Abstract
Abstract An aortic valve supporting device having an annular portion located around a central axis with stenting arms extending axially from the annular portion. A hiatus is formed in the annular portion to permit the annular portion and the stenting arms to be positioned around the aorta with the stenting arms in position to apply a supporting force to the aortic valve.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
83 words
An aortic valve supporting device comprising: an annular portion located around a central axis, a plurality of stenting arms extending axially from the annular portion, a hiatus formed in the annular portion to permit the annular portion and the stenting arms to be positioned around an aorta with the stenting arms located to apply a supporting force to the aortic valve, and a rotatable member on the annular portion for closing the hiatus after the supporting device has been positioned around the aorta.
Claim 2
Dependent Claim
83 words
An aortic valve supporting device comprising: an annular portion located around a central axis, a plurality of stenting arms extending axially from the annular portion, a hiatus formed in the annular portion to permit the annular portion and the stenting arms to be positioned around an aorta with the stenting arms located to apply a supporting force to the aortic valve, and a rotatable member on the annular portion for closing the hiatus after the supporting device has been positioned around the aorta.
Claim 3
Dependent Claim
15 words
A device according to claim 1 wherein the device is made of a biocompatible plastic.
Claim 4
Dependent Claim
15 words
A device according to claim 1 wherein the annular portion includes fabric to facilitate suturing.
Claim 5
Dependent Claim
52 words
A device according to claim 1 wherein the member for closing the hiatus comprises a flange on the annular portion extending away from the axis and which flange is surrounded by a rotatable cap having a mating hiatus such that rotation of the cap will close the hiatus in the aortic valve.
