The present invention concerns a cage holder including an elongated body comprising a proximal end and a distal end, the elongated body extending from the proximal end to the distal end. The cage holder is characterized in that it further includes means for transferring energy centrally from the proximal end to the distal end through the elongated body.

Provided is a composition for a scaffold having a mineral coating similar to bone. Also provided is a method for mineral coating a scaffold so as to promote mineral coating of the scaffold with a plate-like nanostructure and a carbonate-substituted, calcium-deficient hydroxyapatite phase.

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.

A system and method for altering bone growth on and within an orthopedic implant that includes an implant body; a plurality of electrodes, wherein each electrode is at least partially embedded in the implant body, and comprises: a set of primary electrodes comprising at least one electrode, wherein a non-embedded segment of each primary electrode is proximal to a bone growth region, a set of secondary electrodes comprising at least one electrode, wherein a non-embedded segment of each secondary electrode is distal to the bone growth region, and wherein the plurality of electrodes are configured to function in a stimulation operating mode, such that a subset of primary electrodes function as cathodes and a subset of secondary electrodes function as anodes; a control system comprising a processor, and circuitry that connects to the plurality of electrodes; and a power system.

A system and method for altering bone growth on and within an orthopedic implant comprising an implant body, wherein the implant body comprises an exterior surface and an interior surface defining an internal cavity of the implant body, a plurality of electrodes, wherein each electrode is at least partially embedded in the implant body, and comprises at least, a first set of the plurality of electrodes 116, composed of a first material, and a second set of the plurality of electrodes, composed of a second material; and a control system, comprising a processor and circuitry that connects to the plurality of electrodes, wherein the processor, through operating modes, provides machine instructions to control direction and magnitude of current traveling through each electrode from the plurality of electrodes; and a power system, comprising a power source and circuitry that provides electrical power for function of the plurality of electrodes.

The present invention provides modular transcatheter valve replacement devices and methods of using the same to treat valvular heart diseases. Disclosed is a bottom module that contains a heart valve replacement, and a top module connected to the bottom module. The top module may be bio-absorbable, or may contain one or more severable joints that allow the top module to be removed after implantation. The removable or absorbable top portion serves to add additional length the structure to add in orientation during implantation, but is removed or absorbed to minimize the metal and other foreign material in a patient's body that could cause thrombosis or other reactions.

A stent including a mesh made of strands. The mesh has at least one radiopaque strand and at least one non-radiopaque strand, and the at least one radiopaque strand and the at least one non-radiopaque strand each have different diameters. Each strand has an index of wire stiffness EI, where EI is the mathematical product of the Young's modulus (E) and the second moment of area (I). The EI of all strands in the mesh is no more than five times the EI of the strand having the smallest EI of any of the strands.

Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.
