The Dornier Cascade CAS60VR is a sterile, single-use ureteral stent designed to relieve ureteral obstruction due to stones, strictures, malignancy, trauma, or in conjunction with procedures like ESWL. The stent is constructed from a thermoplastic polyurethane elastomer, compounded with barium sulfate for radiopacity, and features a hydrophilic coating that is activated by fluid to reduce friction for easier, less traumatic insertion and removal. The CAS60VR model specifically refers to a 6 French (Fr) diameter stent with variable lengths (typically 22–32 cm).
- Key Features:
- Double Pigtail Design: Secures the stent in place at both renal and bladder ends to minimize migration.
- Hydrophilic Coating: Activated by fluid, this coating creates a smooth surface for easy passage through delicate ureteral tissue.
- Radiopaque: Barium sulfate compounding ensures clear visualization under fluoroscopy or X-ray.
- Graduation Marks: Facilitate accurate placement and positioning during insertion.
- Drainage Holes: Along the shaft and at both pigtail ends for optimal urine drainage.
- Monofilament Tether: Attached to the bladder end for easy repositioning and removal.
- One-Step Insertion System: Includes a pigtail straightener for simplified placement over a guidewire.
- Sterile, Single-Use: Labeled for a maximum 30-day indwell time.
- Available Sizes: 4.9–8.0 Fr diameters, lengths from 14–32 cm; CAS60VR is 6 Fr, variable length (typically 22–32 cm)
