Patent ID: 8758389

Claim:
A medical device 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; and a first end feature defining a proximal end and a distal end, wherein the first end feature 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 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, and wherein, in the expanded state, the tapered transition portion defines a first transition diameter proximate the expanded volume portion and a second transition diameter proximate the proximal end of the first end feature, wherein the first transition diameter is greater than the second transition diameter, is smaller than the expanded volume diameter, and is disposed between the second transition diameter and the expanded volume diameter, and wherein the second transition diameter is substantially equal to a diameter of the first end feature.
