Vascular implant

Abstract

A vascular implant comprises a structure defining a flow passage, the flow passage having a first end and a second end. The vascular implant is also provided with a skirt around at least a portion of the outer periphery of the structure. A portion of the skirt is fixed to the structure to form a seal with respect to the flow passage. The skirt is compliant such that, in response to a higher fluid pressure at one of the ends of the flow passage, the skirt is configured to be urged against the anatomy at the site in which the implant is located, to span between the outer periphery of the structure and said anatomy.
