NDR Medical Technology Wins FDA 510(k) Clearance for its ANT-X Automated Robotic Device


NDR Medical Technology has announced that the ANT-X has been granted FDA 510(k) clearance by the U.S. Food and Drug Administration (FDA). This clearance makes ANT-X the world’s first automated robotic device to aid in needle positioning and alignment to access the kidney for Percutaneous Nephrolithotomy (PCNL), a urology procedure for kidney stone removal. It is designed to empower clinicians to perform image-guided Fluoroscopic percutaneous access with speed and precision.

Improving treatment outcomes for patients with kidney stones

Approximately 10 percent of the American population is affected by kidney stones in their lifetime (1), and there is a pressing need for effective treatment. Among treatment options available for patients, PCNL stands out as the preferred treatment of choice for patients (2), as it tends to see higher stonefree rates compared with procedures such as ureteroscopy (3). Despite its benefits, PCNL represents only an estimated 7-8 percent of stone procedures conducted in the US today (4). With FDA approval secured for the ANT-X, clinicians will be able to carry out PCNL procedures safely and effectively for a larger number of patients.

“As urologists, we recognise that achieving percutaneous access to the renal collecting system is a crucial step that significantly impacts the success of kidney stone surgery,” said Dr Kazumi Taguchi, Assistant Professor and head of research of Nephro-urology at Nagoya City University, “Despite advancements in surgical techniques, we are still faced with the daunting task of performing this procedure, which demands considerable time and effort.”

Increased market size in the US

With the advancement of PCNL techniques such as mini PCNL and ultra-mini PCNL, more patients can be discharged on the same day without the need for stents, tubing, or any remaining stones (5). “Recent trends show an increase in the use of PCNL targeting stones up to 2cm, while Mini PCNL has been proven to minimise adverse events. We are confident that the adoption of ANT-X reduces the complexity of such procedures.” said Alan Goh, CEO, NDR Medical Technology.

In the US, current reimbursement codes cover procedures for stone sizes up to 2cm or larger, with new updates to the codes allowing urologists to be incentivised for performing their own access in PCNL procedures(6). With ANT-X, urologists can now confidently perform image-guided access, which was previously challenging without assistance.

NDR Medical Technology also recently placed second in the MedTech category at SelectUSA Tech 2021, a showcase for entrepreneurs at the SelectUSA Investment Summit 2021, organised by the US Department of Commerce.

Unlocking new possibilities in the future of healthcare

Beyond urology procedures, the versatility of ANT-X extends to other indications. In Singapore, the company successfully conducted its first Neurospine procedure, discoplasty, in June 2023. Driven by a vision to revolutionise the standard of care, NDR Medical Technology is seeking partners and investors to join in the mission of creating breakthrough solutions that transform the future of healthcare.

“Achieving FDA 510(k) approval gives NDR Medical Technology access to the largest healthcare market in the world, and is a critical step ahead for the company,” said Hsien-Hui Tong, Executive Director – Investments, SGInnovate. “This milestone is a sign of consistent good traction made by the team as it continues to expand the applications of its technology, and deliver value to its customers, partners and investors.”
