Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
137 words
A method for making an anastomotic connection between a first tubular fluid conduit and a second tubular fluid conduit in a patient, the method comprising: attaching a connector to an axial end of the first tubular fluid conduit such that an interior portion of the connector is substantially accessible to an interior lumen of the first tubular fluid conduit, wherein the attaching comprises: providing members on the connector having free end portions that are directed radially outward; and piercing the axial end portion of the first tubular conduit at annularly spaced locations; passing a portion of the connector through an opening in the side wall of the second tubular fluid conduit; and expanding a portion of the connector by accessing the interior of the connector through an opening in the side wall of the first tubular conduit.
Claim 2
Independent Claim
137 words
A method for making an anastomotic connection between a first tubular fluid conduit and a second tubular fluid conduit in a patient, the method comprising: attaching a connector to an axial end of the first tubular fluid conduit such that an interior portion of the connector is substantially accessible to an interior lumen of the first tubular fluid conduit, wherein the attaching comprises: providing members on the connector having free end portions that are directed radially outward; and piercing the axial end portion of the first tubular conduit at annularly spaced locations; passing a portion of the connector through an opening in the side wall of the second tubular fluid conduit; and expanding a portion of the connector by accessing the interior of the connector through an opening in the side wall of the first tubular conduit.
Claim 3
Dependent Claim
47 words
The method defined in claim 1 , wherein the first tubular fluid conduit has a side branch located at the medial portion, and the expanding the portion of the connector comprises accessing the interior of the connector through the side branch of the first tubular fluid conduit.
Claim 4
Dependent Claim
62 words
The method defined in claim 1 , wherein the expanding the portion of the connector comprises: providing an expandable structure having a balloon member disposed adjacent the interior of the connector and an elongated portion configured to pass through the opening in the side wall of the first tubular fluid conduit for remotely expanding the balloon member; and expanding the balloon member.
Claim 5
Dependent Claim
38 words
The method defined in claim 2 , further comprising: after the expanding the portion of the connector, removing the expandable structure from the first tubular fluid conduit and closing the side branch of the first tubular fluid conduit.
Claim 6
Dependent Claim
45 words
The method defined in claim 1 , wherein the attaching further comprises engaging the side wall of the second tubular fluid conduit when a predetermined axial portion of the connector has passed through the opening in the side wall of the second tubular fluid conduit.
Claim 7
Dependent Claim
36 words
The method defined in claim 1 , further comprising: before the passing the portion of the connector through the opening in the side wall of the second tubular fluid conduit, piercing the second tubular fluid conduit.
Claim 8
Dependent Claim
40 words
The method defined in claim 6 , wherein the piercing the second tubular fluid conduit comprises piercing the second tubular fluid conduit by advancing an elongated member from the interior of the second tubular fluid conduit to the exterior thereof.
Claim 9
Dependent Claim
40 words
The method defined in claim 6 , wherein the piercing the second tubular fluid conduit comprises piercing the second tubular fluid conduit by advancing an elongated member from the exterior of the second tubular fluid conduit to the interior thereof.
Claim 10
Dependent Claim
32 words
The method defined in claim 7 , further comprising: after the step of piercing the second tubular fluid conduit, enlarging the opening in the side wall of the second tubular fluid conduit.
Claim 11
Dependent Claim
31 words
The method defined in claim 9 , wherein the enlarging the opening comprises expanding a balloon member positioned in the opening in the side wall of the second tubular fluid conduit.
Claim 12
Dependent Claim
53 words
The method defined in claim 1 , wherein the expanding a portion of the connector comprises expanding the portion of the connector disposed within the second tubular fluid conduit such that the members engage the interior side wall of the second tubular fluid conduit and the free end portions pierce the side wall.
Claim 13
Dependent Claim
82 words
The method defined in claim 11 , further comprising: providing a sheath structure configured to surround a distal portion of the connector and the free end portions, wherein the passing the portion of the connector through the opening in the side wall of the second tubular fluid conduit comprises passing the connector and the sheath structure through the opening in the side wall of the second tubular fluid conduit such that the sheath structure surrounds the free end portions during the passing.
Claim 14
Dependent Claim
40 words
The method defined in claim 12 , further comprising: after the passing the sheath structure through the opening in the side wall of the second tubular fluid conduit, moving the sheath structure to a location spaced apart from the connector.
Claim 15
Dependent Claim
94 words
The method defined in claim 1 , further comprising: attaching a second connector to a second axial end of the first tubular fluid conduit such that an interior portion of the connector is substantially open to an interior lumen of the first tubular fluid conduit; passing a portion of the second connector through an opening in the side wall of a third tubular fluid conduit; and expanding a portion of the second connector by accessing the interior of the second connector through the opening in the side wall of the first tubular fluid conduit.
