Abstract: A method and a device for autografting of fat microparticles containing stem cells of various types, injected into scars, or stretch marks, and/or other cutaneous injuries, at epidermis-dermis level is presented. Fat is taken from the patient in the periumbilical area, where large quantities of mesenchymal stem cells exist. After reduction in size by means of a thin grid emulsifier filter the fat microparticles are loaded into a tank of a multi-needle gun, such as used for tattoos. The multi-needle tattoo gun injects the fractionated fat microparticles into the epidermis-dermis of scars, and/or stretch marks and/or other skin defects or even internal injuries. The injected fat particles trigger tissue regeneration, deleting scars, stretch marks, wrinkles and/or other defects or skin damages in 3-4 weeks.

Abstract: A minimally invasive method for treating varices in especially sensitive areas, including pelvic varices in females, varicoceles, and also oesophageal varices is presented. The method comprises the steps of making a micro incision into the blood vessels of a patient, endoscopically inserting a catheter device into the blood vessel of a patient and advancing the distal end of the catheter to reach the varix or varices. For treatment of male varicocele, insertion is preferably made directly at the testicle. Alternatively, insertion can be made in the femoral vein and advanced using a catheter. Preferably, x-ray, angiography, or other imaging techniques are used to visualize and position the catheter. An optical fiber is then inserted into the catheter and the distal end is advanced to a predetermined point near the varix or varices. Optical fiber distal end is preferably a slim, radial 360 degree emitting fiber end.

Abstract: An improved system for safe and efficient generation of plasmas and vapors bubbles with continuous wave radiations and low levels of power densities, sufficient to treat medical pathologies and to avoid the creation damage to healthy tissue is provided. Transmission means in different configurations are used to achieve a high absorption in water, which is able to initiate plasma with low levels of power density. Once plasma and vapor bubbles are formed, they absorb other wavelengths in addition to the one that initiated it. Other wavelengths, more efficiently generated by diodes or diode pumped lasers, are added into the beam to improve treatment efficiency. This modulated plasma produces fast tissue ablation and good hemostasis effect with minimal overheating of remaining tissue. After plasma and high-energy vapors are generated, only laser radiation that passes through the plasma bubble directly interacts with soft tissues.

Abstract: An improved method and device for safe and efficient medical applications is provided. In a preferred embodiment, based on using the inherent benefits of laser diodes (such as efficient power generation from a reliable and compact solid state device), plasmas and high energy vapors are produced for medical applications with power levels and power densities sufficient to treat medical indications and avoid the creation of extensive damage zones. Transmissions means in different configurations are used to achieve a high power density, which is able to initiate plasma and high-energy vapor at the tip. Once a sparkless plasma and high energy vapor bubbles are formed, it is often found that it will also absorb other wavelengths in addition to the one that initiated it. As a consequence, other wavelengths more efficiently generated by diodes or diode pumped lasers may be added into the beam in order to improve treatment efficiency.

Abstract: A device for improved surgical procedures to remove unwanted or hyperplasic tissue from a patient during laser ablation, urological treatments, benign prostatic hyperplasia treatments and other applications. Specially prepared optical waveguide tips allow for enhanced irradiation of desired tissues with light sources including laser diodes, bright LEDs or lamps. A significant fraction of the optical radiation, being transported in the waveguide, is coupled out of the waveguide into the surrounding medium through a peripheral surface at or near the distal end. The optical radiation is chosen to have an appropriate wavelength and sufficient power density, so that the surrounding medium will be changed in the vicinity of at least a part of the peripheral surface area. The changes of the surrounding medium result in a change of its refractive index such that the optical radiation is redirected.

Abstract: A system/method for destruction/ablation of stones, calculi or other hard substances using laser is disclosed. Lithotripsy is particularly benefitted. The system comprises a diode laser source, one or more optical fibers and a liquid delivery system creating a liquid environment around stones (calculi). At least one emitted wavelength is highly absorbed in surrounding/covering medium, causing evaporation and cavitation effects that lead to stone/calculi destruction. Different radiation configurations may be used. in one embodiment continuous radiation is used to create sparkler-less plasma bubbles to destroy hard substances. In another embodiment high peak power pulsed radiation is used. Wavelengths of 1470 nm, 1940 nm, or 1550 nm are preferred. Additionally device/method is used with another wavelength having absorption in water e.g. 980 nm. Safer/improved methods/system provide enhanced lithotripsy treatments with shorter treatment times to destroy a wider range of stones with less tissue damage risk.

Abstract: A system and method for the destruction/ablation of stones, calculi or other hard substances by means of laser energy is disclosed. As a consequence, several important medical treatments can be performed, especially lithotripsy. The system comprises a diode laser source emitting at least at one wavelength, one or more optical fibers which convey laser radiation to the treatment site and a liquid delivery system used for creating a liquid environment around the stones (calculi). The laser device emits at least one wavelength which is highly absorbed in the surrounding/covering medium, thus causing evaporation and cavitation effects that lead to stone/calculi destruction. Different radiation configurations may be used. In one embodiment continuous radiation is used to create sparkler-less plasma bubbles able to destroy hard substances.

Abstract: A method too permanently remove unwanted hair using a diode or other laser source in a post-treatment mode is disclosed. The method is not limited by skin pigmentation, causes no pain, and minimizes damage to surrounding tissue. The hair in the treatment area is first removed using conventional stripping techniques leaving the hair follicles substantially empty. While the follicles are still open, a special photosensitizing lotion is rubbed into the skin and then penetrates in the depth of the follicle. A solvent is then used to clean the surface of the skin from excess photosensitizer, while the photosensitizer remains in the follicles. In this way, the follicular ducts are selectively sensitized. An area containing the follicles is then irradiated by a diode laser in the near IR range and the follicles are thereby killed. There is no waiting time necessary in between different steps of treatment and generally only one application of laser radiation is required.

The device may be operated by a trained professional at three different repetition rate frequencies, selected by the operator to threat different dental conditions. The specific photosensitizer liquid or paste which is activated at a certain wavelength is chosen by the operator to treat different dental conditions. The device is also intended for home dental hygiene at low power.

Abstract: A surgical device is provided that is to be used with standardly available resectoscopes, combining the better qualities of familiar tissue scraping tools and real time imaging with the better qualities of laser radiation surgery. The laser radiation is delivered using side-firing optical fibers and is capable of delivering the amount of power needed to ablate or coagulate tissue. The state of the useful art is advanced by incorporating the ability to ablate as well as coagulate tissue using laser radiation, together with the ability to scrape and/or cauterize tissue and simultaneously use familiar real time imaging capabilities, all fitted into a single device that is used with a standard resectoscope. This allows surgeons to use as many familiar and tested techniques as possible and allows hospitals to purchase the device with minimal additional procurement activity.

Abstract: The device of the present invention pertains to a modified medical laser delivery device with sideways directed radiation that can produce high power densities at a distance further away from the fiber, thereby enabling non-contact ablating procedures to be carried out with lower laser input power levels.
