Transcatheter Intracorporeal Pump Segmentation for Minimally Invasive Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical circulatory support systems face challenges in accuracy and safety during transcatheter delivery due to anatomical complexities and limitations in device size and structure, leading to potential inefficiencies and risks such as infection, bleeding, and limited pump capacity and duration.
Innovation Solution
A transcatheter delivery system that allows for precise manipulation and guidance of intracorporeal devices from multiple angles and entry/exit points, using a catheter with a radial separation line and detachable components, enabling safe and accurate implantation across anatomical walls, particularly in the heart, with a focus on reducing pressure on the patient's anatomy and minimizing risks.

Engineering Contradiction Analysis
1Ease of operation
If percutaneous VAD is used with external pump, then minimally invasive access is achieved, but device size and complexity increase requiring patient immobilization
Solution Approach 1:
The device is divided into intracorporeal and extracorporeal components. The intracorporeal pump is implanted within the patient's body (intracorporeal), while the extracorporeal pump is positioned outside the body (extracorporeal). This segmentation allows the complex pumping function to be distributed, enabling minimal invasive access while reducing the size requirements for the external components.
Solution Approach 2:
The intracorporeal pump is nested within the patient's body cavity, specifically in the pericardial space, while the extracorporeal pump is positioned in a separate location. This nesting arrangement allows the device to leverage the patient's body space for housing the pump, thereby reducing the need for large external structures and enabling minimal invasive access.
2Ease of operation
If percutaneous VAD is used, then minimally invasive access is achieved, but risk of infection and bleeding increases
Solution Approach 1:
The device separates the pumping function into two segments: an intracorporeal pump implanted within the body cavity and an extracorporeal pump positioned outside. This segmentation eliminates the need for a permanent external driveline through the groin, thereby reducing the risk of infection and bleeding at the access site while maintaining minimal invasive access.
Solution Approach 2:
The extracorporeal pump is extracted from the body and positioned externally, eliminating the need for a permanent external driveline. This extraction removes the source of potential infection and bleeding risks associated with long-term external access, while the intracorporeal pump continues to provide the necessary pumping function.
3Power
If larger intracorporeal pumps are implanted surgically, then pump capacity is increased, but invasiveness and recovery time increase
Solution Approach 1:
The pumping function is segmented between an intracorporeal pump and an extracorporeal pump. The intracorporeal pump can be smaller since it only needs to provide partial support, while the extracorporeal pump provides additional pumping capacity. This segmentation allows for increased overall pump capacity without requiring a single large invasive implant.
Solution Approach 2:
The intracorporeal and extracorporeal pumps are merged into a single functional system. The intracorporeal pump is connected to the extracorporeal pump through a catheter, allowing the two pumps to work together to provide enhanced pumping capacity. This merging achieves the benefits of larger pump capacity while avoiding the need for a single large invasive implant.
4Ease of manufacture
If percutaneous access is used, then device insertion is simplified, but device size and structure are limited
Solution Approach 1:
The device is segmented into intracorporeal and extracorporeal components. The intracorporeal pump can have a simpler, more compact structure since it is implanted within the body cavity, while the extracorporeal pump handles the complexity of external connections and provides additional pumping capacity. This segmentation allows for simplified insertion while avoiding device size limitations.
Solution Approach 2:
The intracorporeal pump is nested within the patient's body cavity, allowing for a more compact and simpler design. The extracorporeal pump is positioned externally and handles the complexity of external connections. This nesting arrangement enables simplified device insertion while avoiding the size limitations imposed by percutaneous access requirements.
