A stent comprises at least one stent member woven to form a substantially
tubular body that defines a flow path. The tubular body comprises a first
region and a second region. In the first region the at least one stent
member defines a plurality of first region openings and in the second
region at least one first portion of the at least one member and at least
one second portion of the at least one member are engaged together to
form at least one primary strand. The at least one primary strand defines
a plurality of second region openings. The at least one of the plurality
of second region openings is in fluid communication with the flow path.
The plurality of second region openings provide the second region with a
greater porosity than the first region.
