The present invention provides systems and methods for guiding a surgical instrument (212) into a preselected spatial relationship with a lesion (234) , in particular a lesion of the breast. In an exemplary embodiment, the system includes a data translation system that translates a set of data points representing the position of the lesion into a set of three-dimensional coordinates. It also incl...

Mutants of the human PAI-1 protein are described which are inhibitors of neutrophil elastase or are inhibitors of vitronectin (Vn)-dependent cell migration. These mutants preferably comprise one or two amino acid substitutions in the reactive center loop of PAI-1, particularly at positions 331 and 346 of the mature protein. These mutants are notable in being resistant to inactivation by elastase, ...

A first stream of air is compressed in a main air compressor 2 and a booster compressor 6, is cooled at a first pressure by passage through a main heat exchanger 8. The cooled stream is introduced without further compression into the higher pressure column 18 of a double rectification column 16 including in addition to the column 16 a lower pressure column 20 and a condenser-reboiler 22. A second ...

A mattress cover (C) comprises mattress top (1) and bottom (2) cover layers, a cover side wall (3) in the form of a band extending around perimeters of the cover layers, the side wall incorporating releasable fastener means (5) extending for a substantial portion of its perimeter intermediate its edges for opening and closing the side wall over the substantial portion of its perimeter, the edges o...

Electrode assemblies (56) actively cool mucosal surface tissue at or near a sphincter while applying energy through an electrode to heat tissue beneath the surface. The applied energy creates one or more lesions beneath the mucosal surface. Natural healing of the subsurface lesions leads to a physical tightening of the sphincter. The active surface cooling preserves, and protects the mucosal surfa...

Improved electrode assemblies for treating a tissue region at or near a sphincter comprises a support structure (135), and an electrode (66) carried by the support structure for advancement in a path to penetrate the tissue. In one arrangement, the electrode (66) has a non-cylindrical cross section selected to resist deflection when advanced to penetrate tissue. In another arrangement, the electro...

The disclosed bladder (10) is useful in ambient temperature fabrication of rubber parts and components. Due to the particular combination of construction materials used, the bladder has excellent release properties and results in improved manufacturing uniformity. At least one portion of the bladder (10) is formed from a lack tack, high abrasion resistant polyurethane. The polyurethane may compris...

The present invention is a radiation-curable coating composition which comprises (A) a specified amino-group-containing alkoxysilane such as N- beta -(N-vinylbenzylaminoethyl)- gamma -aminopropyltrimethoxysilane, and (B) an acrylic polymer.
