Abstract:
1. A vascular medical device for use in a blood vessel of a patient comprising: an expandable stent which takes the form of a small diameter skeletal tubular member having a thin wall, said wall of said skeletal tubular member including a plurality of cells which are formed by a plurality of interconnected strut members; a plurality of elongated removable slat members interwoven between at least two of said plurality of strut members to temporarily attach said plurality of said removable slat members to said skeletal tubular member to thereby provide a substantially continuous cover for the peripheral surface of said skeletal tubular member such that said substantially continuous cover impedes the flow of blood through the peripheral surface of said medical device when deployed within the blood vessel, wherein each slat member has a circumferential width greater than its wall thickness; and a plurality of tethers each attached to one of said plurality of removable slat members in order to selectively remove any one of said removable slat members to thereby provide a selective passage for blood flow through a portion of the wall of said skeletal tubular member to re-establish patency in a branching vessel while impeding blood flow through other portions of said medical device.
