Circumferentially offset variable porosity devices

摘要

An implantable device for treating a vascular cavity or vascular malformation may include a plurality of wires woven to form a textile structure expandable from a compressed state to an expanded state. The textile structure may have a longitudinal axis and may include, in the expanded state, a first longitudinal segment, a second longitudinal segment, and a lumen configured to allow perfusion of blood through the textile structure parallel to the longitudinal axis. The first longitudinal segment may include a first circumferential portion including a first braid angle and a second circumferential portion opposite the first circumferential portion and including a second braid angle greater than the first braid angle. At least one of the first longitudinal segment and the second longitudinal segment may comprise a bulb.

1. An implantable device for treating a vascular cavity or vascular malformation, the device comprising:
a plurality of wires woven to form a textile structure expandable from a compressed state to an expanded state, the textile structure having a longitudinal axis and comprising, in the expanded state:
a first bulb having a spherical shape,a second bulb having an elongate shape, the second bulb comprising:
a first circumferential portion comprising a first braid angle, anda second circumferential portion comprising a second braid angle greater than the first braid angle, the second circumferential portion circumferentially opposite the first circumferential portion,a third bulb having a spherical shape,the second bulb between the first bulb and the third bulb along the longitudinal axis,a first neck between the first bulb and the second bulb along the longitudinal axis, anda second neck between the second bulb and the third bulb along the longitudinal axis.
