Abstract: A vascular introducer sheath device comprising a tubular main shaft and a main hub attached to the proximal end of the main shaft. Attached to the proximal end of the main hub is a header hub, which has a first arm and a second arm. The header hub is attached to the main hub in a releasably locked configuration. As such, the header hub is functionally detachable from the main hub. The header hub and the main hub could together have a twist-on or snap-on mating mechanism. An example of such a mating mechanism is a male lock fitting on the header hub and a female lock fitting on the main hub. Further, there could be a side port on the main hub and a side port on the header hub, wherein the side ports for the main hub and header hub are oriented on a same plane when the header hub and the main hub are in locked configuration.

Abstract: A position-adjustable device for treatment of tricuspid regurgitation is proposed. The position-adjustable device for the treatment of tricuspid regurgitation is used to verify whether heart failure of the right ventricle may occur, and includes: a first catheter provided with a first lumen; a second catheter inserted into the first lumen and provided with a second lumen into which a guidewire is inserted; an adjusting part coupled to a lower side of the first catheter and the second catheter, wherein the adjusting part is provided with a first direction-adjusting device adjusting a direction of an upper end of the first catheter; and a blocking part coupled to an upper outer side surface of the second catheter, capable of adjusting a position according to a movement of the upper end of the first catheter, and obliquely penetrating and blocking the orifice formed by the incomplete closing of the tricuspid valve.
