A medical device having a proximal end and a distal end configured to self-expand from a contracted state when constrained within a delivery device toward an expanded state when deployed from the delivery device for delivery to a target site within a body lumen, the medical device comprising: a tubular structure comprising a plurality of braided strands , each braided strand comprising a proximal strand end and a distal strand end ; and a first end feature having a proximal end and a distal end , wherein the proximal end of the first end feature substantially coincides with the proximal end of the device and is configured to receive and secure the proximal strand ends via the proximal end of the first end feature , the proximal end of the first end feature comprising a proximal end surface , a distal end surface, and a circumferential surface extending between the proximal and distal end surfaces, wherein the tubular structure comprises: an expanded volume portion proximate to the first end feature and at the same end of the device as the first end feature; and a tapered transition portion extending between the expanded volume portion and the proximal end of the first end feature , wherein, in the expanded state, the expanded volume portion of the tubular structure is disk shaped and defines a surface that is substantially perpendicular to a central axis (A) of the device, and wherein, in the expanded state, the proximal strand ends are secured to the first end feature such that the transition portion substantially surrounds the circumferential surface of the first end feature and only the proximal end surface of the first end feature or a portion of the proximal end surface is exposed to fluid flow through the body lumen. a tubular structure comprising a plurality of braided strands , each braided strand comprising a proximal strand end and a distal strand end ; and a first end feature having a proximal end and a distal end , wherein the proximal end of the first end feature substantially coincides with the proximal end of the device and is configured to receive and secure the proximal strand ends via the proximal end of the first end feature , the proximal end of the first end feature comprising a proximal end surface , a distal end surface, and a circumferential surface extending between the proximal and distal end surfaces, wherein the tubular structure comprises: an expanded volume portion proximate to the first end feature and at the same end of the device as the first end feature; and a tapered transition portion extending between the expanded volume portion and the proximal end of the first end feature , wherein, in the expanded state, the expanded volume portion of the tubular structure is disk shaped and defines a surface that is substantially perpendicular to a central axis (A) of the device, and wherein, in the expanded state, the proximal strand ends are secured to the first end feature such that the transition portion substantially surrounds the circumferential surface of the first end feature and only the proximal end surface of the first end feature or a portion of the proximal end surface is exposed to fluid flow through the body lumen. <EOS>
