Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for esophageal cancer, such as surgery, radiation, and chemotherapy, are invasive and require sedation, lacking a non-invasive method to effectively target and kill cancer cells without systemic damage.
Innovation Solution
Inhaling heated air through a face mask at controlled temperatures below sauna levels to heat the tracheoesophageal party wall sheath membrane, conducting heat to adjacent esophageal tumors, using a heat gun with safety locks and temperature monitors to ensure effective treatment without invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgery, radiation, or chemotherapy is used to treat esophageal cancer, then cancer cells can be killed, but the treatment becomes invasive and requires sedation
Solution Approach 1:
The patent replaces mechanical surgical intervention with thermal energy delivery. Instead of physically removing or cutting into the tumor through surgery, the invention uses heated air delivered via a face mask to thermally ablate cancer cells through the tracheoesophageal membrane, substituting mechanical trauma with controlled thermal effects.
Solution Approach 2:
The patent introduces an intermediary medium (heated air) that transfers thermal energy from the external environment to the target tissue. The face mask serves as an intermediary device that delivers the heated air to the trachea, which then conducts heat through the tracheoesophageal membrane to the esophageal tumor, avoiding direct contact with the tumor site.
2Reliability
If high temperature is applied to kill cancer cells, then treatment effectiveness improves, but risk of damaging normal tissue increases
Solution Approach 1:
The patent applies local quality by concentrating thermal energy specifically at the tumor site through the thin tracheoesophageal membrane while maintaining lower temperatures in surrounding normal tissues. The face mask delivers heat locally to the trachea adjacent to the tumor, and the membrane's thinness (0.5-2mm) enables localized heat transfer to the esophageal cancer cells without extensively heating distant normal tissues.
Solution Approach 2:
The patent utilizes parameter changes by controlling the temperature, duration, and delivery method of heated air to achieve selective cancer cell destruction. By adjusting these parameters, the treatment can reach temperatures sufficient to kill cancer cells (113°F or higher) while limiting exposure time and spatial distribution to prevent excessive damage to normal tissues.
3Manufacturing precision
If invasive procedures are used to treat esophageal cancer, then direct access to tumor is achieved, but patient discomfort and complexity increase
Solution Approach 1:
The patent applies universality by using a single face mask device that can treat esophageal cancer without requiring multiple specialized invasive instruments. The face mask serves multiple functions: delivering heated air, monitoring temperature, and providing a non-invasive interface between the external environment and the internal tumor target, eliminating the need for separate surgical tools, sedation equipment, and post-procedure care systems.
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 method effectively kills esophageal cancer cells through apoptosis by conducting heat from the trachea to the esophagus, avoiding invasive surgery and sedation, with lower toxicity and cost, and utilizing non-invasive temperature monitoring.
Implementation Method 1
The inhaled heated air will heat the very thin tracheoesophageal party wall sheath membrane between the esophagus and the respiratory trachea in the throat. The tracheoesophageal party wall sheath membrane therefore can heat the esophageal cancer tumor adjacent to the heated trachea and tracheoesophageal party wall sheath membrane

AI summary
A method for treating esophageal cancer in situ with heated air that can be inhaled through a face mask, at an elevated temperature less than sauna air temperatures and at a constant positive air pressure. The inhaled heated air will heat the very thin tracheoesophageal party wall sheath membrane between the esophagus and the respiratory trachea in the throat. The tracheoesophageal party wall sheath membrane therefore can heat the esophageal cancer tumor adjacent to the heated trachea and tracheoesophageal party wall sheath membrane. The heated air will be inspired/inhaled through the mouth and into the trachea/windpipe. Then the trachea and trachea tube under heated constant positive pressure will then transfer heat through and to the esophagus wall, and esophagus and tumor. The heat from the heater air inspiration through the trachea migrates/transmits/disperses across the membrane separating the trachea/windpipe from the esophagus and hits the esophagus with heat.
