    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: Embodiments include, a medical device having a balloon portion with a first end, a second end, and a variable balloon mass to inflate the balloon portion non-uniformly from the first end to the second end. In one embodiment, the balloon portion inflates in a controlled manner to rupture a vulnerable plaque near the second end.

    摘要: A polymer coating for medical devices based on a polyolefin derivative. A variety of polymers are described to make coatings for medical devices, particularly, for drug delivery stents. The polymers include homo-, co-, and terpolymers having at least one olefin-derived unit and at least one unit derived from vinyl alcohol, allyl alcohol and derivatives thereof.
