Abstract
Systems, apparatuses and methods are provided for use in closing punctures in vessel walls. An apparatus may have various combinations of an anchoring device, a positioning device and a heating element for closing a puncture within a vessel wall. An anchoring device may be a balloon, an expansible cage, a wire operated T-anchor, and/or a floating anchor. A positioning device may be a balloon, a sponge, and/or an expansible cage. A heating element may be flexible or rigid and preferably provides heat to target tissue through conduction and convection. A heating element may be flat-ended or dome-shaped. The heating element and anchoring device may be positioned a fixed distance apart to sandwich tissue between the heating element and the anchoring device. The heating element may operate in multiple stages. An initial stage may non-permanently adhere the heating element to the tissue and the subsequent stage may close the puncture.
