Abstract: An atrial isolator comprising two tubular members, two lumens, drainage ports, and expandable occluders. The expandable occluders are adapted to engage an opening of the superior vena cava into the right atrium or the inferior vena cava and right tricuspid valve into the right atrium. The second tubular member is inserted into the lumen of the first tubular member to provide a displacement between the first expandable occluder and the second expandable occluder which is adjustable. A cardioplegia port is located between the two expandable occluders and in communication with a cardioplegic lumen. Methods of using such an atrial isolator are also disclosed, particularly to provide circulatory isolation of the heart and coronary blood vessels, and cardioplegia delivery.

Abstract: A suture-free clamp for sealing body tissue during introduction of medical devices, such as a cannula, aspirator, stent, endoscope, and pressure monitor. The clamp may be used in a patient's vascular tissues, such as the right atrium and the aorta. The clamp comprises a generally cone-shaped housing which includes a lumen for receiving a medical device, and a collar having a central opening for passage of a medical device, the collar connected to a proximal end of the housing by a plurality of struts. The proximal end of the housing and the collar each has an annular surface. The two surfaces are opposed, and are operable to clamp tissue therebetween, and to thereafter release the tissue by releasing the clamp. Methods are also disclosed for using the suture-free clamp for sealing body tissues during introduction of a medical device.
