Abstract
The invention features is an embodiment of a drainage catheter to be used to drain fluid or gas from any body space with an improved distal tip of variable configuration, to facilitate passage of a guide wire used for catheter exchange. The invention also features an embodiment of a retention mechanism used to stabilize the drainage catheter in the body, where in this embodiment the retention mechanism is located outside of the lumen of the tube as it courses from its distal attachment sites to the catheter hub.
Claims6
A medical drainage catheter comprising:
- a hollow central lumen through a shaft of the drainage catheter,
- a hub end that is external to a body of a patient and can be attached to a fluid management system,
- a tapered distal tip end formed of a material, said distal tip end having a distal end hole with an original configuration and a second expanded configuration actuated by passage of a guide wire there through when blockage of the distal end hole is present, said guide wire having a diameter not greater than the diameter of the distal end hole in said original configuration.
A medical drainage catheter system comprising a drainage catheter, wherein the drainage catheter, after placement in an organ or cavity within the body of a patient, comprises a loop or another shape at its distal end that helps to retain the drainage catheter within the body, said loop or another shape being achieved by a retention apparatus that passes from the proximal end of the loop to a proximal end of the drainage catheter, said retention apparatus extending from within the organ or cavity to exterior of the body while residing exterior to any component of said drainage catheter system between the loop and the hub.
