177 Low-Loss HTS Coil System for High Energy Physics Detector Applications--Ability Engineering Technology, Inc., 16140 Vincennes Avenue, South Holland, IL 60473-1283; Mr. Michael W. Morgan, Principal Investigator Mr. Joseph A. Zawistowski, Business Official DOE Grant No. DE-FG02-97ER82307 Amount: $75,000 The use of high-temperature superconducting (HTS) coils (those that superconduct when co ...

THE OBJECTIVE OF THIS PROGRAM IS TO DESIGN AND BUILD A STAPLER FOR PERFORMING END-TO-END AND END-TO-SIDE ANASTOMOSES ON MEDIUM TO LARGE VESSELS, AND FOR REPAIRING BLOOD VESSELS AND VASCULAR ANEURYSMS, AND TO DEVELOP A SURGICAL PROTOCOL FOR ITS USE. THE METHOD PROPOSED USES A SPECIAL STAPLER AND CONFIGURATION OF STAPLES WHICH MINIMIZESBLOOD CONTACT WITH THE STAPLES, DOES NOT RESTRICT THE FLOW OF BL ...

X-RAY FLUORESCENCE (XRF) IS THE MOST PRECISE METHOD OF MEASURING BODY AND ORGAN BURDENS OF HEAVY METALS IN VIVO. HOWEVER, THE REQUIRED PRECISION FOR SCREENING OF CHRONICALLYLOW-LEVEL-EXPOSED POPULATIONS FOR THESE METALS, IN PARTICULAR LEAD AND MERCURY, IS BETWEEN 5 AND 20 TIMES GREATER THAN ACHIEVABLE BY CURRENT METHODS. THIS PROJECT DESCRIBES AN INNOVATIVE VARIATION OF XRF THAT CAN PROVIDE AN IMP ...

THE EFFECTIVENESS OF INTRA-AORTIC BALLOON PUMP (IABP) THERAPY IS DEPENDENT ON PHYSIOLOGICAL AND PHYSICAL VARIABLES, PERHAPS THE MOST IMPORTANT OF WHICH IS THE SETTING OF IABP TIMING OF INFLATION AND DEFLATION RELATIVE TO THE CARDIAC CYCLE. THE OPTIMIZATION OF TIMING IS CURRENTLY HANDLED MANUALLY, DELEGATED TO A PUMP TECHNICIAN OR PERFUSIONIST, AND IS UPDATED ANYWHERE FROM SEVERAL TIMES AN HOUR TO ...

Endoscopic exploration of the utero-fallopian region is useful and may become a more general observational modality if a viewing instrument can be build with a front end that is disposable and inexpensive, has a small diameter with potential for transcervical introduction without anesthesia, and can provide high image resolution. The goal is the development of a falloposcope with high resolution i ...

The limited availability of donor hearts for people with end stage heart failure has driven the condevelopment of mechanical circulatory support systems (MCSSs). MCSSs can be broadly classified intocontinuous flow systems. Pulsatile systems drive blood indirectly through blood pumps, resulting inThis disadvantage of these systems, however, is their relatively large size. Continuous flow systemssim ...

Minimal access abdominal surgery through the laparoscope has generally replaced surgical procedureslaparotomy for several common procedures, including cholecystectomy and appendectomy. More complicatgastrointestinal operations are also being attempted laparoscopically. Many of these procedures aretechniques which are not yet standard laparoscopic techniques. A basic surgical technique necessarythe ...

Calcification of blood contacting surfaces has been the key impediment to the development of polymevalve prostheses and other polymeric implantables. The deposition of calcium plaques as hydroxyapatiand potentially leads to valve dysfunction. That calcification proceeds preferentially along surfacestress only exacerbates the problem. This work is based on the hypothesis that calcification along fa ...
