Title: Transesophageal ultrasound using a narrow probe
Inventor: ROTH SCOTT L
IPC: G01S15/89
Filed: 2004-11-24
Abstract: Transesophageal echocardiography is implemented using a miniature transversely oriented transducer that is preferably small enough to fit in a 7.5 mm diameter probe, and most preferably small enough to fit in a 5 mm diameter probe. Signal processing techniques improve the depth of penetration to the point where the complete trans-gastric short axis view of the left ventricle can be obtained, despite the fact that the transducer is so small. The reduced diameter of the probe (as compared to prior art probes) reduces risks to patients, reduces or eliminates the need for anesthesia, and permits long term direct-visualization monitoring of patients' cardiac function.

Title: Improved eccentric drive shaft for atherectomy device
Inventor: SHTURMAN LEONID
IPC: A61B17/3207
Filed: 1999-03-17
Abstract: This invention is an improved rotational atherectomy drive shaft (20) having an asymmetrical tissue removal section (28). One or more strands of wire are helically wound about an elongated mandrel having an enlarged diameter section (28) with a predetermined shape, thereby forming an elongated, flexible drive shaft (20) which has an enlarged diameter tissue removal section (28). A protion of the drive shaft (20), including the enlarged diameter tissue removal section (28) is placed into a first clamp, and given a first heat treatment to give the wire turns (31) of the enlarged diameter tissue removal section an initial set, thereby preserving the initial shape of the enlarged diameter tissue removal section (28) of the drive shaft (20). The drive shaft (20) is then removed from the first clamp, and the mandrel (50) is dissolved. The enlarged diameter section (28) of the drive shaft (20) is then deformed to an asymmetrical shape by placing a portion of the drive shaft (20), including the enlarged diameter tissue removal section (28) into a second clamp. The clamped portion of the drive shaft (20) is then heat treated for a second time to give wire turns (31) of the enlarged diameter tissue removal section (28) a new set, thereby preserving the asymmetrical shape of the enlarged diameter section (28). In its asymmetrical shape the enlarged diameter tissue removal section (28) has a longitudinally flat'side', i.e., all wire turns of the tissue removal section may be connected by an imaginary straight line which throughout its length is parallel to the rotational axis of the driveshaft.

Title: Process for pre-hydrolysis of biomass
Inventor: GUEDES SOARES ALVARO
IPC: C13B10/14
Filed: 2000-06-23
Abstract: This invention refers to a process carried out in an apparatus for the processing of pre-hydrolysis of biomass, particularly a reactor of the failsafe type, either mobile or not, which may be manufactured of microbonded carbon steel and coated with special materials (refractory metals, superalloys, stainless materials, plastics, etc.). The insertion of vacuum between the shell of the reactor and its coating prevents its implosion and permits the detection of leakage with helium gas. The resistance to corrosion of the refractory metals enables carrying out of pre-hydrolysis and mineral digestion. In the process of this invention, biomass is compacted at 300 kg/m3 by a helical feeder, degased, flooded, heated, stirred, pre-hydrolyzed, the sugar being recovered at a first washing within the reactor with values higher than 90 %. The low liquid/solid ratio = 2 enables one to achieve sugar content of 10 bricks in the prehydrolysate and a consumption of % of the energy contained in the processed biomass. The pre-hydrolysate is constituted by solutions of xylose and others and is intended for the production of furfural, alcohol and xylitol. The control of the process enables one to produce cellulignin with a high specific surface, 2 m2/g (measured by BET), compared with the value of 0.4 m2/g of nonhydrolyzed biomass, maintain crystallinity of the cellulose fibers, aiming at grinding it into fine particles (f<)250 mm), globulizing the lignin, exposing the cellulose to attacks by microorganisms from cud of ruminants, fungi, bacteria or enzymes in microbiological or enzymatic fermentation. The catalytic combustion due to the large specific surface results in a new fuel for boilers, combustors in general and MHD when produced with filtered water, and for gas turbines when produced with deionized water.
