Pectus Excavatum
Sternal Deformation
Haller index of 3.2 and higher
Mechanically Compressed Lung (atelectasis)
Cardiac Arrhythmias
Cardiac Compression
Mitral-/ tricuspid Valve Vices
Heart Murmurs and AV Conduction Delay
Psychological Stress due to the chest deformity
By combining specialised instrumentation with a dedicated fixation method, the system is designed to support established minimally invasive pectus repair approaches used in pediatric and adult patients.
Screw-based stabilisation mechanism designed to support plate placement
100% titanium construction including bars, screws and wires
Specialised plate holder designed for secure grip and smooth bar ends
Supports the minimally invasive Nuss Procedure
Designed to help reduce the risk of bar displacement
Biocompatibility – Designed for use in patients with known or suspected metal allergy
Designed to simplify surgical handling and enhance control
This procedure has shown improved patient well-being and long-term outcomes
