Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:

[0022] FIG. 1 is a simplified illustration of a laser-based system and method for vaginal rejuvenation, in accordance with a non-limiting embodiment of the present invention.

DETAILED DESCRIPTION OF EMBODIMENTS

[0023] Reference is now made to FIG. 1, which illustrates a laser-based vaginal rejuvenation system 10, constructed and operative in accordance with a non-limiting embodiment of the present invention.

[0024] The system 10 includes a laser source 12 coupled to an optical waveguide 14 which has a laser output portion 16. The laser source 12, optical waveguide 14 and laser output portion 16 are also collectively referred to as the laser. The optical waveguide 14 is movable inside a vaginal housing 18, which is transparent to the laser energy emitted by the laser source 12 and which exits the laser output portion 16. The optical waveguide 14 is coupled to an actuator 20 configured to move optical waveguide 14 along a longitudinal path 22 inside vaginal housing 18.

[0025] The vaginal housing 18 may be a tubular structure with a distal end 24, which may be rounded and closed. In another option, distal end 24 is open or openable, which may be advantageous for enabling the laser output portion 16 to distally protrude out of the housing for external laser treatment of the genital labia. Of course, this external treatment may also be done with the laser output portion 16 inside the housing with a closed distal end. The vaginal housing 18 may be constructed of glass, plastic or any other suitable material transparent to the laser energy emitted by the laser. Without limitation, vaginal housing 18 may be a transparent tube with an OD of 3-20 mm and ID of 1-18 mm, or preferably OD of 9-10 mm and ID 1-3 mm. The proximal end 26 of vaginal housing 18 may be sealed. The vaginal housing 18 may include depth markings and/or longitudinal marking for side fiber option.

[0026] Actuator 20 may be, without limitation, a servomotor, linear actuator, or a simple displacement mechanism using an off-center arm on a rotating wheel to displace the fiber in and out at a controlled rotational speed.

[0027] Instead of using actuator 20, the displacement of the fiber inside the tube can be done manually.

[0028] In a preferred embodiment, laser source 12 is a diode laser and optical waveguide 14 is an optical fiber (that is, the laser is a diode fiber laser).

[0029] The non-ablative treatment may be carried out with different laser wavelengths that have different absorption coefficients so that the laser energy penetration can be at different tissue depths.

[0030] The wavelengths can be individual wavelengths or a combination of wavelengths, such as but not limited to: 980 nm (medium depth of penetration), 1064 nm (greater depth of penetration) or 1470 nm (more superficial depth of penetration). All of these wavelengths can be achieved with a diode laser with a power of 5-60 watts (continuous or pulsed).

[0031] Without limitation, the laser energy can be transmitted in a fiber optics with a diameter of 300-1000 m.

[0032] The optical fibers may be, without limitation: a side-firing fiber which can emit the energy at angles such as 70-90 from the optical axis; a radial fiber, which emits light at 360 from the optical axis; or a diffused end portion fiber, in which light is scattered around the distal end, so that the light-emitting pattern of the diffusing fiber exhibits a uniform distribution along the distal end (e.g., the diffused distal part may be 0.5-4 cm in length and emits the light at 360 along the diffused length).

[0033] In use, the vaginal housing 18 is easily inserted into the vagina due its small diameter. The vaginal housing 18 does not need to touch the vaginal wall since the laser beam is not focused; thus there is no need for contact with the vaginal wall.

[0034] Different modes of treatment may be used depending on the laser used. For example, for a side-fire fiber, the fiber may be rotated 360 by actuator 20 around the axis 22 in order to cover the entire inner circumference of the vaginal wall. The fiber is then displaced incrementally linearly and proximally along axis 22 (e.g., about 1 cm) and the laser procedure is repeated.

[0035] For a 360 radial fiber or diffused fiber laser (higher laser power), there is no need to rotate the fiber and the fiber is only displaced linearly and incrementally. The incremental steps may be larger for a diffused laser (e.g., between 1-40 mm).

[0036] By maintaining the vaginal housing 18 in a stationary position in the vagina and moving the fiber inside the tube, there is no discomfort to the patient, which is a significant advantage over the prior art. In this manner, the collagen along the vagina length is thermally treated effectively, painlessly and rapidly.
