Researchers at Columbia University, led by Dr. Stavros Thomopoulos, have developed a biomimetic device inspired by python teeth to improve rotator cuff repair. Rotator cuff injuries are common and can lead to shoulder pain and reduced mobility, affecting millions of people annually. The device nearly doubled repair strength in experiments and aims to securely reattach tendons to bone, reducing the risk of re-tearing post-surgery. The team utilized 3D printing and simulations to create a device that can grasp soft tissue without cutting through it, improving on current suturing techniques. Future efforts will focus on developing a bioabsorbable version for enhanced clinical use.
