Patent ID: 7338467

Claim:
A device for minimally invasive, intravascular aortic valve extraction inside the aorta comprising: a perfusion catheter having at least one perfusion channel designed as a hollow channel; and at least two dilation units disposed at a distance from each other at the distal catheter region in the longitudinal extension of said catheter, both said dilation units being projected through by said perfusion catheter and forming, in an inflated state, an at least practically fluid-tight occlusion with the aortic wall, wherein at least a dilation unit disposed on the proximal side comprises an elastic, inflatable material and is provided with at least one passage outside of said perfusion catheter, wherein said at least one passage projects through said dilation unit disposed on the proximal side and is completely surrounded by said dilation unit disposed on the proximal side and through which at least one auxiliary catheter can be introduced for aortic valve ablation in a fluid-tight manner, and wherein the elastic, inflatable material of the dilation unit disposed on the proximal side seals said at least one passage fluid-tight without the provision of an auxiliary catheter when the dilation unit disposed on the proximal side is in an inflated state.
