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 the 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; a first end feature defining 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, 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 defines an expanded volume diameter (D e) and a surface that is substantially perpendicular to a central axis of the device, and wherein, in the expanded state, the tapered transition portion defines a first transition diameter (D 1) proximate the perpendicular surface of the expanded volume portion and a second transition diameter (D 2) proximate the proximal end of the first end feature, wherein the first transition diameter (D 1) is greater than the second transition diameter (D 2), is smaller than the expanded volume diameter (D e), and is disposed between the second transition diameter (D 2) and the expanded volume diameter (D e), and wherein the second transition diameter (D 2) is substantially equal to a diameter of the first end feature. a tubular structure comprising a plurality of braided strands, each braided strand comprising a proximal strand end and a distal strand end; a first end feature defining 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, 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 defines an expanded volume diameter (D e) and a surface that is substantially perpendicular to a central axis of the device, and wherein, in the expanded state, the tapered transition portion defines a first transition diameter (D 1) proximate the perpendicular surface of the expanded volume portion and a second transition diameter (D 2) proximate the proximal end of the first end feature, wherein the first transition diameter (D 1) is greater than the second transition diameter (D 2), is smaller than the expanded volume diameter (D e), and is disposed between the second transition diameter (D 2) and the expanded volume diameter (D e), and wherein the second transition diameter (D 2) is substantially equal to a diameter of the first end feature.
