Abstract
Abstract Connectors are provided for making connections between tubular conduits in medical procedures such as those involving treatment of a patient's circulatory system. The connectors are variously configured for making end-to-side or end-to-end connections of tubular conduits. One of the tubular conduits may be a graft conduit, which can be artificial conduit, natural conduit, or a combination of both. The connectors for making end-to-side connections can be generally T-shaped or L-shaped. Various portions of the connectors can attach to the inside or outside of the associated conduit, depending on the connector configuration that is selected.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
The method of installing a tubular graft connector in a patient's tubular body structure through an aperture in a side wall of the tubular body structure comprising the steps of: deploying a longitudinal member so that it extends through the aperture and along the tubular body structure; moving a dilator along the longitudinal member so that the dilator enlarges the aperture; inserting a tube through the aperture enlarged by the dilator; passing the connector substantially coaxially along the tube so that a second section of the connector extends substantially coaxially along the interior of the tubular body structure and a first section of the connector extends out of the tubular body structure via the apertures; positioning the tube relative to the second section so that the second section is not within the tube; and annularly expanding the second section so that it bears on the interior of the side wall of the tubular body structure substantially coaxially inside that body structure adjacent to the aperture.
Claim 2
Independent Claim
165 words
The method of installing a tubular graft connector in a patient's tubular body structure through an aperture in a side wall of the tubular body structure comprising the steps of: deploying a longitudinal member so that it extends through the aperture and along the tubular body structure; moving a dilator along the longitudinal member so that the dilator enlarges the aperture; inserting a tube through the aperture enlarged by the dilator; passing the connector substantially coaxially along the tube so that a second section of the connector extends substantially coaxially along the interior of the tubular body structure and a first section of the connector extends out of the tubular body structure via the apertures; positioning the tube relative to the second section so that the second section is not within the tube; and annularly expanding the second section so that it bears on the interior of the side wall of the tubular body structure substantially coaxially inside that body structure adjacent to the aperture.
Claim 3
Dependent Claim
22 words
The method defined in claim 1 wherein the moving causes the dilator to enter the aperture from outside the tubular body structure.
Claim 4
Dependent Claim
22 words
The method defined in claim 1 wherein the inserting causes the tube to enter the aperture from outside the tubular body structure.
Claim 5
Dependent Claim
24 words
The method defined in claim 1 where the passing causes the connector to enter the tubular body structure from outside the tubular body structure.
Claim 6
Dependent Claim
17 words
The method defined in claim 3 further comprising: withdrawing the tube from the aperture after the passing.
Claim 7
Dependent Claim
17 words
The method defined in claim 1 further comprising: removing the dilator from the aperture after the inserting.
