Tahina Nephrostomy Balloon Dilator
The Tahina™ Nephrostomy Balloon Dilator creates the percutaneous nephrostomy access tract with high-pressure balloon dilatation. Designed for PCNL procedures, it enables safe and efficient one-step dilation with an integrated reinforced PTFE sheath for immediate tract access.
Key Features
- High-pressure balloon rated to 17ATM for reliable and efficient nephrostomy tract dilatation.
- Non-compliant balloon for precise, controlled diameter expansion without overexpansion.
- Integrated reinforced PTFE sheath for immediate nephrostomy tract access post-dilatation.
- Hydrophilic coating on the balloon and shaft for smooth, atraumatic insertion.
- Tapered tip with rounded end for atraumatic introduction into the nephrostomy tract.
- Radiopaque marker bands to confirm balloon placement under fluoroscopy.
- Delivery over standard 0.038" guidewires for secure, controlled percutaneous access.
- Available in 24Ch (8.0mm) and 30Ch (10.0mm) diameters for patient-specific PCNL sizing.

Frequently Asked Questions
What is the Tahina Nephrostomy Balloon Dilator used for? +
The Tahina Nephrostomy is a high-pressure (up to 17 ATM) balloon dilator designed to create the percutaneous renal access tract for PCNL in a single dilation step, with an integrated Amplatz sheath delivered over the balloon.
What balloon and sheath sizes are available? +
The balloon working length is 12 cm and the shaft is 55 cm. Compatible Amplatz sheath diameters and balloon dilation diameters are selected per case. See the specifications table for the full reference list.
How does the single-step dilation work? +
After percutaneous puncture and guidewire placement, the Tahina Nephrostomy balloon is advanced over the wire and inflated to dilate the tract. The Amplatz sheath is then advanced over the balloon into the renal pelvis without further coaxial dilation, reducing tract trauma and fluoroscopy time.
Is it compatible with both standard PCNL and mini-PCNL? +
Yes. The Tahina Nephrostomy is offered in size ranges suitable for both standard PCNL (24-30F tract) and smaller mini-PCNL tracts. Refer to the IFU for size-specific guidance.
Is it MDR-compliant? +
Yes. The Tahina Nephrostomy Balloon Dilator is CE-marked under EU MDR 2017/745 and manufactured under ISO 13485. It is supplied sterile for single use.
