Inverting braided aneurysm treatment system having a semi-frustoconically-shaped portion

Abstract

The disclosed technology generally relates to braided implants for aneurysm therapy. The disclosed technology can include a system having a tubular braid comprising an open end, a pinched end, and a predetermined shape. In the predetermined shape, the tubular braid can include a first segment extending from the open end to a first inversion, a second segment extending from the first inversion to a second inversion and forming a bag comprising a semi-frustoconically-shaped portion proximate the first inversion such that the semi-frustoconically-shaped portion defines an inner channel forming an opening to the bag, and a third segment surrounded by the second segment and extending from the second inversion to the pinched end. The system can include a catheter having a lumen therethrough, a distal end, and an outer diameter at the distal end being sized to be inserted into the bag through the opening of the bag.
