Abstract :
A family of precision rotary micro-cutting tools fabricated using a combination of established micromachining technologies is described. The micro-cutting tools utilize molding/electroplating technologies to realize the cutting wheel, silicon etching to form the housing for the tool, and low temperature bonding to package the device. The device is driven using a variety of low viscosity fluids, which are directed through formed micro-channels. Potential applications of these devices are endoscopic tools for precision incisions and transections of body tissues as well as for performing other vital surgical functions. In addition, these micro-cutting tools can be used in applications where the cutting surface is not directly exposed for laser ablation (e.g. the interior of obstructed vessels and tubes)
