Fenestration template for endovascular repair of aortic aneurysms

A computer-implemented method for generating a patient-specific fenestration template, comprising:

• receiving imaging data of a patient;
• generating, based at least in part on the imaging data, a 3-D digital model of an aorta lumen of a patient, the aorta lumen encompassing one or more branch vessels;
• causing generation of the fenestration template based at least in part on the 3-D digital model, wherein the fenestration template represents a model of the aorta lumen without an aneurysm, wherein the fenestration template is cylindrical, wherein a diameter of the fenestration template matches a diameter of the aorta lumen, and wherein generating the fenestration template comprises:
• detecting boundaries for the one or more branch vessels using the imaging data,
• adding indications of the one or more branch vessels to the 3-D digital model, and
• subtracting a cylinder with a desired fenestration diameter from a solid part of the fenestration template to create one or more openings in the fenestration template;
• and
• scaling up the fenestration template such that a minimum diameter of the fenestration template matches a graft diameter.
