## Intended Use

The AQ Hydrophilic Stent is used for temporary internal drainage from the ureteropelvic junction to the bladder.

## Device Story

AQ Hydrophilic Stent provides temporary internal drainage from ureteropelvic junction to bladder; utilizes hydrophilic coating to become 'slippery-when-wet' to reduce friction during placement; used by urologists in clinical settings; device facilitates urine flow; benefits patient by minimizing trauma during insertion and maintaining ureteral patency.

## Clinical Evidence

No clinical data provided; substantial equivalence established via bench-level comparison of materials, design, and intended use.

## Technological Characteristics

Materials: polyurethane, silicone, hydrophilic coating. Form factor: ureteral stent. Sterilization: standard procedures consistent with marketed Cook Urological devices.

## 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.

## Predicate Devices

- Slipcoat™ Stent (Cook Urological)
- Hydro-Plus™ (Microvasive)
