Abstract: The present disclosure relates generally to the field of tissue removal and more particularly to methods and devices for use in medical applications involving selective tissue removal. One exemplary method includes the steps of providing a tissue cutting instrument capable of distinguishing between target tissue to be removed and non-target tissue, urging the instrument against the target tissue and the non-target tissue, and allowing the instrument to cut the target tissue while automatically avoiding cutting of non-target tissue. Various tools for carrying out this method are also described.

Abstract: Embodiments are directed to methods of producing devices using modified multi-layer, multi-material electrochemical fabrication processes and/or using a laser cutting processes wherein individual layers or layer groups are formed and then stacked and bonded to produce prototypes or production parts. The methods can reduce the cost and lead time of prototyping when compared with previous multi-layer, multi-material electrochemical fabrication processes and can also reduce the lead time of production quantities, by allowing multiple layers of a multilayer device to be formed simultaneously, e.g. in parallel on the same wafer. Additionally, these methods may be used to extend the maximum height to which parts may practically be made. Finally, the methods allow geometries that are impossible, impractical or difficult to release (e.g. microfluidic devices such as pumps or parts with long, narrow channels) to be fabricated in multiple pieces and then joined after full or partial release.

Abstract: Numerous electrochemical fabrication methods and apparatus are provided for producing multi-layer structures (e.g. having meso-scale or micro-scale features) from a plurality of layers of deposited materials using adhered masks (e.g. formed from liquid photoresist or dry film), where two or more materials may be provided per layer where at least one of the materials is a structural material and one or more of any other materials may be a sacrificial material which will be removed after formation of the structure. Materials may comprise conductive materials that are electrodeposited or deposited in an electroless manner. In some embodiments special care is undertaken to ensure alignment between patterns formed on successive layers.

Abstract: Electrochemical fabrication processes and apparatus for producing single layer or multi-layer structures where each layer includes the deposition of at least two materials and wherein the formation of at least some layers includes operations for reducing stress and/or curvature distortion when the structure is released from a sacrificial material which surrounded it during formation and possibly when released from a substrate on which it was formed. Six primary groups of embodiments are presented which are divide into eleven primary embodiments. Some embodiments attempt to remove stress to minimize distortion while others attempt to balance stress to minimize distortion.
