Abstract: A two-piece graft connector having a tubular band section with its proximal end configured to attach to a tubular graft and retention loops extending from its distal end, and a tubular anchor structure configured to be placed in the patient's tubular body tissue structure is provided. In a preferred embodiment, the proximal end of the tubular band section is attached to a tubular graft. The retention loops extend from the distal end of the tubular band section of the connector, through an aperture in the side wall of a patient's tubular body tissue structure. The tubular anchor structure is placed in the patient's tubular body tissue structure, within the retention loops. Then, the tubular anchor structure is circumferentially expanded, firmly retaining the retention loops, and forming a seal between the tubular band section and the side wall of the tubular body tissue structure. Alternatively, the retention loops may be replaced by retention fingers, which form arcs.

Abstract: Connectors are provided for attaching flexible tubular grafts to the body organ tubing of a patient at oblique angles. The connector structures may be formed from two elongated members connected by a series of struts. Wire hooks welded to the connector may be used to engage the graft and the body organ tubing when the connector is used to attach the graft to the body organ tubing. The struts are bendable so that the elongated members can be compressed toward each other when it is desired to install a graft by placing the graft and the connector in a delivery tube. When the connector and graft are released from the delivery tube at the installation site, at least the open end of the connector adjacent to the body organ tubing has an oval shape for insertion into and attachment to an oval aperture in the body organ tubing.

Abstract: A tubular artificial graft for attachment to a patient's tubular body tissue has an initially radially relatively small connector structure adjacent each of its ends. The initial relatively small size of each connector structure facilitates insertion of that portion of the graft into the body tissue to which that connector structure is to make a connection. After a connector structure is properly positioned relative to the body tissue, the connector structure is radially enlarged to connect the graft to the body tissue. The connection is preferably both a mechanical and a fluid-tight connection.

Abstract: A bodily fluid filter has an elastic tubular framework and a plurality of filter filaments extending from the surface of the tubular framework in toward the longitudinal axis to trap objects to be filtered. The elastic framework is deformable to facilitate deployment and removal, but resumes its operational shape once deployed. The filter can be installed intralumenally and/or remotely if desired.
