Abstract
A system for treating a region of the epidermis, including: at least one laser energy source; a time control device to generate a laser beam; a laser energy focusing system arranged and produced to direct a laser beam on the region of the epidermis. The control device generates a laser beam including a plurality of composite pulses, emitted at a base frequency, each composite pulse including a sequence of sub-pulses at a higher frequency than the base frequency.
Claims10
A method for treating a portion of epidermis of a patient, the method comprising:
- emitting a laser beam comprising one or more composite pulses, emitted at a base frequency, each of said one or more composite pulses comprising a sequence of sub-pulses at a higher frequency than said base frequency, each of said composite pulses comprising a first interval of continuous pre-pulse emission and a second sub-pulse sequence emission interval, said sub-pulse sequence comprising a plurality of sub-pulses, said sub-pulse sequence emission interval comprising a train of sub-pulses following said pre-pulse emission, said first interval of continuous pre-pulse emission comprising a first interval pre-pulse emission duration, each of said subsequent sub-pulses having a sub-pulse duration, said first interval pre-pulse emission duration being greater than said sub-pulse duration of each of said sub-pulses.
A method for treating a portion of epidermis of a patient, the method comprising:
- emitting a pulsed laser beam toward said portion of epidermis, said pulsed laser beam comprising a plurality of composite pulses emitted at a base frequency, each of said composite pulses comprising a sequence of sub-pulses, said sequence of sub-pulses being emitted at a higher frequency than said base frequency, each of said composite pulses comprising a first interval of continuous pre-pulse emission followed by a sub-pulse sequence emission interval, said sub-pulse sequence emission interval comprising a plurality of sub-pulses following said pre-pulse emission, said first interval of continuous pre-pulse emission having a greater duration than each of said subsequent sub-pulses;
- emitting, in combination in time with said laser beam, a radiofrequency current toward said portion of epidermis.
A method for emitting energy through a handpiece, the method comprising the steps of:
- providing a device with a handpiece;
- emitting a pulsed laser beam and a radiofrequency current coordinated in time with each other, said pulsed laser beam comprising a plurality of composite pulses emitted at a base frequency, each of said composite pulses comprising a continuous pre-pulse emission interval followed by a sub-pulse sequence emission interval, said continuous pre-pulse emission interval comprising a continuous pre-pulse emission, said sub-pulse sequence emission interval comprising a plurality of sub-pulses following said pre-pulse emission, said continuous pre-pulse emission interval comprising a pre-pulse emission interval duration, each of said sub-pulses comprising a sub-pulse duration, said pre-pulse emission interval duration being greater than said sub-pulse duration of each of said sub-pulses, said plurality of sub-pulses being emitted at a sub-pulse frequency, said sub-pulse frequency being greater than said base frequency;
- transmitting energy through the handpiece.
A system for treating a region of the epidermis, the system comprising:
- at least one laser energy source to generate a pulsed laser beam having a laser-ablation effect;
- a laser energy focusing system arranged and designed to direct a laser beam on said region of the epidermis;
- a radiofrequency current source with at least one electrode for applying radiofrequency current;
- a control configured to emit said laser beam and said radiofrequency current in a timely-coordinated manner such that said laser beam comprises a plurality of composite pulses emitted at a base frequency, each of said composite pulses comprising a continuous pre-pulse emission interval followed by a sub-pulse sequence emission interval, said continuous pre-pulse emission interval comprising a continuous pre-pulse emission, said sub-pulse sequence emission interval comprising a plurality of sub-pulses following said pre-pulse emission, said continuous pre-pulse emission interval comprising a pre-pulse emission interval duration, each of said sub-pulses comprising a sub-pulse duration, said pre-pulse emission interval duration being greater than said sub-pulse duration of each of said sub-pulses, said plurality of sub-pulses being emitted at a sub-pulse frequency, said sub-pulse frequency being greater than said base frequency.
