Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing invasive medical device assemblies with active transducers face challenges in ergonomic handling and electrical connection to a power source, as cabling through the needle lumen obstructs fluid flow and additional sub-assemblies complicate precise handling during procedures.
Innovation Solution
An invasive medical device assembly with a hub housing that integrates an embedded circuit for direct electrical connection via a coaxial cable, featuring ergonomic design with grip surfaces and a finger guide for improved control, and a transducer mounted externally to the device, allowing for precise positioning and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cabling is routed through the needle lumen to connect the transducer to a power source, then electrical connection is achieved, but the internal diameter of the needle is obstructed, preventing fluid/medicine from flowing freely
Solution Approach 1:
The patent divides the electrical connection system into separate components: the transducer remains integrated with the needle, while the power source and cabling are separated and connected externally through the hub housing. This segmentation eliminates the need to route cables through the needle lumen, preserving fluid flow while maintaining electrical connection reliability.
2Reliability
If additional electrical connection sub-assemblies are attached to the proximal end of the needle assembly, then electrical connection to the power source is achieved, but the user's ability to precisely handle the needle assembly is compromised
Solution Approach 1:
The patent merges the electrical connection components into a single integrated hub housing assembly that attaches to the needle at one location. The hub housing consolidates the power source, cabling connection, and transducer interface into a unified structure, eliminating multiple separate sub-assemblies that would interfere with handling precision while maintaining reliable electrical connection.
3Reliability
If the power source is connected to the needle at the proximal end, then electrical connection is achieved, but extraneous sub-assemblies get in the way of precise handling during patient procedure
Solution Approach 1:
The patent extracts the power source and bulky connection sub-assemblies from the proximal end of the needle assembly and relocates them to a separate hub housing that attaches externally. This extraction removes the interfering components from the handling path while maintaining electrical connection through the integrated hub design.

AI summary
An invasive medical device assembly includes an invasive medical device and a hub housing configured to surround a portion of the invasive medical device. The invasive medical device may be a needle or other invasive medical device, and the hub housing may be configured to surround a hub of the invasive medical device. In one aspect, the invasive medical device may include a transducer. The hub housing can include at least one integrated circuit embedded therein that is configured to contact the external surface of the needle to electrically connect the transducer to a power source. The hub housing can be configured to provide an ergonomic handle for a user.
