Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating chronic sinusitis, such as FESS and Balloon Sinuplasty, lack effective irrigation solutions during procedures, which is necessary for improved drainage and ventilation of sinuses.
Innovation Solution
A medical device with adjacent inflation and irrigation lumens, featuring an inflatable balloon and an irrigation tip with radially facing openings, designed for sinus dilation and irrigation, allowing for efficient fluid delivery and suctioning during and after dilation procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If FESS or Balloon Sinuplasty procedure is performed, then sinus drainage and ventilation is improved, but irrigation capability during the procedure is insufficient
Solution Approach 1:
The patent combines the dilation function (balloon catheter) and irrigation function (irrigation catheter) into a single integrated device. The irrigation lumen is positioned adjacent to the balloon, allowing irrigation fluid to be delivered directly to the sinus ostium during the dilation procedure, thereby providing both drainage improvement and irrigation capability simultaneously.
Solution Approach 2:
The medical device performs multiple functions: it can dilate the sinus ostium using the inflatable balloon and simultaneously or subsequently irrigate the sinus cavity through the irrigation lumen and irrigation tip. This multi-functional design eliminates the need for separate irrigation procedures and enhances the versatility of the treatment system.
2Ease of manufacture
If separate irrigation catheter is used after dilation procedure, then irrigation can be performed, but the procedure requires additional steps and time
Solution Approach 1:
By integrating the irrigation lumen and irrigation tip into the same catheter system as the balloon dilator, the patent eliminates the need to introduce a separate irrigation catheter after dilation. The irrigation functionality is built-in, allowing the procedure to be completed in a single step without additional equipment introduction or procedural delays.
3Productivity
If irrigation tip with radially facing openings is used, then fluid delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The irrigation tip features radially facing openings that are strategically positioned to deliver irrigation fluid directly into the sinus cavity. This localized design enhancement at the tip region improves fluid delivery efficiency and distribution without requiring complex changes to the entire catheter structure. The radial openings create a spray pattern that enhances irrigation effectiveness while maintaining overall device simplicity.

AI summary
A medical device, and a system and packaged kit containing the medical device for the treatment of a sinus opening is described. The medical device comprises a proximal end, a distal end, and a shaft system having an inflation lumen and an irrigation lumen the proximal and. The shaft system has a proximal shaft section and a distal shaft section. An inflatable balloon is attached to the distal shaft section in a position that is proximal to said distal end. The irrigation tip is distal to the balloon on the distal shaft section and has a tip opening and one or more radially facing openings. A method for treating a sinus opening includes inserting a system that includes the medical device, a sinus guide catheter and a sinus guide element into a patient's anatomy, dilating the sinus opening and irrigating a target in the nasal anatomy.
