    摘要: A stent includes a first flaring portion including first and second sets of cells that flare outwardly when the stent is expanded from a contracted to a flared condition, and a second main portion connected to the first flaring portion. During use, the stent is introduced into a main vessel in the contracted condition and positioned with the first portion adjacent an ostium. The first portion is flared, causing first struts of the first set of cells to move from an axial towards a radial and partial circumferential orientation and causing second struts of the second set of cells to move from an axial towards a radial orientation. The second portion resists expansion when the first portion is flared. The stent is expanded further such that the second portion expands within the branch body lumen, and the first and second struts move towards a more circumferential orientation.

    摘要: Apparatus and methods for aspirating emboli from a vascular filter or stent within a patient's circulatory system are provided. A filter sac of the vascular filter permits blood flow and captures emboli from the flow. The aspiration device removes emboli from within or proximal to the vascular filter or stent to reduce the risk to the ischemia during retrieval of the vascular filter and during a treatment procedure. Retrieval of the vascular filter may be accomplished using either the aspiration catheter or a separate retrieval catheter.
