Abstract
An aortic protection device including a mesh lumen shaped and sized to extend along the aorta, from a heart-side of a brachiocephalic artery exit from the aorta to distal of a left subclavian artery exit from the aorta, wherein the mesh lumen is arranged to change a porosity of mesh pores in response to external control. Related apparatus and methods are also described.
Claims25
An aortic protection device comprising:
- a heart-proximal ring;
- and
- a mesh lumen portion connected to the heart proximal ring, shaped and sized to extend along the aorta, from a heart-side of a brachiocephalic artery exit from the aorta to distal of a left subclavian artery exit from the aorta, and
- a mechanism for changing a porosity of mesh pores in response to external control of a control wire attached to a heart-proximal end of the mesh lumen portion and a control wire attached to a more heart-distal part of the mesh lumen portion, while said mesh lumen remains anchored to the aorta in a manner which allows filtering of blood- borne debris from passing through said arteries;
- wherein the mesh lumen portion is arranged to change a porosity of the mesh pores to completely block blood from entering side arteries.
2 more elements
A method of protecting a patient from blood-borne debris, comprising:
- anchoring an aortic protection device comprising anchoring a heart-proximal ring connected to a mesh lumen portion at a heart-side of a brachiocephalic artery exit from an aorta;
- deploying the mesh lumen to extend to distal of a left subclavian artery exit from the aorta, and
- controlling the mesh lumen to decrease porosity of the mesh pores during a heart operation, while the aortic protection device remains anchored and deployed such that the mesh lumen filters blood flow to arteries branching off the aorta and blocks at least some blood-borne debris from entering thereto, thereby protecting the patient from blood-borne debris;
- wherein the controlling comprises completely blocking blood from entering side arteries.
