Medical grafting methods and apparatus
First Claim
1. Apparatus for making an anastomotic connection between a tubular graft conduit and a patient'"'"'s tubular body structure at first and second spaced locations comprising:
- first and second connectors attached to the axial ends of the tubular graft conduit and having interior portions substantially accessible to the interior of the tubular graft conduit, a portion of the first and second connectors configured for annular expansion; and
first installation structure having a first expandable portion for annularly expanding a portion of the first connector by engaging the interior of the first connector and a first elongated structure for remotely controlling expansion of the first expandable member, the first installation structure having an axial opening extending therethrough;
second installation structure having a second expandable portion for annularly expanding a portion of the second connector by engaging the interior of the second connector and an second elongated structure for remotely controlling expansion of the second expandable member, a portion of the second installation structure extending coaxially through the axial opening in the first installation structure, wherein the first and second installation structures are remotely controllable from outside the patient;
an elongated structure configured for passage into and along the inner lumen of the patient'"'"'s tubular body structure to the first location, wherein the elongated structure defines an interior configured to receive the tubular graft; and
a balloon structure for selectively enlarging an opening at the second location, the balloon structure having an internal lumen for coaxial advancement over the longitudinal member.

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.
