Abstract

The support ring proposed consists of two rings (10, 12) held a constant distance apart by three connecting struts (14) and is characterized by the fact that the upper ring has a slightly smaller diameter than the lower ring and, represented as rolled out, the rings form three waves, the connecting struts being located near the crests of the waves.

Description

Support ring for supporting a biological aortic valve prosthesis

The invention relates to a support ring for supporting ei¬ ner aortic valve prosthesis, consisting of two gene at a constant distance from each other and extending Rin¬ ben three rings interconnecting Stre¬.

In DE 36 08 435 C2, such a support ring is shown in which the two rings have an equal diameter and extend Durch¬ the two rings in each case to one Ebe¬ ne.

The known support ring does not consider the anatomi¬ rule conditions sufficient.

The object of the invention is based is to develop the vorbe¬ knew supporting ring such that the anato¬ mix ratios are better taken into account.

According to the invention this object is achieved in that the upper ring has a slightly smaller diameter than the lower ring and the rings forming three shafts in a abge¬ wound representation, wherein the struts miteinan¬ the rings in the region of the wave crests of the combine.

The diameter of the upper ring is in this case preferred wise 1.5 to 2.5 mm less than that of the lower ring, the height of the wave peaks and the depth of the wave troughs is preferably between 2 and 6 mm.

The braces should be wider than the rings.

As a material particular titanium comes into consideration. To avoid weld joints or the like. The support ring should be made of one piece.

The invention is explained below with reference to a drawing. The single figure shows the support ring in perspective.

The support ring consists of two rings 10, 12, each wavy verlau¬ while maintaining their parallelism fen. The height of the wave peaks and the depth of Wellen¬ valleys is in each case 2 to 6 mm, so that the Ebe¬ ne of the vertices of the lower ring 12 and the Ebe¬ of the vertices of the top ring 10 ne a distance of 2 to 12 mm from each other, to have.

The diameter of the upper ring 10 is 1.5 to 2.5 mm less than that of the lower ring.

In the - preferred - regular arrangement of the struts that have an angular distance of 120 ° of one another,.

For implanting a biological Herzklappenprä¬ is ready in the supporting ring as described in DE 39 10 971 Cl be¬ written sewn and then introduced with the support ring in the patient's aorta.

Claims
