Circumferentially offset variable porosity devices

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 polymer, and
• a second circumferential portion circumferentially opposite the first circumferential portion, the second circumferential portion being free of the polymer coating,
• 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, and
• a second neck between the second bulb and the third bulb along the longitudinal axis.

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 longitudinal segment comprising:
• a first circumferential portion comprising a first braid angle, and
• a 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 second longitudinal segment,
• at least one of the first longitudinal segment and the second longitudinal segment comprising a bulb, and
• a lumen configured to allow perfusion of blood through the textile structure parallel to the longitudinal axis.
