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 ...

DESCRIPTION (provided by applicant): The goal of this proposal is to produce a fully characterized polyurethane heart valve prosthesis that will be ready for clinical evaluation. Existing replacement valves suffer from several shortcomings. Specifically, biological tissue fixation and methods used to mount the tissue to the supporting stent of bioprostheses cause time dependent structural changes ...

This Small Business Innovation Research (SBIR) Phase I research research project aims to develop a polymer system for drug eluting coronary stents (DES). The material is expected to provide higher drug loading with a controlled drug release profile, as well as tunable mechanical properties over the lifetime of the stent. This will be accomplished using block terpolymers of specific composition to ...

THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

Realizing the promise of nuclear fusion depends in part on effective plasma facing components (PFCs) that can withstand the intense heat loads, forces, and neutron bombardment of long-pulse high-power reactor operation. A single reactor such as ITER will require thousands of PFCs. Because imperfections in the joints of just one PFC could have disastrous consequences for reactor operation, joint ...

Many military missions involve the use of equipment that requires small batteries for power where AC grid power is unavailable. Also, there is a need for a high quality power output device that conditions a power input to make it suitable to power sensitive communications equipment. The weight of this equipment is also a factor which affects Its usefullness in quick moving military situations. M ...

Solid oxide fuel cells (SOFCs) are one of the most efficient and cleanest power generating systems being developed. A key component is the cathode air heat exchanger, or recuperator, which ensures that the cathode air, and thereby the cells, are at sufficient temperature to permit ion mobility ¿ and thereby improve overall SOFC system efficiency. At present, commercially available metallic recu ...
