Three-dimensional distal coronary vein mapping catheter

Abstract

This utility model discloses a three-dimensional distal coronary vein mapping catheter, including a main mapping catheter and a secondary mapping catheter. The proximal end of the main mapping catheter is connected to an adjustable bending handle device, which includes a handle body, a turntable, and a pushing mechanism. The center extension line of the turntable is perpendicular to the axis of the main mapping catheter. The turntable is rotatably mounted on the handle body, and two bending wires are provided on the turntable and connected to the first mapping segment. The pushing mechanism is connected to the proximal end of the secondary mapping catheter. Compared with existing technologies, this method allows for the modeling of distal coronary veins, enabling more detailed detection of the patient's coronary vein information and facilitating rapid diagnosis. It achieves multiple functions with a single catheter, reducing the number of catheters required to enter the patient's body. Furthermore, the distal end of the main mapping catheter can be bent and deformed in two directions, facilitating access to the coronary sinus. This enhances surgical operability, reduces the burden on the patient, and saves surgical time.
