Development of implantable devices and specific instruments used in minimally invasive surgery - Titanio

This activity is based on the development of minimally invasive surgery, the development of support technology to the reconstruction and regeneration of tissue, as well as the design and manufacture of metallic porous structures (scaffolds).This activity is based on the development of new techniques which prevent the implantation of synthetic devices with substitute function and promote the reconstruction or the tissue regeneration.

Description

The Instituto Tecnológico de Canarias (ITC), has worked for a decade in collaboration with a multidisciplinary team (doctors, engineers, physicists, pharmacists, veterinarians) in the development of medical devices (implants and instruments), with applications in orthopedic, traumatology and cardiovascular surgery. This group has consolidated over recent years in a regional and multi-institutional working platform, MOTIVA, exclusively dedicated to minimally invasive surgery, reconstructive and regenerative.
In this line of work, we are studying the geometry of the implants, traditionally solids (due to limitations imposed by the manufacture process) and exploring new three-dimensional geometries with hollow structures and controlled variable porosity. The concept is simple and is to leave as much space as possible free, to populate it with biological tissue, optimizing implant design and without compromising their mechanical stability. This path has led to the acquisition an emerging technology of additive manufacturing (ARCAM, EBM Electron Beam Melting) from powdered metal (Ti6Al4V titanium alloy) that allows us to manufacture the first metallic scaffolds design.
At present, the ITC has permission to manufacture custom implants at nationally, and offer tailored and customized solutions to clinical cases of complex resolution.

Results

In consonance with this line of work, has been carried out successfully the installation and start up of the machine with additive manufacturing technology (Electron Beam Melting, EBM) in the ITC, a technology that allows to manufacture metal scaffolds for filling with biomaterials as a basis for cell growth .
Our Department has been working on the process relating to the design of custom implants, particularly in the development of three-dimensional structures with controlled variable porosity (metal scaffolds), manufactured by EBM technology.
Currently, our Department has already designed and manufactured the metal devices to the initial clinical tests in animals and has obtained the authorization to manufacture custom implants for humans.

Target Audience

The end user is the hospital patient who needs some bone reconstruction or tissue regeneration, prescribed by the doctor.
