Abstract
Abstract Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
A method for deploying a conduit in a target vessel, the method comprising steps of: (a) providing a conduit having a first end, a second end and a lumen, wherein the conduit is movable between deployed and non-deployed positions and at least a portion of the conduit is held in the non-deployed position by a retention member, the retention member comprises a sheath that overlies the non-deployed portion of the conduit, wherein the conduit comprises a stent and the deployed and non-deployed positions correspond, respectively, to expanded and collapsed orientations of the stent; (b) positioning at least the non-deployed portion of the conduit in a lumen of a target vessel; (c) moving the retention member in a first direction with respect to the conduit to move the non-deployed portion of the conduit to the deployed position, the retention member moving distally toward the target vessel; and (d) moving the retention member in a second direction that is substantially opposite the first direction to remove the retention member from the target vessel, the retention member moving proximally away from the target vessel, wherein the sheath is removed through the lumen of the deployed portion of the conduit; and coupling the sheath to a sheath removal mechanism and removing the sheath and the sheath removal mechanism from the target vessel.
Claim 2
Independent Claim
218 words
A method for deploying a conduit in a target vessel, the method comprising steps of: (a) providing a conduit having a first end, a second end and a lumen, wherein the conduit is movable between deployed and non-deployed positions and at least a portion of the conduit is held in the non-deployed position by a retention member, the retention member comprises a sheath that overlies the non-deployed portion of the conduit, wherein the conduit comprises a stent and the deployed and non-deployed positions correspond, respectively, to expanded and collapsed orientations of the stent; (b) positioning at least the non-deployed portion of the conduit in a lumen of a target vessel; (c) moving the retention member in a first direction with respect to the conduit to move the non-deployed portion of the conduit to the deployed position, the retention member moving distally toward the target vessel; and (d) moving the retention member in a second direction that is substantially opposite the first direction to remove the retention member from the target vessel, the retention member moving proximally away from the target vessel, wherein the sheath is removed through the lumen of the deployed portion of the conduit; and coupling the sheath to a sheath removal mechanism and removing the sheath and the sheath removal mechanism from the target vessel.
Claim 3
Dependent Claim
22 words
The method of claim 1 , wherein the sheath and the sheath removal mechanism are removed through the lumen of the conduit.
Claim 4
Dependent Claim
33 words
The method of claim 1 , further comprising providing the sheath removal mechanism with a tapered portion that is coupled to the sheath and forms a smooth outer profile for removing the sheath.
Claim 5
Dependent Claim
27 words
The method of claim 1 , wherein the portion of the conduit is secured to the target vessel without using suture to form a substantially suture-free anastomosis.
Claim 6
Independent Claim
139 words
A method for placing a conduit in fluid communication with a target vessel so as to preserve native flow through the target vessel, the method comprising steps of: (a) providing a vessel coupling and a conduit, wherein the vessel coupling has a first portion configured to secure the conduit to a target vessel so that the conduit is in fluid communication with the target vessel; (b) moving the vessel coupling generally along a first direction to place the first portion of the vessel coupling at least partially within the lumen of the target vessel; and (c) moving the first portion of the vessel coupling generally along a second direction within the lumen of the target vessel to deploy the vessel coupling and secure the conduit to the target vessel, wherein the second direction is transverse to the first direction.
Claim 7
Independent Claim
139 words
A method for placing a conduit in fluid communication with a target vessel so as to preserve native flow through the target vessel, the method comprising steps of: (a) providing a vessel coupling and a conduit, wherein the vessel coupling has a first portion configured to secure the conduit to a target vessel so that the conduit is in fluid communication with the target vessel; (b) moving the vessel coupling generally along a first direction to place the first portion of the vessel coupling at least partially within the lumen of the target vessel; and (c) moving the first portion of the vessel coupling generally along a second direction within the lumen of the target vessel to deploy the vessel coupling and secure the conduit to the target vessel, wherein the second direction is transverse to the first direction.
Claim 8
Dependent Claim
53 words
The method of claim 5 , wherein the first direction corresponds to the longitudinal axis of the conduit and the second direction corresponds to the longitudinal axis of the target vessel, and step (c) is performed by moving the first portion of the vessel coupling along a curved path between the two axes.
