Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting the appropriate catheter configuration for a patient's anatomy during medical procedures is challenging due to anatomical differences, leading to repeated insertions and removals, which can result in injuries, embolization, mechanical injuries, and increased adverse event rates.
Innovation Solution
A system utilizing pre-procedure 3D imaging with MRI or CT scans to reconstruct patient anatomy, comparing it with various catheter configurations to select the optimal catheter configuration for successful navigation through the patient's anatomy, employing a central processing unit for automatic or manual analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple catheters are inserted to accommodate patient anatomy, then the appropriate catheter configuration can be found, but the risk of injury and adverse events increases
Solution Approach 1:
The system performs preliminary 3D imaging and virtual catheter testing before the actual procedure to identify the optimal catheter configuration in advance. This preliminary action allows the clinician to select the correct catheter before insertion, avoiding multiple trial insertions and reducing the risk of injury to the patient.
Solution Approach 2:
The system creates a 3D copy or virtual model of the patient's anatomy from imaging data and tests catheter configurations in this virtual environment. This copying approach allows virtual simulation of catheter navigation through the patient's specific anatomical structures without actual physical insertion, enabling safe pre-procedure planning.
2Reliability
If multiple catheters are inserted to accommodate patient anatomy, then the appropriate catheter configuration can be found, but time and resources are wasted

3Reliability
If multiple catheters are inserted to accommodate patient anatomy, then the appropriate catheter configuration can be found, but the complexity of the procedure increases
Solution Approach 1:
The system introduces a 3D imaging and virtual simulation intermediary between the clinician's knowledge and the actual catheter selection. This intermediary processes anatomical data and simulates catheter performance to objectively determine the optimal configuration, reducing the complexity of the decision-making process and eliminating the need for multiple trial insertions.
