Abstract
Polymeric composite stents reinforced with fibers for implantation into a bodily lumen are disclosed.
Claims28
A method of making a stent comprising:
- forming a coating layer comprising a coating polymer over a tube-shaped fiber layer comprising a plurality of fibers, wherein the coating layer is formed by applying a fluid comprising the coating polymer dissolved in a solvent and by removing all or a majority of the solvent from the applied fluid, the fibers comprising a material being insoluble or having a relatively low solubility in the solvent, the material comprising a melting temperature greater than a melting temperature of the coating polymer;
- and
- fabricating a stent from the coated fiber layer.
A method of making a stent comprising:
- heating a fiber mesh tube comprising two types of fibers, a first fiber comprising a first polymer and the second fiber comprising a second polymer, the first polymer having a softening temperature lower than a softening temperature of the second polymer, wherein the tube is heated to a temperature range between the softening temperature of the first polymer and the softening temperature of the second polymer;
- and
- applying pressure to the tube so as to flatten at least some of the fibers of the tube to reduce a radial profile of the tube.
