Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser systems cannot simultaneously deliver multiple wavelengths of laser energy without interference, which complicates and inefficiencies treatments for skin pathologies like dermal rhytides and telangiectasias, as sequential application of different wavelengths alters skin properties, reducing absorption of therapeutic cytokines.
Innovation Solution
A therapeutic laser system that delivers multiple wavelengths simultaneously and spatially separates them to prevent interference, allowing for instantaneous effects and targeted tissue penetration, thereby eliminating the need for sequential applications and enhancing cytokine release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wavelengths of laser energy are applied sequentially to treat skin pathologies, then different tissue depths can be targeted, but the treatment time increases and the second wavelength is scattered by the coagulated and swollen tissue from the first wavelength
Solution Approach 1:
The patent combines multiple laser wavelengths into a single handpiece that can deliver both wavelengths simultaneously or in rapid succession to the same treatment area. This merging of multiple laser systems into one device eliminates the need for sequential treatment sessions, reducing overall treatment time while maintaining the ability to target different tissue depths with appropriate wavelengths
2Adaptability or versatility
If multiple wavelengths of laser energy are applied sequentially to treat skin pathologies, then different tissue depths can be targeted, but the device complexity increases requiring multiple separate laser systems
Solution Approach 1:
The patent integrates multiple laser wavelength sources into a single handpiece assembly, combining what would traditionally require separate laser systems into one unified device. This reduces device complexity and operational burden while maintaining the versatility to treat different tissue depths with appropriate wavelengths
Solution Approach 2:
The handpiece is designed as a universal platform that can deliver multiple laser wavelengths through different applicator tips or configurations, allowing a single device to perform functions that previously required multiple specialized systems
3Temperature
If a first wavelength of laser energy is applied to coagulate tissue, then deep tissue effects are achieved, but the coagulated and swollen skin swallows and scatters the second wavelength subsequently applied
Solution Approach 1:
The system delivers the first wavelength that creates initial tissue coagulation and swelling, then immediately follows with the second wavelength while the tissue is still in its pre-swollen state. This preliminary action approach ensures that the second wavelength is absorbed effectively before tissue changes can interfere with its propagation and absorption
Solution Approach 2:
The patent employs continuous or rapidly sequential delivery of multiple wavelengths without interruption, maintaining the useful action of laser energy absorption and tissue heating throughout the treatment process. This continuous action prevents the interruption that would occur if waiting for tissue to return to normal state between wavelengths
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively treats skin conditions by ensuring simultaneous, non-interfering delivery of multiple wavelengths, improving treatment efficiency and cytokine release in different tissue layers, reducing treatment complexity and cost.
Implementation Method 1
a first beam of first wavelength laser energy and a second beam of second wavelength laser energy are administered simultaneously onto a treated tissue in a single application
Implementation Method 2
different modalities of energy in order successfully treat the pathologies to which they are applied... the irradiation of the skin with a first wavelength of laser energy modifies the skin by coagulating tissue within the skin... These effects alter the propagation of laser light within the skin

AI summary
The invention provides a laser system and method for administering multiple beams of laser energy in tissue treatment applications. The system administers the beams simultaneously in a distribution pattern of spatially separated overlapping and non-overlapping regions on a tissue. The simultaneous administration and distribution pattern permit the beams to propagate within a tissue without producing the light scattering effects that characterize the sequential application of multiple laser beams to a tissue.
