TenJet, also known as percutaneous tenotomy, is a minimally invasive treatment for chronic tendon injuries and calcifications. TenJet’s minimally invasive technology allows physicians to provide patients with a rapid and precise option for removing chronic tendon pain without open surgery or lengthy and tedious treatment plans. The TenJet System bridges the gap in treatment options for tendinosis by enabling an image-guided, tissue selective resection of degenerative tendon tissue to target the source of chronic tendon pain and provide patients relief from tendinosis also referred to as chronic tendinitis or chronic tendinopathy.
The procedure is minimally invasive and performed using local anesthesia, requiring only a 1.65mm microincision, which reduces the risk of infection. TenJet’s innovative design utilizes a dual-lumen, 12-gauge needle to deliver a pressurized, high-velocity jet of saline that acts as a cutting water blade to resect and evacuate diseased tendinopathic tissue while leaving the surrounding healthy tissue unharmed.
TenJet enables physicians to treat calcifications, tendon thickening, and degeneration associated with tendinosis in an efficient yet precise manner, requiring only an outpatient setting to perform the procedure. During this less than 30-minute procedure, physicians can effectively remove only the diseased tissue and leave healthy tissue behind during real-time, image-guided procedures. Because an ultrasound-guided tenotomy using TenJet requires only a stab incision, the surgical site can be easily closed with Steri-Strips and in most cases, will not require sutures. Patients can expect minimal downtime and a gradual improvement in pain relief over a 3-month span.
