Multimodal Neuromodulatory Patch for Targeted Transdermal Drug Dwell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable medical devices lack the ability to target specific tissues along a specific vector and depth for analgesic compound delivery, and they fail to maintain the compounds at the site of action effectively, leading to inefficiencies and systemic side effects.
Innovation Solution
A wearable multimodal device that combines transcutaneous electrical stimulation and magnetic fields to vector and maintain therapeutic compounds like NSAIDs and analgesics at targeted tissues using electromagnetic fields, enhancing transdermal delivery and dwell time without causing pain or discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transdermal delivery of analgesic compounds is used, then pain relief is achieved, but the compounds cannot be maintained at the site of action and are lost to systemic circulation
Solution Approach 1:
The device employs sensors to detect physiological parameters (such as pain levels, inflammation markers, or compound concentration) and uses this feedback to dynamically adjust the delivery rate of analgesic compounds. This closed-loop control ensures the compound is maintained at therapeutic levels at the site of action while minimizing systemic loss, as the system responds in real-time to actual tissue conditions rather than using fixed dosing protocols.
Solution Approach 2:
The patent introduces a localized reservoir or depot system as an intermediary between the transdermal delivery mechanism and the target tissue. This intermediary structure holds the analgesic compound at the site of action, allowing controlled release directly where needed and preventing premature entry into systemic circulation. The depot acts as a buffer that maintains local concentration while reducing systemic exposure.
2Reliability
If higher doses of analgesic compounds are delivered to achieve effective pain relief, then therapeutic efficacy increases, but systemic toxicity increases
Solution Approach 1:
The device creates a highly localized concentration gradient of the analgesic compound precisely at the site of action through targeted transdermal delivery. By concentrating the therapeutic agent only where needed rather than distributing it systemically, the system achieves high local efficacy while maintaining low systemic concentrations, thereby avoiding toxicity. This spatial differentiation of drug concentration is the core mechanism for resolving the efficacy-toxicity tradeoff.
Solution Approach 2:
The patent employs a disposable transdermal patch or delivery device that is applied directly to the skin over the affected area. This single-use, localized delivery system ensures that each patient receives a controlled, limited dose that acts only at the application site, preventing accumulation and systemic toxicity while providing sufficient local analgesia. The disposable nature also eliminates cross-contamination and dosing errors from reuse.
3Adaptability or versatility
If traditional wearable medical devices deliver compounds systemically, then broad coverage is achieved, but specific tissue targeting and depth control are lost
Solution Approach 1:
The patent transitions from systemic (whole-body) delivery to transdermal (surface-to-depth) delivery by exploiting the dimensional aspect of skin penetration. The device delivers compounds through the skin barrier directly to underlying tissues at controlled depths, adding a spatial dimension (from systemic distribution to localized deep tissue targeting) that enables precise anatomical targeting while maintaining adaptability to different treatment sites through adjustable delivery parameters.
