## TL;DR

ZAP Surgical makes ZAP-X, a self-shielded radiosurgery machine that aims beams from thousands of angles at brain tumours, treating brain metastases and meningiomas in one to five outpatient sessions without the concrete bunker or cobalt-60 source that older systems need. It is cleared in the US, Japan and Europe, with installations including Gustave Roussy.

## Summary

ZAP Surgical Systems, founded by Stanford neurosurgeon John R. Adler, makes the ZAP-X Gyroscopic Radiosurgery platform for dedicated cranial stereotactic radiosurgery (SRS). A linear accelerator on dual independent gantries delivers non-coplanar beams from thousands of angles with integrated kV imaging. The self-shielded design needs no radiation vault and, unlike Gamma Knife, no cobalt-60 source, lowering cost and allowing installation in outpatient settings. Indications include brain metastases, meningiomas and trigeminal neuralgia, treated in one to five sessions. ZAP-X received FDA 510(k) clearance in 2017, Japan Shonin clearance in 2020 and CE marking in 2021; the ZAP-Axon planning system is also FDA and CE cleared. Installations include Gustave Roussy, Haaglanden Medical Center, several German hospitals and eight systems in China. In November 2024 the company closed a USD 78 million Series E led by Qingdao Baheal Medical.
