    摘要： A stent assembly has a first stent body and a second stent body. The first stent body defines a first lumen having a first longitudinal axis therethrough, and the second stent body defines a second lumen having a second longitudinal axis therethrough. An end of the second stent body is hingedly engaged to a portion of the first stent body, and the first lumen and the second lumen are in fluid communication with one another. The stent assembly has a undeployed and a deployed state. In the undeployed state the first longitudinal axis and the second longitudinal axis are substantially parallel to one another and the second lumen is positioned entirely within the first lumen. In the deployed state the second longitudinal axis forms an oblique angle with the first longitudinal axis.

    摘要： According to an aspect of the invention, medical devices are provided which contain at least one polymeric region. The polymeric region contains at least one copolymer, which includes at least one high Tg vinyl aromatic monomer and at least one low Tg monomer. Moreover, the polymeric region contains at least one surface sub-region that is crosslinked and at least one bulk sub-region that is substantially non-crosslinked. According to another aspect of the invention, a method is provided which includes exposing a polymeric region of a medical device to energetic species such that at least one surface sub-region of the polymeric region becomes crosslinked and at least one bulk sub-region remains substantially non-crosslinked. The polymeric region contains at least one copolymer, which includes at least one high Tg vinyl aromatic monomer and at least one low Tg monomer.
