Problems solved by technology

[0008] Accordingly, it is problematic in such devices to introduce a fixation element with such a large cross-section into the heart, which is currently performed essentially surgically by opening the heart, using correspondingly expensive and dangerous surgery

Embodiment Construction

[0053] figure 1 The device according to the invention is shown in side view with a closure body 1 , here a fillable closure body of the type described above, which has a cavity 4 which is arranged around a base body 1 a. The cavity 4 is bounded outwards by a wall 4a. The closing body 1 is shown here on the left.

[0054] The support strip 2 extending away from the closure body 1 on the right forms an approximately basket or cage-shaped structure as a whole and forms the fixation element according to the invention with said structure, which is here expanded after implantation. middle.

[0055] The supporting strip 2 is divided into a closing body-side supporting strip section 2a, which starts from the closing body 1 or the base body 1a and branches into two supporting strip branches 2b1 (to the right) and 2b2 (to the right). Left). The two support strip branches 2b1 , 2b2 of the different support strip sections 2a merge again to form a connecting body-side support strip sec...

Abstract

The invention relates to an implantable device for improving or treating a heart valve insufficiency, comprising a closure body (1) and at least one anchoring element fastened thereto, by way of whichthe closure body (1) can be fastened in the heart, preferably in the atrium of the heart. The anchoring element comprises a plurality of contact strips (2) extending between the closure body (1) anda shared connecting element (3) that is spaced from the closure body (1). The connecting element (3) can be brought into a first and a second position each spaced from the closure body, whereby the contact strips (2) undergo a change in shape, wherein in the first position, the connecting element (3) is spaced further apart from the closure body (1) than in the second position, and in the second position, the connecting element (3) is arranged between the contact strips (2).

Description

technical field [0001] The invention relates to an implantable device for improving or eliminating heart valve insufficiency, comprising a closure body and at least one fixation element fastened thereon, with which the closure body can be fixed in the heart , preferably fixed in the atrium of the heart. Background technique [0002] In the prior art, implantable devices of this type are known, for example, from the patent application DE 10 2012 010 798 A1 of the same inventor and in the patient during normal heart activity the heart valves do not close sufficiently and thus in the heart Used when misflow occurs between the ventricle and atrium. [0003] An implantable device of the type mentioned at the outset is then implanted in the patient's heart such that the closure body is arranged in the channel region of the heart valve and thus the sail of the heart valve rests outside the closure body when closing, whereby , the embedded closing body closes the otherwise remaini...
