Estimating the term…
The present invention relates generally to biocompatible medical devices, such as cranial implants, and a method and means of attaching to hone. More specifically, the present invention relates to multilayered porous material with controlled porosity and drug load designed to control the release of drugs from a medical device. Additionally the present invention provides methods for controlling release of drugs by integrating the multilayer structure in medical devices with successive layers of polymer coatings of different porosities and drug contents. The multilayer material is inserted in between two plates such as meshes that provide strength to the implant. The present invention relates to biocompatible medical devices that has osseointegration and antibacterial properties. The present invention also relates to a method and means of attaching the medical device to defect in a bone structure and comprises of tree mounting parts configured to secure the medical in place.
An implantable biocompatible medical device wherein the implant comprises two mashes having osseointegration properties and one multilayer porous material with controlled release properties that is placed in between the 2 mashes, comprising a multi drug-containing polymer layers having porosity gradient to control the release of the drugs, where the external drug-containing polymer layer have porosity values and the inner drug-containing polymer layers have different porosity values, wherein said inner porosity values are less than said external porosity values.
An assembly for attaching the medical device to the edge of the detect with clamps, wherein the first mesh rests and attached to the base of the clamp allowing for further loading the multilayer material, and the second mesh closes the implant assembly and is fastened by the clamps, wherein the medical device acts as an effective releaser of controlled amount of pharmaceutic drugs.
A method for fixing the implantable medical device in the skull that includes a clamping system that attaches the implantable medical device the skull by clamping the inner and the external surface of the skull to the implantable medical device.
