Solution Overview
Problem
Current ultrasound-based imaging systems for interventional cardiac electrophysiology procedures often require separate imaging probes and catheters, making it difficult for physicians to quickly and accurately determine tissue conditions during ablation therapy, and the images obtained can be challenging to interpret without additional imaging systems.
Innovation Solution
A combined ablation and ultrasound imaging probe with a housing having a proximal and distal tip section, featuring an ablation electrode and multiple ultrasonic imaging sensors configured to transmit acoustic waves in different directions, allowing for real-time visualization of anatomical structures and tissue characteristics during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate imaging probes and catheters are used, then imaging functionality is provided, but device complexity increases and ease of operation decreases
Solution Approach 1:
The patent combines multiple functions (ablation, imaging, mapping) into a single integrated probe. The housing contains both an ablation electrode and ultrasonic imaging sensors, eliminating the need for separate catheters and improving ease of operation during cardiac electrophysiology procedures.
Solution Approach 2:
The probe is designed to perform multiple functions simultaneously: ablation of cardiac tissue, ultrasonic imaging of anatomical structures, and electrophysiology mapping. This multi-functionality reduces the number of devices needed and simplifies the procedural workflow.
2Measurement precision
If multiple ultrasonic imaging sensors transmit acoustic waves in different directions, then visualization accuracy improves, but device complexity increases
Solution Approach 1:
The ultrasonic imaging capability is segmented into multiple sensors positioned at different locations and orientations within the housing. Each sensor transmits acoustic waves in a specific direction, and the combined data provides comprehensive three-dimensional visualization of anatomical structures and tissue characteristics.

AI summary
Devices and systems for ultrasonically imaging anatomical structures and performing ablation therapy within the body are disclosed. A combined ablation and ultrasound imaging probe includes a housing, an ablation electrode located on a distal tip section of the housing, and a number of ultrasonic imaging sensors configured for visualizing anatomical structures within the body. During an ablation procedure, the ultrasonic imaging sensors can be tasked to generate a number of ultrasonic images that can be displayed as a composite image on a display screen of a user interface.
