Devices and method for prevention and treatment of fungal and bacterial microorganisms

An intravaginal light-based treatment device (ILTD) (100) for treating patient's vaginal disorders, the device comprising:

• a) a main body (101) having a cylindrical shape and a longitudinal axis;
• b) a light source (102);
• c) a power source (103);
• d) a coating (104) over said main body (101);
• and
• e) a flexible tether (105),
• wherein
• said light source emits pulsed light having at least one predefined wavelength suitable for treating said vaginal disorders, and said main body (101) and coating (104) configured to allow said light to pass through and reach vaginal tissue;
• said light source emits said light at predefined intervals and intensities suitable for treating said vaginal disorders;
• said flexible tether (105) is a heat-conduit that removes excess heat generated by said ILTD outside from the vagina;
• said flexible tether (105) is a flexible wire connected to said main body (101) and is configured to retract the ILTD outside from the patient's vagina;
• said coating (104) includes rough regions that are anti-slip regions (106) designed to assist the ILTD to remain in place, as well as in the right/desired position and orientation within the vagina, thereby directing the emitted light in the desired direction;
• and
• said anti-slip regions (106) comprise protrusions (116) extending along the longitudinal axis of the main body, and configured to maintain the ILTD in place after insertion, in the desired position and orientation, thereby facilitating the emitted light to be emitted in the desired direction.
