    摘要： A stent for delivering therapeutic agents to a body lumen includes a plurality of circumferential serpentine bands with each band comprising a plurality of struts. At least one strut has at least one first well region and at least one second well region. The at least one first well region has a first thickness, the at least one second well region has a second thickness, the first thickness being greater than the second thickness. Each well region defines a well having a depth. At least some of the wells contain a therapeutic agent.

    摘要： A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with a high metal to vessel ratio stent. A metal to vessel ratio of the high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the high metal to vessel ratio stent. The ingrowth of tissue provides secure fixation and sealing of the high metal to vessel ratio stent to the main vessel and remodels and essentially eliminates the aneurysm. Further, as the entire high metal to vessel ratio stent is permeably, the high metal to vessel ratio stent is deployed without having to rotationally position the high metal to vessel ratio stent.

    摘要： Nanocapsules are disclosed which comprise (a) a drug-containing core and (b) a polyelectrolyte multilayer encapsulating the drug-containing core. The nanocapsules include particles whose largest dimension typically ranges between 50 nm to 10000 nm. In some embodiments, the nanocapsules contain a single drug. In others, the nanocapsules contain multiple drugs, either within the same nanocapsules or within separate populations of nanocapsules. In some embodiments, the nanocapsules comprise surfaces that are functionalized, for example, with ligands that allow for attachment to bodily tissue. In some embodiments of the present invention, the nanocapsules are rendered magnetic or are rendered susceptible to magnetic fields. Also disclosed is a drug delivery method that comprises the steps of (a) providing nanocapsules such as those above; and (b) placing the nanocapsules at a desired location within the body of a subject using an implantable or insertable medical device.

    摘要： A stent comprises at least one curve deployment section. The at least one curve deployment section comprises at least one expansion ring having a circumferential length, a longitudinal length and comprising a first circumferential section and a second circumferential section. The first circumferential section comprises an expansion column and the second circumferential section comprises at least two expansion columns longitudinally offset from one another. The expansion column of the first circumferential section is engaged to the at least two expansion columns of the second circumferential section.
