- a known device for the implantation of an independent filter which has a central component, which is a second-party device, In the end, the external thread was made in the central part of the cylinder barrel of the filter with the internal thread (W, 15, 42, ⁇ 25, ⁇ , 25).
- a well-known filter is made in the form of an all-metal mixed casus, which consists of a single, fully-integrated, fully-equipped, fully-equipped, fully-equipped, fully-equipped complex.
- the tractor is located on the outside of the circuit.
- the transmitter prevents a rupture through the incision in the jugular vein to the implantation level in the inferior vena cava and prevents the burden of stress Then, turning the handles unscrews the end of the pipe from the central filter and removes the catheter and pipe from the body.
- an optional filter when using a known device, it is possible to install an optional filter with a device that is subject to a decrease in reliability.
- the filter in Vienna is allocated based on its installation and the direction of the device is set for - 2 - implantation.
- ⁇ ana ⁇ miches ⁇ i ⁇ ⁇ s ⁇ benn ⁇ s ⁇ ey the lower case, it is not ⁇ l ⁇ y vein is ⁇ lyuchen ⁇ ⁇ as ⁇ l ⁇ zhenie ⁇ si ⁇ a ⁇ d ugl ⁇ m ⁇ ven ⁇ zn ⁇ mu ⁇ uslu ⁇ vi, ch ⁇ ⁇ iv ⁇ di ⁇ ⁇ i im ⁇ - 5 lan ⁇ atsii ⁇ il ⁇ a ⁇ ⁇ l ⁇ neniyu ⁇ eg ⁇ ⁇ imaln ⁇ g ⁇ ⁇ - ⁇ e ⁇ echn ⁇ g ⁇ ⁇ as ⁇ l ⁇ zheniya.
- This device is equipped with a quick, easy-to-use quick-disconnect accessory, which is a 35-piece quick-connect.
- the filter is entered into the cassette of the catheter and the device is introduced to the implantation device at the expense of the non-removable device.
- the filter is equipped with a quick disconnect from the capsule and disconnects the device by pulling the handle inside. By doing this, the D-detailed part is freed and turned in by turns between the radial legs of the filter. Devices are taken from the organism.
- a significant disadvantage of the known device is a low degree of rigidity of the filter attaching to the filter. Non-critical gaps between a plastic filter plate and a part of a private device, between a failure in the filter center and a short circuit
- a well-known device is not universal in use, and, by name, it can not be used with filters of ancillary devices.
- the main task of the invention was to create a device for implantation of an alternative filter, with such
- This task is resolved in that a device for importing an integrated filter, which has a large share of the room, is connected to a roomy building.
- the appliance has two loops, each of which is located in one slot, and the other in the other.

- the device also contains a live device
- Trial 4 The castle is implemented in the form of a different one, in the described example, two, socket 8 (Fig. 1, 2, 3), is disconnected from the power supply
- the end of the training,, 8 are secured to the main section of the road 4, and the loops 8 have a longer length than the length of the parking area 4
- the terminal end has a capsule 12 for accommodating the filter I.
- page 7 5 The working end of page 7 5. is completed with a diagram and has at least two diametrically active partitions with a side cylinder.
- Fig. 4 shows one of the possible variants of the performance of the other end of the 7th part, where the latter has a cylindrical part and is equipped with an integral part for the outside Area of the cross section of each phase

- Section 3 of Section 2 is significantly smaller than the diameter of the ⁇ nit.
- the device is in accordance with the invention and is indicated in the case of filter I, which is packaged in the card 12 of the card.
- the devices for implanting an importable filter are used as follows.
- 35 Volume I introduces the optional catheter II into the inferior vena cava.
- the unit is moved to page 5 and the related channel 4 is turned off.
- - 10 - filter I from capsule 12 (this is shown in fig.), There are manipulations for its installation and fixation in the lower pollen vein, after the device is disconnected.
- central office 3 of filter I is a completely free and this is the same as connecting the filter I of 4 facilities for implantation without effort.
- step 5 For retraction of step 5, and separating the filter I ⁇ th step 4, the application of any kind is also not required.
- the device for implantation of an importable filter is intended for use with filters having 5 central forms of resistance, which are applicable for impairment.
Abstract
Un dispositif d'implantation d'un filtre intraveineux doté d'un orifice de passage comprend un câble creux (4), une tige flexible (5) située à l'intérieur du câble creux (4) ainsi qu'un moyen destiné à maintenir la position de la tige (5) par rapport au corps du câble creux (4). Un mécanisme de blocage se compose de deux boucles (8) d'un fil en matière élastique, les extrémités des boucles (8) étant fixées au corps du câble creux (4), la longueur des boucles (8) dépassant celle de la section du câble creux (4) entre le point de fixation et l'extrémité du câble creux (4), comprenant l'épaisseur du filtre (1). L'extrémité de travail (7) de la tige (5) est façonnée et présente deux zones diamétralement opposées ayant une surface latérale cylindrique, le diamètre de l'extrémité de travail (7) de la tige (5) compris dans les limites desdites zones, étant choisi selon la relation: D1 - D2 < d, dans laquelle D1 représente le diamètre de l'orifice central du filtre, D2 représente le diamètre de l'extrémité de travail de la tige, d représente le diamètre du fil à l'état de travail. Le dispositif est de préférence destiné à être utilisé dans la prophylaxie de la tromboembolie des artères pulmonaires.
