Description

Изобретение относитс к медицине, а именно, к области кардиохирургии, и может быть использовано дл коррекции недостаточности митрального клапана. The invention relates to medicine, namely, to the field of cardiac surgery, and may be used to correct the mitral valve insufficiency.

Известен протез дл клапана сердца, состо щий из каркаса в виде жестокого кольца , повтор ющего форму основани клапана и оболочки 1Одной из частых причин митральной недостаточности вл етс расширение фиброз ного кольца клапана. Known prosthesis for a heart valve consisting of a frame in the form of rings ill repeated guide form the valve base and the shell 1Odnoy frequent causes of mitral insufficiency is the expansion valve fibrosis Nogo ring. Равномерное суживание основани клелана путем имплантации металлического кольца ликвидирует недостаточность кл 1пана. The uniform narrowing of the base klelana by implanting metal ring eliminates failure 1pana cells. Однако &то устройство имеет тот недостаток, что оно ригидно и жестко фиксирует фиброзное кольцо клапана в одном положении. However, & amp; the device has the disadvantage that it is rigidly and tightly fixes the valve annulus fibrosus in one position. Между тем известно, что в замыкательной функции кроме створок клапана и подклапачных структур большое значение имеет сближение во времени сие- толы фиброзной основы аортальной и муральной створок митрального клапана. Meanwhile, it is known that in the closing function of the valve leaflets apart and podklapachnyh structures is of great importance in the convergence time sie- Tola fibrous bases mural aortic and mitral valve. В результате клапан во врем систолы принимает вид шепи. As a result, the valve during systole becomes shepi. Жестка фиксаци фиброзного копьцакпапана искпючоег подобный механизм, Rigid fixation fibrous koptsakpapana iskpyuchoeg similar mechanism,

Кроме того, конструкци протеза не исключ прорезывание швов. In addition, the design of the prosthesis did not rule eruption of sutures.

Цель изобретени - обеспечение возможности сближени фибрознсй клапана во врем систолы и снижение риска прорезывани швов. The purpose of the invention - providing the possibility of convergence fibroznsy valve during systole and reducing the risk of eruption of sutures.

Поставленна цель досгагаетс тем, чуо часть каркаса клапана, определ юща конфигурацию кольца, повтор ющего форму основани клапана, выполнена жес1к.о&, а замы кающа часть каркаса выполнена гибкой, например, в виде пружины. This aim dosgagaets by Chuo portion of the valve frame, defining the configuration of a ring shape is repeated guide base valve is made zhes1k.o & amp ;, and the closure part repentieth frame is flexible, such as a spring.

На фиг. FIG. 1 изображен протез дл клапана сердца; 1 shows a prosthesis for a heart valve; на фиг. FIG. 2 - сечение по А-А на фиг. 2 - section A-A in Fig. 1; one; на фиг. FIG. 3 - сечение по Б-Б на фиг. 3 - a section along B-B in FIG. 1. one.

Протез состоит из каркаса в виде кольца 1, повтор ющего форму основани клапана и оболочки 2. Часть 3 каркаса, определ юща конфигурацию кольца, повтор ющего форму основани клапана, выполнена жест кой, а замыкающа часть 4 каркаса - гибкой , например, в виде пружины. The prosthesis consists of a frame 1 in the form of a ring by repeating the guide form the valve base and the shell 2. The frame portion 3, defining the configuration of the ring, form a base repeating guide valve is made gesture Coy, and lead-out part 4 carcass - flexible, for example in the form of a spring .

Таким образом гибка часть рротеза позвол е-т фиброзной основе створок совершать естественные колебательные движе- Thus the flexible portion allows rroteza e-t fibrous basis flaps make natural oscillatory motion

НИЯ aa счет прогибани гибкой час-ш, что поавои ет сердцу работать в услови х, блиашш к естественным. Nia aa account sagging flexible hour br that poavoi a heart to work under conditions bliashsh to natural.
