Abstract

A device for implantation of an intravenous filter provided with a through opening comprises a hollow cable (4), a flexible rod (5) located inside the hollow of the cable (4) and a means for fixing the position of the rod (5) in relation to the body of the hollow cable (4). A locking mechanism consists of two loops (8) of a thread made of an elastic material, the ends of the loops (8) being secured to the body of the hollow cable (4), the length of the loops (8) exceeding that of the section of the hollow cable (4) between the point of attachment and the end of the hollow cable (4), including the thickness of the filter (1). The working end (7) of the rod (5) is shaped and has two diametrically opposite areas with a cylindrical lateral surface, the diameter of the working end (7) of rod (5), within the limits of said areas, being chosen according to the relationship: D1 - D2 < d, where D1 is the diameter of the central opening of the filter, D2 is the diameter of the working end of the rod, d is the diameter of the thread in the working condition. The device is preferably intended to be used for prophylaxis of thromboembolism of the pulmonary artery.

Подготовка устройства к работе осуществл етс  следующим образом.Preparation of the device for operation is carried out as follows.

Цилиндрический наконечник 6 утапливаетс  заподлицо во втулку 4 трубчатого поводка 5. Это выполн етс  с помощью перемещени  тросика 7 руко ткой 12, Предварительно в пазы 8 цилиндрического наконечника 6 уложены ветви петель 9 (фиг.The cylindrical tip 6 is flush flush into the sleeve 4 of the tubular leash 5. This is accomplished by moving the cable 7 with the handle 12, Previously, the branches of the loops 9 are laid in the grooves 8 of the cylindrical tip 6 (FIG.

4),four),

Через центральное отверстие во втулке 2 фильтра 1 пропускают обе петли 9 и, поддержива  их с некоторым нат гом, осаживают по ним фильтр 1 до соприкосновени  втулки 2 с втулкой 4 трубчатого поводка 5. Продолжа  сохран ть некоторое нат жение петель 9, с помощью руко тки 12 и тросика 7 вдвигают цилиндрический наконечник 6 в отверстие втулки 2 фильтра 1 так, чтобы цилиндрический наконечник 6 несколько выступал из отверсти  втулки 2 (фиг. 5). После этого развод т петли 9 на цилиндрические части наконечника 6 между пазами 8 и, нат гива  нить 3 с напр жением, прит гивают петли 9 к торцовой поверхности втулки 2 (фиг. 5).Both hinges 9 pass through the central opening in the bushing 2 of filter 1 and, supporting them with some tension, filter 1 against them until the bushing 2 comes in contact with the bushing 4 of the tubular leash 5. Continuing to maintain some tension of the hinges 9, with the handle 12 and the cable 7 push the cylindrical tip 6 into the opening of the sleeve 2 of the filter 1 so that the cylindrical tip 6 protrudes somewhat from the opening of the sleeve 2 (Fig. 5). Thereafter, loops 9 are placed on the cylindrical parts of the tip 6 between the slots 8 and, tensioning the thread 3 with tension, pull the loops 9 to the end surface of the sleeve 2 (Fig. 5).

Так как величина гарантированного радиального зазора б 0,5 dH, то петли 9 не могут пройти через зазор и прит гивают с напр жением втулку 2 фильтра 1 к торцовой поверхности втулки 4 трубчатого поводка 5. После этого нить 3, сохран   ее напр женность , закрепл ют окончательным узлом на трубчатом поводке 5, что обеспечивает сохранение жесткого и точного положени  фильтра 1 на трубчатом поводке 5 аппликатора .Since the magnitude of the guaranteed radial clearance is b 0.5 dH, loops 9 cannot pass through the gap and pull the bushing 2 of the filter 1 with tension to the end surface of the bushing 4 of the tubular leash 5. After that, the thread 3, keeping its intensity, fixed The final assembly on the tubular leash 5 ensures that the rigid and precise position of the filter 1 on the tubular leash 5 of the applicator is maintained.

Подготовленный таким образом фильтр 1 размещаетс  в капсуле 10 аппликатора, упаковываетс  и стерилизуетс  дл  последующего однократного применени .The filter 1 thus prepared is placed in the capsule 10 of the applicator, packaged and sterilized for subsequent single use.

Аппликатор с фильтром ввод т в нижнюю полую вену.The filter applicator is inserted into the inferior vena cava.

Дл  освобождени  фильтра от аппликатора перемещением трубчатого поводка 5 выталкивают фильтр 1 из капсулы 10, выполн ют манипул ции дл  его установки и фиксации в нижней полой вене, после чего отсоедин ют аппликатор от фильтра.To release the filter from the applicator by moving the tubular leash 5, push the filter 1 out of the capsule 10, perform manipulations to install it and fix it in the inferior vena cava, after which the applicator is disconnected from the filter.

Дл  отсоединени  аппликатора от фильтра цилиндрический, наконечник 6 с помощью руко тки 12 и тросика 7 полностьюTo disconnect the applicator from the filter, cylindrical, tip 6 with the handle 12 and cable 7 completely

После этого в центральном отверстии втулки 2 фильтра 1 остаютс  только две свободные петли 9, которые удал ютс  вместе с аппликатором без каких-либо усилий.is drawn into the sleeve 4 of the tubular driver 5. After that, in the central opening of the sleeve 2 of the filter 1, only two free loops 9 remain, which are removed together with the applicator without any efforts.

Замковое соединение в устройстве предложенной конструкции работоспособно и при наличии только одной петли, котора  располагаетс  и закрепл етс  также, как это показано на фиг, 5. В частности, это The locking connection in the device of the proposed construction is operational and with only one loop, which is located and secured also, as shown in FIG. 5. In particular, this

целесообразно, когда дл  петель используетс  не хирургическа  нить, а тонка  м гка  проволока.it is advisable that a thin soft wire, rather than a surgical thread, is used for the loops.
