Abstract Purpose: The in situ fenestration of a standard endograft is currently limited by difficulties in targeting the fenestration site under fluoroscopic control and by the lack of a safe method to perforate the graft. Evidence in the literature suggests the use of a 3 D electromagnetic navigator to accurately guide the endovascular instruments to the target and a laser to selectively perforate the graft. The aim of this work is to provide design guidelines to develop a sensorized catheter… 
Novel EM Guided Endovascular Instrumentation for In Situ Endograft Fenestration
Preliminary in vitro trials demonstrate the feasibility of the proposed instrumentation which could widespread the procedure for in situ fenestration and has the potential to expand indications for standard endovascular aneurysm repair to cases of acute syndromes.

Ex vivo efficacy demonstration of a laser fenestration system for endovascular abdominal aortic aneurysm repair (EVAR)
An ex-vivo study providing the harmlessness of laser irradiation effects on biological tissue surrounding the endograft wall is reported, suggesting that the diode laser can be safely used for the proposed surgical application.
In situ diode laser fenestration: An ex‐vivo evaluation of irradiation effects on human aortic tissue
A three‐dimensional navigation system for the accurate targeting of the fenestration site is described and results of an ex vivo study suggest that the diode laser can be safely used for the proposed surgical application.
Software Framework for VR-Enabled Transcatheter Valve Implantation in Unity
This work proposes an EM navigation platform, with software functionalities, developed using the Unity game engine, to mimic physical behaviors of surgical instruments inside the patient vasculature, handle the interaction between the tools and the anatomical model via collision detection, and deform in real-time the anatomy.

In Situ Laser Fenestration for Revascularization of the Left Subclavian Artery During Emergent Thoracic Endovascular Aortic Repair
In situ retrograde laser fenestration is a feasible and effective option for revascularizing the left subclavian artery (LSA) during emergent TEVAR as an alternative to debranching.
Current status of percutaneous endografting.
The experience with the off-label application of suture-mediated devices for percutaneous closure of arterial access sites during endovascular aneurysm repair, and a review of the literature on this topic are provided.
Buckling test as a new approach to testing flexural rigidities of angiographic catheters.
A new testing approach is proposed to clearly identify the flexural rigidity of catheters by using a buckling test to evaluate the peak compressive load and it was found that the Buckling test works very well and provides repeatable results.
