Application device having a ureteral catheter and an introduction component for introducing the ureteral catheter, introduction component and application unit

An application device comprising:

• a ureteral stent, which comprises a ureteral stent main body and a receiving body connected to the ureteral stent main body by at least one elongated connection element of the ureteral stent,
• a pliable guide element on which the ureteral stent is positioned, and
• an introduction component configured for holding the ureteral stent and guiding the ureteral stent through a ureter of a patient along the pliable guide element,
• wherein the ureteral stent is displaceable along the pliable guide element in directions of movement opposite to each other by displacing the introduction component, and the introduction component is formed to guide the ureteral stent main body and the receiving body in displacing in the respective directions of movement,
• wherein the introduction component comprises a recess for introducing and holding the receiving body,
• wherein the introduction component comprises at least two pipe sections, into which the pliable guide element can be introduced, as well as at least one connection area connecting the at least two pipe sections to each other, wherein the at least two pipe sections and the at least one connection area delimit the recess, and
• wherein a first pipe section of the at least two pipe sections is formed as a proximal end of the introduction component, into which a distal main body end of the ureteral stent main body facing the receiving body is introduced at least in certain areas at least with the ureteral stent held on the introduction component.
