoral or jugular access. The preferred system includes an introducer and a push-rod with a spline member disposed along the push-rod and a pusher member disposed on a distal end. The spline member has a main body, first and second boss portions spaced apart along the longitudinal axis to provide a gap for retaining anchor members of the filter during delivery via the introducer. In an alternative embodiment, a preferred filter includes first and second filter structures diverging in opposite directions. A link is connected to portions of each of the first and second filter structures so that each filter structure can be independently collapsed into a generally cylindrical shape.
