“…Moreover, the length and flexibility of catheters and guidewires, as well as their limited number of degrees of freedom, may severely reduce the surgeon's visual and tactile perception when manipulating these tools during the treatment. Therefore, various catheter simulators using a computer have been developed to improve safety in endovascular treatments (Otani et al, 2015;Chiang et al, 2013;Irie et al, 2012;Hirayama et al, 2011;Schafer et al, 2007;Cai et al, 2006;Lenoir et al, 2006;Bhat et al, 2005;Konings et al, 2003;Yamamura et al, 2003;Dawson et al, 2000;Lawton et al, 2000;Wang et al, 1998;Barnes et al, 1997;Martin and Johnson, 1989). Many of them are physically-based numerical simulators, using multibody dynamics or finite element method (FEM).…”
