Holmium laser system for stone management & soft tissue.

Odyssey 30 In Action

Simple Retrograde Kidney Stone
A flexible ureteroscope is used to access the kidney (retrograde). Using a 200 micron core fiber, laser energy (10 Hz, 1.0 J) is used to break up the stone. Once the stone is fragmented, a basket is used to retrieve the remaining particles.

Percutaneous Staghorn Calculus
This patient had staghorn calculus filling the entire kidney. Two ESWL/USL treatments cleared 80% of the stone burden. This third and final procedure was completed using a holmium laser. The laser was used to fragment larger pieces so they could be retrieved with a stone basket. The smallest fragments were then "vacuumed" up.

Bladder Tumor Resection
A semi-rigid ureteroscope was used to access the bladder with the patient under topical anesthesia. Using a 200 micron core fiber, laser energy (5 Hz, 0.5 J) is used to excise the tumors. The laser was also used to cauterize the tissue after excision.

Laser Lithotripsy

The Odyssey is the ideal laser system for endourologists. The laser's 2100 nm infrared output can disintegrate stones and ablate tissue with minimal lateral tissue damage. An endourologist can choose from a wide range of fiber sizes to operate throughout the urinary tract. Larger core fibers can be used with rigid endoscopes to reach the ureter and the bladder. Smaller core fibers can be used with flexible ureteroscopes to reach the renal calyces.

Stone Management & Soft Tissue Laser

Odyssey 30 Holmium Laser System

How the New Odyssey holmium laser system treats stone & soft tissue effectively?

The holmium laser wavelength is ideal for endourology. It is highly absorbed by water making it efficient and effective for disintegrating calculi in an aqueous environment or ablating tissue in contact mode.

Clinical Feedback

Ralph V. Clayman, M.D.

 Conclusions: Variable pulse-width lasers allow the operator to control retropulsion. When treating ureteral calculi, retropulsion can be reduced by a longer pulse width without compromising fragmentation efficiency. For caliceal calculi, a longer pulse width provides slightly more effective stone fragmentation possibly because of less fiber-tip damage.

Michael Grasso III, M.D.

 Conclusions: These results confirm that the holmium laser is an excellent and safe device for intracorporeal lithotripsy, with the ability to fragment stones of all compositions. It has particular efficacy in complex clinical presentations and, if the efficacy of soft tissue applications is confirmed, the holmium laser may represent a cost effective, multipurpose urologic laser.

Demetrius H. Bagley, M.D.

 Conclusions: The longer pulse width setting with the Ho:YAG laser results in less displacement of phantoms after one pulse and allows more energy delivery prior to movement with continuous pulses. This was found to be the case regardless of laser fiber diameter or pulse energy. Clinically, adjusting the laser to the longer pulse width may cause lessretropulsion at the same laser settings, thereby improving the efficiency of stone fragmentation.

Frequently Asked Questions

Q Why should I buy the Odyssey over the competition's product?

ABest Technology—the Odyssey 30 uses the latest laser technology which allows us to deliver a more efficient laser at a very competitive price.
Established Track Record—Convergent has been a market leader in medium-powered holmium lasers since 1995; we have proven our capability to design, manufacture, and support our laser systems.

Q What features set the Odyssey apart from its competition?

A Compact and efficient design, variable pulse technology, green aiming beam, top-quality fiber-optics, and proven reliability.

Q I'm under the impression that lasers are difficult and expensive to maintain. How reliable is the Odyssey laser?

A The Odyssey was completely re-designed for greater reliability and serviceability over its predecessor and competition. Under normal operating conditions, the laser should last many years without any mandatory service needs. However, we do recommend a preventive maintenance check-up at 6-12 month intervals depending on the operating environment and frequency of use.

Q If I'm planning to use the Odyssey in an office-based environment, do I need any special personnel to operate and maintain the Odyssey? What if the laser system stops working?

A Convergent provides in-service training with each new Odyssey laser system purchase. The in-service training is designed to provide adequate information to each participant. After completion of the training program, each participant will be familiar with basic troubleshooting procedures and be able to comfortably operate the laser system. Additionally, the Odyssey performs self-diagnostics and will inform the operator when it detects any condition that is out of the ordinary. The Odyssey comes with a one-year parts and labor warranty. Extended warranties are available.

Q Is the Odyssey available for sale outside of the U.S.?

A For international inquires, please contact our sales department at This email address is being protected from spambots. You need JavaScript enabled to view it.

Q Do I need any special electrical utilities to operate the Odyssey laser?

A The Odyssey 30 can operate from a U.S. standard 115 to 230V at 50/60Hz.

Odyssey 30

The Odyssey is the ideal laser system for endourologists. The laser's 2100 nm infrared output can disintegrate stones and ablate tissue with minimal lateral tissue damage. An endourologist can choose from a wide range of fiber sizes to operate throughout the urinary tract. Larger core fibers can be used with rigid endoscopes to reach the ureter and the bladder. Smaller core fibers can be used with flexible ureteroscopes to reach the lower pole of the kidney.

T-1470 ProTouch

The ProTouch is the first 1470 nm laser system designed specifically for treating BPH. Its 1470 nm wavelength is highly absorbed by both water and hemoglobin making it ideal for ablating soft tissue. As the laser energy ablates tissue, it simultaneously seals off the blood vessels to minimize bleeding. In contrast to KTP lasers, the ProTouch's patented fiber tip protection system allows the surgeon to operate in contact mode, which provides the tactile feel of a scalpel or electrode loop without destroying the fiber.

T-1470 LiteTouch

The T-1470 LiteTouch is a portable diode laser system for ENT and aesthetic applications including nasal and laryngeal polyps, endoscopic sinus surgery, papillomatosis, and lipolysis. Its 1470 nm wavelength is highly absorbed by both water and hemoglobin making it ideal for ablating soft tissue. As the laser energy ablates tissue, it simultaneously seals off the blood vessels to minimize bleeding.


Convergent has been a leading provider of high quality holmium laser fibers since 1994. All our fiberoptic delivery systems use the most durable, flexible fibers available.
