Apparatus and methods are provided for closing a tubular structure within a patient's body. The apparatus includes a needle including a proximal end including a hub, a distal end including a sharpened distal tip, a lumen having an oblong cross-section extending proximally from the distal end, and defining a longitudinal axis between the proximal and distal ends, and a clip deliverable from the lumen. The clip is compressible between a relaxed state in which a plurality of tines of the clip are shaped to engage and close a tubular structure within a patient's body, and a stressed state in which the tines are compressed to allow the clip to be loaded into the. The apparatus may also include a pusher member for deploying the clip from the distal tip of the needle such that the tines engage and close a tubular structure through which the tubular member is directed.

A self-sealing tubular graft is provided for implantation within a patient's body that includes an elongate tubular body including first and second self-sealing cannulation regions and a loop region extending between the first and second cannulation regions. The loop region includes one or more reinforcement members attached to a first length of the loop region and extending at least partially around a circumference of the tubular body. For example, the reinforcement members may include one or more sinusoidal or zigzag members extending along the first length with alternating peaks and valleys extending at least partially around a circumference of the tubular body. Self-sealing patches are also provided that include one or more reinforcement members embedded within base material.

A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable laterally within a plane of the base material to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return laterally towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch or integrally attached to a tubular graft or in various shapes.

A heart valve assembly includes an annular prosthesis and a plurality of guide shields removably attached around a circumference of the annular prosthesis. A plurality of elongate guide rails extend from the annular prosthesis, which are releasably retained by the guide shields. During use, the annular prosthesis is directed into a biological annulus, e.g., with the guide rails retained by the guide shields, and secured to tissue surrounding the biological annulus using fasteners. The guide rails are released from the guide shields, and a valve prosthesis is advanced over the leaders and through a passage defined by the guide shields towards the annular prosthesis. The guide rails may include retentions elements that secure the valve prosthesis to the annular prosthesis. The guide shields are removed from the annular prosthesis, the guide rails are separated from the annular prosthesis, and are removed from the biological annulus.

A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness comprises a plurality of spaced apart conductive panels arranged so that there is no electrical continuity circumferentially around the harness. In an additional embodiment, a cardiac harness is provided that is insulated so as not to conduct electricity circumferentially about the harness.
