VASCULAR DEVICE FOR ANEURYSM TREATMENT AND PROVIDING BLOOD FLOW INTO A PERFORATOR VESSEL
First Claim
1. A method, comprising:
- positioning, at a target location within a blood vessel, a vascular device having a body in a first, collapsed configuration with the body comprising braided strands forming pores and apertures between the strands, the pores and the apertures being substantially the same size as each other in the first, collapsed configuration; and
expanding the body from the first, collapsed configuration to a second, expanded configuration with the apertures being disposed at a longitudinally central section of the body, the pores being disposed at longitudinally proximal and distal sections of the body, and the pores being generally uniform in size and smaller in size than the apertures in the second, expanded configuration;
wherein a number of strands in each of the proximal, central, and distal sections of the body is the same.

Abstract
A vascular device includes a body having a first, collapsed configuration and a second, expanded configuration. The body includes a plurality of heat-set strands that are braided such that when the body is in the second configuration, the strands form a plurality of pores and one or more apertures between the strands. The apertures are generally disposed at a longitudinal center region of the body. When the body is in the second configuration, the pores at proximal and distal portions of the body are generally uniform in size and smaller in size than the apertures. The pores and the apertures are substantially the same size when the body is in the first configuration.
