Description

{A device for the treatment of position-adjustable tricuspid regurgitation}

The present invention relates to a device for a tricuspid valve reflux treatment with adjustable position, and more specifically, it is used to confirm whether right ventricular dysfunction may occur when treating tricuspid valve reflux by surgery or other permanent treatment. It relates to a device for tricuspid regurgitation procedure that can be positioned and removed after a certain period of time so that it can be inserted into the tricuspid valve obliquely to obstruct the empty space caused by the incomplete closing phenomenon of the tricuspid valve depending on the patient. .

The heart consists of four spaces: the left atrium, the left ventricle, the right atrium, and the right ventricle, and is connected to the aorta, large vein, pulmonary artery, and pulmonary vein. A valve exists between the ventricle and the atrium, and the valve between the left atrium and the left ventricle is called the mitral valve, and the valve between the right atrium and the right ventricle is called the tricuspid valve.

The heart repeats contraction and relaxation, and blood flows. During the systolic phase of the heart, blood in the heart moves to the blood vessels. Blood moves from the right ventricle to the pulmonary artery and from the left ventricle to the aorta.

However, if the valve does not work properly, blood flow, which must flow into the blood vessels back to the atrium, occurs when the heart contracts.

Tricuspid regurgitation is also called tricuspid regurgitation. Tricuspid regurgitation is a lesion of the tricuspid valve that does not close completely when the tricuspid valve needs to be closed, resulting in an orifice, and when the right ventricle contracts, some of the blood that needs to go from the right ventricle to the pulmonary artery flows back into the right atrium. Say the symptoms.

Conventional methods for treating tricuspid regurgitation include surgically correcting the patient by opening the chest and cutting the heart. In order to improve this in a very invasive manner, the tricuspid valve reflux treatment apparatus was developed in US Patent No. 8486136 B2, US Patent No. 7854762 B2, and US Patent No. 9474605 B2. The tricuspid valve reflux treatment devices are inserted into the relative vein-tricuspid valve-the right ventricle to block the empty space of the tricuspid valve to treat tricuspid reflux. In the tricuspid regurgitation procedures, an anchor installed at one end is fixed to the ventricle, and the other end is fixed to the outside of the heart through a relative vein. Therefore, the blocking part of the conventional patents has a disadvantage that it is penetrated in a vertical (longitudinal orientation) to the center of the tricuspid valve orifice and is located in an unstable state floating in the heart.

In addition, the tricuspid valve reflux treatment device is permanently inserted into a patient's body to treat tricuspid reflux, and when tricuspid valve reflux treatment is performed using a permanent tricuspid reflux treatment device, sudden flow of blood flow from the right ventricle to the pulmonary artery Due to a significant increase, overload of the right ventricle may occur, and a problem in which symptoms of right ventricular dysfunction may occur.

Therefore, there is a need for a surgical instrument for identifying problems that occur to a patient in advance during a tricuspid reflux procedure by being temporarily inserted into the body before the tricuspid reflux procedure using a permanently inserted tricuspid reflux procedure.
