Laser LAHTA-MILON
Laser LAHTA-MILON, a laser surgical device for photodynamic and hyperthermic treatment; programmable; 9444-003-57906795-2003; registered in the Russian Federation, Reg. No. 29/01050603/5828-03.
Designed and manufactured by MILON LASER Ltd (Russia, Saint-Peterburg) with the participation of RADA-PHARMA Ltd (Moscow).
The design of the dual-beam laser device is based on two laser semiconductor modules with a different wavelength; microprocessor-controlled, equipped with flexible software.
Separate radiation couplings enable the individual or combined use of beam channels. The device allows the dissection and coagulation operations in cancerology, general, cosmetic surgery, ENT surgery, gynecology, and other treatments.
The device provides:
– opportunity of separate and combined use of photodynamic, surgical, and hyperthermic treatments of tissue;
– complex use of the photodynamic channel with all types of patented photosensitizers.
– successful test with the use of Radachlorin, a new high-efficiency preparation;
– continuously pulsed and periodic pulsed radiation mode set by preprogramming;
– radiant power monitoring;
– setting-up and control of emission exposure and its energy dose by direct readings countdown readings;
– user friendly display format, an advisory subprogram containing reference data;
– customer-oriented fiber optic kits;
– small dimensions, low weight and power consumption;
– single-phase voltage;
– high reliability; long-life operation.

DIOMED 630 PDT
The DIOMED 630 PDT Laser is intended for use in Photodynamic Therapy (PDT) as a source for the photoactivation of PHOTOFRIN‚ (porfimer sodium) for Injection for:
- palliation of patients with completely obstructing esophageal cancer, or of patients with partially obstructing esophageal cancer who, in the opinion of their physician,
- reduction or obstruction and palliation of symptoms in patients with completely or partially obstructing endobronchial nonsmall cell lung cancer (NSCLC), and
- treatment of microinvasive endobronchial NSCLC in patients for whom surgery and radiotherapy are not indicated
The DIOMED 630 PDT incorporates operator features:
- Quick to set up
- Control of laser energy delivery by handswitch or footswitch
- An internal power meter for calibration of optical fibers, enabling accurate dosing of the patient
- Automatic selection of laser energy dosimetry – using the ‘touch-screen’ menu, the operator simply identifies the treatment area and fiber length to be used and the software calculates the laser power and duration required for each treatment
- Option to set custom treatment parameters in joules of energy delivered or time elapsed
- Laser software records the power and energy delivered during each treatment session
The DIOMED 630 PDT is the only diode laser available for photodynamic therapy (PDT) in conjunction with PHOTOFRIN‚ (porfimer sodium). It provides up to 2000mW of 630nm continuous wave laser radiation to the tip of a flexible delivery fiber optic. The DIOMED 630 PDT incorporates an internal calibration sphere to measure power output at the fiber optic tip.

HIGH POWERED HELIUM NEON LASERThe He-Ne laser is one of the most commonly used visible light lasers, giving off a red laser beam with a wavelength of 0.632mm. It has been used extensively for medical treatment, holography, laser light displays and more. Its low cost and long lifetime make it extremely convenient for use. However, the sole weakness of this laser is low output power limiting the number of applications, especially medical applications, which can be done with this laser. |
|
Characteristics
- The high power He-Ne laser is ideal for PhotoDynamic Therapy, used in the fight against cancer.
- It delivers precise power at desired wavelengths
- It can also be used for the following:
- internal laser surgery against polyps and other growths
- Stimulating hair growth
- cutaneous applications
- Non-medical uses include the following:
- Large screen laser shows
- Open air laser shows
- Powerful laser pointers for speakers in Auditoriums and large halls
- Pollution or dust monitors
