Abstract: An intragastric device includes an elongated member having a proximal end and a distal end and an anchor connected to the elongated member. The anchor includes a stem, a first arch and a second arch, and a curvilinear element. The stem includes a proximal end and a distal end. The distal end of the stem is attached to the proximal end of the elongated member. Each arch has first and second ends and a proximal peak therebetween. The first end of each arch is attached to the proximal end of the stem, and the second end of each arch extends radially away from the stem. The curvilinear element connects the second end of the first arch to the second end of the second arch.

Abstract: Fiber reinforced brittle matrix composites are disclosed with improved mechanical properties. The composites comprise extensible, somewhat elastic fibers and hardened brittle matrix materials. The fibers are positioned to support the composite in a three dimensional manner. Temporary tension forces are applied to some of the fibers before the matrix has completely hardened. The resulting three dimensional array of aligned fibers acts to improve the properties of the composite by providing self-compression. Self-compression is enabled by the alignment and stored elastic energy resulting from the temporary tension and from other deformations acting with the fiber network. The composites have improved response to challenges such as matrix shrinkage during hardening or bending forces and impacts. The invention is particularly useful with brittle, high modulus matrixes, such as cementitious materials and elastic fibers such as polymeric fibers.
