摘要： The application relates to a reaming type non-implanted atrial shunt device comprising a catheter component (2), a radio frequency component (1) disposed on an end of the catheter component (2) extending into a human body, and a radio frequency ablation instrument (4) disposed on the other end of the catheter component (2) and connected with the radio frequency component (1), wherein after the radio frequency component (1) extends into a puncture hole, the radio frequency ablation instrument (4) releases a radio frequency energy, and the radio frequency component (1) ablates a wall of the puncture hole. The radio frequency component (1) is delivered to the position of the puncture hole. When the radio frequency ablation instrument (4) releases energy, the radio frequency component (1) causes the hole wall tissue to generate heat and ablate the atrial septum at a target position to form a hole with fixed size, thereby achieving the purpose of creating a hole. Using radio frequency components (1) to create a hole through radio frequency make the hole not easy to reclose. The hole can effectively drain the left atrium blood into the right atrium, reduce pressure of the left atrium, thereby achieving the purpose of treatment.

摘要： The application relates to a heart valve clamp, comprises a fixed arm mechanism, a clamping arm mechanism, and a driving mechanism. The fixed arm mechanism comprises a fixed arm body and at least two fixed arms, extending outward from the fixed arm body, and integrally formed with the fixed arm body. The clamping arm mechanism comprises a clamping arm body connected to a bottom of the fixed arm body, and at least two clamping arms extending outward from the clamping arm bodies and integrally formed with the clamping arm body; and the driving mechanism comprises a second driving assembly that drives the fixed arm and the clamping arm to open or close. The fixed arm mechanism and the clamping arm mechanism of the entire heart valve clamp respectively forms an integral form, which can avoid the risk of the fixed arm or the clamping arm being disengaged, the stability of the whole structure is better. The fixed arm and the clamping arm clamp the valve leaflets under three-dimensional ultrasound and angiography navigation, so that the regurgitation area is reduced, which is capable of treating mitral or tricuspid regurgitation while keeping heat beating.
