Problems solved by technology

However, a drawback associated with this device is that in order to cool the capture arms before they are released into the bloodstream and thus keep them below the transition temperature, it must be moved past the thrombus in a secondary conduit producing a cooling effect, or the heating system must b

Embodiment Construction

[0080] Figure 1 is a diagram of a first embodiment of the invention shown as a side view. The device has in particular a cage-like structure 1 and a distal element 2 as main components. Fibers 3 protrude radially outwards from the distal element 2 . The cage structure 1 consists of struts 4, the main part of which extends in the longitudinal direction. The device is used to capture a thrombus 5, initially, with the help of the distal element 2 and the fibers 3 protruding therefrom, by moving the distal element 2 backwards in the proximal direction and finally maneuvering said thrombus into the cage In structure 1,. In the side views shown here, proximal always means to the left and far to the right. The distal element 2 and the cage structure 1 are movable by independent guide wires 6 and 7 . The cage-like structure 1 converges at its proximal end centrally in a sleeve 8 to which a guide wire 7 for the cage-like structure 1 is secured, while a guide wire 6 for the distal e...

Abstract

The invention relates to an assembly comprising a support (1, 3, 4) for intervertebral prostheses and intervertebral prostheses (2) that are provided with different widths and are composed of two final plates (21, 22) with a ventral flange (23, 24) and an intermediate joint core (20). The support (1, 3, 4) is equipped with a base plate (10, 30, 40) which encompasses holes (12, 32, 42) for accommodating one of the intervertebral prostheses (2) and is larger than the maximum width of the intervertebral prostheses (2). A couple of steps (17) are embodied on at least one longitudinal edge (13) of the hole (12, 32, 42).; The facing sides (18) of said couple of steps (17) are disposed at a specific distance from each other so as to center the flange (24) of an intervertebral prosthesis (2) that is inserted into the hole (12, 32, 42), thus making it possible to insert intervertebral prostheses (2) having different widths into the holes (12, 32, 42) and retain the same in a centered position in the holes (12, 32, 42) regardless of the actual width thereof.

Description

technical field [0001] The present invention relates to a device for removing foreign bodies and thrombi from body cavities and blood vessels using at least one guide wire with a distal element. Background technique [0002] Thromboembolic diseases such as cardiac infarction, pulmonary embolism, peripheral thrombosis, organ embolism, etc., are typically caused by thromboembolism (hereinafter simply referred to as thrombus or thrombus), that is, the formation of a viscoelastic blood clot in a blood vessel that it completely or partially occludes , which includes platelets, fibrin, coagulation factors, etc. Blockage of an organ's arteries also disrupts the supply of oxygen and nutrients to the involved tissues. Disturbances of functional metabolism associated with loss of function are followed by disturbances of structural metabolism, leading to destruction of the relevant tissue (infarction). The organs most often affected in this way are the heart and brain. However, the ...
