Abstract
A medical device handle for articulation of a catheter includes a housing having a cylindrical shape, a control element at least partly encompassed by the housing, the control element having a pair of cross-cut threads cross-cut in opposing directions around a longitudinal axis of the medical device handle, and a pair of pull wire mounting elements each having a mounting thread engaging with one of the cross-cut threads. The control element is mechanically coupled to each of the pull wire mounting elements via the cross-cut threads and the mounting threads without any additional gear in between. A rotation of the control element around the longitudinal axis moves the pull wire mounting elements in opposite linear directions along the longitudinal axis.
