Single Electrode Assembly for Synchronized Cardiac Pacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual chamber pacemaker devices require multiple electrode assemblies for synchronous pacing, which can lead to interference with the tricuspid valve, increased device complexity, and potential complications, while there is a need for improved electrode assembly configurations and interventional delivery systems.
Innovation Solution
A single electrode assembly is implanted in the septal wall of the heart to provide atrial synchronized left ventricular pacing, reducing hardware bulk and complications, and allowing for trans-septal pacing to stimulate both left and right branches of the Purkinje fibers for bi-ventricular stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electrode assemblies are used for synchronous pacing, then pacing coverage is improved, but device complexity and interference with the tricuspid valve increase
Solution Approach 1:
The patent combines multiple electrode functions into a single electrode assembly that can provide both atrial and ventricular pacing capabilities. The assembly includes electrodes positioned to stimulate both the atrium and ventricle through a single lead, eliminating the need for separate electrode assemblies and reducing device complexity while maintaining comprehensive pacing coverage
Solution Approach 2:
The single electrode assembly is designed with multi-functional electrodes that can perform multiple pacing functions. The assembly includes electrodes that can pace the atrium, ventricle, or both simultaneously, providing universal pacing capability through a single device that replaces multiple specialized electrode assemblies
2Reliability
If multiple electrode assemblies are used for synchronous pacing, then pacing coverage is improved, but potential complications increase
Solution Approach 1:
By merging multiple electrode assemblies into a single assembly, the patent reduces the number of implantation sites and leads required, thereby reducing potential sources of complications such as lead dislodgement, infection, and interference with cardiac valves while maintaining comprehensive pacing coverage
3Reliability
If conventional dual chamber pacemaker devices are used, then synchronous pacing is achieved, but hardware bulk and device complexity increase
Solution Approach 1:
The patent merges the functionality of separate atrial and ventricular electrode assemblies into a single integrated electrode assembly. This consolidation reduces hardware bulk by eliminating redundant leads and connectors while maintaining the ability to provide synchronous atrial and ventricular pacing through strategically positioned electrodes within the single assembly

AI summary
A method, system and device for implanting an electrode assembly of an implantable medical device in a patient's heart. Positioning one or more radiopaque markers in a coronary sinus of the patient's heart. Positioning, by using the one or more positioned radiopaque markers as a fluoroscopic visual reference, a distal tip of a delivery catheter within a right atrium of the patient's heart so that a distal opening of a lumen of the catheter is against a septal wall of the heart at a location between the ostium of the coronary sinus and the A-V nodal area of the right atrium, and so that the tip of the catheter is generally directed toward a left ventricle of the patient's heart. Advancing the electrode assembly through the lumen of the catheter and into the septal wall.
