Medical grafting methods and apparatus

摘要

Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit are provided. A connector is mounted annularly around the distal end portion of an inflatable balloon. Upon inflation of the balloon, the connector enlarges radially and shortens axially such that first and second members of the connector engage the first and second conduits, respectively, and draw the two conduits together to create a seal therebetween. Additional apparatus may be provided to reduce the tension on the first conduit (e.g., a graft conduit) and/or to define a kink-free path for the first conduit to follow after making the anastomotic connection.
