Abstract

An implantable device for positioning in the vicinity of the bifurcation of the common carotid artery (CCA) into the internal carotid artery (ICA) and the external carotid artery (ECA) comprises a deflecting element suitable to deflect the flow of embolic material flowing in the CCA toward the ICA, into the ECA.

Claims

1. A method for preventing the flow of embolic material flowing in the CCA from accessing the ICA, comprising deflecting the flow of said embolic material into the ECA without blocking the ICA.

2. A method according to claim 1, comprising implanting in the vicinity of the bifurcation of the common carotid artery (CCA) into the internal carotid artery (ICA) and the external carotid artery (ECA), a deflecting device comprising a deflecting element suitable to deflect the flow of embolic material flowing in the CCA toward the ICA, into the ECA.

3. A method for treating a patient suffering from, or suspected of suffering from, the generation of embolic material, comprising preventing the flow of embolic material flowing in the CCA from accessing the ICA by deflecting the flow of said embolic material into the ECA without blocking the ICA.

4. A method for preventing cerebralvascular diseases or their recurrence, comprising implanting in the vicinity of the bifurcation of the common carotid artery (CCA) into the internal carotid artery (ICA) and the external carotid artery (ECA), a deflecting device comprising a deflecting element suitable to deflect the flow of embolic material flowing in the CCA toward the ICA, into the ECA.

5. A method according to claim 4, wherein the cerebrovascular disease is a stroke.

6. A method according to claim 4, wherein the deflecting device is provided in, or coupled to, a stent.

7. A method for preventing the flow of embolic material flowing in the CCA from accessing the ICA, comprising deflecting the flow of said embolic material into the ECA and implanting in the vicinity of the bifurcation of the common carotid artery (CCA) into the internal carotid artery (ICA) and the external carotid artery (ECA), a deflecting device comprising a deflecting element suitable to deflect the flow of embolic material flowing in the CCA toward the ICA, into the ECA.
