Vascular implant and method for the production thereof

A method for producing a vascular implant, comprising the following steps:

• obtaining vessel parameters;
• creating a computer-aided model of a vascular implant based on the obtained vessel parameters, wherein the vascular implant comprises one or more modules, each comprising at least one tubular liner body;
• selecting one or more structural elements of a respective module from the group consisting of:
• one or more diameter changes along at least one tubular liner body, one or more bifurcations, one or more branches, one or more recesses, and one or more local reinforcements;
• determining parameters relating to the one or more selected structural elements;
• integrating the structural elements into the computer-aided model according to the determined parameters;
• producing the vascular implant on the basis of the created computer-aided model, wherein the vascular implant is textile and/or textile-based, and wherein the vascular implant is produced by warp knitting the vascular implant using a jacquard technique on the basis of the created computer-aided model;
• and
• placing and/or clamping the vascular implant onto a holder with a pre-stretch of at least 20% and thermoforming and/or heat setting the pre-stretched vascular implant.

• determining positions of at least one local reinforcement at the edges of the at least one recess;
• and
• incorporating at least one local reinforcement during the production of the vascular implant, wherein the local reinforcement comprises a change in stitch construction.
