摘要： Apparatus and methods for aspirating emboli from a vascular filter (30) or stent within a patient's circulatory system are provided. A filter sac (33) 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. Two families of aspiration devices are provided: a single catheter type and telescoping dual catheter type. The single catheter type uses one catheter both to aspirate emboli and retrieve a vascular filter. The telescoping dual catheter type device uses two catheters, with one catheter disposed inside the other, so that the inner catheter is used to aspirate emboli from a vascular filter and the outer catheter being used to retrieve the vascular filter. Aspiration through the catheters may be accomplished using a syringe coupled to the catheter via a hemostatic valve.

摘要： A stent includes first and second ends, a first set of cells disposed at the first end, a second set of cells disposed adjacent the first set of cells, and a plurality of connectors coupling the first set of cells with the second set of cells such that radial expansion of the second set of cells causes the first set of cells to flare radially outwardly. The stent is delivered within an ostium. For example, the stent is introduced into a main vessel in a contracted condition, and positioned such that a first portion of the stent is disposed adjacent an ostium communicating with a branch, and a second portion of the stent is disposed within the branch. The second portion of the stent is expanded within or adjacent the branch, causing the first portion of the stent to flare radially outwardly until the first portion engages the ostium.

摘要： Apparatus (10) for locating an ostium of a branch vessel includes a delivery- catheter (12) having a distal end (16) sized for introduction into the branch, and locator elements (50) including first ends (52) fixed to the distal end (16) and second ends (54) free from the distal end (16). The locator elements (50) are compressible from a transverse, deployed condition to an axial, contracted condition, wherein the second ends (54) are disposed proximal to the first ends (52). The catheter (12) may be used to deliver a stent (40) into the branch with the expanded locator element (50) facilitating positioning the stent (40).
