Implantable braided stroke preventing device and method of manufacturing
First Claim
1. An implantable deflecting device for positioning in the vicinity of an arterial bifurcation for causing embolic material flowing toward a first branch of the bifurcation to be deflected into the second branch of the same bifurcation, comprising a deflecting filtering element suitable to deflect the flow of embolic material flowing toward said second branch, while filtering the blood flowing toward said first branch, said device comprising a braided tubular body having a contracted state with a first diameter, and an expanded state having a second diameter greater than said first diameter.

16. A method for preventing the flow of embolic material flowing toward a first branch of an arterial bifurcation from entering into it, comprising implanting upstream to said bifurcation a deflecting filtering element suitable to deflect the flow of said embolic material into a second branch, said device comprising a braided tubular body having a contracted state with a first diameter, and an expanded state having a second diameter greater than said first diameter.
- 17. A method for preventing the flow of embolic material flowing in the CCA from accessing the ICA, comprising implanting in the vicinity of a bifurcation of an artery leading to, or located in, the common carotid artery (CCA) on the one hand, and leading to a non-vital artery on the other hand, a deflecting filtering element suitable to deflect the flow of embolic material flowing toward the CCA, into said non-vital artery, while filtering the blood flowing toward the CCA, said device comprising a braided tubular body having a contracted state with a first diameter, and an expanded state having a second diameter greater than said first diameter.
- 19. A method for preventing cerebralvascular diseases or their recurrence, comprising implanting in the vicinity of a bifurcation of an artery leading to, or located in, the common carotid artery (CCA) on the one hand, and leading to a non-vital artery on the other hand, a deflecting filtering element suitable to deflect the flow of embolic material flowing toward the CCA, into said non-vital artery, while filtering the blood flowing toward the CCA, said device comprising a braided tubular body having a contracted state with a first diameter, and an expanded state having a second diameter greater than said first diameter.
