Onkos Surgical Receives FDA 510(k) Clearance for ELEOS Proximal Tibia with NanoCept Antibacterial Technology
核心洞察
Onkos Surgical (搜索) received FDA 510(k) clearance for its ELEOS Proximal Tibia (搜索) with NanoCept Antibacterial Technology (搜索), marking the first 510(k) clearance for NanoCept since its original De Novo authorization in April 2024.
The NanoCept technology demonstrated up to 99.999% bacterial kill rate in preclinical studies, offering a proactive approach against intraoperative bacterial contamination (搜索) in orthopaedic implants.
The ELEOS Proximal Tibia (搜索) with NanoCept is part of the company's limb salvage system designed for patients with significant bone loss (搜索) due to cancer (搜索), trauma, or previous surgical procedures.
Onkos Surgical (搜索) announced it has received 510(k) clearance from the U.S. Food and Drug Administration for its ELEOS Proximal Tibia (搜索) with NanoCept Antibacterial Technology (搜索). This regulatory milestone represents the first 510(k) clearance for the NanoCept Antibacterial Technology since the original De Novo authorization was granted in April 2024.
Breakthrough Antibacterial Technology
The NanoCept technology offers a proactive approach against intraoperative bacterial contamination (搜索), addressing a critical challenge in orthopaedic implant procedures. In preclinical studies supporting the original De Novo market authorization, NanoCept demonstrated up to a 99.999% (5-log reduction) kill rate of bacteria commonly found in operating room environments.
"The NanoCept Antibacterial Technology (搜索) is an important addition to comprehensive bacterial contamination (搜索) mitigation efforts in orthopaedic surgery," said Steven Gitelis, MD, Director of Musculoskeletal Oncology at Rush University Medical Center and Chief Medical Officer of Onkos Surgical (搜索). "The clearance of the ELEOS Proximal Tibia (搜索) with NanoCept Antibacterial Technology allows us to extend this technology to one of the most challenging anatomical sites for bone tumors (搜索) and complex bone loss (搜索)."
Clinical Applications and Market Adoption
The ELEOS Proximal Tibia (搜索) with NanoCept Antibacterial Technology (搜索) is part of Onkos Surgical (搜索)'s ELEOS Limb Salvage System, which provides comprehensive reconstruction options for patients with significant bone loss (搜索) due to cancer (搜索), trauma, or previous surgical procedures. The orthopaedic market has shown steadily increasing case demand for the NanoCept technology since the first case took place in December 2024.
More than 350 leading academic medical institutions in the United States currently choose Onkos for their complex revision and tumor orthopaedic cases. The company's portfolio includes innovations in antibacterial implant coatings, virtual surgical planning, 3D anatomic modeling and printing, implant design, and workflow optimization.
Strategic Expansion Plans
"This first post-De Novo 510(k) clearance marks a major milestone, highlighting our commitment and capability to advance NanoCept technology throughout the ELEOS implant system—and ultimately beyond," said Patrick Treacy, CEO and Co-founder of Onkos. "We remain dedicated to supporting the surgeons we serve and the patients they treat by delivering truly innovative and differentiated technologies."
The company notes that while preclinical studies have demonstrated the technology's antibacterial effectiveness, the NanoCept technology's effectiveness has not been shown in human clinical trials to prevent or reduce infection rates. This clearance positions Onkos to expand the NanoCept technology across additional implant systems in the future.
