Methods for making braid-ball occlusion devices
First Claim
Patent Images
1. A method of making an embolic device, the method comprising:
- collapsing a midsection of a tubular braid to a substantially closed configuration using a tie;
inverting a first tubular section of the tubular braid over the tie at the midsection to produce dual layers in the braid such that the braid has a tubular configuration with a closed end at the midsection and an open end opposite the midsection;
while holding the midsection substantially closed, inserting a form into the open end to position the dual layers of the braid around the form;
setting a device body shape; and
removing the tie and the form from the braid, the form being removed in one piece.

Abstract
Embolic implants, delivery systems and methods of manufacture and delivery are disclosed. The devices can be used for aneurysm treatment and/or parent vessel occlusion. Implant designs offer low profile compressibility for delivery to neurovasculature, while maintaining other necessary features such as density for occlusion purposes and desirable radial strength characteristics.

14. A method of making an embolic device, the method comprising:
-
constraining a midsection of a tubular braid in a substantially closed configuration; inverting a first tubular section of the tubular braid over the midsection to produce a dual layer tubular section having a closed end, at the midsection and an open end opposite the closed end; inserting a form within the dual layer section through the open end such that the form is positioned axially between the folded edge and the open end of the folded section; and setting a device body shape based on the form; and after setting the device body shape, removing the form in one piece from the braid. - View Dependent Claims (15, 16, 17, 18, 19, 20)
