Tenon Medical develops the Catamaran® SI Joint Fusion System, which utilizes a single titanium implant and a less invasive inferior-posterior surgical approach to achieve sacroiliac joint fusion. This system addresses sacroiliac joint disruptions and degenerative sacroiliitis by providing significant pain reduction and functional improvement, as demonstrated by an 80% success rate in clinical outcomes.

Problem
Sacroiliac (SI) joint dysfunction, stemming from disruptions or degenerative sacroiliitis, leads to significant pain and functional limitations. Traditional SI joint fusion techniques can be invasive and may not always provide optimal long-term stability or pain relief.
Solution
Tenon Medical's Catamaran SI Joint Fusion System offers a less invasive inferior-posterior approach to SI joint fusion, utilizing a single, robust titanium implant to transfix the ilium and sacrum. The system is designed to facilitate authentic arthrodesis by providing direct access to the SI joint, optimizing implant placement in the dense cortical bone, and angling the trajectory away from critical neural and vascular structures. The Catamaran Fixation Device features two hollow fenestrated pontoons with an open framework, joined by a patented transfixing osteotome bridge, designed for packing with autologous bone to facilitate bony in-growth through the SI joint. Clinical studies demonstrate significant pain reduction, functional improvement, and high patient satisfaction with the Catamaran system.
Target Audience
The primary target audience includes orthopedic surgeons and neurosurgeons specializing in spine and SI joint disorders, as well as patients suffering from sacroiliac joint disruptions and degenerative sacroiliitis.
