Abstract
A vascular connector has a rough surfaced skirt which is trimmed to a size for surgical attachment, and a smooth central tube centrally extending through the skirt to a point upstream of the rough surface. A collar centrally affixed to the skirt releasably engages the tube, which in turn may be fabricated as a permanently attached input conduit of a total artificial heart. For installing the connectors, a skeletal frame fixture secures the central tubes or collars of plural connectors in defined positions corresponding to the attachment ports of the intended pump device.
