Abstract (en)
[origin: WO0178801A2] Devices and methods for placing a conduit in fluid communication with a target vessel to communicate the target vessel with a source of blood. A conduit is coupled to the target vessel by first and second securing components that compress or sandwich the vessel wall. The conduit may be preshaped to assume a desired orientation when in an unbiased state, for example, to allow the conduit to be deformed during delivery and then regain its desired orientation once deployed. The first and second securing components may be any shape but are preferably elongated in the direction of the vessel axis, e.g., elliptical or rectangular, such that a minimum amount of material is present at the outlet to closely approximate the cross-sectional area of the native target vessel. The securing components do not significantly occlude the target vessel lumen, may be secured to the vessel wall in non-penetrating fashion, and provides a fluid-tight seal around the attachment site. The conduit may comprise tissue, synthetic material, etc., and one or both securing components may be constructed or provided with means for attaching an outologous vessel.
[origin: WO0178801A2] Devices and methods for placing a conduit (10) in fluid communication with a target vessel (TV) to communicate the target vessel (TV) with a source of blood. A conduit (10) is coupled to the target vessel (TV) by first (14) and second (16) securing components that compress or sandwich the vessel wall. The conduit (10) can be preshaped to assume a desired orientation when in an unbiased state, for example, to allow the conduit (10) to be deformed during delivery and then regain its desired orientation once deployed. The first (14) and second (16) securing components may be any shape but are preferably elongated in the direction of the vessel axis, e.g., elliptical or rectangular, such that a minimum amount of material is present at the outlet to closely approximate the cross-sectional area of the native target vessel. The securing components (14, 16) do not significantly occlude the target vessel lumen, may be secured to the vessel wall in non-penetrating fashion, and provides a fluid-tight seal around the attachment site. The conduit (10) may comprise tissue, synthetic material, etc., and one or both securing components may be constructed or provided with means for attaching an outologous vessel.
