    摘要: The present invention relates to a method for preparing a bone repair material comprising a porous block-shaped scaffold containing a crosslinked polyethylene glycol hydrogel formed by a Michael type addition of at least two precursor molecules. Said scaffold is made of a synthetic ceramic material and comprises interconnected macropores having a diameter of at least 100 um. In addition the scaffold has a total porosity of 60 to less than 80%. The method comprises the steps : (a) mixing an aqueous solution comprising a first precursor with an aqueous solution comprising a second precursor, whereby the total concentration of the first and the second precursor in the mixture is less than the equilibrium concentration of the hydrogel, (b) adding the mixture of step a) to the porous block-shaped scaffold, and (c) vacuuming the bone repair material obtained in step c), to allow reaction between the first and the second precursor.

    摘要: Deflectable implants, systems and methods for implanting deflectable implants are disclosed. The deflectable implant (100) includes at least one sequence of segments (102), the sequence includes at least two segments (102), the segments (102) being interconnected at effective hinges (107), the sequence assuming a straightened or low curvature insertion state for insertion into the body, the sequence being deflectable to a fully deflected state defined by abutment of abutment features of adjacent of the segments (102). The deflectable implant (100) includes further a linkage mechanically linked to at least part of at least one of the sequences of segments (102) for deflecting the at least one sequence of segments (102) from the insertion state towards the fully deflected state wherein the at least one sequence is at least part of a loop structure assuming a low profile folded state with the at least one sequence towards the fully deflected state generates an open state of the loop structure and wherein the loop defines an enclosed volume (106).
