An occluder for occluding a passage in a body, especially in a left atrial appendage (LAA), comprises elongate members having a first end and a second end, the ends being held in or attached to holders, wherein the elongate members extend independently from each other between the holders and wherein the elongate members are collectively enveloped by at least one jacket. The jacket restricts a bending motion of the elongate members when their first ends are approximated to their second ends by moving the two holders relatively to each other. The occluder uses an expanding structure which can be easily handled whereby the movement of the elongate members is restricted by at the jackets which envelop the elongate members. At least the elongate members can be made of bioresorbable material.

Occluder

An occluder including at least one occluding body, a multiple of elongate members forming an expanding unit capable of expanding into at least one fixation structure for fixing the occluding body within the passage thereby expanding the occluding body), the elongate members penetrating the occluding body, a locking unit for locking the expanding unit in its expanded state, fixation bushes for restricting relative movement between the elongate members and the occluding body, each fixation bush surrounding one single elongate member and abutting the occluding body, at least one thread and wherein at least one of these fixation bushes is fastened to the at least one occluding body with this at least one thread, the thread penetrating the at least one bush and the occluding body.
