  • Drug-eluting stent
    Patent number: 7951193
    Abstract: 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.

  • Stent with Dynamic Drug Reservoirs
    Publication number: 20110066227
    Abstract: A stent having one or more beneficial agents which enhance the healing effect of the stent. The agent is positioned within a reservoir. The reservoir dynamically releases the agent when the stent is expanded. The reservoir makes use of various changes in stent shape during expansion to assure proper release of the agent. Agent release can be modulated at various points along the stent and with various rates of release. The reservoirs can also be cooperatively combined with features that enhance stent flexibility, structural integrity, and which prevent recoil.
