| abstract |
The invention broadly provides an implantable medical device comprising a liquid rope coil scaffold. The implant may consist essentially of the scaffold, where the scaffold is the implant and pores in the scaffold may incorporates one or more agents (i.e. drugs, growth factors), or the scaffold may comprise only part of the medical device, for example an implant that is partly or fully covered with a layer of the scaffold. The porosity of the scaffold may be tailored to suit the application, for example a porosity that is tailored to hold and release drug or biological molecules in vivo, a porosity to provide a surface roughness that is conducive to promotion of in-vivo bio-integration (for example vascularisation) or prevention of fibrosis, or a porosity that provides structural strength. The scaffold may be essentially tubular, or may be provided as a planar structure, or may be any shape and can be used to coat, fully or partially any shape or size of medical implant. |
