Abstract
Abstract A valve prosthesis ( 9 ) for implantation in the body by use of catheter ( 11 ) comprises a stent made from an expandable cylinder-shaped thread structure ( 2,3 ) comprising several spaced apices ( 4 ). The elastically collapsible valve ( 6 ) is mounted on the stent as the commissural points ( 5 ) of the valve ( 6 ) is secured to the projecting apices ( 4 ). The valve prosthesis ( 9 ) can be compressed around the balloon means ( 13 ) of the balloon catheter ( 11 ) and be inserted in a channel, for instance in the aorta ( 10 ). When the valve prosthesis is placed correctly the balloon means ( 13 ) is inflated thereby expanding the stent and wedging it against the wall of the aorta. The balloon means is provided with beads ( 14 ) to ensure a steady fastening of the valve prosthesis on the balloon means during insertion and expansion. The valve prosthesis ( 9 ) and the balloon catheter ( 11 ) make it possible to insert a cardiac valve prosthesis without a surgical operation comprising opening the thoracic cavity.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
102 words
A method of endovascularly delivering a valve through a blood vessel, comprising the step of: providing a tissue valve and a support structure, the support structure being movable from a collapsed shape to an expanded shape, the tissue valve being configured to permit blood flow in a direction and prevent blood flow in an opposite direction; connecting the tissue valve to the support structure; passing the support structure through a blood vessel with the support structure in the collapsed position; and securing the tissue valve and the support structure to a desired valve location with the support structure in the expanded shape.
Claim 2
Independent Claim
102 words
A method of endovascularly delivering a valve through a blood vessel, comprising the step of: providing a tissue valve and a support structure, the support structure being movable from a collapsed shape to an expanded shape, the tissue valve being configured to permit blood flow in a direction and prevent blood flow in an opposite direction; connecting the tissue valve to the support structure; passing the support structure through a blood vessel with the support structure in the collapsed position; and securing the tissue valve and the support structure to a desired valve location with the support structure in the expanded shape.
Claim 3
Dependent Claim
20 words
The method of claim 1 , wherein: the providing step is carried out with the support structure comprising a ring.
Claim 4
Dependent Claim
19 words
The method of claim 2 , wherein: the providing step is carried out with the ring being a cylinder.
Claim 5
Dependent Claim
28 words
The method of claim 2 , wherein: the providing step is carried out with the support structure having at least one commissure support extending outwardly from the ring.
Claim 6
Dependent Claim
20 words
The method of claim 4 , wherein: the providing step is carried out with the support structure comprising a wire.
Claim 7
Dependent Claim
20 words
The method of claim 5 , wherein: the providing step is carried out with the wire forming a closed loop.
Claim 8
Dependent Claim
27 words
The method of claim 5 , wherein: the providing step is carried out with the wire forming at least one commissure support extending outwardly from the ring.
Claim 9
Dependent Claim
17 words
The method of claim 1 , wherein: the connecting step is carried out before the passing step.
Claim 10
Dependent Claim
27 words
The method of claim 1 , further comprising the step of: expanding the support structure from the collapsed shape to the expanded shape before the securing step.
Claim 11
Dependent Claim
33 words
The method of claim 9 , wherein: the expanding step is carried out by inflating a balloon so that the balloon moves the support structure from the collapsed shape to the expanded shape.
Claim 12
Dependent Claim
21 words
The method of claim 1 , wherein: the passing step is carried out by coupling the support structure to a catheter.
Claim 13
Dependent Claim
21 words
The method of claim 1 , wherein: the providing step is carried out with the tissue valve having three valve leaflets.
Claim 14
Dependent Claim
21 words
The method of claim 1 , wherein: the passing step is carried out with the desired valve location being an artery.
Claim 15
Dependent Claim

Claim 17
Independent Claim
133 words
A method of endovascularly delivering a valve through a blood vessel, comprising the step of: providing a valve having a support structure movable from a collapsed shape to an expanded shape, the valve being configured to permit blood flow in a direction and prevent blood flow in an opposite direction, the support structure having a ring with at least one commissure support extending from the ring, the commissure support supporting the valve; passing the support structure through a vessel to a desired valve location with the support structure in the collapsed position; expanding the support structure to the expanded shape with an expandable device thereby securing the valve to the desired valve location; and removing the expandable device after the expanding step is completed thereby leaving the valve in the desired valve location.
