Medical grafting methods and apparatus
First Claim
1. A method of installing tubular graft conduit between first and second spaced locations in a patient'"'"'s tubular body structure, comprising:
- providing an aperture through a wall of the tubular body structure at the first location with a distal portion of an elongated structure inserted into and along a lumen of the tubular body structure to the first location;
providing a graft;
providing first and second connectors;
attaching the first and second connectors to axial ends of the graft;
passing the graft along the lumen of the tubular body structure through the wall at one of the first and second locations to the other of the locations;
annularly expanding a first axial portion of the first connector spaced furthest from the first location;
inserting a second axial portion of the first connector into the tubular body structure at the first location such that the first, expanded portion of the first connector remains outside the tubular body structure; and
annularly expanding the second axial portion of the first connector positioned inside the tubular body structure at the first location.

Abstract
Methods and apparatus for making an anastomotic connection between first and second tubular fluid conduits are provided. For example, a connector may be configured for attachment to the first and second tubular fluid conduits and have an interior thereof substantially accessible to the interior of the first tubular fluid conduit. The connector may be configured for annular enlargement. An expandable structure is provided having a first portion configured to annularly enlarge the connector by engaging the interior of the connector. A second portion may be configured to extend through an opening in the medial portion of the first tubular fluid conduit.
