Intended Use

Cydar EV provides image guidance by overlaying preoperative 3D vessel anatomy, from a previously acquired contrast-enhanced, diagnostic CT scan, onto live fluoroscopic images in order to assist in the positioning of guidewires, catheters and other endovascular devices. Cydar EV is intended to assist fluoroscopy-guided endovascular procedures in the lower thorax, abdomen and pelvis. Suitable procedures include (but are not limited to) endovascular aortic aneurysm repair (AAA and mid-distal TAA), angioplasty, stenting and embolization in the common iliac, proximal external iliac and proximal internal iliac arteries and corresponding veins. Cydar EV is not intended for use in the X-ray guided procedures in the liver, kidneys or pelvic organs.

Device Story

Cydar EV is a cloud-based SaaS platform providing augmented reality image guidance for endovascular surgery. It takes preoperative 3D CT scans and live fluoroscopic video feeds (via framegrabber) as input. The system performs automated 2D-3D registration by tracking vertebral anatomy, overlaying the 3D vessel model onto live X-ray images. Used in interventional suites by surgeons and clinicians, the output is displayed on a web browser, assisting in the precise positioning of guidewires and catheters. By providing real-time anatomical context, the device aims to improve procedural accuracy, reduce radiation exposure, and decrease contrast volume usage. The system is maintained by Cydar staff via secure cloud connections.

Clinical Evidence

Multi-center observational study evaluating safety, performance, and usability. Endpoints included registration accuracy, procedure time, radiation exposure, and contrast volume. Results supported clinical effectiveness, confirming the device provides accurate, robust, and usable image guidance for endovascular procedures.

Technological Characteristics

Software-only SaaS; cloud-hosted on Ubuntu Linux. Client-side runs on Windows 8.1 with Google Chrome. Connectivity via secure private/public network. Registration via machine vision tracking of vertebral anatomy. Complies with IEC 62304, IEC 62366-1, ISO 14971, and NEMA PS 3.1-3.20 (DICOM).

Indications for Use

Indicated for patients aged 18+ undergoing fluoroscopy-guided endovascular procedures in the lower thorax, abdomen, and pelvis, including AAA, TAA, angioplasty, stenting, and embolization. Contraindicated for procedures in the liver, kidneys, or pelvic organs.

Regulatory Classification

Identification
