Summary: Nester and Tornado embolization coils are used to occlude blood vessels in various interventional radiology procedures. They are primarily used by interventional radiologists to treat conditions like aneurysms and varicoceles.

FDA Clearance Information

Pathway 510K
Decision Date May 19, 2016
Product Code KRD
Device Class Class 2
Evidence 0 studies

The Nester and Tornado embolization coils by Cook were cleared via the FDA 510(k) pathway on May 19, 2016. They are classified as Class 2 medical devices.

What It Is

The Nester and Tornado embolization coils are small, flexible coils used to block blood flow in targeted blood vessels. These coils are inserted through a catheter and deployed in the vessel, where they expand and induce clot formation, effectively occluding the vessel. This process is used to treat conditions such as aneurysms, arteriovenous malformations, and other vascular abnormalities.

Clinical Applications

These embolization coils are commonly used in interventional radiology to manage vascular conditions. They are often employed in procedures to treat aneurysms, gastrointestinal bleeding, and varicoceles. The coils are used in both elective and emergency settings, and are suitable for a wide range of patient populations, including those with complex vascular anatomy.

Indications for Use

The FDA-cleared indications for these embolization coils include the occlusion of blood vessels to treat conditions like aneurysms and vascular malformations. They are used when it is necessary to block blood flow to a specific area to prevent bleeding or reduce blood supply to a lesion.

Practical Considerations

The coils come in various sizes to accommodate different vessel diameters and are compatible with standard catheter systems. Proper sizing and placement technique are crucial for effective occlusion and minimizing complications. Clinicians should be familiar with the catheterization techniques required for deploying these coils.

Related Literature

The linked study examined the use of real-world data to assess the safety and performance of embolization coils post-market. It highlighted the challenges of transforming electronic health records into real-world evidence due to the broad clinical use and long-term follow-up required for these devices. The study emphasized the importance of post-market surveillance in understanding device performance beyond pre-market clinical trials.
