TenJet™ – Revolutionizing Minimally Invasive Tenotomy

TenJet is a specialized needle-like device designed for the minimally invasive treatment of tendinosis or chronic tendinitis, offering relief from persistent tendon pain. The device utilizes a pressurized, high-velocity jet of saline to precisely resect and eliminate diseased tendon tissue while preserving healthy tissue.

TenJet is employed by physicians to address chronic tendon pain associated with conditions like Tennis Elbow, Golfers’ Elbow, Jumper’s knee, Achilles tendinosis, and tendon calcifications in various areas such as the shoulder, elbow, hamstring, hip, and even plantar fasciitis.

The procedure involves a small incision and is conducted in an outpatient setting. Real-time ultrasound imaging is employed to visualize the affected tissue, ensuring targeted and precise intervention. TenJet aims to achieve the removal of diseased tendon tissue, akin to the goals of open or arthroscopic surgery, but with the advantages of a less invasive approach.

Cutting-Edge Hydrodynamics

TenJet™ stands as a technological marvel, leveraging high-pressure saline as a precise resection tool. Featuring state-of-the-art two-lumen devices, this system operates with unprecedented precision, utilizing pressures of up to 14,000 psi to masterfully cut tissues. The Venturi effect suction is the final touch, ensuring the immediate removal of targeted tissue and providing patients with a comprehensive and minimally invasive solution.

Key Technological Features


TenJet™ lies a meticulously designed 12-gauge, 3-inch, 2-lumen needle, allowing for a targeted and minimally invasive procedure. Guided by ultrasound, this approach ensures pinpoint accuracy, and all of this is achieved through a small incision for device access. Patient comfort takes precedence, with the procedure conducted under local anesthetic.

Operational Mechanism

The intricacies of the TenJet™ system are orchestrated by a high-pressure pump that delivers sterile saline to the handpiece. Saline is propelled as a fine jet with remarkable force, reaching pressures up to 14,000 psi. The needle tip is designed to gently pull in soft, diseased tissue without causing harm to the surrounding healthy tendon tissue, ensuring a delicate and effective procedure.

Frequently Asked Questions (FAQ)

What is the Tenjet Procedure like?

The TenJet procedure is a minimally invasive treatment for conditions like tendinosis. TenJet is a needle-like device that enables minimally invasive treatment by selectively removing degenerative tendon tissue, sparing healthy tissue. The TenJet system identifies and removes damaged calcified tendon tissue using a non-thermal stream of pressurized saline, acting like a blade for the diseased tissue. The procedure is termed a tenotomy, involving the surgical removal of damaged tissue, but with TenJet, it’s a more minimally invasive approach.

Will I experience discomfort during the procedure?

At the beginning of the treatment, you may encounter some sensations of discomfort when the physician administers a local anesthetic. Following the procedure, there might be soreness in the treated area as the effects of the anesthetic diminish.

What is the expected duration of my recovery?

Typically, noticeable improvements in tendon pain may begin as early as two weeks post-procedure, with substantial relief within three months for chronic tendinitis or tendinosis. Your physician will outline a personalized post-treatment recovery plan, involving elements such as physical therapy and/or home exercises. The timeline for complete symptom relief can vary among individuals based on adherence to post-procedure instructions and other factors.

Will stitches be required after the treatment?

In the context of minimally invasive TenJet procedures, the necessity for stitches may be eliminated.

Does insurance cover TenJet procedures?

Many insurance providers offer reimbursement for tendon treatment procedures, including those involving TenJet. However, coverage details can vary, so it is advisable to consult with your insurance provider to understand specific terms and conditions.

  • Dear Doctor Etelzon, Thank you again. I am starting to feel more like myself again...I couldn't say the problem is totally gone, but a big weight has been lifted...Today...I decided to go and do my nails which I did not do for a long time after the incident. I also asked my daughter if we could go to the park. These are things I normally enjoy but forgot about them for a few months now.
