In principal all known conventional satellite navigation systems like GPS, Galileo, GLONASS, QZSS and BeiDou are enabling the determination of the position with accuracy on the centimeter-level by help of the carrier phase. However, the carrier signals, upon which the navigation signals are modulated, are typically impaired by various error sources, like ionospheric errors, tropospheric errors, instrumental errors and/or other error sources, leading to a defective determination of the position. The invention enables a precise and reliable relative positioning (relative kinematic positioning – RTK) with centimeter-level accuracy in urban environments as well as a precise attitude determination (heading estimation with 0.25°/m accuracy) with low-cost sensors. Wit the new method the above mentioned errors can be
eliminated reliably.
The present invention provides a stent remover for open surgery which can be used to safely remove a stent without causing tissue damage. In a first step, at least three wires are threaded through the mesh of one end of the stent. Then, all wire ends are fed through a sleeve and fixed with a crimping device. Afterwards, the wires in the sleeve can easily be introduced into the funnel-shaped tube of the stent remover. By operating the turning knob of the device, a uniform and controllable pulling force is exerted to the wires. In this way, the stent constricts evenly and can easily be removed without serious tissue damage. In addition, stent removal with this novel device shortens the operation time, thereby reducing the potential for unforeseen complications. On behalf of RWTH Aachen University, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development.
