Laparoscopic suturing is one of the most difficult and time-consuming tasks in laparoscopic surgery. The long instrument shafts, two-dimensional view, and limited space for movement make simple actions, such as grasping and manipulating the needle and thread, difficult in the laparoscopic setting. To simplify the suturing process, the Hornet...

Glioblastoma multiforme tumors (GBM) are the most frequent and aggressive brain tumor type and have a very low survival rate. In order to improve the patient’s outcome for a patient suffering from GBM the production of brain phantoms can be of great help. A brain phantom can be used for multiple purposes, such as neurological planning, training...

In up to 30% of hernia patients revision surgery is needed due to infection, pain and defect recurrence. The role that abdominal wall tension plays in this is incontrovertible: most repair techniques in herniorrhaphy aim to reduce tension at the aponeurotic edge, as excess tension is directly related with local ischemia and recurrence of the...

This thesis describes the design process of a new instrument that can be used to perform a fetal aortic valvuloplasty procedure. Congenital heart defects occur in 8 to 12 out of every 1000 live births. Aortic stenosis (AS) is one of the most common congenital heart defects. When AS occurs, the opening and closing of the aortic valve does not...
