The frame includes an elongated base portion formed by two curved or chevron branches connected to two connection areas of the implant for connecting to the annulus of the mitral valve. The frame further includes a longitudinal hoop extending in a plane substantially perpendicular to the plane in which the elongated base portion extends. The membrane is flexible and extends from one branch to the other branch while passing around the longitudinal hoop. The membrane may be connected to the branches without being stretched between the branches and the hoop so that the membrane forms lateral portions on each side of the implant that are able to transition between an outwardly convex, concave shape, and an outwardly concave, recessed shape.

  • Patent number: 10603170
    Abstract: A membrane having at least one strip of a shape memory material and the at least one strip is sandwiched between a first layer and a second layer. A method for guiding bone regeneration which excludes the use of a tenting screw is also disclosed. The membrane may be useful for gradual displacing of the soft tissue covering bones. The gap developing between the bone and the displaced soft tissue may be filled with regenerated bone. The membrane allows the regenerated bone to form while the soft tissue heals. The membrane and method may be useful in dentistry for treating vertical bone defects. The membrane and method may also be useful for regenerating soft tissue between the bone and the displaced soft tissue.

  • Patent number: 10583008
    Abstract: Mitral valve implants and devices, kits and methods are provided for mitral valve repair. Devices comprise a body attachable onto the mitral valve annulus and a bridge connected to the body by two legs which are configured to support and position the bridge within a left ventricle (LV) of the patient when the device body is implanted, so that the legs and the bridge avoid contact with the LV walls, papillary muscles and chordae during operation of the heart. The bridge may be used to anchor valve leaflet tissue, provide support for leaflet re-modelling, possibly using external tissue, and/or anchor artificial chords used to modify and repair the operation of the mitral valve. Related medical procedures as well as kits and related utensils are also provided.

  • Patent number: 10575952
    Abstract: Dislodgment of a constricting cord from an annulus can be prevented by delivering the distal loop portion of the constricting cord to the annulus using a percutaneous delivery tool, and launching anchors into the annulus so as to affix the distal loop portion of the constricting cord to the annulus. The percutaneous delivery tool is withdrawn in a proximal direction after the anchors have been launched. A pushing member is pressed in a distal direction so that the pushing member holds a portion of the constricting cord against the annulus with enough pressure to prevent dislodgment of any of the anchors during the withdrawal of the percutaneous delivery tool.

  • Patent number: 10561423
    Abstract: A shunt device for creating a shunt in an atrial septum includes magnets coupled to inner loops of a coil comprising at least two inner loops and two outer loops, with a diameter of each of the inner loops being less than a diameter of the outer loops. The coil is made of a shape memory alloy (SMA) and is adapted to exert a compressive force upon layers of tissue caught between the inner loops of the coil. The magnets are adapted to provide additional compressive force to adjacent inner loops of the coil, thereby further causing the coil to cut through the layers of tissue and create a shunt. The diameter of the resultant shunt is less than the diameter of the outer loops, thereby preventing the outer two loops from passing through the created shunt. At least one end of the coil has a connection means for connecting with a delivery device.

  • Patent number: 10543089
    Abstract: A prosthetic remodeling annuloplasty ring for use in tricuspid or mitral valve repairs to provide support after annuloplasty surgery. The annuloplasty ring includes a relatively rigid core extending around an axis that is discontinuous to define two free ends. A suture-permeable interface surrounding the core includes floppy regions adjacent both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus, including at least one suture through each of the floppy regions to secure the free ends of the ring and minimize the risk of ring dehiscence, or pull through of the sutures through the annulus tissue. The floppy regions may project from each free end into the gap toward each other, be radially enlarged such as paddle-like extensions, or may comprise outwardly lateral extensions at the free ends of the core.

  • Patent number: 10531956
    Abstract: An apparatus for repairing a heart valve and methods of use thereof are provided. The apparatus includes a radially expandable body and a blood-permeable member attached to the body at a first end and having at least one cord at a second end. The length or tension of the at least one cord is adjustable when the apparatus is implanted in a heart such that that the extent of atrial displacement of the heart's mitral leaflets during ventricular contraction can be adjusted. To implant the apparatus in a heart, the apparatus is inserted into a retaining sheath and the retaining sheath is then inserted into the heart. The retaining sheath is retracted from the apparatus and the apparatus is positioned inside the heart. The length or tension of the at least one cord is adjusted to adjust the extent of atrial displacement of the heart's mitral leaflets during ventricular contraction.

  • Patent number: 10524911
    Abstract: An annuloplasty repair segment for heart valve annulus repair. In one embodiment a multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves. Cable allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. In addition, selective placement of point-welds or other such control points locally control other parameters such as the amount and direction of displacement as the ring undergoes external loading. Cable with well-placed control points result in a MIS annuloplasty ring with sufficient flexibility in the x-y plane to allow a surgeon to squeeze the ring into a small incision, such as for example 1 cm×1 cm, while maintaining structural rigidity under forces exerted on the implanted ring by the cardiac cycle and allowing for asymmetrical deflection to be designed into the product.

  • Patent number: 10517719
    Abstract: Apparatus includes a tube and an implant moveable at least in part through a lumen of the tube. The implant includes a longitudinal member and a locking mechanism coupled to the longitudinal member. The locking mechanism has (i) an unlocked state in which the locking mechanism is configured to facilitate adjustment of tension of the longitudinal member, and (ii) a locked state in which the locking mechanism is configured to restrict adjustment of the tension of the longitudinal member. A tool maintains the locking mechanism in the unlocked state via contact of the tool with the locking mechanism in the heart, and moves the locking mechanism into the locked state. The locking mechanism is disposed distally to the distal end of the tube while the longitudinal member is disposed entirely within the tube. Other applications are also described.
