Publication number: 20090187241Abstract: The disclosure relates to frames suitable for prosthetic implantable valves, and methods of treatment with such frames, to regulate blood flow and to be compliant in percutaneous delivery and, upon implantation, configured to conform to the changing shape of the body vessel or vein. The frames include at least one anchoring member attached to a support member at one or more attachments, and a valve member, preferably a monocuspid valve leaflet, attached to the support member. Preferred frames include two anchoring members with the support member in between the anchoring members. The support member preferably has a semielliptical shape and extends diagonally to sealingly contact the wall of the body vessel.Type: ApplicationFiled: January 22, 2009Publication date: July 23, 2009Applicant: Cook IncorporatedInventor: Jeffry S. Melsheimer

Publication number: 20090182419Abstract: Among other things, a heart tissue support has gripping elements, each element having a free end that is sharp enough to penetrate heart tissue when pushed against the tissue, and a feature to resist withdrawal from the tissue after the sharp free end has penetrated the tissue. Among other things, the shape of a heart valve annulus is corrected in a catheter laboratory by orienting a tip of a catheter holding a heart tissue support that has gripping elements at the valve annulus, applying a radial force from the catheter against the annulus by opening a structure at the tip of the catheter, and while the structure is opened, forcing the support onto the annulus. Among other things, the shape of a heart valve annulus is corrected during a surgical procedure by pushing a heart tissue support that has gripping elements onto the annulus.Type: ApplicationFiled: March 19, 2009Publication date: July 16, 2009Applicant: Millipede LLCInventor: Steven F. Bolling

Publication number: 20090182418Abstract: A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.Type: ApplicationFiled: December 31, 2008Publication date: July 16, 2009Inventors: Jan Otto Solem, Per-Ola Kimblad, Randolf Von Oepen, Bodo Quint, Gerd Seibold, Kenneth J. Michlitsch, Suk-Woo Ha, Karl-Ludwig Eckert, Ib Joergensen, Stevan Nielsen

Publication number: 20090177266Abstract: Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.Type: ApplicationFiled: March 5, 2009Publication date: July 9, 2009Inventors: Ferolyn T.

Publication number: 20090177278Abstract: Valve repair apparatus and methods for ensuring proper coaptation and operation of the leaflets of a heart valve. Main aspects of the disclosure relate to devices including a support member configured for attachment to the heart valve annulus, a post extending from the support member away from the plane of the annulus and a connector coupled with the post and configured for attachment to at least one of the leaflets. The various embodiments may include a replacement heart valve connected with the support member for facilitating full replacement as opposed to near repair of an existing native heart valve. Various other devices include support structure and one or more posts connected to opposite sides of the support structure and extending from one side of the valve annulus to another to modify the shape of the annulus.Type: ApplicationFiled: March 13, 2009Publication date: July 9, 2009Inventor: Paul A. Spence

Publication number: 20090177277Abstract: Methods for reconfiguring an atrioventricular heart valve may use systems comprising a partial or complete fenestrated annuloplasty ring proportioned to reconfigure a heart valve that has become in some way incompetent, and a plurality of staples which may have pairs of legs that are sized and shaped for association with the ring at spaced locations along its length. These systems permit relative axial movement between the staples and the ring, whereby a patient's heart valve can be reconfigured in a manner that does not deter subtle shifting of the native valve components. Shape-memory alloy material staples may have legs with free ends that interlock following implantation. One alternative is to use flexible rings that will bend in the plane of the ring as the heart beats.Type: ApplicationFiled: February 2, 2009Publication date: July 9, 2009Inventor: Simcha MILO
