    摘要: Systems for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

    摘要: The present invention provides methods and apparatus for selectively patterning surfaces using radical species generated with a photocatalyst. The photocatalyst may comprise a photocatalytic semiconductor or a photosensitizer. The radical species are brought into contact with an oxidizable coating disposed on the surface, thereby locally oxidizing and selectively patterning the surface. The photocatalyst is preferably disposed on a delivery device, such as a stamp, mask, or scanning probe, that is brought into close proximity or contact with the coated surface. The photocatalyst is then excited in a manner capable of generating radical species, for example, oxygen-containing radical species, in appropriate media. It is expected that these radical species will be transferred to the coated surface along a substantially shortest distance path, thereby locally oxidizing and patterning the surface.
