2 results about "Cardiac auricle" patented technology

Aspects of the present disclosure relate to devices, methods, and systems related to occlusion. In particular examples, devices, methods, and systems can include devices for placement in vessels, auricles, and body openings. The devices can include a unitary frame having a face portion including a central frame portion and a plurality of elongate members.

The application provides a heart tissue closure device. The heart tissue closure device comprises a first clamping arm, a second clamping arm and an elastic part. The first clamping arm comprises a first inner arm and a first outer arm arranged oppositely, and the first inner arm and the first outer arm are connected by a first elastic member. The second clamping arm comprises a second inner arm and a second outer arm arranged oppositely, and the second inner arm and the second outer arm are connected by a second elastic member. One end of the first clamping arm is rotationally connected with one end of the second clamping arm. The elastic part provides a clamping force for the first clamping arm and the second clamping arm. The heart tissue closure device provides a clamping force through the elastic part, and the clamping force is applied to the outer side of the first clamping arm and the second clamping arm, so as to drive the clamping arm to flatten the inner side of the auricle, realize the closure of the auricle, prevent the folding gap caused by the ligation of the auricle, and avoid the risk of residual blood flow.
