Abstract
A method for making a braided medical device may involve positioning an insert inside a braided material, processing the braided material to form the braided medical device, dissolving and/or crushing the insert into multiple pieces, and removing the multiple pieces from the braided medical device. In some embodiments, the insert is made of gypsum. A braided medical device for occluding a defect in a heart may include a right disc for residing in a right side of the heart, a left disc having a partially circular shape for residing in a left side of the heart, and a waist extending between the right disc and the left disc and having a smaller diameter than that of either the right disc or the left disc.
Claims12
A method for making an implantable braided medical device, the method comprising:
- positioning a ring-shaped frangible insert inside a braided structure;
- processing the braided structure to form the implantable braided medical device;
- and
- removing the frangible insert from the braided medical device.
