Definitions

  • the object of the present Invention is a prosthetic ring for heart surgery that includes significant innovations and advantages compared to other rings used for the same purpose .
  • the prosthetic ring of the invention simultaneously repairs two of the main causes of physio- pathological cardio valvular insufficiency of: the dilation of the natural ring and the prolapse of the valvular vela.
  • the heart is made up of four cavities that are connected to each other via some cardiac valves whose job is to allow the passage of blood in a single direction, not allowing the passage of blood in the opposite direction.
  • Aortic stenosis must presently be treated surgically by means of the use of a replacement with a valvular prosthesis.
  • mitral insufficiency causes secondary ischemia to cardiopathic ischemia from lesions of the coronary arteries or through a myocardial infarction, rheumatic illness, infectious endocarditis, cardiac traumas and congenital disease of the heart.
  • Another cardiac valve, the tricuspid valve can also suffer from illnesses of differing causes (rheumatic, degenerative, functional, congenital, infectious endocarditis, traumatic) and is also capable of surgical repair.
  • both the mitral valve and egually the tricuspid valve can suffer from a disease that brings about malfunction that is characterised by the reflow of blood from the ventricle to the auricle.
  • This lesion is called mitral insufficiency or regurgitation and/or tricuspid, in accordance with the malfunctioning valve.
  • the valvular insufficiency or regurgitation can be produced by multiple mechanism or lesions that overall causes the valve no to work properly and a part of the blood that the ventricle pumps returns to the auricle. This is because the valve does not completely close to a greater or lesser degree. This incomplete closure can be produced by differing mechanisms but the two most frequent mechanisms and that bring about the highest percentage regurgitation are:
  • the vela are not held on the closure plane but because of an excess of movement protrude or prolapse or are anomalously directed towards the auricle.
  • the space that remains between the valvular closure plane and the prolapse of the vela allows the anomalous passage (reflow) of blood towards the auricle bringing about valvular insufficiency and illness.
  • prosthetic rings of differing forms (without shape, pre-shaped) , of differing flexibilities (flexible, semi-rigid, rigid) and of differing contours (closed, open) .
  • the prosthetic rings aimed at the reconstruction of the mitral ring generally have a ⁇ D' shaped form, whilst the rings aimed at tricuspid reconstructions have a more or less ovoid form.
  • the prosthetic ring on its own does not solve the problem and surgeons need to carry out other repair techniques to the vela, the cords, the papillary muscles or the ventricle itself.
  • the key to the successful repair of the heart valves consists of a system that allows a surgical correction of the two causes involved in the valvular insufficiency or regurgitation, the dilation of the ring and the prolapse of one or several of the vela.
  • the prosthetic ring for heart surgery of this present registration solves the previously stated disadvantages, moreover, providing other advantages that will become clear from the description which is attached below.
  • the prosthetic ring of the invention simultaneously repairs two of the main causes of physio- pathological cardio valvular insufficiency of: the dilation of the natural ring and the prolapse of the valvular vela.
  • the prosthetic ring for heart surgery of the invention is particularly for the reconstruction of the mitral valve and the tricuspid valve, it is made up of a prosthetic ring of a flexible material, a closed and pre-formed contour, that when implanted carries out the anuloplasty or reduction of the dilated natural ring to its normal size, and is characterised because on the inside said ring has a net or mesh that is extended throughout the area defined by the perimeter of the ring and prevents the prolapse of one or several vela towards the auricular cavity, allowing the passage of blood from the auricle to the ventricle.
  • the stated net or mesh is interwoven in such a way that it holds itself in an immovable position during the cardiac cycle.
  • the tension of the net or mesh is small allowing the absorption of the inertial impact of the vela of the heart valve.
  • the net or mesh can be made with materials such as expanded polytetrafluorethylene or prolone®.
  • the prosthetic ring is a tubular structure of a textile nature that encloses a flexible tube that forces the ring to take a predetermined shape, which in general is X D' or kidney shaped, the shape that the cardiac valves have when they are closed.
  • the external tube is made out of a fabric material that allows the prosthetic ring to be connected to the natural ring by means of sutures, the passage of the needles with thread, which is connected to the diseased cardiac ring.
  • the prosthetic ring that has been developed can be fitted with a support that allows easy handling of same during the surgical procedure. Once the prosthetic ring is implanted in the diseased heart the said support can be released on cutting the sutures, linking device, that connect it to the support.
  • the prosthetic ring of the invention surgically corrects the main causes of insufficiency or regurgitation of the heart valves, especially the mitral valve and the tricuspid valve, completely correcting the pathological motives that cause the valvular insufficiency, the dilation of the valvular ring and the prolapse of the vela.
  • Figure 1 shows a schematic view of the prosthetic ring of the invention
  • Figure 2 shows a schematic view of the application of the above prosthetic ring
  • the prosthetic ring for heart surgery and particularly for the reconstruction of the mitral valve and the tricuspid valve is made up from a flexible prosthetic ring (1), closed and pre-formed, that once implanted carries out the anuloplasty or reduction of the natural ring (2) dilated to its natural size, and that internally has a net or mesh (3) that is extended throughout the area defined by the perimeter of the prosthetic ring (1) and that prevents the prolapse of one or several vela towards the cavity of the auricle, allowing the passage of blood from the auricle towards the ventricle.
  • the stated net or mesh (3) is interwoven in such a way that it keeps itself in an immovable position during the cardiac cycle.
  • the material of the net or mesh can be made with materials such as expanded polytetrafluorethylene or prolone®.
  • the tension of the net or mesh (3) has a predetermined value that allows the absorption of the inertial impact of the vela of the heart valve.
  • the prosthetic rung (1) is a tubular structure of a textile nature that encloses a flexible tube that forces the ring to take a predetermined shape, which in general is X D' or kidney shaped, the shape that the cardiac valves have when they are closed (not shown) .
  • the external tube is made out of a fabric material that allows the prosthetic ring to be connected to the natural ring (2) to be made by means of sutures, the passage of the needles with thread (4), which is connected to the diseased cardiac ring.
  • the prosthetic ring that has been developed can be fitted with a support that allows easy handling of same during the surgical operation. Once the prosthetic ring is implanted in the diseased heart the said support can be released by cutting the sutures, linking device, that connect it to the support (not shown) .
  • the prosthetic ring of the invention surgically corrects the main causes of insufficiency or regurgitation of the heart valves, especially the mitral valve and the tricuspid valve, completely correcting the pathological motives that cause the valvular insufficiency, the dilation of the valvular ring and the prolapse of the vela.

Abstract

L'invention concerne un anneau prothétique pour chirurgie cardiaque permettant, en particulier, de reconstruire la valvule mitrale et la valvule tricuspide. Ledit anneau prothétique (1) comprend un matériau souple, un contour fermé et préformé qui lorsqu'on l'implante effectue l'annuloplastie ou ramène l'anneau naturel (2) dilaté à sa taille normale, et un filet ou un treillis (3) placé à l'intérieur dudit anneau qui s'étend à travers une zone définie par le périmètre de l'anneau prothétique (1) et empêche le prolapsus d'une ou de plusieurs voile(s) vers l'oreillette, ce qui permet le passage du sang de l'oreillette au ventricule.
