Embodiment Construction

[0158] Referring to the drawings, there is shown an occluding device 1 according to the present invention comprising a plurality of flexible bristles having an expanded configuration and a contracted configuration. The embolic device comprises a series of segments, wherein at least one segment 3 is directed distally and at least one segment 4 is directed proximally. In some cases, only the proximal section 4 and the distal section 3 are present.

[0159] The bristles of the proximal section 4 point proximally, while the bristles of the distal section 3 point distally.

[0160] A proximally directed segment is defined as a segment in which the bristles are directed proximally and the cone of the membrane (if present) is open at the proximal end. A distally directed segment is defined as a segment in which the bristles are directed distally and the cone of the membrane (if present) is open at the distal end.

[0161] At least one segment, in this case the proximal segment 3 , ...

Abstract

An embolisation device for promoting clot formation in a lumen comprises at least two segments (3,4), each segment (3,4) comprising a stem and a plurality of flexible bristles extending outwardly from the stem. The bristles have a contracted delivery configuration and a deployed configuration in which the bristles extend generally radially outwardly from the stem to anchor the device in a lumen. In the deployed configuration bristles of one segment (3) extend partially in a first longitudinal direction and the bristles of another segment (4) extend partially in a second longitudinal direction which is opposite to the first longitudinal direction. A flow restrictor (5) is located adjacent to a proximal end of the device and / or a flow restrictor (5') is located adjacent to the distal end of the device.

Description

technical field [0001] The present invention relates to an embolization device. Background technique [0002] Movement of conventional embolization coils occurs in 4-14% of transcatheter embolizations [1, 2]. The result of coil movement is an untargeted embolism, the effect of which depends on the final position of the coil. In the venous system, the consequences could be catastrophic, where it has been documented that the coil may migrate into the renal veins, the right atrium of the heart, the lungs (pulmonary artery). Retrieving coils percutaneously is very technically challenging and generally cannot be attempted because the coils are often trapped within organs and tissues. [0003] Coil movement can occur for various reasons as follows: [0004] Technical error: Coil or coil assembly released too far or too close to adjacent larger vessels or reticular tissue [3,4] [0005] • Areas of high blood flow may cause the coil to move. [0006] ·The coil does not match th...
