Viscous Medication Gel for Sinus Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for chronic sinusitis face challenges in delivering medications to the sinuses effectively, as existing methods often result in insufficient drug concentration, side effects, and poor compliance, with issues such as gastrointestinal side effects, drug waste, and interference with wound healing.
Innovation Solution
A viscous composition, such as a hydrogel, is used for topical drug delivery to the paranasal sinuses, providing extended adherence and minimizing side effects by remaining in contact with the mucosal lining, allowing for prolonged medication exposure and easy rinsing, while avoiding surgical removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If oral or intravenous medication is used to treat chronic sinusitis, then the medication can reach the sinuses, but the drug concentration is insufficient and systemic side effects occur
Solution Approach 1:
A viscous composition serves as an intermediary vehicle to deliver medication directly to the sinus cavity. The composition includes a thickening agent that allows the medication to adhere to the sinus mucosa, ensuring sufficient local concentration without requiring high systemic levels that cause side effects.
Solution Approach 2:
The medication is delivered with localized quality control - the viscous composition ensures the drug remains at the site of action (sinus cavity) rather than distributing systemically. This localized delivery achieves high drug concentration where needed while minimizing exposure to other organs and tissues.
2Ease of operation
If nasal sprays are used for medication delivery, then the medication can reach the nasal cavity, but the large particle size prevents penetration into the sinuses
Solution Approach 1:
The invention changes the physical parameters of the medication delivery system by using a viscous composition with specific rheological properties. The thickening agent creates a gel-like consistency that allows the medication to be delivered as a controlled substance rather than aerosol particles, enabling penetration into sinus openings while maintaining ease of administration.
3Quantity of substance
If sinus irrigations are used for medication delivery, then the medication can be delivered to the sinuses, but up to 97% of the medicated irrigation is wasted rushing out
Solution Approach 1:
The invention changes the viscosity parameter of the medication vehicle by incorporating a thickening agent. This increased viscosity causes the medicated composition to adhere to the sinus mucosa rather than flowing out rapidly, dramatically reducing drug waste while maintaining effective medication delivery to the target site.
4Quantity of substance
If drug-eluting devices are left within the sinuses, then localized medication delivery is achieved, but they impede wound healing and interfere with debridement
Solution Approach 1:
The invention extracts the medication delivery function from a permanent implanted device and replaces it with a temporary viscous composition that can be easily removed or rinsed out. This allows localized medication delivery during the critical healing period without interfering with wound care procedures or debridement, as the composition does not remain attached to the sinus wall like drug-eluting devices.
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 viscous composition effectively delivers medications to the sinuses, reducing side effects and improving surgical outcomes by maintaining drug concentration at the site of action, promoting healing and reducing the risk of infections and wound complications.
Implementation Method 1

AI summary
A medication or combination of medications for the treatment of a disease involving the sinuses is incorporated into a sterile medical gel. The viscosity of the gel or the adhesion of the gel to the patient's sinus cavity allows the gel to be maintained in the cavity for a sufficient length of time for treatment of the affected area, thereby reducing the amount of wasted medication that would otherwise result from other topical methods. In one embodiment, the medicated gel comprises a sterile viscous gel having a viscosity sufficient to be maintained within a paranasal sinus cavity after insertion, and a medication dispersed in the sterile viscous gel.
