Abstract: Embodiments of invention are directed to tissue approximation instruments that may be delivered to the body of a patient during minimally invasive or other surgical procedures. In one group of embodiments, the instrument has an elongated configuration with two sets of expandable wings that each have spreadable wings that can be made to expand when located on opposite sides of a distal tissue region and a proximal tissue region and can then be made to move toward one another to bring the two tissue regions into a more proximate position. The instrument is delivered through a needle or catheter and is controlled by relative movement of a push tube and control wire wherein the control wire can be released from the instrument via rotation in a first direction and can cause release of the approximation device from tissue that it is holding by rotation in the opposite direction.

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: RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations and/or from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, hybrid couplers, antenna arrays and/or other active or passive components. Components may include non-radiation-entry and non-radiation-exit channels that are useful in separating sacrificial materials from structural materials. Preferred formation processes use electrochemical fabrication techniques (e.g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e.g. selective etching operations and/or back filling operations).

Abstract: Embodiments of the invention provide threaded elements alone, in mating pairs, or in conjunction with other elements. Embodiments of the invention also provide for design and fabrication of such threaded elements without violating minimum feature size design rules or causing other interference issues that may result from the fabrication of such thread elements using a multi-layer multi-material electrochemical fabrication process.
