    摘要： An implantable medical device has an outer stent with a tubular body disposed about a longitudinal axis. The outer stent includes members defining openings which are in fluid communication with a flow path. At least one opening is larger than adjacent openings when the outer stent is in an expanded state, and is positioned between the ends of the outer stent. The at least one larger opening is a side branch opening having a perimeter. The device also has an inner stent with a tubular body disposed within the outer stent and about a longitudinal axis. The inner stent has a branch portion with deployable petals positioned adjacent to the side branch opening of the outer stent. The petals are biased against the perimeter of the side branch opening such that the petals are restrained from opening outward when the outer stent is in an unexpanded state.

    摘要： The embodiments described herein relate generally to medical devices that are useful for delivering one or more therapeutic agents to a body tissue of a subject, and methods for making and using such devices. In particular, the embodiments relate to a medical device such as a stent having a sidewall structure comprising a plurality of struts, in which one or more therapeutic agents are released from different surfaces of the struts at different release profiles. More particularly, the embodiments relate to a stent having a sidewall structure comprising a plurality of struts, in which the two side surfaces of each strut are coated with a coating composition that is different from the coating composition used to coat the outer surface and/or inner surface of the strut.
