## Intended Use

The ureteral double loop stent are intended for drainage of the upper urinary tract where indicated such as in the case of ureteral obstruction, fistula, calculus debris/fragmentation, tumor, etc. The "flush" ureteric configuration with certain models (reference numbers) is intended to flush the lithiasis to the kidney before ESWL.

## Device Story

VORTEK and BIOSOFT ureteral double loop stents are passive medical devices designed for upper urinary tract drainage. Stents are inserted by urologists to bypass obstructions, manage fistulas, or facilitate drainage following calculus fragmentation. The device functions as a conduit to maintain ureteral patency. The 'flush' configuration allows for irrigation to reposition lithiasis prior to extracorporeal shock wave lithotripsy (ESWL). These devices are used in clinical or surgical settings. They provide mechanical relief of obstruction and support patient recovery by preventing hydronephrosis and associated complications.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Ureteral double loop stents; VORTEK and BIOSOFT material variants; passive drainage design; intended for temporary indwelling use.

## Regulatory Identification

A ureteral stent is a tube-like implanted device that is inserted into the ureter to provide ureteral rigidity and allow the passage of urine. The device may have finger-like protrusions or hooked ends to keep the tube in place. It is used in the treatment of ureteral injuries and ureteral obstruction.
