Abstract: A method for forming a stent in situ involves manipulating a delivery system to provide a mold within a lumen of a living body, and injecting a settable, biocompatible phase invertible composition into the mold. After the biocompatible phase invertible composition is set, the delivery system is removed. The stent provides a micro-porous support structure with good tensile strength that is adhesively bound to the lumen. The biocompatible phase invertible composition may be a composition concocted from albumin and collagen, for example, and may be infused with an anti-restenosis agent.

Abstract: A truss clamp for connection with a second clamp when installing truss assemblies includes a mechanism for adjustably connecting the two clamps in spaced relation. The truss clamp includes a fixed member and a rotatable member, the rotatable member having first and second ends and being pivotally connected to the fixed member intermediate the ends of the rotatable member and being rotatable between a first position wherein the first end is in confronting relation with a portion of the fixed member and a second position wherein the second end is in confronting relation with the portion of the fixed member. A holding mechanism may be disposed over a center spring action mechanism, for selectively maintaining the rotatable member in at least the second position. A method of installing trusses using a truss clamp is also disclosed.

Abstract: The present invention provides a cost effective means by which pressure reduction in a fluid flow control device is optimized. The pressure reduction achieved according to the present invention also minimizes valve wear and presents new solutions in reducing, attenuating, eliminating, damping, redirecting, or otherwise defeating valve noise. In accordance with one embodiment of the present invention, a flow control device is provided including a valve trim assembly comprising a plurality of valve trim disks defining a plurality of flow paths along a fluid passage between a fluid inlet and a fluid outlet of the flow control device. Respective flow paths defined by the valve trim disks comprise an expansion/contraction mechanism, a velocity control mechanism, an acoustic chamber, and frequency shifting passages. The expansion/contraction mechanism has a cross section including rapid increases and decreases in cross-sectional flow area.
