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

VSEngineering 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

Engineering Contradiction:
Improveability to treat different tissue depthsVSAvoidtreatment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveability to treat different tissue depthsVSAvoidnumber of laser systems required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvetissue coagulation temperatureVSAvoidabsorption of second wavelength
Core Design Contradiction:
TemperatureVSUse of energy by moving object

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #20Continuity of useful action

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.
