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.

Area of technology

The invention is subject to medical equipment and more accurately the equipment for implantation of an intravenous filter is more accurately affected.

Preceding level of technology

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, Α25, Α, 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. However, 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.

With the help of deductions, the deduction of the inventory from the area of Economics and the sale of it through the use of the relevant connection of the filter and the answer

The castle of the United Kingdom. After this location, the location is fixed.

Further, 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. Behind-

15 In this case, 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.

20 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

25 filter locations are relatively unhappy due to the possibility of free space Other convenient accommodations at the time of filter release are impairing the precise) implantation in the lower

30 vein.

In addition, a well-known device is not universal in use, and, by name, it can not be used with filters of ancillary devices.
