Elastomeric Attachment for Implantable Device Deployment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical device deployment systems lack precise control and repositioning capabilities, making it difficult for clinicians to accurately place and secure implantable devices within bodily cavities, organs, and vessels during minimally invasive procedures.
Innovation Solution
A deployment system featuring an implantable medical device with elastomeric attachment features and a delivery device that includes a catheter and elongate element, allowing for controlled positioning and release of the device, enabling accurate placement and potential repositioning through a deployment actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded screw-type attachment is used to connect the delivery catheter to the implantable medical device, then the device can be securely attached and delivered, but the system lacks precise control and repositioning capabilities after deployment
Solution Approach 1:
The patent transitions from a static threaded attachment system to a dynamic control system using an elongate element that can be selectively engaged and disengaged from the implantable device. This allows the delivery catheter to maintain secure attachment during delivery while enabling precise control and repositioning capabilities after deployment through the deployment actuator.
Solution Approach 2:
The patent introduces a deployment actuator as an intermediary mechanism between the operator and the implantable device. This actuator controls the elongate element's engagement with the device, providing precise control and repositioning capabilities without requiring direct manual manipulation of the threaded attachment components.
2Measurement precision
If the delivery system allows temporary release and re-coupling for repositioning, then positioning accuracy can be improved, but the device complexity increases
Solution Approach 1:
The patent designs the delivery catheter system to perform multiple functions: secure attachment during delivery, controlled temporary release, repositioning capability, and final deployment. The elongate element and deployment actuator serve as multi-functional components that enable all these operations within a single integrated system, rather than requiring separate mechanisms for each function.
Solution Approach 2:
The implantable medical device includes self-expanding frame structure that can expand to a larger size after ejection from the delivery catheter. This self-expansion mechanism provides stable positioning and anchoring in the target location, reducing the need for complex external positioning mechanisms and simplifying the overall system while maintaining positioning accuracy.
