Description

Technical Field

[0001] The present invention relates to a cerclage application device provided with a position fixing device, and more particularly, to a cerclage application device provided with a position fixing device for fixing the position of a cerclage application device used in a heart valve or pacemaker implantation operation to prevent the movement of the cerclage application device after the operation, thereby keeping the application device at an accurate position so as to sustain the therapeutic effect and improve the stability of the operation. Background Art

[0002] The heart is composed of two atria and two ventricles, and is connected to four blood vessels, namely the aorta, vena cava, pulmonary artery, and pulmonary vein, to serve as a blood flow path.

[0003] The heart is divided into the right atrium and the right ventricle on one side and the left atrium and the left ventricle on the other side, based on the ventricular septum in the center of the heart. There is a tricuspid valve between the right atrium and the right ventricle, and there is a mitral valve between the left atrium and the left ventricle.

[0004] As the heart repeatedly contracts and relaxes, the heart pumps, causing blood to flow through the blood vessels. During systole, blood in the heart moves toward the blood vessels, and in the right side of the heart, blood moves from the right ventricle to the pulmonary artery, and in the left side of the heart, blood moves from the left ventricle to the aorta.

[0005] However, when the membrane between the atria and ventricles does not work properly, blood from the ventricles flows back during the heart's systole. When the tricuspid valve between the right atrium and the right ventricle does not work properly, causing blood from the right ventricle to flow back into the right atrium, this is called "tricuspid regurgitation," and when the mitral valve between the left atrium and the left ventricle does not work properly, causing blood from the left ventricle to flow back into the left atrium, this is called "mitral regurgitation."

[0006] Tricuspid regurgitation usually occurs in patients with mitral regurgitation, and patients with heart valve disease may develop atrial fibrillation, arrhythmia, heart failure, etc. as their heart function decreases, which can be treated by inserting a pacemaker into the body.

[0007] In this regard, the inventors have proposed a device for treating mitral regurgitation, tricuspid regurgitation, heart failure, etc. using a cerclage device. In more detail, a patent for a device for treating mitral regurgitation was applied for in Korean Registered Patent No. 10-1116867, Korean Registered Patent No. 10-1231140, Korean Registered Patent No. 10-1563172, Korean Registered Patent No. 10-1581021, and Korean Publication Patent No. 10-2013-0074823, a patent for a device for treating tricuspid regurgitation was applied for in Korean Registered Patent No. 10-1805679 and Korean Publication Patent No. 10-2015-0144568, and a patent for a device for locating the end of a pacemaker lead was applied for in Korean Registered Patent No. 10-2016-0011530 and Korean Publication Patent No. 10-2016-0020887.

[0008] The patent basically relates to a "cerclage device" comprising a coronary sinus tube inserted into the coronary sinus, a tricuspid valve tube across the tricuspid valve, and a cerclage wire. The "cerclage device" is a name given in the sense that a cerclage wire is inserted into the superior vein-coronary sinus-ventricular septum-right atrium-superior vein and connected like a circle in the body, the cerclage wire is inserted into the coronary vein tube and the tricuspid valve tube and forms a circle in the body, and both ends pass through the superior vein and are positioned outside the body.

[0009] In the "cerclage device", the coronary sinus tube and the tricuspid valve tube are combined with each other at the upper portion and separated from each other at the lower portion, and the separated portion is positioned at the entrance of the coronary sinus.

[0010] At this time, the "cerclage device" often moves after the operation due to the sliding of the coronary sinus tube toward the coronary sinus side, and the present invention is an invention to improve the "cerclage device" in order to solve this problem. Summary of the invention

[0051] The advantages and features of the present invention and methods of achieving them will become clear with reference to the embodiments described in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments described below, but can be implemented in a variety of different forms, but the present embodiment completes the disclosure of the present invention and is provided to fully inform the scope of the present invention to ordinary technicians in the technical field to which the present invention belongs, and the present invention is only defined by the scope of the claims.

[0052] The specific contents for implementing the present invention are described in detail below with reference to the accompanying drawings. Regardless of the accompanying drawings, the same reference numerals indicate the same constituent elements, and "and / or" includes each and all combinations of more than one of the mentioned items.

[0053] The terms used in this specification are used to illustrate the embodiments rather than to limit the present invention. In this specification, unless otherwise specifically mentioned in the context, the singular form also includes the plural form. The "comprise" and / or "comprising" used in the specification does not exclude the existence or addition of one or more other constituent elements other than the mentioned constituent elements.

[0054] Unless otherwise defined, all terms (including technical terms and scientific terms) used in this specification can be used as the meanings commonly understood by ordinary technicians in the technical field to which the present invention belongs. In addition, unless otherwise clearly defined differently, the terms defined in commonly used dictionaries should not be interpreted as idealized or overly formal.

[0055] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0056] Figure 1 It is a stereoscopic view of a cerclage device provided with a position fixing device according to the present invention.

[0057] Figure 2a is a photograph showing a surgical scene in which a cerclage device provided with a position fixing device according to the present invention is inserted into a heart, and Figure 2b is a perspective view showing the coronary sinus.

[0058] Reference Figure 1 2 , the cerclage device provided with a position fixing device according to the present invention comprises a cerclage wire 1 , a coronary sinus tube 10 , a tricuspid valve tube 20 , and a position fixing device 30 .

[0059] The cerclage wire 1 is a name given to the coronary sinus, ventricular septum, and tricuspid valve in the sense of being connected like a circle, and is inserted into the coronary sinus tube 10 and the tricuspid tube 20 to be connected as a whole like a circle as shown in the figure.

[0060] An arch 60 is formed at one side of the cerclage wire 1. The cerclage wire 1 is inserted into the coronary sinus, and the coronary artery is located below the coronary sinus. At this time, a considerable external pressure is applied to the coronary artery due to the cerclage wire 1, and the arch 60 is used to prevent this and protect the coronary artery.

[0061] The coronary sinus tube 10 has a through hole formed inside and its lower part is inserted into the coronary sinus to protect the coronary sinus. The coronary sinus tube 10 can be made of rubber material, flexible plastic material, etc., and uses a material with excellent flexibility and resilience that is highly flexible and can move according to the beating of the heart.

[0062] The tricuspid valve tube 20 has a through hole formed inside, and penetrates the space (orifice) generated by the incomplete closure of the tricuspid valve and reaches the ventricular septum. The tricuspid valve tube 20 can be made of rubber material, flexible plastic material, etc., and a material with excellent flexibility and resilience that is highly flexible and can move according to the beating of the heart is used.

[0063] The tricuspid valve tube 20 includes a blocking part 40 coupled to a side surface, and the blocking part 40 blocks a space generated by incomplete closure of the tricuspid valve, which may use a blocking film, a blocking balloon, etc. The blocking part 40 blocks the empty space of the tricuspid valve to treat tricuspid regurgitation.

[0064] The tricuspid valve tube 20 is provided with a stopper 50 at the lower end of the tricuspid valve tube 20 to prevent the end from penetrating into the ventricular septum. This makes the tricuspid valve tube 20 not close to the tricuspid valve but suspended in the air, thereby preventing the tricuspid valve from being damaged by the tricuspid valve tube 20.

[0065] The position fixing device 30 is joined to one side of the coronary sinus tube 10 or one side of the outer peripheral surface of the coronary sinus tube 10 , and more than one position fixing device 30 is joined to prevent the coronary sinus tube 10 from sliding or moving due to heartbeat.

[0066] Figure 2b It is a diagram for explaining the coronary sinus in more detail. The inner wall of the coronary sinus is formed thicker than the outer wall. The position fixing device 30 is fixed to the inner wall of the coronary sinus, rather than to the outer wall of the coronary sinus which is thinner than the inner wall of the coronary sinus, thereby minimizing damage to the coronary sinus.

[0067] In Figures 3 to Figure 8 The position fixing device 30 is described in more detail in FIG.

[0068] In addition, the cerclage device provided with a position fixing device according to the present invention may include a defibrillator lead (not shown) inserted into the coronary sinus tube 10 or the tricuspid valve tube 20 to treat atrial fibrillation, or a pacemaker lead (not shown) having its terminal end inserted into the His bundle (His) to apply electrical stimulation to the heart.

[0069] 3 is a perspective view of a position fixing device according to a preferred first embodiment of the present invention, FIG. 3( a ) is a perspective view when the position fixing device is unfolded, and FIG. 3( b ) is a perspective view when the position fixing device is combined.

[0070] When the position fixing device 30 according to the preferred first embodiment of the present invention is described in more detail with reference to FIG. 3 , the position fixing device 30 includes a combining portion 32 and a fixing portion 34 .

[0071] The coupling portion 32 surrounds the coronary sinus tube 10 in a quadrilateral shape. The coupling portion 32 includes a protruding portion 32-1 protrudingly formed to extend from one end of the coupling portion 32 in the left-right direction, a first recessed portion 32-2 recessed from the other end of the coupling portion 32 in the left-right direction toward one end and formed corresponding to the formation of the protruding portion 32-1, and a second recessed portion 32-3 recessed from the lower end of the coupling portion 32 toward the upper end.

[0072] The coupling part 32 is coupled to surround the outer peripheral surface of the coronary sinus tube 10 in a state where the protrusion 32-1 is inserted into the first recessed part 32-2, and has an overall annular shape after coupling. When the coupling part 32 is coupled to the coronary sinus tube 10, an adhesive substance such as an adhesive that is harmless to the human body is applied to perform the bonding.

[0073] Both ends in the left-right direction of the coupling portion 32 formed with the protruding portion 32 - 1 and the first recessed portion 32 - 2 are preferably coupled to positions adjacent to the outer wall of the coronary sinus.

[0074] The position fixing device 30 includes a plurality of fixing parts 34 extending from the upper end of the second recessed part 32-3 and tilted at a predetermined angle toward the tricuspid valve tube so as to be easily inserted into the inner wall of the coronary sinus and easily detached from the tricuspid valve tube. The fixing part 34 has one end adjacent to the upper surface of the second recessed part 32-3 and the other end protruding toward the tricuspid valve tube 20, and has a quadrilateral shape, and the length in the width direction is formed to be longer as it moves from one end to the other, and the corners are formed to be rounded without sharp corners.

[0075] In more detail, the fixing portion 34 is positioned to be adjacent to the inner wall of the coronary sinus, so that when the coronary sinus tube 10 is inserted into the coronary sinus, the fixing portion 34 is fixed to the inner wall of the coronary sinus.

[0076] The inner wall of the coronary sinus is formed to be thicker than the outer wall, and the inner wall of the coronary sinus is not damaged even when the fixing portion 34 is fixed to the inner wall of the coronary sinus. However, when the fixing portion 34 is fixed to the outer wall of the coronary sinus, the outer wall of the coronary sinus may be torn and damaged due to its thin thickness.

[0077] Therefore, the position fixing device 30 according to the present invention is coupled to the coronary sinus tube 10 and the fixing portion 34 is fixed to the inner wall of the coronary sinus, thereby preventing the coronary sinus tube 10 from sliding or moving in position without causing damage to the coronary sinus.

[0078] Furthermore, since the corners on both sides are formed to be rounded, the position of the coronary sinus tube 10 can be fixed without causing deep damage to the inner wall of the coronary sinus even when it is fixed to the inner wall of the coronary sinus.

[0079] Even if the coupling portion 32 does not include the first recessed portion 32 - 2 and the protruding portion 32 - 1 , it can be implemented in an annular shape and may not include the second recessed portion 32 - 3 but may include the fixing portion 34 formed to extend directly from the lower end of the coupling portion 32 .

[0080] Figure 4 It is a perspective view of a position fixing device according to a preferred second embodiment of the present invention.

[0081] The position fixing device 30 according to the preferred second embodiment of the present invention comprises a coupling portion 32 and a fixing portion 34. The coupling portion 32 is the same as that illustrated in FIG. 3 , and in the position fixing device 30 according to the preferred second embodiment of the present invention, the number of fixing portions 34 coupled to the coupling portion 32 is different.

[0082] The position fixing device 30 according to the second embodiment is formed with a fixing portion 34 extending from the upper surface of the second recessed portion 32-3, and is inclined at a predetermined angle toward the tricuspid valve tube so as to be easily inserted when inserted into the inner wall of the coronary sinus and easily detached when detached. In more detail, one end of the fixing portion 34 is adjacent to the upper surface of the second recessed portion 32-3, and the other end protrudes toward the tricuspid valve tube, forming a quadrilateral shape, and the length in the width direction is formed to be longer as it moves from one end toward the other section, and the corners are formed to be rounded without sharp corners.

[0083] The fixing portion 34 of the position fixing device 30 according to the preferred second embodiment of the present invention is formed larger than the fixing portion 34 according to the first embodiment. Therefore, even if one fixing portion 34 is combined, an excellent fixing force is exhibited.

[0084] Figure 5 3 is a perspective view of a position fixing device according to a preferred third embodiment of the present invention. The position fixing device 30 according to the preferred third embodiment of the present invention includes a coupling portion 32 and a first fixing portion 37. The shapes of the coupling portion 32 and the first fixing portion 37 are the same as those of the coupling portion and the fixing portion illustrated in FIG. 3 , but the length of the coupling portion 32 in the thickness direction is formed to be longer than the length shown in FIG. 3 .

[0085] A quadrilateral groove 36 is formed at one side of the coupling portion 32 in a horizontal manner with the second recessed portion 32-3, and the position fixing device 30 includes a plurality of second fixing portions 38 formed to extend from the upper side of the groove 36 and bend at a predetermined angle toward the tricuspid valve tube 20. The second fixing portion 38 is formed identically to the fixing portion 34, and a plurality of the second fixing portions 38 are formed to be spaced apart from each other at predetermined intervals.

[0086] In the position fixing device 30 according to the preferred third embodiment of the present invention, since the first fixing portion 37 and the second fixing portion 38 are formed in one position fixing device 30, the fixing force can be improved even if one position fixing device 30 is fixed to the coronary sinus tube 10.

[0087] Figure 6 3 is a perspective view of a position fixing device according to a preferred fourth embodiment of the present invention. The position fixing device 30 according to the preferred fourth embodiment of the present invention includes a coupling portion 32 and a first fixing portion 37, and includes a quadrilateral groove 36 formed horizontally with the second recessed portion 32-3 at one side of the coupling portion 32, and includes a second fixing portion 38 formed to extend from the top of the groove 36 and bend toward the tricuspid valve tube 20 at a predetermined angle.

[0088] The joint portion 32 and the groove 36 are Figure 5 As described in the claims, the first fixing portion 37 includes a fixing portion 34 formed to extend from the upper end of the second recessed portion 32-3 and inclined at a predetermined angle toward the tricuspid valve tube so as to be easily inserted into the inner wall of the coronary sinus and easily detached.

[0089] In more detail, the shapes of the first fixing portion 37 and the second fixing portion 38 are similar to those in Figure 4 The shape of the fixing portion 34 of the preferred second embodiment of the present invention described in the figure is the same, and the first fixing portion 37 and the second fixing portion 38 are respectively formed to extend from the second recessed portion 32-3 and the groove 36, and protrude toward the tricuspid valve tube 20 at a predetermined angle, forming a quadrilateral shape, and the length in the width direction is formed to become longer as it moves from one end toward the other, and the corners are rounded without sharp corners.

[0090] In the position fixing device 30 according to the preferred fourth embodiment of the present invention, since two fixing parts 37 and 38 are formed in one position fixing device 30, the fixing force can be further improved even if only one position fixing device 30 is coupled to the coronary sinus tube 10.

[0091] Figure 73 is a side view of a position fixing device according to a preferred fifth embodiment of the present invention. The position fixing device 30 according to the fifth embodiment of the present invention includes a coupling portion 32 and a fixing portion 34. The coupling portion 32 includes a protrusion 32-1 and a first recessed portion 32-2 formed the same as those described in FIG. 3, but does not include a second recessed portion 32-3.

[0092] The fixing portion 34 is formed to protrude outward along the lower peripheral surface of the coupling portion 32 positioned to face the tricuspid valve tube 20. More specifically, the fixing portion 34 is formed to have a predetermined inclination from the upper end to the lower end so that the lower end is most protruding, and when the coronary sinus tube 10 is inserted into the coronary sinus, the lower end of the fixing portion 34 is hung on one side of the inner wall of the coronary sinus to play a role like a stopper to prevent the coronary sinus tube 10 from further sliding.

[0093] The coupling portion 32 may be formed with grooves at left and right sides where the fixing portion 34 is coupled, so that the coupling portion 32 is flexibly bent so as to be coupled to the coronary venous tube 10 .

[0094] Figure 8 3 is a perspective view of a position fixing device according to a preferred sixth embodiment of the present invention. The position fixing device 30 according to the sixth embodiment of the present invention includes a coupling portion 32 and a fixing portion 34. The coupling portion 32 includes a protrusion 32-1 and a first recessed portion 32-2 formed the same as those described in FIG. 3, but does not include a second recessed portion 32-3.

[0095] The fixing parts 34 are provided to the outer peripheral surface of the connecting part 32, and the fixing parts 34 are tapered and arranged in a plurality of columns and rows at one side of the connecting part 32 facing the tricuspid valve tube 20. The fixing parts 34 are shaped like micro needles, and more specifically, the size is less than 1 mm, and various micro needles such as cones, polygonal cones, and spirals can be applied.

[0096] In more detail, the fixing portion 34 is fixed to the inner wall of the coronary sinus when the cerclage wire 1 is pulled so that the position of the coronary sinus tube 10 is fixed, and when the tension of the cerclage wire 1 is released, it is easy to be removed from the inner wall of the coronary sinus without causing damage to the inner wall of the coronary sinus.

[0097] When briefly describing the method of applying the cerclage application device provided with the position fixing device according to the present invention, first, the cerclage application device is inserted into the body. At this time, the cerclage application device is configured to basically include a coronary sinus tube 10 and a tricuspid valve tube 20, and one or more position fixing devices 30 are combined at one side of the coronary sinus tube 10. In addition, the lower end of the tricuspid valve tube 20 may include a stopper 40, and the outer peripheral surface of the tricuspid valve tube 20 may include a blocking portion 50.

[0098] Then, the cerclage wire 1 is inserted into the superior vein-coronary sinus tube 10-ventricular septum-tricuspid valve tube 20, and then protrudes from the superior vein. At this time, the cerclage wire 1 may include an arch 60 at one side.

[0099] Then, when both ends of the cerclage wire 1 positioned in the superior vein are pulled, tension is applied to the cerclage wire 1, the coronary sinus tube 10 moves in a direction toward the inner wall of the coronary sinus and the position fixing device 30 is fixed to the inner wall of the coronary sinus.

[0100] Therefore, the cerclage treatment device is prevented from sliding or moving due to heartbeat, so that the stability of the treatment can be improved, and the device can be fixed and maintained at an accurate position in the body.

[0101] Although the embodiments of the present invention are described with reference to the accompanying drawings described above, it is understood by those skilled in the art that the present invention can be implemented in other specific forms without changing its technical ideas or essential features. Therefore, the embodiments described above should be understood as exemplary in all aspects, rather than restrictive.
