Abstract

An expandable stent to enhance the supply of blood to downstream tissue which is being supplied with blood through a diseased intracranial artery with a stenosis formed therein by plaque with a bore therethrough. The expandable stent includes first and second end portions joined by a central portion. The central portion is configured in the expanded state of the stent to be located in the bore of the stenosis with the first and second end portions abutting non-diseased parts of the artery adjacent the proximal and distal ends of the stenosis for anchoring the stent in the artery. The central portion with the stent in the expanded state is configured to apply a radial outward pressure to the stenosis such that the diameter of the bore of the stenosis is maintained at its current diameter or increased to approximately 50% of the non-diseased parts of the artery.

Abstract

An expandable stent (1) to enhance the supply of blood to downstream tissue which is being supplied with blood through a diseased intracranial artery (100) with a stenosis (102) formed therein by plaque with a bore (103) therethrough. The expandable stent (1) comprises first and second end portions (3,4) joined by a central portion (5). The central portion (5) is configured in the expanded state of the stent (1) to be located in the bore (103) of the stenosis (102) with the first and second end portions (3,4) abutting non-diseased parts (104,106) of the artery (100) adjacent the proximal and distal ends (105,107) of the stenosis (102) for anchoring the stent (1) in the artery (100). The central portion (5) with the stent (1) in the expanded state is configured to apply a radial outward pressure to the stenosis (102) such that the diameter of the bore (103) of the stenosis (102) is maintained at its current diameter or increased to approximately 50% of the non-diseased parts (104,106) of the artery (100).

Abstract

A stent for use in a method for the treatment of an aneurysm (3) in an intracranial vessel (5) comprises an expandable framework (7) and a film (22) formed thereon by spraying, sputtering, dipping or the like of a polymer material. The stent comprises a central bridging portion (25) for bridging and closing the aneurysm (3) and first and second non-bridging portions (26) and (27). First communicating openings (29a) extend through the film (22) in the central bridging portion (25) and communicate with a central diverting bore (17) extending longitudinally through the framework (7) for accommodating blood flow therethrough to the aneurysm (3). Second communicating openings (29b) extending through the first and second non-bridging portions (26) and (27) accommodate blood flow from the diverting bore (17) to side vessels (30) and perforators (31 ) extending from the vessel (5) at respective opposite ends of the aneurysm (3). The area of the first communicating openings (29a) is less than the area of the second communicating openings (29b). The spacing between the first communicating openings (29a) is greater than the spacing between the second communicating openings (29b) so that blood flow is considerably restricted to the aneurysm (3), while normal blood flow is maintained to the side branches (30) and perforators (31).
