Intra-aortic device
An intra-aortic device comprising a filter and a frame defining the shape of the filter, wherein the frame is intrinsically curved in a superior direction by a proximal superior bend and/or a distal superior bend, whereupon installation in an aorta, the M frame flattens.
1. An intra-aortic device comprising a filter member and a frame made from at least one wire and defining the shape of the filter member;
a first crimping member arranged at a distal region of the frame and the first crimping member is formed to protrude inwards;
a catheter attachment having an elongated shape arranged at a proximal region of the frame wherein the catheter attachment is arranged to move freely in 360 degrees.
2. The intra-aortic device of claim 1 , wherein a second crimping member is arranged at the proximal region.
3. The intra-aortic device of claim 2 , wherein the catheter attachment is attached to the frame via the second crimping member.
4. The intra-aortic device of claim 2 , wherein the second crimping member is a loop formed of the frame.
5. The intra-aortic device of claim 2 , wherein the second crimping member is formed to protrude inwards.
6. The intra-aortic device of claim 2 , wherein the second crimping member facilitate collapsing the frame along a longitudinal axis of frame.
7. The intra-aortic device of claim 1 , wherein the first crimping member is a loop formed of the frame.
8. The intra-aortic device of claim 1 , wherein the first crimping member facilitate collapsing the frame along a longitudinal axis of frame.
9. The intra-aortic device of claim 1 , wherein the filter member is configured to span more than one artery branching from the aorta.
10. The device of claim 1 , wherein the frame is configured to be held in contact with both an ascending aorta and a descending aorta, simultaneously.
11. The intra-aortic device of claim 1 , wherein the filter member comprises a plurality of woven fibres forming a mesh.
12. The intra-aortic device of claim 1 , wherein the filter member comprises pores having a median pore size of less than 1 mm.
13. The intra-aortic device of claim 1 , wherein the frame is made from nitinol.
14. The intra-aortic device of claim 1 , wherein the frame and filter member have a circular, elliptical or elongated shape.
15. The intra-aortic device of claim 1 , wherein the frame is a spring ring wire.
16. The intra-aortic device of claim 1 , wherein there is nothing extending further than the frame.
17. The intra-aortic device of claim 1 , wherein the catheter attachment is a stem.
18. The intra-aortic device of claim 1 , wherein a plane of the frame is substantially transverse going from an ascending aorta to a descending aorta.
19. The intra-aortic device of claim 1 , wherein the filter member is made from a polymer.
20. The intra-aortic device of claim 1 , wherein at least one radiopaque element is affixed to or incorporated into portions of the frame.
21. The intra-aortic device of claim 1 , wherein the frame is encircling the filter.
