    摘要： A liquefier assembly comprising a liquefier tube, where the liquefier tube comprises a sidewall having an inlet opening configured to receive a filament strand, an outlet opening, and a port disposed through the sidewall at a location between the inlet opening and the outlet opening, the port being configured to provide access for a filament drive mechanism to engage with the received filament strand. The liquefier assembly further comprises a heat transfer component configured to generate a thermal gradient along a longitudinal length of the sidewall between the port and the outlet opening.

    摘要： A filament cassette and a filament loading assembly supply modeling filament to a liquifier in a three-dimensional deposition modeling machine. Two or more cassettes containing spooled filament are inserted into the machine. A strand of filament from a first one of the cassettes is fed to the liquifier for extrusion. Without operator intervention, the filament strand from the first cassette is withdrawn from the liquifier, and a filament strand from a second one of the cassettes is fed to the liquifier. The switching of filament feed sources is triggered by an event, such as an identification that the filament from the first cassette has reached a predetermined minimum length. In this manner, a used primary filament cassette is automatically replaced with a standby filament cassette, so that the machine need not experience downtime waiting for an operator to change the cassettes.

    摘要： Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced. The nosecone assembly has a flexible structure which may change configuration to expose the second set of members after insertion into the second conduit and to allow removal of the nosecone after deployment.

    摘要： A connector for use in providing an anastomotic connection between two tubular body fluid conduits in a patient. The connector is preferably a single, integral, plastically deformable structure that can be cut from a tube. The connector has axial spaced portions that include members that are radially outwardly deflectable from other portions of the connector. The connector is annularly enlargeable so that it can be initially delivered and installed in the patient in a relatively small annular size and then annularly enlarged to provide the completed anastomosis. The radially outwardly deflected members of the first and second portions respectively engage the two body fluid conduits connected at the anastomosis and hold those two conduits together in fluid-tight engagement. Apparatus for use in delivering and deploying a connector is also disclosed.
