Bladder Tumor

A Versatile Laser For Most Soft Tissue Indications

The LiteTouch is designed for treating Renal Tumors, Ureteral Tumors, ENT and other soft tissue indications. Similar to the ProTouch, 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, which provides a clean and clear operating field of view.

Features and Benefits

T-1470 LiteTouch Absorption
T-1470 LiteTouch Absorption

1470 nm wavelength is the optimum laser wavelength for soft tissues. It has a high water absorption coefficient similar to the holmium wavelength and is readily absorbed by oxyhemoglobin allowing for low-char hemostatic tissue removal.

Fiber Tip Protection
Fiber Tip Protection

Fiber tip protection system allows the surgeon to work in contact mode without damaging the fiber tip. With KTP lasers, the surgeon has to position the fiber tip 2-3 mm from the tissue surface to avoid overheating the fiber tip.

Top Hat Waveform
Fast-Rise-Time Top Hat Waveform

Top-hat waveform delivers 20% more effective power compared to typical Gaussian waveform lasers. At 25 W setting in contact mode, the T-1470 LiteTouch removes tissue twice as fast as an equivalent-powered CO2 laser.

"The LiteTouch laser is a unique laser which offers efficient coagulation with minimum thermal damage. It provides high precision and superb control during airway resection procedures with minimal bleeding."

Frequently Asked Questions

Frequently Asked Questions

Q Why should I buy the T-1470 LiteTouch over the competition's product?

A The T-1470 LiteTouch uses the latest diode laser technology to deliver a more efficient laser at a very competitive price. Convergent has been a market leader in lithotripsy laser systems since 1995; we have proven our capability to design, manufacture, and support our laser systems.

Q What features set the T-1470 LiteTouch apart from its competition?

A The T-1470 LiteTouch offers compact and efficient design, ease-of-use, top-quality fiber-optics, and proven reliability. In addition, built-in temperature control reduces fiber damage due to overheating at the tissue interface.

Q I'm under the impression that lasers are difficult and expensive to maintain. How reliable is the T-1470 LiteTouch laser?

A The T-1470 LiteTouch was designed for reliability and serviceability. Under normal operating conditions, the laser should last many years with minimal 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 T-1470 LiteTouch in an office-based environment, do I need any special personnel to operate and maintain the T-1470 LiteTouch? What if the laser system stops working?

A Convergent provides in-service training with each new T-1470 LiteTouch 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 T-1470 LiteTouch performs self-diagnostics and will inform the operator when it detects any condition that is out of the ordinary. The T-1470 LiteTouch comes with a one-year parts and labor warranty. Extended warranties are available.

Q Is the T-1470 LiteTouch available for sale outside of the U.S.?

A 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 T-1470 LiteTouch laser?

A The T-1470 LiteTouch can operate from a U.S. standard 115 - 230 VAC at 50/60Hz.

Products & Services

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.
