Definitions

  • the invention relates to a mitral valve reconstruction ring.
  • Mitral valve reconstruction rings are used in cardiac surgery in the presence of mitral regurgitation or mitral regurgitation.
  • this object is achieved by a design with two curved brackets and two struts connecting them to one another, the struts being made of a material which allows the struts to be shortened to shorten them.
  • the material of the struts is chosen so that the shortening of the struts caused by the cranking is permanent, but the struts themselves are flexible.
  • the struts can also be attached in an articulated manner to the brackets in order to enable them to tilt relative to the bracket.
  • one bracket is curved more than the other bracket.
  • An embodiment is particularly preferred in which the struts extend at an angle to one another between the brackets.
  • the mitral valve reconstruction ring shown in Fig. 1 consists of two curved brackets 10, 12 and two struts 14, 16 connecting them together.
  • One bracket 10 is more curved than the other bracket 12, the struts 14, 16 do not extend in the embodiment shown parallel but form an angle to each other.
  • the bracket is covered with a fabric that allows the mitral valve reconstruction ring to be sewn onto the ostium of the mitral valve.
  • the struts 14, 16, as shown in FIG. 3 are cranked using suitable pliers, as a result of which the distance between the brackets 10, 12 is shortened . Since the depth of the cranking of the struts which can be seen in FIG. 3 determines the extent of the shortening of the distance between the two brackets 10, 12, an intraoperative adaptation to the respective conditions can take place.

Abstract

L'invention concerne un anneau de reconstruction des valvules mitrales. Cet anneau est composé de deux arceaux (10, 12) reliés par deux segments (14, 16). Les segments (14, 16) sont réalisés dans un matériau autorisant leur coudage et donc une réduction de leur longueur.
