Abstract

A device for medical, use and particularly a filter intended to be placed in a vessel, provided with flat branches, called fixing branches, which cut off the blood flow when the device is placed in the vessel. The extremities of the fixing branches are locked inside of at least one ogival head by means of a locking art and the shape of said extremities is adapted to the internal and external peripheries, respectively of the ogival head and of the locking part. According to a first embodiment, the locking part and the ogival head being cylindrical parts, each fixing branch has a slightly curved extremity so as to adapt itself to the internal periphery of the ogival head and to the external periphery of the locking part. According to a second embodiment, the internal and external peripheries, respectively of the ogival head and of the locking part form regular polygons of which the number of sides is equal to the number of fixing branches of the filter, and of which the sides are parallel by pairs.
