Development of an intraoperative crimper for self-expanding endografts
Endovascular stents (endografts) are used to repair aortic aneurisms within the blood vessel without open surgery. Self expanding endografts are composed of a Nitinol frame covered with a woven polyester material that is similar to the standard surgical grafts. For deployment, the grafts are loaded in so called catheters.
In some cases, the off-the-shelf endografts do not fulfill all the physicians’ needs and they remove the endograft from the catheter to make some manual adaptions. After that, the Endograft has to be loaded back into the catheter, for which there is no a standardized technique or device available. The goal of this project is to develop an intraoperative crimping system to allow fast and reliable crimping and loading of the endografts back into the catheter.
