What is TenJet?

TenJet is a device designed to target and treat the source of your chronic tendon pain. The needle-like device utilizes a controlled, high pressure stream of sterile saline to act as a  cutting blade and selectively remove diseased tendon while sparing healthy tissue. The device can be used in minimally invasive procedures, performed under a local anesthetic, in approximately fifteen-minutes, to treat the source of your chronic tendon pain.

Causes of Tendon Pain

Tendons are strong, flexible bands of connective tissue that connect muscle to bone, and transmit the energy needed to allow muscles and bones to create movement. Tendon injuries can result from activities that involve repetitive motion, and over time these injuries can generate micro-tears within the collagen fibers of the tendon. When a tendon is unable to heal, scar tissue can form which may cause pain and limit range in motion.

Tendonitis and tendinosis are different types of tendon injury, which require different treatment approaches. Tendonitis is a short-term inflammation of the tendon, which can resolve itself with rest and physical therapy. In contrast, tendinosis occurs when an overused tendon is injured or re-injured without receiving sufficient time to heal, which causes degeneration of the tendon fibers.
