An example aneurysm implant can include a tubular braid that can have an open end, a pinched end, and a predetermined shape. In the predetermined shape, the tubular braid can have three segments and two inversions, one of the three segments extending between the two inversions and forming a sack. Two of the segments can form a substantially semispherical shape. The tubular braid can be implanted in an implanted shape based on the predetermined shape. The substantially semispherical shape of the tubular braid can aid in decreasing a pulsatile blood inflow rate and a pulsatile blood outflow rate for a substantially spherical aneurysm cavity.

This invention provides an aneurysm embolization auxiliary device, belonging to the field of medical device technology. The device includes a delivery catheter, an operating handle, a balloon, and a filling unit. The delivery catheter delivers a treatment device to the aneurysm location. The operating handle is located at the proximal end of the delivery catheter. The balloon, after inflation, supports the blood vessel.
