Patent number: 10603022Abstract: A device for closing at least one opening leading to an anatomical cavity is delivered via a catheter positioned in a first opening leading to the anatomical cavity. An orientation control unit is positioned within the anatomical cavity. The orientation control unit defines an orientation of a portion of a tissue surface within the anatomical cavity that is skewed with respect to the first opening and orients a closure member of the device with the tissue surface. An occluding member and a constricting unit of the device are positioned within the anatomical cavity with the occluding member blocking a portion of an opening that is constricted by the constricting unit. An intermediate member of the device is positioned within the anatomical cavity and a closure unit employing at least one piercing element pierces through the intermediate member into a tissue wall surrounding the anatomical cavity.Type: GrantFiled: January 12, 2018Date of Patent: March 31, 2020Assignee: KARDIUM INC.Inventor: Samuel Lichtenstein

Publication number: 20090192539Abstract: An element is expanded in the left ventricle to isolate part of the left ventricle. The element has a generally convex outer surface and an apex which together define a desired geometry of the left ventricle. The isolated part of the wall of the left ventricle may be left so that the wall naturally forms around the element or the isolated portion of the ventricle may be evacuated and/or filled. The element may also be used to isolate part of the left ventricle containing a ventricular septal defect or other perforation or opening in the ventricular wall.Type: ApplicationFiled: April 6, 2009Publication date: July 30, 2009Inventor: Samuel Lichtenstein

Publication number: 20070198057Abstract: A device for closing holes tissue is delivered via a catheter to the inside of a body lumen such as a heart. An elastic barbed clip is expanded, pulled into the tissue and released, pulling the tissue with it. The operation is fully reversible.Type: ApplicationFiled: February 21, 2006Publication date: August 23, 2007Inventors: Daniel Gelbart, Samuel Lichtenstein

Publication number: 20070173924Abstract: A stent is capable of expanding both radially and axially during deployment. The stent can be balloon expandable or self expanding. In the balloon expandable version, circumferentially expandable structures are connected with folded links. When stent pulled axially, those links allow axial expansion without reducing radial expansion. A specially designed balloon, also capable of radial and axial expansion, is used to deploy the stent. A self-expanding version of this stent can be deployed without a balloon.Type: ApplicationFiled: January 23, 2006Publication date: July 26, 2007Inventors: Daniel Gelbart, Samuel Lichtenstein

Publication number: 20060253193Abstract: Making the volume of the arterial system increase elastically with blood pressure reduces high systolic blood pressure peaks and can also assist the pumping function of the heart by reducing load on the heart. This volumetric elasticity is achieved by the action of a spring controlling a volume. The spring can be implanted on the outside of the aorta and the volume is elastically controlled by squeezing the aorta or the spring can be installed inside an elongated elastic sealed vessel inserted into the aorta. Such a sealed vessel will respond to increase in blood pressure by reducing its volume, thus preventing the blood pressure from rising. When the latter method is used the device can be inserted into the aorta via a major artery without the need for major surgery. In both cases the device is powered by the blood pressure itself and requires no other energy source or control circuits.Type: ApplicationFiled: May 3, 2005Publication date: November 9, 2006Inventors: Samuel Lichtenstein, Daniel Gelbart

Publication number: 20060184242Abstract: A method and apparatus for treating mitral regurgitation by approximating the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve. The distal end of the device is inserted into the coronary sinus of the heart and the proximal end of the device rests within the right atrium along the tendon of Todaro and extends to at least the membranous septum of the tricuspid valve. Because the coronary sinus approximates the lateral (posterior) annulus of the mitral valve and the tendon of Todaro approximates the septal (anterior) annulus of the mitral valve, the device encircles approximately one half of the mitral valve annulus. The apparatus is then adapted to deform the underlying structures i.e. the septal annulus and lateral annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.Type: ApplicationFiled: April 10, 2006Publication date: August 17, 2006Inventor: Samuel Lichtenstein

Publication number: 20050149014Abstract: A medical device system comprising a guide catheter and a leaflet fastening applicator, the guide catheter having suitable dimensions for deployment and insertion percutaneously into a human heart in a vicinity of a heart valve, the leaflet fastening applicator having a size allowing insertion through the guide catheter and being capable of holding portions of opposing heart valve leaflets, wherein the fastening applicator comprises a pair of grasping-electrodes adapted for holding and engaging the portions of opposing heart valve leaflets together and for applying energy to fasten the portions, in which heart valve leaflets can be captured and securely fastened, thereby improving coaptation of the leaflets and improving competence of the valve.Type: ApplicationFiled: February 15, 2005Publication date: July 7, 2005Applicants: Evalve, Inc.Inventors: Wallace Hauck, Samuel Lichtenstein
