  • Patent number: 10624618
    Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.

  • Patent number: 10610356
    Abstract: An apparatus for use in the delivery of a prosthetic mitral valve may include an epicardial pad configured to engage an outside surface of a heart to secure a prosthetic heart valve in position within the heart. The epicardial pad defines a lumen configured to receive therethrough a tether extending from the prosthetic valve. The epicardial pad is movable between a first configuration in which the epicardial pad has a first outer perimeter and is configured to be disposed within a lumen of a delivery sheath and a second configuration in which the epicardial pad has a second outer perimeter greater than the first outer perimeter. The epicardial pad can be disposed against the outside surface of the heart when in the second configuration to secure the prosthetic valve and tether in a desired position within the heart.

  • Patent number: 10595858
    Abstract: A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.

  • Patent number: 10582920
    Abstract: Examples of a suture anchor (100) having a non-expandable body (105) and expendable cap (110) are described herein. In response to an axial insertion force that brings the non-expandable body and expendable cap together inside a bone hole, the expendable cap expands radially. This creates a radial force of expansion that advantageously augments an interference fit between the suture anchor and bone hole, which leads to higher fixation strength. Other examples include retention features that inhibit the expendable cap from returning back into its unexpanded state. This advantageously maintains the radial force of expansion against the surrounding pressure of the walls of the bone hole pressing back on the suture.

  • Patent number: 10575947
    Abstract: The present invention relates to a stent (10) for the positioning and anchoring of a valvular prosthesis (100) in an implantation site in the heart of a patient. Specifically, the present invention relates to an expandable stent for an endoprosthesis used in the treatment of a narrowing of a cardiac valve and/or a cardiac valve insufficiency. So as to ensure that no longitudinal displacement of a valvular prosthesis (100) fastened to a stent (10) will occur relative the stent (10) in the implanted state of the stent (10), even given the peristaltic motion of the heart, the stent (10) according to the invention comprises at least one fastening portion (11) via which the valvular prosthesis (100) is connectable to the stent (10). The stent (10) further comprises positioning arches (15) and retaining arches (16), whereby at least one positioning arch (15) is connected to at least one retaining arch (16) via a first connecting land (17).

  • Patent number: 10568736
    Abstract: Methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support member is positioned to at least partially surround the native leaflets of a valve. A locking member is used to couple both ends of the support member, forming a support band. An expandable prosthetic heart valve is delivered into the native heart valve and expanded while the expandable prosthetic valve is at least partially within the support band, thereby causing one or more of the native leaflets of the native heart valve to be frictionally secured between the support band and the expanded prosthetic heart valve.

  • Patent number: 10561437
    Abstract: Systems and methods for facilitating the removal of a tissue specimen from a patient are disclosed. The systems include a bag or pouch, a tissue cutter device, a support and a stabilizer. The tissue cutter device includes a passer, a wire, and a handle. The support is an elongated member. The passer is an elongated member configured to be coupled to the support and introduced as a temporary unit into the mouth of the bag or pouch in the patient's body holding the tissue specimen. The wire is attached to the passer. The temporary unit is configured to pass around the tissue specimen and out of the opening in the bag or pouch to carry the wire through that path so that a distal portion of the wire and a proximal portion of the wire are outside the patient's body. Those portions of the wire can be pulled to cut into the tissue specimen. The stabilizer holds the tissue specimen as the wire cuts into it.

  • Patent number: 10548711
    Abstract: A simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a socket in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the socket, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture is disclosed. Alternate embodiments of the anchor placement system and method of the present invention may forego tensioned sutures in favor of direct engagement with the soft tissue graft, whereby an end or a portion of the graft is trapped between an outer surface of the anchor and the boney surface of the wall of the socket such that friction force between the inserted portions of graft and socket maintains the position of graft relative to socket and bone. In either case, particularly preferred embodiments allow for the one-handed operation.
