- Internal inflatable silicone retention balloon
- Medical-grade silicone construction
- Proximal anti-reflux valve
- Tapered, recessed, trimmable distal tip
- Radiopaque stripe for imaging visibility
- Centimeter markings for external length verification
- Detachable extension sets so the button can be concealed when not in use
