Objectives and Approach

The IMICS project is concerned with the development of micro-mechanical and microelectronic components and subsystems, and their integration into an advanced cardiac catheter system for plaque removal. More specifically, the project will aim to develop a system which integrates the sensing and signal processing (diagnostic) function with the microactuating (therapeutic) function in a catheter head of overall external diameter between 2 and 4 mm. To achieve this objective, efforts will be focused on the following areas:

It will be based on a series of expandable units, constructed using biocompatible balloon technology, which, by dilation, will be brought into contact with the artery wall by means of an array of active micro-valves.

Successful integration will hinge on the development of novel techniques for fabricating, handling and assembling submillimetre and micron scale sub-assemblies and components, while assessment and evaluation of the biocompatibility and reliability of catheter materials and components will form a significant element in the programme.
