Abstract: An all-purpose drainage catheter which includes an all-purpose drainage catheter lumen, an extension tubing, a collection bag, a catheter hub, a Luer valve. The extension tubing inserted into the all-purpose drainage catheter lumen. The collection bag is fluidly coupled to the extension tubing. The Luer valve facilitates nephrostomy care so that when the all-purpose drainage catheter is in place urine flows from the renal pelvis into the all-purpose drainage catheter lumen, the extension tubing and the collection bag. The Luer valve employs a scalloped Luer-style male connector which, when screwed into the catheter hub, further allows urine to flow from the renal pelvis into the all-purpose drainage catheter lumen, the extension tubing and the collection bag. The all-purpose drainage catheter includes an outer catheter hub, an inner catheter hub coupled to the Luer valve at one end thereof and insertedly coupled to the outer catheter hub.

Abstract: A percutaneous nephrostomy catheter system includes a nephrostomy catheter lumen, an extension tubing and a collection bag. The extension tubing is inserted into the nephrostomy catheter lumen. The collection bag is fluidly coupled to the extension tubing. A percutaneous nephrostomy catheter system also includes a catheter hub which employs a Luer valve in order to facilitate nephrostomy care so that when the percutaneous nephrostomy system is in place urine flows from the renal pelvis into the nephrostomy catheter lumen, the extension tubing and the collection bag. The Luer valve employs a scalloped Luer-style male connector which, when screwed into the catheter hub allows flow.
