Implantable device

Abstract

Disclosed is an implantable device () to be used in a human and/or animal body for occluding or partially occluding defective openings, hollow spaces, organ tracts, etc. or creating a defined connecting opening between walls, organs, hollow spaces, etc. Said implantable device () comprises a support structure which has a great length-to-width ratio along an axis () in a first operating state (primary shape) while having a smaller length-to-width ratio along said axis () in a second operating state (secondary shape). The support structure is provided with a proximal () and a distal section () and is formed from a single wire-type element () by intercoiling and/or intertwining and/or interweaving like a tissue and/or a cluster and/or a net. Also disclosed is a placing system especially for such an implantable device, comprising an advancing element (), a directing wire () and/or an inner mandrin, and at least one holding wire (). The directing wire () and the at least one holding wire () are used for cooperating with a proximal end of the implantable device (), the implantable device () being transformable from a primary shape into a secondary shape and vice versa by moving the holding wire () and the directing wire () relative to the advancing element ().
