Annuloplasty Device Patents (Class 623/2.36)
  • Patent number: 7396364
    Abstract: Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner such as by applying energy percutaneously or external to the patient's body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices include a body member including a shape memory material, and an energy absorption enhancement material configured to absorb energy in response to an activation energy. The energy absorption enhancement material is in thermal communication with said shape memory material.

  • Publication number: 20080058924
    Abstract: A mitral annuloplasty ring that has a saddle shape with an upward bow in both an anterior segment and a posterior portion, with the upward bow being more pronounced in the anterior segment. The ring defines a closed ring body with a rounded isosceles triangular shape and the anterior segment along a long side. The posterior portion bulges outward to create a minor-major axis dimension ratio of between about 3.3:4 to 4:4. An inner ring body is made of a generally rigid material such as titanium that will substantially resist distortion when subjected to the stress imparted thereon after implantation in the mitral valve annulus of an operating human heart. The outward and upward posterior bow of the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, as seen with Barlow's syndrome for instance, in which the leaflets tend to be elongated or floppy.

  • Patent number: 7329280
    Abstract: Methods of implanting an annuloplasty ring to correct maladies of the mitral annulus that not only reshapes the annulus but also reconfigures the adjacent left ventricular muscle wall. A posterior portion of the ring rises or bows upward from adjacent sides to pull the posterior aspect of the native annulus farther up than its original, healthy shape. In doing so, the ring also pulls the ventricular wall upward which helps mitigate some of the effects of congestive heart failure. Further, one or both of the posterior and anterior portions of the ring may also bow inward. The methods include securing the annuloplasty ring with the anterior portion against the annulus anterior aspect and the posterior portion against the annulus posterior aspect so that the ring posterior portion elevates, and may also pull radially inward, the annulus posterior aspect and corrects the mitral regurgitation.

  • Patent number: 7314485
    Abstract: A mitral valve annulus reshaping device includes at least a portion that is formed of a biocompatible shape memory alloy SMA having a characteristic temperature, Af, that is preferably below body temperature. The device is constrained in an unstable martensite (UM) state while being introduced through a catheter that passes through the venous system and into the coronary sinus of the heart. The reshaping device is deployed adjacent to the mitral valve annulus of the heart as it is forced from the catheter. When released from the constraint of the catheter, the SMA of the device at least partially converts from the UM state to an austenitic state and attempts to change to a programmed shape that exerts a force on the adjacent tissue and modifies the shape of the annulus. The strain of the SMA can be varied when the device is within the coronary sinus.

  • Patent number: 7211110
    Abstract: A diagnostic device for determining the amount of change required in a coronary sinus to reduce valve regurgitation. The device includes a distal tube having a distal anchor at a distal end portion of the distal tube, a proximal tube having a proximal anchor at a distal end portion of the proximal tube, and an adjustor to move the distal tube relative to the proximal tube. The proximal tube and the distal tube together form a telescoping elongate body adapted to fit within the coronary sinus, and the device includes a scale to measure the movement of the distal anchor relative to the proximal anchor.

  • Patent number: 7166126
    Abstract: 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.

  • Patent number: 7160322
    Abstract: An apparatus helps improve operation of a heart valve. The apparatus includes an arcuate base portion having a central axis and a buttress extending from the base portion axially relative to the base portion. The buttress has a first surface and an opposite second surface. The first surface is dimensioned and configured to be engaged by a first leaflet of the heart valve when the apparatus is implanted in the heart valve. The second surface is dimensioned and configured to be engaged by a second leaflet of the heart valve when the apparatus is implanted in the heart valve. The buttress permits flow of blood adjacent both the first surface of the buttress and the second surface of the buttress when the first and second leaflets are not engaging the buttress.

  • Patent number: 7077861
    Abstract: A device for repairing a heart valve comprises an implantation instrument. The implantation instrument comprises a first support ring, and a second support ring connected to said first support ring to form a coiled configuration. The first support ring is configured to abut one side of the valve and the second support ring is configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween. The device further comprises an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly. The annuloplasty implant is connected to the implantation instrument for insertion to the annulus.

  • Patent number: 7063722
    Abstract: A method of implanting a resilient self-molding annuloplasty ring including stretching it to an expanded diameter and attaching it to a heart valve annulus, then permitting the ring to contract to reduce the diameter of the annulus. The ring may be positioned on an insertion device that maintains the ring in its expanded diameter while attaching to the annulus. The resilient self molding annuloplasty ring which may be enlarged prior to implantation to facilitate implantation within a dilated or otherwise incompetent valve annulus having sufficient contractive force to render a valve competent. The self molding annuloplasty ring of the invention may further comprise integral attachment devices to aid in the implantation process.

  • Patent number: 7044967
    Abstract: A device for treatment of mitral annulus dilatation comprises an elongate body having two states. In a first of these states the elongate body is insertable into the coronary sinus and has a shape adapting to the shape of the coronary sinus. When positioned in the coronary sinus, the elongate body 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.

  • Patent number: 7037334
    Abstract: The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing annuloplasty includes accessing a left ventricle of a heart to provide a discrete plication element to the left ventricle, and engaging the plication element to tissue near a mitral valve of the heart. Engaging the plication element includes causing the plication element to gather a portion of the tissue to create a plication. In one embodiment, accessing the left ventricle of the heart to provide the plication element includes accessing the left ventricle of the heart using a catheter arrangement.
