Connectable catheter

1. A connectable catheter system, comprising:

an intermediary catheter comprising an external section and a tip section, the tip section is configured to be inserted into a body of a subject;

a reconnectable indwelling stent comprising a connecting section and a target section, the target section being configured to be located within a body of the subject, and

a stylet removably insertable into the inner lumen of the intermediary catheter,

wherein the connecting section of the reconnectable indwelling stent is configured to reversibly connect, within the body of the subject, to the tip section of the intermediary catheter to form a continuous conduit between the intermediary catheter and the reconnectable indwelling stent, and

wherein the stylet comprises, at a tip section thereof, an attachment member configured to attach to the connecting section of the reconnectable indwelling stent, such that when the stylet is attached to the reconnectable indwelling stent and is proximally retracted within the inner lumen of the intermediary catheter, the reconnectable indwelling stent is pulled into the inner lumen of the intermediary catheter.

2. The connectable catheter system of claim 1 , wherein the connecting section of the reconnectable indwelling stent is configured to fit into an inner lumen of the tip section of the intermediary catheter; wherein the inner lumen of the intermediary catheter comprises a securing member configured to secure the connecting section of the reconnectable indwelling stent within the inner lumen of the tip section of the intermediary catheter; and wherein the securing member is further configured to seal a fluid passage between the outer wall of the reconnectable indwelling stent and the inner wall of the intermediary catheter.

3. The connectable catheter system of claim 2 , wherein the securing member comprises a deployable securing member, vacuum ducts, flexible plate, matching recesses in the connecting section of the reconnectable indwelling stent and the inner lumen of the tip section of the intermediary catheter, or any combination thereof.

4. The connectable catheter system of claim 2 , wherein the securing member comprises one or more inflatable balloons, configured to be inflated within the inner lumen of the intermediary catheter, and wherein the intermediary catheter further comprises an inflating port configured to inflate the one or more inflatable balloons.

5. The connectable catheter system of claim 1 , wherein the intermediary catheter further comprises a sealing member configured to seal a fluid passage between the outer wall of the reconnectable indwelling stent and the inner wall of the intermediary catheter.

6. The connectable catheter system of claim 1 , wherein the stylet's attachment member comprises a magnet configured to attract the connecting section of the reconnectable indwelling stent, and wherein the connecting section of the reconnectable indwelling stent comprises a magnet or a component attractable by the stylet's magnet.

7. The connectable catheter system of claim 1 , wherein the stylet further comprises or is functionally associated with an indication unit configured to provide an indication of a connection between the attachment member of the stylet and the connecting section of the reconnectable indwelling stent.

8. The connectable catheter system of claim 2 , wherein the reconnectable indwelling stent comprises a stopper element at an outer wall thereof, wherein the stopper element is located between the connecting section and the target section and wherein the stopper element is configured to limit the length of the reconnectable indwelling stent that can enter the inner lumen of the intermediary catheter.

9. The connectable catheter system of claim 1 , further comprising a guide rod removably insertable into the inner lumen of the connectable catheter, the guide rod is configured to facilitate the penetration of the tip section of the intermediary catheter into the subject's body and to remove the reconnectable indwelling stent from the intermediary catheter when pushed distally within the inner lumen of the connectable catheter.

10. The connectable catheter system of claim 1 , further comprises a circuitry unit configured to provide an indication when the continuous fluid conduit is formed.

11. The connectable catheter system of claim 1 , further comprises a vacuum source configured to create vacuum in the inner lumen of the intermediary catheter to secure the positioning of the reconnectable indwelling stent.
