Abstract:
A device for ablation of an aortic valve of a human heart by a minimally invasive surgical operation, comprising:a body having distal and proximal ends which is for introduction inside the aorta, the body being for fixing relative to the aorta by at least one holding device which is attached to the body and which is for engaging the aorta; a drive shaft, projecting centrally at least in part through the body and outside of the distal end; a cutting device fixedly mounted for rotation on the drive shaft in a region outside of the distal end for abating the aortic valve; and an aspiration device for aspirating debris from cutting of the aortic valve through at least one passage in the body facing the aorta, and disposed radially outward from the drive shaft, extending through the body and a catheter for fluid communication with the proximal end and the aspiration device for aspirating debris in aortic blood of a patient resultant from ablation of the aortic valve, and wherein the body is a hollow cylinder for attachment to a distal end of the catheter while inside the patient and comprises an electric motor from which projects the drive shaft that extends through the hollow cylinder and through a cover plate at the distal end connected to the hollow cylinder.
