摘要:
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.

Embodiments include an infusion-occlusion system having a delivery catheter, a guide catheter adapted to receive the delivery catheter, and a guidewire with an occlusion device adapted to be received within the guide catheter. The guide catheter of the catheter kit may be provided with an occlusion device at the distal end of the guide catheter. The delivery catheter may have an accessory lumen, coaxial and/or co-linear lumen, a supporting mandrel, and/or an occlusion device at its distal end. Moreover, according to embodiments, occlusion devices may be a single material or a composite balloon having an inner liner and an outer layer of different materials, a high compliance low pressure balloon, and/or a filter device that restricts particles from passing through but does not restrict fluid, such as blood. An inflation device with a large volume and low volume syringe can be used to inflate the balloon.

摘要:
The present invention provides a new and improved lead-free and cadmium-free glass enamel composition that displays good flow at traditional glass enamel firing temperatures and upon firing produces an enamel finish that displays no cracking, good chemical resistance, good weatherability, and improved color values. The glass enamel composition of the present invention includes a glass component, an oxidizer, a pigment system, and optional vehicles and fillers. The presence of the oxidizer in the composition, which can be included as part of the glass component, as a separately added material, or both, improves the color values of the fired enamel as compared to enamels formed using similar glass enamel compositions having no oxidizer present.
