Journal ArticleDOI
Challenges and perspectives in brain tissue testing and modeling
TL;DR: Key characteristics of brain tissue behavior on different length and time scales are summarized and proposed application‐specific modeling approaches, which are as complex as necessary but as simple as possible are proposed.
Journal ArticleDOI
Very large and giant microsurgical bifurcation aneurysms in rabbits: Proof of feasibility and comparability using computational fluid dynamics and biomechanical testing.

TL;DR: The proposed model showed favorable aneurysm patency rates, low morbidity and good hemodynamic comparability with complex flow patterns, and biomechanical testing suggests that experimentalAneurysms might be even more fragile compared to human aneurYSms.
Proceedings Article
Experimental study and numerical analysis of arterial clamping
TL;DR: In this paper, a finite element simulation of arterial clamping is used to determine the risk of tissue damage. But the simulation is limited to a single vessel and cannot be applied to other vessels.
Characterizing the mechanical response of soft human tissue for medical applications
TL;DR: The inverse problem is solved in order to determine the parameter of constitutive equations that account for viscoelastic or viscoplastic tissue response at large deformations.
