Abstract
Embolic protection device for insertion into an aortic arch, with a filter unit, a frame and a feed unit, wherein the filter unit is arranged at the frame and the frame provides a proximal area having a proximal shape, which is arranged in an inner area of the frame and is connected to the feed unit, wherein the proximal shape has a first part and a second part, wherein the second part is formed at one end of the first part.
Claims15
Embolic protection device (1) for insertion into an aortic arch, comprising
- a filter unit (3),
- a frame (5) with a proximal end and a distal end and
- a feed unit (7) located at the proximal end of the frame,
- wherein the filter unit (3) is arranged within the frame (5) and the frame (5) is comprised of a wire and provides a proximal area (9), comprising a proximal shape (11) and provides a distal area (2) comprising a distal shape (4),
- wherein the frame (5) defines a generally oval two-dimensional area,
- where the proximal shape (11) is arranged at the proximal end of the frame (5) and is connected to the feed unit (7),
- wherein the proximal shape (11) comprises a first part (13) and a second part (15),
- wherein the second part (15) is formed at one end of the first part (13) and the second part is connected to the feed unit,
- wherein the first and second parts (13, 15) form the proximal shape (11), wherein the proximal shape (11) extends over and under the generally oval two-dimensional area of the frame (5), and
- wherein the distal shape (4) has a constriction (12) of the wire of the frame (5) into an interior of the generally oval two-dimensional area of the frame (5).
