Abstract
Abstract An anchoring element including a replacement heart valve for the purposes of intraluminal anchoring of the heart valve element to mammalian hearts, the anchoring element having a small enough initial volume prior to its placement that it can be brought to its point of use using a catheter through a blood vessel and can be expanded there to its functionally correct dimensions. The anchoring element is shaped differently from a cylindrical shape such that it is connected to the aorta at the point of use at least in areas in a form-locked manner. This facilitates an especially good seating of the anchoring element containing the replacement heart valve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An anchoring element of a replacement heart valve for intraluminal anchoring of the replacement heart valve to mammalian hearts, the anchoring element comprises a low enough initial volume prior to its placement that it can be placed through a blood vessel to its point of use using a catheter and expanded there to its functionally correct dimensions, wherein the anchoring element is shaped in a deviation from a cylindrical form, such that it is configured to be connected in a form-locked manner to the aorta at a point of use; comprises a widening section configured to extend in a radial direction at the point of use at a heart outlet; and is tailored to an interior shape of the bulbi and has a curved contour to fit an interior shape of the aorta and its curved contour.
Claim 2
Dependent Claim
137 words
An anchoring element of a replacement heart valve for intraluminal anchoring of the replacement heart valve to mammalian hearts, the anchoring element comprises a low enough initial volume prior to its placement that it can be placed through a blood vessel to its point of use using a catheter and expanded there to its functionally correct dimensions, wherein the anchoring element is shaped in a deviation from a cylindrical form, such that it is configured to be connected in a form-locked manner to the aorta at a point of use; comprises a widening section configured to extend in a radial direction at the point of use at a heart outlet; and is tailored to an interior shape of the bulbi and has a curved contour to fit an interior shape of the aorta and its curved contour.
Claim 3
Dependent Claim
19 words
An anchoring element according to claim 1 , further comprising cutouts for arterial outlets located near the anchoring element.
Claim 4
Dependent Claim
23 words
An anchoring element according to claim 1 , further comprising a profiled exterior having at least one of small teeth, spines or peaks.
Claim 5
Dependent Claim
36 words
An anchoring element according to claim 1 , wherein the anchoring element has dimensions and length corresponding to the aorta from an area of the bulbi up to at least an outlet for the truncus brachiocephalicus.
Claim 6
Dependent Claim
29 words
An anchoring element according to claim 1 , including a number of meandering thread-like structures forming a ring, said thread-like structures being connected among themselves through other thread-like structures.
Claim 7
Dependent Claim
47 words
An anchoring element according to claim 1 , wherein the anchoring element has a protrusion permeable to blood near at least one arterial outlet, the protrusion is adapted to sit against a beginning section of a wall of a respective discharging artery at the point of use.
Claim 8
Dependent Claim
24 words
An anchoring element according to claim 1 , comprising a shape-memory material, including at least one of a shape-memory polymer or a memory metal.
Claim 9
Dependent Claim
24 words
An anchoring element according to claim 7 , wherein the anchoring element is made of a memory metal that is a nickel/titanium shape-memory alloy.
Claim 10
Dependent Claim
29 words
An anchoring element according to claim 1 , wherein the anchoring element has individual spatial coordinates essentially the same as that of an aortic lumen of the respective patient.
