This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,738.

Summary of the Inventive Concept

The present inventive concept relates to an improved coronary sinus catheter handle that enhances the stability, ergonomics, and safety of the catheter system, providing real-time feedback to the operator and reducing the risk of vessel damage.

Background and Problem Solved

The original patent disclosed a stabilized coronary sinus catheter system with a control handle for steerable catheters operable with one hand. However, the original design had limitations in terms of tactile feedback, distal tip deflection angle, and ergonomics. The present inventive concept addresses these limitations by introducing an integrated sensor, optimized distal tip deflection angle, and improved ergonomics.

Detailed Description of the Inventive Concept

The enhanced coronary sinus catheter handle comprises an integrated single-axis location sensor disposed at the distal tip, which provides real-time feedback to the operator. The handle also features a contoured grip designed to fit comfortably in the operator's hand, with an adjustable handle length to accommodate operators of varying hand sizes. Furthermore, the distal tip deflection actuator is optimized to reduce the risk of vessel damage, and the control interface is simplified to minimize operator error. The inventive concept also includes an automatic shut-off mechanism that disables the distal tip deflection actuator in response to excessive force or pressure, and a warning system that alerts the operator of potential vessel damage.

Novelty and Inventive Step

The present inventive concept introduces a novel combination of an integrated sensor, optimized distal tip deflection angle, and improved ergonomics, which provides a significant improvement over the original patent. The inventive concept's novelty lies in the integration of these features, which enhances the stability, safety, and usability of the coronary sinus catheter system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the type and location of the sensor, modifying the contoured grip design, or using different materials for the handle. Additionally, the inventive concept could be adapted for use in other medical procedures or applications.

Potential Commercial Applications and Market

The enhanced coronary sinus catheter handle has significant commercial potential in the medical device industry, particularly in the field of electrophysiology and cardiac procedures. The inventive concept's improved ergonomics, safety features, and real-time feedback capabilities make it an attractive solution for hospitals, clinics, and medical professionals.
