  • RVOT wire capturing (RWC) system in mitral valve cerclage annuloplasty
    Patent number: 11207183
    Abstract: A mitral cerclage annuloplasty apparatus includes a catheter with a blocking member and a capturing member. The blocking member is in the shape of a pigtail or a balloon, and is configured on the distal portion of the catheter preventing the catheter from traversing through an unsafe zone thereby enabling the catheter to pass through the safe zone. This prevents damage to critical cardiac tissues. The capturing member is adapted for pulling out a RVOT cerclage wire into the IVC, and comprises of an expandable and collapsible mesh so that the RVOT cerclage wire is captured and directed into the IVC through the safe zone. Thus the RVOT cerclage wire is passed through the RV without damaging the heart tissue forming a complete circle around the mitral valvular annulus.

  • Bicuspid valve prosthesis, tricuspid valve prosthesis, and stent therefor
    Patent number: 11185410
    Abstract: A mitral valve prosthesis, a tricuspid valve prosthesis and a stent thereof. The stent is configured to support the heart valves of the mitral valve prosthesis and has a contracted configuration for delivery and an expanded configuration for deployment. The stent comprises, along its axial direction, an inflow section, a transition section and an outflow section, and the transition section is connected to the inflow section at one end and to the outflow section at the other end. When in the expanded configuration, the inflow section is located upstream of the outflow section with respect to the blood flow direction. The inflow section is less radially rigid than the outflow section and/or the transition section. Due to such a small radial rigidity, the inflow section can well adapt itself to the anatomy of the native mitral annulus.

  • Suture length adjustment for minimally invasive heart valve repair
    Patent number: 11173030
    Abstract: Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.

  • Tube stent
    Patent number: 11173059
    Abstract: A tube stent includes a first tube body. The first tube body includes a first section, a second section, and a transition section located between the first section and the second section. One end of the transition section is connected to the first section, and the other end is connected to the second section. The shortening rate of the first section and the shortening rate of the second section are smaller than the shortening rate of the transition section. By using the tube stent, the pulsations of aortas are buffered by the transition section, so that vibration deformations of the tube stent are confined to the first section and the transition section, and accordingly the relative stability of the second section and branch blood vessels can be ensured, and the stimulations to walls of the branch blood vessels can be reduced.
