ClariVein® Mechanochemical Ablation in Los Angeles & Walnut
At Vein Care Medical Center in Los Angeles & Walnut, Dr. Michael D. Landau offers ClariVein® — one of the most advanced minimally invasive varicose vein treatments available today. ClariVein® uses Mechanochemical Ablation (MOCA), a technique that combines two highly effective approaches: mechanical disruption of the vein wall and precise application of a sclerosing agent. Together, these actions close the diseased vein without the heat, tumescent anesthesia, or thermal energy required by laser or radiofrequency procedures.
Request an AppointmentWhat Is Mechanochemical Ablation (MOCA)?
Mechanochemical Ablation is a catheter-based approach to closing incompetent veins. ClariVein® achieves this through a specialized catheter with a uniquely engineered rotating tip — two to three times thinner than catheters used in laser ablation or radiofrequency ablation. As the tip rotates at high speed inside the targeted vein, it mechanically disrupts the inner lining of the vessel. Simultaneously, a liquid sclerosing agent is infused through the catheter, chemically closing the vein from the inside. The combination of mechanical and chemical action results in reliable vein closure with excellent long-term outcomes.
How the ClariVein® Procedure Works
The ClariVein® procedure at Vein Care Medical Center is straightforward and efficient:
- A single, small entry point in the skin is all that is needed — no multiple incisions.
- The ClariVein® catheter is guided into the diseased vein using ultrasound imaging.
- Only a local anesthetic at the insertion site is required — no tumescent anesthesia injected along the length of the vein.
- The rotating tip activates and the sclerosing agent is delivered as the catheter is withdrawn.
- The entire procedure typically takes approximately 30 minutes.
Because no heat is used, patients experience significantly less discomfort compared to thermal-based treatments, and there is no risk of skin or nerve damage from thermal energy.

ClariVein® — Frequently Asked Questions
What makes ClariVein® different from laser or radiofrequency vein treatments?
ClariVein® uses Mechanochemical Ablation (MOCA) — a non-thermal technique that closes veins through a combination of mechanical disruption and a sclerosing agent, rather than heat. This means no tumescent anesthesia is needed along the length of the vein, there is no risk of heat-related nerve or skin damage, and patients typically experience less post-procedural discomfort than with laser or radiofrequency ablation.
Is ClariVein® painful?
ClariVein® is designed to be as comfortable as possible. Only a small amount of local anesthetic is applied at the catheter insertion point. Because no heat is generated inside the vein, the procedure is associated with minimal discomfort during treatment and very little soreness afterward. Most patients describe the experience as far more comfortable than they expected.
How long does a ClariVein® procedure take?
The ClariVein® procedure typically takes about 30 minutes in-office. There is no need for sedation, and patients can resume their normal activities immediately following treatment. You can drive yourself home and return to light work the same day.
How effective is ClariVein® for closing varicose veins?
Clinical studies show that Mechanochemical Ablation with ClariVein® achieves successful vein closure in approximately 90% of treated cases. Dr. Landau monitors results with follow-up ultrasound imaging and provides any additional treatment needed to ensure complete and lasting closure.
Does insurance cover ClariVein® treatment?
Coverage for ClariVein® depends on your insurance carrier and whether the treatment is deemed medically necessary. Vein Care Medical Center participates in Medicare and works with many insurance plans. If your varicose veins are causing symptoms such as pain, swelling, or skin changes, there is a good chance your treatment will qualify for coverage. Our team can assist you in verifying your benefits before your procedure.
What should I expect after ClariVein® treatment?
After treatment, you will be asked to wear compression stockings for a period of time as directed by Dr. Landau. You can walk immediately and return to light activity the same day. Some mild bruising or tenderness at the insertion site is possible but typically resolves quickly. Dr. Landau will schedule a follow-up ultrasound to confirm the treated vein has closed properly.
