Devices and methods for cooling vessel walls to inhibit restenosis in conjunction with medical procedures such as coronary artery angioplasty. Stenosed vessel walls can be cooled prior to angioplasty, after angioplasty, or both. The invention is believed to inhibit restenosis through cooling to a temperature near freezing, preferably without causing substantial vessel wall cell death. One catheter device includes a distal tube region having coolant delivery holes radially and longitudinally distributed along the distal region. In some devices, holes spray coolant directly onto the vessel walls, with the coolant absorbed into the blood stream. In other embodiments, a balloon or envelope is interposed between the coolant and the vessel walls and the coolant returned out of the catheter through a coolant return lumen. Some direct spray devices include an occlusion device to restrict blood now past the region being cooled. Pressure, temperature, and ultrasonic probes are included in some cooling catheters. Pressure control valves are included in some devices to regulate balloon interior pressure within acceptable limits. In applications using liquid carbon dioxide as coolant, the balloon interior pressure can be maintained above the triple point of carbon dioxide to inhibit dry ice formation. Some cooling catheters are coiled perfusion catheters supporting longer cooling periods by allowing perfusing blood flow simultaneously with vessel wall cooling. One coiled catheter is biased to assume a coiled shape when unconstrained and can be introduced into the body in a relatively straight shape, having a stiffeninig wire inserted through the coil strands.

A method and apparatus for applying tape tabs to a traveling web of material, for example, placement of tape tabs on a running web of disposable undergarments. A pair of wheels each has a protuberance come in contact with the running web of material, which comes in contact with an infeeding tape web. The invention allows placement of tape tabs at asymmetrical spacings, where placement of the tape from contact of the first wheel and protuberance may not be equally or centrally spaced from placement of the tape by the second wheel and protuberance.

System and method for developing a treatment plan for achieving a treatment goal including creating a virtual model of a dental patient's dentition; transforming the virtual model of the dentition using virtual prosthodontics to facilitate achievement of the treatment goal; transforming the virtual model of the dentition using virtual orthodontics to facilitate achievement of the treatment goal; iterating on the transforming steps until substantially achieving the treatment goal; and generating an orthodontic treatment plan and a prosthodontic treatment plan based upon the substantially achieved treatment goal

Process and device for precipitating solid compounds from zinc metal baths. Partial amounts of the metal phase containing these compounds are exposed to an acceleration higher than gravity and dissociated into fractions containing heavier or lighter components. The molten mass depleted of solid compounds is returned to the metal bath. The device has a hollow rotary body for introduction into the molten mass and provided with a discharge opening for the depleted molten mass and a discharge opening for the liquid metal enriched with the solid compounds.

A method and apparatus to improve the read / write performance of a hard drive is presented. A device having solid state, non-volatile (NV) memory is added in-line to the conventional hard drive and acts as a read / write cache. Data specified by the operating system is stored in the NV memory. The operating system provides a list of data to be put in NV memory. The data includes data to be pinned in NV memory and data that is dynamic. Pinned data persists in NV memory until the operating system commands it to be flushed. Dynamic data can be flushed by the hard drive controller. Data sent by an application for storage is temporarily stored in NV memory in data blocks until the operating system commits it to the disk.
