BONE IMPLANT HAVING COATED POROUS STRUCTURE

The invention relates to a bone implant, comprising a main body, which has, in its outer region, an open-cell porous lattice structure, which is formed from a plurality of regularly arranged elementary cells, the elementary cells being in the form of an assembled structure and each being composed of an interior and of a plurality of interconnected bars surrounding the interior. The porous lattice structure is provided with a bone-growth-promoting coating comprising calcium phosphate, the calcium phosphate coating having a hydroxylapatite proportion forming a pore inner coating extending into the depth of the porous lattice structure.

SURGICAL MEMBRANE

A surgical membrane for supporting bone growth comprises a surface configured for receiving a surface functionalisation agent capable of promoting cell adhesion and proliferation and/or of reducing bacterial growth on said surface. The membrane is also subjected to a treatment improving the wettability of the surface.

PLASMA ION PROCESSING OF SUBSTRATES

A method for plasma ion processing is described, including flowing a gas into porous material; and exposing the gas to a pulsed electric field whilst the gas is in the pores. The pulsed electric field ionises the gas to generate a plasma. The method may additionally include exposing the porous material to a gas so as to generate functionality. The method may additionally include exposing the functionalised porous material to a functional species so as to covalently attach said functional species to the surfaces of the pores.

Coating scaffolds

Provided are compositions and methods for a scaffold coated with a primer coating and a mineral coating. Also 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.
