Medical/Surgical Implant
The present invention relates to the field of implants. In particular, the present invention relates to an implant for tissue reconstruction which comprises a scaffold structure that includes a void system for the generation of prevascularized connective tissue with void spaces for cell and/or tissue transplantation. Moreover, the present invention relates to a method of manufacturing such an implant, to the internal architecture of such an implant, to a removal tool for mechanical removal of space-occupying structures from such an implant, to a kit comprising such an implant and such a removal tool, to a removal device for the removal of superparamagnetic or ferromagnetic space-occupying structures from such an implant, as well as to a guiding device for providing feedback to a surgeon during the procedure of introducing transplantation cells into the void spaces generated upon removal of space-occupying structures from such an implant.
Method and apparatus for treating bone fractures, and/or for fortifying and/or augmenting bone, including the provision and use of composite implants, and novel composite structures which may be used for medical and non-medical applications
A composite comprising: a barrier, said barrier being configured to selectively pass water, and said barrier being degradable in the presence of water; a matrix material for disposition within said barrier, wherein said matrix material has a flowable state and a set state, and wherein said matrix material is degradable in the presence of water; and at least one reinforcing element for disposition within said barrier and integration with said matrix material, wherein said at least one reinforcing element is degradable in the presence of water, and further wherein, upon the degradation of said at least one reinforcing element in the presence of water, provides an agent for modulating the degradation rate of said matrix material in the presence of water.
Scaffold for living donor transplantation
Disclosed is a scaffold for living donor transplantation, which includes sintered bioglass and a biocompatible polymer and has improved properties using a 3D printer through a fused deposition modeling process.
BIOLOGIC COMPOSITION AND METHOD OF MANUFACTURE
A biological composition has a mixture of mechanically selected allogeneic biologic material derived from bone marrow. The mixture has non-whole cellular components including vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, cellular derivatives, and extracellular components. The mixture is compatible with biologic function.

BONE REGENERATION MATERIAL HAVING A COTTON-WOOL LIKE STRUCTURE FORMED OF A PLURALITY OF ELECTROSPUN FIBERS
A bone regeneration material has a cotton-wool like structure formed of a plurality of electrospun fibers that contain bound BMP-2 through -TCP binding peptide. The electrospun biodegradable fiber contains 25-65 vol % of -TCP particles distributed in the fiber such that a portion of the -TCP particles is exposed on a surface of the electrospun fiber and the remaining portion of the -TCP particles is buried in the fiber. -TCP binding peptides that are fused with BMP-2 are bound to the -TCP particles so that BMP-2 is tethered to -TCP particles on the surface of the fibers. Upon implantation of the bone regeneration material in a bone defect site of a human body, BMP-2 that are tethered to -TCP particles on the surface of the bone regeneration material promotes proliferation and differentiation of cells at the bone defect site.
PROSTHESIS FOR HIP REPLACEMENT WITH POLYETHYLENE HEAD AND ANTI-ROTATIONAL INTRA-PROSTHETIC ASSEMBLY
This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.
