Abstract: A catheter system for delivery of a ureteral catheter in a ureter includes a ureteral catheter, a pusher catheter to deliver the ureteral catheter at a desired location, and a connection device, to connect, in an assembled state a distal end of the pusher catheter to a proximal end of the ureteral catheter. The catheter further includes a releasable tether to secure a connection of the connection device between the ureteral catheter and the pusher catheter. The connection device includes a connector element provided on the ureteral catheter, and a sleeve provided on the pusher catheter, where the connector element is configured to be arranged in the sleeve, and that the tether is arranged to prevent unintentional release of the connector element out of the sleeve.

Abstract: The invention relates to a system for treating the ureter and/or the pyelo-ureter junction, comprising: a widener for widening a constriction, a guide for guiding the widener through the urethra, bladder and ureter, wherein the guide is introducible into the patient through the urethra, bladder and ureter to extend beyond pyelo-ureter junction, whereafter the widener is introducible along the guide and is subsequently able to be widened in order to widen the constriction whereafter the widener is removable.
