Wu, Di (author), Zhang, Yao (author), Ourak, Mouloud (author), Niu, Kenan (author), Dankelman, J. (author), Vander Poorten, Emmanuel B. (author)Catheters are increasingly being used to tackle problems in the cardiovascular system. However, positioning precision of the catheter tip is negatively affected by hysteresis. To ensure tissue damage due to imprecise positioning is avoided, hysteresis is to be understood and compensated for. This work investigates the feasibility to model...journal article 2021

Robertson, P.D. (author), Gnanaraj, Jesudian (author), Wauben, L.S.G.L. (author), Huijs, Jan (author), Samuel, Vasanth Mark (author), Dankelman, J. (author), Horeman, T. (author)Background: Laparoscopy is a minimally-invasive surgical procedure that uses long slender instruments that require much smaller incisions than conventional surgery. This leads to faster recovery times, fewer post-surgical wound infections and shorter hospital stays. For these reasons, laparoscopy could be particularly advantageous to patients...journal article 2021

Minnaard, Jeffrey (author), Kleipool, Roeland P. (author), Baars, Wim (author), Dankelman, J. (author), Stufkens, Sjoerd (author), Horeman, T. (author)Aims: Resection of bone is performed in over 75% of all orthopaedic procedures and the electrically powered oscillating saw is commonly used to cut bone. Drawbacks are relatively large incisions and tissue damage due to overshooting often occur. Therefore, the goal of this study is to develop an improved bone-cutting system that has minimally...journal article 2021
