Artificial Urinary Diversion System - Kinematic requirements on fixation

Abstract

A German research group develops a new artificial urinary bladder - the Artificial Urinary Diversion System - to treat patients after excision of the human bladder suffering from end-stage bladder disease. The research project implies the development of a feasible fixation element guaranteeing a determined position of the implanted artificial organ in the abdomen of the patient. Hence it is crucial to define the kinematic requirements on the fixation considering the possible anatomical locations for fixating an artificial bladder with a special technical means. The Promontory of sacrum and the symphysis pubica are both possible anatomical locations. Due to this, the kinematic requirements on the fixation element are based on the range of motion of the human spine as well as the interaction between the implanted artificial bladder and adjacent human organs. The kinematic requirements can be considered as basis in the development process of the fixation for the Artificial Urinary Diversion System. © 2009 Springer-Verlag.
