The KERISMA is a single-use surgical instrument used to perform brachytherapy—a procedure that involves the implantation of radioactive seeds near a cancerous tumor. Designed and engineered by ION from the ground up, it features a disposable, pre-loaded cartridge that holds up to 150 radioactive seeds, ending the lengthy process of loading seeds individually. This seed applicator mechanically integrates all of the formerly manual and painstaking steps of brachytherapy, enabling the surgeon to automatically implant each seed with pinpoint precision in a single, error-free stroke. Just as important, the cartridge’s proprietary, sealed design prevents radiation leakage, making it much safer for the doctors who perform this procedure.
