Embodiments of the present disclosure are directed to medical devices for treating a target site. For example, a medical device (10) comprises a tubular member (11) having a proximal end (13) and a distal end (15), the tubular member having an expanded preset configuration when deployed at the target site and a reduced configuration for delivery to the target site. The tubular member comprises at least one layer of braided fabric, and the at least one layer of braided fabric comprises a plurality of first strands (12) having a first diameter and a plurality of second strands (14) having a second diameter. The first diameter is larger than the second diameter. The plurality of first strands and the plurality of second strands are intertwined to define regions of varying radial stiffness between the proximal and distal ends of the tubular member. |
