Hybrid intravascular stent

A hybrid stent is formed which exhibits both high flexibility and high radial strength. The expandable hybrid stent for implantation in a body lumen, such as a coronary artery, consists of radially expandable cylindrical rings generally aligned on a common longitudinal axis and interconnected by one or more links. In one embodiment, a dip-coated covered stent is formed by encapsulating cylindrical rings within a polymer material. In other embodiments, at least some of the rings and links are formed of a polymer material which provides longitudinal and flexural flexibility to the stent. These polymer rings and links are alternated with metallic rings and links in various configurations to attain sufficient column strength along with the requisite flexibility in holding open the target site within the body lumen. Alternatively, a laminated, linkless hybrid stent is formed by encapsulating cylindrical rings within a polymer tube.

Multi-layered core golf ball

The present invention is directed towards a multi-layered core golf ball that comprises a center, a cover and at least two core layers formed around the center to create an inner ball, wherein the outermost core layer is relatively stiff and hard relative to the center. One outermost core layer is heavily filled with a density increasing material and at least one core layer functions as a moisture vapor barrier. One core layer may serve to provide all the functions in a single layer.

Multi-piece solid golf ball

In a multi-piece solid golf ball comprising a solid core consisting of a center core and an outer core, an inner cover layer and an outer cover layer, the solid core is molded from a rubber composition comprising a base rubber composed of (a) a polybutadiene having a high cis-1,4 content, a minimal 1,2 vinyl content and a viscosity η of up to 600 mPa·s at 25° C. as a 5 wt % toluene solution, being synthesized using a rare-earth catalyst, in combination with (b) another diene rubber, (c) an unsaturated carboxylic acid, (d) an organosulfur compound, (e) an inorganic filler, and (f) an organic peroxide; and the center core has a specific JIS-C hardness on its center and a specific JIS-C hardness on its surface and the certain difference, the outer core is harder than the surface hardness of the center core, the cross-sectional hardness of 1 mm outside from the border between the center core and the outer core is a specific range on JIS-C hardness, the surface of the outer core has a specific JIS-C hardness, the inner cover layer has a specific Shore D hardness; the outer cover layer has a specific Shore D hardness; and the outer cover layer has a lower Shore D hardness than the inner cover layer. This combination of features gives the ball a good, soft feel upon impact and an excellent spin performance that provides increased distance.
