    摘要: A method of producing a stent-balloon assembly is disclosed which includes providing a stent having a polymeric component; exposing the stent to a relative humidity of 20% to 100%; and crimping the stent on a balloon of a catheter assembly. The polymeric component could be at least part of the material from which the stent is made or could be a constituent of a coating for the stent, such as a drug delivery coating. In lieu of or in addition to the application of humidity, a plasticizing agent can be applied to the polymeric component. A crimping device is also disclosed which allows the stent to be exposed to humidity during the crimping process.

    摘要: Provided herein is a poly(ester amide) (PEA) polymer blend and a polymeric coating containing the PEA polymer blend. The PEA polymer blend has a Tg above the Tg of poly(ester amide benzyl ester) (PEA-Bz) or the Tg of poly(ester amide TEMPO). The PEA polymer blend can form a coating on an implantable device, one example of which is a stent. The coating can optionally include a biobeneficial material and/or optionally with a bioactive agent. The implantable device can be used to treat or prevent a disorder such as one of atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.

    摘要: A system, nozzle assembly, and method for coating a stent with a solvent and polymer are provided. The polymer can include a therapeutic substance or a drug. The polymer and solvent can be discharged from separate tubes disposed within another tube carrying moving air. The polymer and the solvent mix together when they are discharged and are atomized by the air. The ends of the tubes can be concentric with each other. The ends of the tubes can also be positioned relative to each other to prevent accumulation of polymer at the ends of the tubes.

    摘要: A drug-eluting stent delivery system for the treatment of edge restenosis in a blood vessel. The drug-eluting stent delivery system has a balloon disposed about at least a portion of a catheter, the balloon having a first end and a second end and a working length therebetween, the first end and the second end each including a tapered portion, each tapered portion being attached to the catheter, the balloon being inflatable from a collapsed configuration to an inflated configuration. A drug-eluting stent contacts a wall of the blood vessel to maintain the patency of the vessel. The drug-eluting stent has a first end and a second end, the first end and the second end each including a tapered portion, wherein the drug-eluting stent is disposed over the balloon such that at least a portion of the first end and the second end of the balloon are covered by the tapered drug-eluting stent. A method for making the same is also disclosed herein.
