Definitions

  • the present invention relates to a heart valve stent, in particular a mitral heart valve stent, which can be used during preparation of an implantable biological mitral heart valve for surgical treatment in human heart disorders.
  • Polish patent PL 176273 Bl discloses a flexible stent for a biological mitral valve implant, having a supporting element with a flange, both covered with coating material.
  • Said supporting element forms a Cassini's oval shape in cross section.
  • Cylindrical surface of the supporting element has a flange in its atrial cordis part, and also has two twin arms with wavy formed edges, in particular sinusoidal, in its heart ventricular part.
  • Arched openings between the arms have their bottoms in the short axis of the stent, whereas radius of the openings differ from each other.
  • the arms of the stent are advantageously convergent in the heart ventricle direction. The convergent angle is not bigger than 7°.
  • the flange of the stent has trapezium - like shape in cross section, whereas the longer base of the trapezium is adjacent to the cylindrical supporting element along its circumference.
  • the arms have their top radius not longer than 1/8 of the length of the stent' s long axis.
  • Mitral heart valve provided from a donor is sewn into the ring of a stent, whereas its tendinous chords, which had been previously cut from muscles, are individually one by one attached to the arms of the stent.
  • the operation of fastening the chords to the arms of the stent absorbs plenty of time, and the final result depends mainly on manual skills of the person who prepares the heart valve. There is no possibility to sew a complete heart valve unit with portion of muscles into the stent.
  • the present invention is directed to creating a heart valve stent, in particular mitral heart valve stent, which would allow to sew complete heart valve unit with muscles in order to simplify the preparation of the implant.
  • single arm of the stent consists of a number of rods, said rods are separated by slots and are located along the length of the arm.
  • the outside end portions of the rods form the outline of the arm.
  • each of the rods has a plate at its end, which simplifies attaching the muscles.
  • the plate has an oval shape. This allows an easy covering with coating material and also prevents the coating material from tearing due to lack of sharp edges.
  • a central axis of each rod lays in a plane which goes through the central axis of the stent.
  • each rod is a straight line.
  • each rod has an curvilinear shape, with convexity directed outside to the central axis of the stent.
  • single arm of the stent consists of a number of rods, said rods having central axes mutual convergent.
  • the central axes of said rods are mutual convergent in the direction of the ring.
  • rods of an arm are set on a single shaft protruding from said ring.
  • the main advantage of the invention relates to the possibility of using a complete mitral heart valve unit with pieces of muscles. Due to the above during preparation of the heart valve its individual geometry is maintained. Additionally the arms formed of rods make the stent flexible, which allows the tendinous chords to work properly and prevents them from tearing. It is also possible to bend the rods in order to adapt the stent to individual shape and size of a mitral heart valve. Apart from that, the stent with arms formed of rods has better blood flow characteristic in comparison to a stent with solid arms. After flowing through the ring blood run between the rods, which makes preferred blood distribution in the vicinity of mitral heart valve.
  • Fig. 1 is a view of a stent with arms formed of parallel rods.
  • Fig. 2 shows a developed view of a part of a stent with an arm consisted of three parallel rods.
  • Fig. 3 is a developed view of a part of a stent with an arm consisted of three convergent rods.
  • Fig. 4 is a developed view of a piece of a stent with an arm consisted of three convergent rods protruding from a single shaft.
  • Fig. 5 shows a piece of a stent in longitudinal section through a curvilinear rod.
  • fig. 6 is a view in longitudinal section of a straight lined rod.
  • the mitral heart valve stent is formed as an oval ring 1 with two arms 2.
  • Each of the two arms 2 is created by three rods 3 located along the length of the arms 2, said rods separated by slots 4.
  • Rods 3 of the arms 2 create a generator of a spatial figure, and said generator is convergent in opposite direction to said ring 1.
  • central axes 0 of the rods 3 are located inside the plane going through the central axei 0 ⁇ of the stent ( fig. 5 ). They also may be formed as straight lines ( fig.6 ).
  • said rods 3 have central axes 0 which are mutual convergent in direction of ring 1 (fig.3), whereas in particular embodiment rods 3 of each arm 2 are set on a shaft 7 which protrudes from ring 1. Said ring 1 as well as rods 5 are covered with coating material 8.

Abstract

La présente invention concerne une endoprothèse valvulaire cardiaque, en particulier mitrale, destinée à être utilisée lors de la préparation d'une implantation de valvule cardiaque biologique. L'endoprothèse est constituée d'un anneau implantable (1), formé de bras (2) comportant des tiges (3), ces tiges (3) étant séparées par des fentes (4). Des portions extérieures des tiges (3), avantageusement sous forme de plaques ovales (5), créent un contour (6) du bras (2). Les bras définissent (2) une ligne génératrice d'une figure tridimensionnelle qui converge en direction opposée du bras (1), alors que l'axe central (0) des tiges (3) peut être un segment droit ou courbe dont la convexité est dirigée vers l'extérieur par rapport à l'axe central (0) de l'endoprothèse.
