Captiva Spine WatchTower Spine Navigation System AI Enabling Technology
AI – Enabling Technology isn’t optional, it’s essential.

Today’s facilities demand enabling technologies that integrate seamlessly into existing workflows without driving up costs or requiring new infrastructure. The WatchTower Spine Navigation System was designed around this philosophy: simple setup, familiar imaging, and precise guidance without workflow disruption.

JUPITER, FL – November 2025 — In an era when technology is rapidly reshaping spine surgery and contributing to the standard of care in spine, navigation platforms still struggle to strike a balance between precision and practicality, especially in outpatient settings where cost, space, and radiation exposure are most critical. Captiva Spine® is addressing this challenge head-on with a series of advancements to its WatchTower® Spine Navigation System, aiming to make spine navigation more straightforward and accessible in the next generation of surgical environments.

Captiva Spine announced U.S. Food and Drug Administration (FDA) 510(k) clearance for new 21 cm and 31 cm Flat-Panel C-Arm Image Calibrators and AI-assisted 2D-to-3D image registration. For its WatchTower Spine Navigation System, these are advancements that further define the essential role of enabling technology.

The Challenge: Balancing Precision, Practicality, and Cost

For years, spine navigation has wrestled with trade-offs between precision and practicality. High-cost, CT-based systems deliver accuracy but introduce complexity, time, and radiation exposure, factors that can slow adoption and limit accessibility.

Today’s facilities demand enabling technologies that integrate seamlessly into existing workflows without driving up costs or requiring new infrastructure. The WatchTower Spine Navigation System was designed around this philosophy: simple setup, familiar imaging, and precise guidance without workflow disruption.
