Inventor: ATOJI TADASHI
IPC: H01L21/304
Filed: 1996-12-11
Granted: 2001-03-13
Abstract: The conventional fabrication processes of SOI substrate employed wet etching for removing a porous single-crystal Si region, but wet etching involved difficulties in management of concentration for fabricating SOI substrates in high volume, which caused reduction in productivity.     Therefore, provided is a fabrication process of SOI substrate comprises a step of forming a non-porous single-crystal Si region on a surface of a porous single-crystal Si region of a single-crystal Si substrate having at least the porous single-crystal Si region, a step of bonding a support substrate through an insulating region to a surface of the non-porous single-crystal Si region, and a step of removing the porous single-crystal Si region, wherein the step of removing the porous single-crystal Si region comprises a step of performing dry etching in which an etch rate of the porous single-crystal Si region is greater than that of the non-porous single-crystal Si region.

Title: Method of catheter balloon manufacture and use
Inventor: TROTTA THOMAS N
IPC: A61F2/958
Filed: 1997-03-17
Granted: 2010-08-31
Abstract: A catheter balloon is prepared for inflation, and the balloon is inflated by the following process. At least a portion of an elastic, thermoplastic tube is radially stretched until the radially stretched tube portion exhibits a desired increase in molecular orientation. The stretching conditions, such as selective heating, preferably cause a central section of the stretched tube portion to have less wall thickness than end sections of the tube portion. At least part of the tube portion may be longitudinally stretched relative to the tube, to create a desired biaxial molecular orientation. Thereafter, the tube portion is optionally placed into a stent, the tube portion being part of a catheter. The tube portion is inserted into a patient to position the stent and tube portion at a desired position, such as a location in the coronary artery. After positioning of the tube portion and stent, the lumen of the tube portion is pressurized to cause radial expansion of the tube portion within the patient, with a central section of the tube portion expanding first.

Abstract: A method in which natural sample components are simultaneously fractionated and screened for compounds that bind tightly to specific molecules of interest is disclosed. Such newly isolated ligands are good candidates for potential therapeutic or diagnostic compounds. The natural sample is first combined with a potential target molecule and then subjected to capillary eiectrophoresis (CE). Charged (or even neutral) compounds present in the natural sample that bind to the added target molecule can alter its normal migration time upon CE, by changing its charge-to-mass ratio, or will cause a variation in peak shape or area. Complex formation can lie detected by simply monitoring the migration of the target molecule during electrophoresis. Any new ligands that bind to the target molecule wilt be good candidates for therapeutic or diagnostic compounds. Interfering, weak-binding ligands commonly present in crude extracts are not detected. Small, neutral ligands, as well as charged ligands, can be identified in competitive binding experiments with known, charged competitor molecules.

Abstract: Biodegradable polymer networks are provided which are useful in a variety of dental and orthopedic applications. The biodegradable polymer networks can be formed in one embodiment by polymerizing anhydride prepolymers including cross-linkable groups, such as unsaturated moieties. The anhydride prepolymers can be cross-linked, for example in a photopolymerization reaction by irradiation of the prepolymer with light in the presence of a free radical initiator. Suitable anhydride prepolymers include dianhydrides of a dicarboxylic acid and a carboxylic acid molecule comprising a cross-linkable group. For exampl e, methacrylic acid dianhydrides of monomers or oligomers of a diacid such as sebacic acid or 1,3-bis(p-carboxyphenoxy)-hexane can be used. The anhydride prepolymers can be applied in vivo to a site where an orthopedic implant is needed, and then may be cross-linke d, for example, by irradiation with UV light, to form a biodegradable implant such as a rod, pin or plate. The implants advantageous ly provide mechanical support and also are capable of slow surface degradation to permit bone ingrowth.
