Embodiment Construction

[0056] The occluder according to a preferred embodiment is based on the implant disclosed in document WO 2012 / 156415. However, the occluder may also be based on an occluder as described in document WO 2005 / 074813; ie an occluder without a surrounding shield. The occluder may also be based on an occluder as described in documents US 6 488 706 and in document US 2003 / 0149463, ie an occluder with a single occluding body. The occluder according to the invention may also have another shape and function in another way as described below.

[0057] The occluder is preferably used as an implant for closing an internal channel, eg a hole in the atrial or ventricular septum, the left atrial appendage or another channel in the human or animal body which it is desired to close. Implants are compressible for insertion into the body. For this insertion, a delivery mechanism is used. For example, the delivery mechanism includes an introduction sheath, two delivery catheters, and a guide wi...

Abstract

An occluder for blocking channels in a circulatory system, the occluder comprising: at least one blocking body (4, 5) for blocking channels; a plurality of elongate members (1), the A plurality of elongated members (1) form an expansion unit capable of being expanded into at least one fixation structure for securing the occlusion body (4, 5) within the channel, thereby expanding the occlusion body (4, 5) , the elongated member (1) passes through at least one occluding body (4, 5); the locking unit (2, 3), the locking unit (2, 3) is used to lock the expansion unit in its expanded state; and the fixing liner Sleeves (10), fixed bushes (10) are used to limit the relative movement between the elongated member (1) and at least one occluding body (4, 5), each fixed bushing (10) surrounds a single long shaped member (1) and is adjacent to one of the at least one occluder bodies (4, 5); wherein the occluder also includes at least one wire (11, 12), and wherein these fixed bushings ( 10) at least one fixed bushing is fastened to at least one occluding body (4, 5) by means of the at least one thread (11, 12) which passes through the at least one bushing (10) and the occluding body ( 4, 5). This occluding body ensures that the tiny bushes cannot wander in the human or animal body and improves even occluders that already have a protective shield.

Description

technical field [0001] The present invention relates to an occluder for occluding a passageway in a circulatory system, and more particularly, to a body passageway for occluding a body passageway in the human body—such as an orifice through the atrial septum or ventricular septum or in a body passageway The orifice in - the occluder. Background technique [0002] Document US 6 488 706 discloses an implant that works well for blocking channels in the circulatory system. Such implants have particular application as cardiology implants, by means of which, for example, openings through the atrial or ventricular septum can be closed. The implant is configured to be deployed or established at a desired location in the body. The occluder includes a plurality of thin linear elongate members forming a fixed structure and a single occluder body, i.e. a disc-shaped flexible membrane - is inflated in the body passage by the fixation structure. The fixed structure is locked in the ex...
