1. A method of treating a cerebral aneurysm, comprising:
a. positioning an expandable member in a cerebral blood vessel at a location of a cerebral aneurysm, said expandable member comprising:
i. a braided mesh structure comprising a first distal end and a first proximal end; said braided mesh structure further comprises a plurality of wires arranged to define at least one first wall portion in which openings defined between said wires are small enough to interfere with inner content within said cerebral aneurysm from exiting said cerebral aneurysm;
ii. a push/pull wire comprising a second distal end and a second proximal end; said second distal end of said push/pull wire being connected to said first distal end of said braided mesh structure; said push/pull wire configured to expand said expandable member from a collapsed configuration to an expanded configuration when said second proximal end of said push/pull wire is actuated;
b. actuating said second proximal end of said push/pull wire thereby expanding said expandable member to engage the blood vessel walls;
c. further actuating said second proximal end of said push/pull wire thereby further expanding said expandable member for causing at least part of said expandable member to slightly protrude into a neck of said cerebral aneurysm;
d. allowing said first wall portion to interfere with inner content of said cerebral aneurysm exiting said cerebral aneurysm; and
e. actuating said second proximal end of said push/pull wire thereby contracting said expandable member;
f. removing said expandable member.
