The goal of the InForMed project is to establish an integrated pilot line for medical devices. The pilot line includes micro-fabrication, assembly and even the fabrication of smart catheters. The heart of this chain is the micro-fabrication and assembly facility of Philips Innovation Services, which will be qualified for small/medium-scale production of medical devices. The pilot facility will be open to other users for pilot production and product validation. It is the aim of the pilot line: to safeguard and consolidate Europes strong position in traditional medical diagnostic equipment, to enable emerging markets - especially in smart minimally invasive instruments and point-of-care diagnostic equipment - and to stimulate the development of entirely new markets, by providing an industrial micro-fabrication and assembly facility where new materials can be processed and assembled. The pilot line will be integrated in a complete innovation value chain from technology concept to high-volume production and system qualification. Protocols will be developed to ensure an efficient technology transfer between the different links in the value chain. Six challenging demonstrators products will be realized that address societal challenges in: Hospital and Heuristic Care and Home care and well-being, and demonstrate the trend towards Smart Health solutions.

SMARTool aims at developing a platform based on cloud technology, for the management of patients with coronary artery disease (CAD) by standardizing and integrating heterogeneous health data, including those from key enabling technologies. The platform includes existing multiscale and multilevel ARTreat (FP7-224297) models of coronary plaque progression based on non-invasive coronary CT angiography (CCTA) and fractional flow reserve computation, refined by heterogeneous patient-specific non-imaging data (history, lifestyle, exposome, biohumoral data, genotyping) and cellular/molecular markers derivable from a microfluidic device for on-chip blood analysis. SMARTool models will be applied and validated by historical and newly acquired CCTA imaging plus non-imaging health data from the EVINCI project (FP7-222915) population. SMARTool cloud-based platform, through Human Computer Interaction techniques, 3D visual representation and artery models, will use heterogeneous data in a standardized format as input, providing as output a CDSS - assisted by a microfluidic device as a point of care testing of inflammatory markers for: i) Patient specific CAD stratification - existing models, based on clinical risk factors, will be implemented by patient genotyping and phenotyping to stratify patients with non-obstructive CAD, obstructive CAD and those without CAD, ii) site specific plaque progression prediction - existing multiscale and multilevel ARTreat tools of CAD progression prediction will be refined by genotyping and phenotyping parameters and tested by baseline and follow CCTA and integrated by non-imaging patient-specific data, iii) patient-specific CAD diagnosis and treatment - life style changes, standard or high intensity medical therapy and a virtual angioplasty tool to provide the optimal stent type(s) and site(s) for appropriate deployment.

A mixing assembly includes an inlet, an outlet and a mixing chamber, the inlet is fluidly connected to the outlet through a plurality of micro fluid flow paths in a direction perpendicular from the inlet. The micro fluid flow paths fluidly connect to the perpendicular inlet via a transition portion. The micro fluid flow paths are constructed radially inwardly to a concentration area in the mixing chamber. By directing multiple fluid flows to a concentrated area within the mixing chamber at high speeds, the energy dissipated at the point of collision is maximized, which helps to increase consistency and quality of mixing, and to reduce particle size of the fluid in the mixing chamber.
