T-1470 LiteTouch In Action

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.
Indications
Urology
Excision, vaporization, incision, coagulation, ablation of tissues with excellent hemostasis.
Examples include:
- Vaporization of uretheral tumors
- Release of urethral stricture
- Removal of bladder neck obstruction
- Excision and vaporization of condyloma
- Lesions of external genitalia
Ear, Nose and Throat and Oral Surgery (Otolaryngology)
Hemostasis, incision, excision, ablation, coagulation and vaporization of tissue from the ear, nose, throat and adjacent areas including soft tissue in the oral cavity.
Examples include:
- Removal of benign lesions from the ear, nose and throat, e.g. turbinectomy
- Excision and vaporization of vocal cord nodules &am; polyps, e.g. tonselectomy, uvelaplasty
- Incision and excision of carcinoma in situ, e.g. bronchoscopy
- Ablation and vaporization of hyperkeratosis
- Excision and vaporization of herpes simplex I and II
- Neck Dissection
Pulmonary Surgery
Hemostasis, vaporization, coagulation, incision, excision and ablation of soft tissue in the pulmonary system.
Examples include:
- Tracheobronchial malignancy or stricture
- Benign and malignant pulmonary obstruction
- Endoscopic pulmonary applications
Gynecology
Ablation, excision, incision, coagulation, hemostasis and vaporization of gynechological tissue.
Examples include:
- Endometrial ablation
- Excision or vaporization of condylomata acuminata
- Vaporization of cervical intraepithelial neoplasia
- Cervical conization
- Menorrhagia
Features and Benefits
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 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 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.
Convergent 200 micron and 400 micron fiber delivery systems for the T-1470 LiteTouch can deliver high peak power to ablate all types of soft tissues.

"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.
