By using a guidewire fixator, the distal guidewire position can be secured in an artery. This new principle enables a method for fenestrated endovascular aortic repair where the connection between the aortic branches and the stent graft fenestrations is made before inserting and deploying the stent graft.
Methods
This is conducted using a fenestrated stent graft with preloaded catheters, through which the prepositioned and distally secured guidewires from the branches are inserted.
Results
This report covers the method when implementing a single fenestration stent graft in pig.
Conclusions
Successful tests with single and dual fenestrated grafts have been conducted in pigs.
