Abstract: A low profile pump inlet for an implantable blood pump is disclosed. The low profile pump inlet has an inflow diffuser for attachment to a conduit bearing an inflow of a fluid such as blood and an outflow orifice in fluid connection with the diffuser. The outflow orifice is configured to direct the fluid from the diffuser into a pump such as an implantable blood pump. The low profile pump inlet helps to suppress the effects of upstream pipe bends on the blood traveling through the inlet. The inlet thus provides a flow having a substantially uniform velocity profile into the blood pump.

Abstract: A brace apparatus having a core member adapted to absorb energy by undergoing plastic deformation and a buckling restraining assembly that maintains the structural integrity of the brace apparatus once the core member has undergone plastic deformation. A core member having a variable width middle portion is provided to control deformation of the core member such that the middle portion center undergoes plastic deformation before the middle portion first and second ends. A core member is provided which includes a core stiffener permitting the brace apparatus to have a longer longer length relative to the core member cross-sectional area while providing both a desired yield point and the stiffness needed rigidity required for structural support. One or more projections are provided having a stress reduction voids which reduce the cross sectional area of the core member to eliminate stress risers that would otherwise be present at the portion of the core member corresponding with the projections.

Abstract: The present invention is directed to a brace apparatus having a core member configured to absorb energy generated by seismic or other forces by undergoing plastic deformation. A buckling restraining assembly is included for maintaining the structural integrity of the brace after the core member has undergone plastic deformation. The buckling restraining assembly includes one or more bearings is located proximal the core member. The bearings are adapted to minimize friction between the core member and the buckling restraining apparatus. An air gap is positioned between the core member and the one or more bearings of the buckling restraining apparatus are adapted to prevent bonding of the core member and buckling restraining assembly. Projections are included in the core member of the brace apparatus to minimize movement of the middle portion of the core member relative to the buckling restraining assembly.
