The System Is Comprised Of Magnet Devices And May Involve A Delivery System. Compression And Necrosis Of Tissue Between Magnet Devices Is Created By Polar Attraction Of The Magnet Devices With Healing Of Tissue Around The Devices. Once The Anastomosis Is Formed, The Magnet Devices Are Expelled Naturally. This Classification Does Not Include Devices Intended For Weight Loss Or Metabolic Disease Treatment
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most General & Plastic Surgery devices follow this clearance model.
