    Abstract: A device for general and selective angiography and other purposes having a handle, controllable tip guide body, injection tube unit and catheter outer body wherein the tip of the guide body may be bent, rotated, exposed and sheathed in the catheter by control means on the handle and injection tube unit, and locked in selected position, the several parts being usable as a complete assemblage and in different combinations. The guide body is made torsionally rigid so that the rotation of the tip corresponds to the manipulation of a rotator on the handle, the guide body rotating within the catheter outer body which is nonrotatable. The guide body extends through the injection tube unit which is interposed between the handle and the catheter outer body. The injection tube unit has a sliding telescoping part for extending the catheter outer body to sheath the guide body and for retracting the catheter outer body to unsheath the tip of the guide body. For certain purposes the injection tube unit and catheter outer body may be removed and the guide body and handle used together as an operative unit. Also, the guide body is conveniently removable from the handle.

    Abstract: This invention relates to an implant device. It is well known in the art that there are various methods for externalizing an internal vessel, or providing fluid communication from the vascular system to a cleansing source outside the body. In the former, the ulceration of the skin, and in the latter the trauma of connecting and reconnecting arteries and veins with tubes or needles have proved to be serious problems. The present invention seeks to do away with these problems by providing an implant device which connects to an implantable connector in order to provide access to the body conduit or vessel external from the body. The implant device has a passageway, which is either straight or curved at the outlet, an anchor means for establishing a biological anchor, and a grafting mesh annularly and longitudinally diposed about, and longitudinally spaced apart from, at least a portion of the exterior of said implant device whereby tissue is permitted to grow between the exterior of the device and the mesh. The passageway, anchor means and grafting mesh are formed from a material selected from the group comprising pyrolytic carbon disposed on a graphite substrate and vitreous carbon.

    Abstract: This invention relates to a connector to replace a portion of a patient's internal body fluid or solid carrying conduit adapted to connect said body conduit to a vascular implant device for providing external access to said body conduit. It is well known in the art that there are various methods for externalizing an internal vessel, or providing fluid communication from the vascular system to a cleansing source outside the body. In the former, the ulceration of the skin, and in the latter the trauma of connecting and reconnecting arteries and veins with tubes or needles have proved to be serious problems. The present invention seeks to do away with these problems by providing a body implantable connector to replace a portion of a patient's body fluid or solid carrying conduit, said connector adapted to connect device to the body conduit or vessel external from the body. The connector includes a tubular member expanded along its length in order to form a bulbous portion; a side port is provided for connection to the implant device at the approximate midpoint of the tubular member bulbous portion.
