摘要：
1. An electrophysiological catheter having: an elongated catheter body； a control handle located proximally relative to the catheter body； an end electrode located distally relative to the catheter body, the end electrode having a sheath and a support element fastened by welding, while welding has at least one Roller weld and at least one weld with penetration of the base metal. 2. The catheter according to claim 1, wherein at least one roller weld and at least one weld with penetration of the base metal are overlapped along an axis. The catheter according to claim 1, wherein at least one roller weld and at least one weld with penetration of the base metal are overlapped along the circumference. The catheter according to claim 1, wherein the sheath has a rim and the support structure has a circular protrusion, the end electrode having a connecting seam where the rim and the circular protrusion are in contact with each other, and welding is carried out at least partially around the connecting seam. . The catheter according to claim 1, wherein the weld includes a butt weld between the rim and the circular protrusion. The catheter according to claim 1, wherein the weld with penetration of the base metal includes through penetration, which passes along the wall of the rim and part of the supporting structure. The catheter according to claim 1, wherein the weld includes at least one segment of a roller weld extending circumferentially around the end electrode. The catheter according to claim 1, wherein the metal penetration weld includes at least one metal penetration weld segment extending along1. Электрофизиологический катетер, имеющий:удлиненный корпус катетера；рукоятку управления, расположенную проксимально относительно корпуса катетера；концевой электрод, расположенный дистально относительно корпуса катетера, причем концевой электрод имеет оболочку и опорный элемент, скрепленные сваркой, при этом, сварка имеет по меньшей мере один роликовый сварной шов и по меньшей м
