A medical device for creating an anastomosis between a first body conduit and a second body conduit, the device comprising: a frame being formed by an elongate member, the elongate member defining: a first apposition portion including at least one wire loop configured to conform to a geometry of a first tissue surface of the first body conduit and to provide an apposition force against the first tissue surface; a second apposition portion including at least one wire loop configured to conform to a geometry of a second tissue surface of the second body conduit and to provide an apposition force against the second tissue surface; and a central portion disposed between the first apposition portion and the second apposition portion, the central portion defining a lumen therethrough; and a covering material disposed on at least a portion of the central portion, the covering material being configured to allow material flow through the lumen and between the first body conduit and the second body conduit, wherein said frame has a contracted configuration and an expanded configuration; said medical device being characterized in that the elongate member is a single continuous member that forms an individual wire loop of the first apposition portion, traverses the central portion along a helical path in a direction away from the first apposition portion and toward the second apposition portion, forms an individual wire loop of the second apposition portion, traverses the central portion along a helical path in a direction away from the second apposition portion and toward the first apposition portion; and the elongate member repeats the pattern such that a plurality of wire loops of the first apposition portion and a plurality of wire loops of the second apposition portion are formed; and said central portion being formed of more than one segment which, when combined together, define a helix. a frame being formed by an elongate member, the elongate member defining: a first apposition portion including at least one wire loop configured to conform to a geometry of a first tissue surface of the first body conduit and to provide an apposition force against the first tissue surface; a second apposition portion including at least one wire loop configured to conform to a geometry of a second tissue surface of the second body conduit and to provide an apposition force against the second tissue surface; and a central portion disposed between the first apposition portion and the second apposition portion, the central portion defining a lumen therethrough; and a first apposition portion including at least one wire loop configured to conform to a geometry of a first tissue surface of the first body conduit and to provide an apposition force against the first tissue surface; a second apposition portion including at least one wire loop configured to conform to a geometry of a second tissue surface of the second body conduit and to provide an apposition force against the second tissue surface; and a central portion disposed between the first apposition portion and the second apposition portion, the central portion defining a lumen therethrough; and a covering material disposed on at least a portion of the central portion, the covering material being configured to allow material flow through the lumen and between the first body conduit and the second body conduit, wherein said frame has a contracted configuration and an expanded configuration; said medical device being characterized in that the elongate member is a single continuous member that forms an individual wire loop of the first apposition portion, traverses the central portion along a helical path in a direction away from the first apposition portion and toward the second apposition portion, forms an individual wire loop of the second apposition portion, traverses the central portion along a helical path in a direction away from the second apposition portion and toward the first apposition portion; and the elongate member repeats the pattern such that a plurality of wire loops of the first apposition portion and a plurality of wire loops of the second apposition portion are formed; and said central portion being formed of more than one segment which, when combined together, define a helix.
