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 ...

THREE TO FOUR MILLION YOUNG CHILDREN FROM ALL LEVELS OF SOCIETY ARE EXPOSED TO ENVIRONMENTAL SOURCES OF LEAD AT CONCENTRATIONS THAT PLACE THEM AT RISK FOR ADVERSE HEALTH EFFECTS. YET, THERE IS NO TOOL AVAILABLE FOR MEASURING TOTAL PEDIATRIC BODY BURDEN OF LEAD. THIS PROJECT WILL DEVELOP AN X-RAY FLUORESCENCE (XRF) INSTRUMENT THAT WILL ALLOW MEASUREMENT OF BODY LEAD BURDEN IN CHILDREN IN VIVO AND N ...

CENTRIFUGAL BLOOD PUMPS HAVE BEEN USED EXTENSIVELY FOR SHORT-TERM CIRCULATORY ASSISTANCE AND PERFUSION PUMPS. THEIR UTILITY FOR LONG-TERM VENTRICULAR ASSISTANCE IS LIMITED BY THROMBUS FORMATION AT THE SHAFT SEAL. ABIOMED, INC., WILL DEVELOP A MAGNETICALLY SUSPENDED CENTRIFUGAL BLOOD PUMP THAT WILL HAVE NO SHAFT SEAL AND BE SUITABLE FOR LONG-TERM CIRCULATORY SUPPORT IN EITHER AN IMPLANTED OR EXTRAC ...

THIS RESEARCH WILL DEMONSTRATE THAT A NEW 1.9-MU M LASER CAN PERFORM LASER-ASSISTED VASCULAR ANASTOMOSES OF SMALL-DIAMETER VESSELS (1 TO 5 MM). THE 1.9-MU M LIGHT HAS OPTIMAL ABSORPTION CHARACTERISTICS TO ENSURE AN EVEN DEPOSITION OF ENERGY IN THE VESSEL WALL. THIS SHOULD RESULTIN A MORE DESIRED TEMPERATURE PROFILE IN THE REGION OF THE ANASTOMOSIS WHEN COMPARED WITH ALTERNATIVE SOURCES. THE PROPOS ...

THE OBJECTIVE IS TO DEVELOP A PERIODONTAL PROBE CAPABLE OF MEASURING SITE TEMPERATURE AND POCKET DEPTH SIMULTANEOUSLY AND AUTOMATICALLY. THE PROBE IS INTENDED TO BE A RAPID SCREENING DEVICE FOR THE STATE OF PERIODONTAL HEALTH DURING ROUTINE DENTAL EXAMINATIONS. STUDIES HAVE SHOWN THAT THE INFLAMED SULCUS IS ACCOMPANIED BY ELEVATED SITE TEMPERATURES. POCKET DEPTHS ARE ROUTINELY MEASURED DURING DENT ...

A bearingless disposable centrifugal blood pump will be developed in this project, together with ainexpensive driver and controller. The rotor of the pump will be suspended by a combination of magnethat it is washed on all surfaces by moving blood. The elimination of bearings and shaft seals removheating and blood stagnation, making such a pump safer and more reliable for short to medium term usp ...

Our objective is to develop a laser welding technique for applications in urologic anastomotic repalaparoscopic procedures in which conventional suturing techniques are difficult. The project is desistrength of welds in a bladder augmentation procedure (enterocystoplasty) under feedback controlledmode to achieve desired preset surface temperature of the tissue favorable to reproducible weld intewi ...
