Innovation Research

Our Centre focuses on two flagship research themes, split into smaller projects which address some of the key challenges facing medical device manufacturers and healthcare providers.

Theme 1: Stratified design & manufacture

Across all markets there is a demand for increased reliability and assurance of throughout lifetime performance of medical devices. Enhanced pre-clinical simulation and fuller evaluations of medical devices are necessary to meet the requirements of new developments in the regulatory framework for medical devices. These new developments include increasing stringency in regulation and the global harmonisation for regulatory approval, both of which increase the cost of compliance for manufacturing companies.

In the developed world and tier one markets, patients are demanding earlier intervention and tissue preservation, which requires enhanced diagnostics and increased levels of personalisation. New approaches to design and manufacturing and new materials technologies are needed to deliver this within the existing cost envelope; supported by less invasive surgery and shorter hospital stays.

Our research, which is split into four distinct projects, will address increased functional stratification to produce more robust design, manufacture and deployment processes to accommodate variations in patients, populations and surgery.

Project 1B: Stratified bioprocesses for the manufacture of acellular scaffolds (opens PDF)

Project 1C: Stratified design & manufacture of nonwoven collagen scaffolds (opens PDF)

Project 1D: Manufacture of fully bioresorbable multiphase fixation devices to order (opens PDF)

 

Theme 2: Manufacturing at the point of need

Manufacturing at the point of need is central to developing processes which are (where possible) minimally invasive and that can effectively deliver bioactive materials. One of the major drivers for novel surgical interventions is to decrease the anatomical injury at surgery, reduce patient time in patients and accelerate the rate of recovery .

The last decade has seen significant growth in research into biofabrication and many approaches have been developed. However many of these suffer from limitations, in particular in relation to structural materials being too soft to provide significant support in clinical applications.

This research theme will address defects in the musculoskeletal system as early as possible, through the development of more robust structural bioactive materials, such as bioactive glass-ceramics and biopolymers. It will also examine the potential for enhancement of devices using biomolecules and the optimisation of devices to enable them to interact with cells added at the site of implantation or those that have been therapeutically added.

Feasibility studies

MeDe Innovation is widening the national reach of its research by awarding feasibility study funding to shape the future direction of the Centre.

Eight of the UKs leading scientists, engineers and clinicians have been granted awards of  £50k to identify the key challenges and questions that are not currently being addressed in orthopaedic medical device design and manufacture research.

The funds will allow investigators to develop the evidence and refine the research questions that will allow the development of full proposals for funding that can be submitted to existing national and global funding schemes.

A panel of leaders from industry and academia selected the winners from nominations put forward by over 20 universities and companies. The winners showed an exemplary fit with the research challenges being led by the Centre, offered significant  potential and had support from industry:
