Publication number: 20130126012Abstract: 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.Type: ApplicationFiled: January 17, 2013Publication date: May 23, 2013Applicant: Cardiodex Ltd.Inventor: Cardiodex Ltd.

Patent number: 8435236Abstract: An apparatus for treating varicose veins includes a catheter (20) where the distal end is placed within a varicose vein and the proximal portion remains outside the body of the subject. A heating element (22) heats the vein. A cooling element (62) can be applied to an external surface of the skin above the vicinity of the heating element. A control unit (26) can drive the heating element to apply heat to the vein simultaneously. Alternatively, the control unit can apply a current to the heating element to resistively heat a resistive element. A method for treating a varicose vein includes inserting the elongated heating element into the vein, and driving the heating element to apply heat to the segment of vein simultaneously from the entire active heating portion.Type: GrantFiled: November 21, 2005Date of Patent: May 7, 2013Assignee: CardioDex, Ltd.Inventors: Noam Mizrahi, Shimon Eckhouse, Alon Getz, Aharon Cohen, Fabian Izhack, Eran Levit
