Cleaning Device for Ablated Tissue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During ablation procedures, previously treated tissue can impair subsequent ablation effectiveness if not properly removed from the treatment site, leading to diminished outcomes.
Innovation Solution
A method involving the use of a cleaning device attached to an instrument, such as an endoscope or ablation device, to physically remove ablated tissue through abrasion, scraping, or rubbing, ensuring the site is cleared before subsequent ablation procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ablation is performed without removing previously treated tissue, then the ablation procedure can be performed continuously, but the effectiveness of subsequent ablation is diminished due to adherent treated tissue remaining in the ablation zone
Solution Approach 1:
The cleaning device is deployed before subsequent ablation to remove previously treated tissue from the ablation zone. This preliminary cleaning action ensures that the tissue surface is free of adherent treated tissue, thereby maintaining ablation effectiveness while allowing continuous procedure performance.
Solution Approach 2:
A cleaning device serves as an intermediary element between ablation procedures. This device physically removes treated tissue debris and adherent tissue from the ablation zone, acting as a mediator that enables effective subsequent ablation without requiring complete procedure interruption.
2Reliability
If a cleaning device is added to remove ablated tissue, then ablation effectiveness is improved, but device complexity increases
Solution Approach 1:
The cleaning device is integrated with the ablation catheter system, combining cleaning and ablation functions into a unified device. The cleaning device can be advanced through the ablation catheter or attached to it, merging multiple functions into a single system rather than requiring separate independent devices.
Solution Approach 2:
The cleaning device is designed to perform multiple functions: it can remove adherent treated tissue, clear the ablation zone of debris, and prepare the tissue surface for subsequent ablation. This multi-functionality reduces the need for multiple specialized devices while maintaining ablation effectiveness.

AI summary
A method for providing therapy to tissue at a treatment site is performed by ablating tissue at the treatment site with an ablation device. Next, a cleaning device is attached to an instrument. The cleaning device attached to the instrument is used to remove ablated tissue at the treatment site. The cleaning device may also be used to remove debris from the treatment site prior to ablation or other therapeutic or diagnostic procedure.
