Abstract: An implantable device grafted directly to vascular structures for high volume blood and/or fluid infusion and/or removal for such purpose as hemodialysis, apheresis, exchange transfusion, or large volume fluid infusion. The device is also adaptable to intermittent access to the venous or arterial circulations for purpose of blood sampling or giving medications. The device is comprised of an implantable fluid chamber connected to a vascular shunt which is then grafted directly to the vascular structure (e.g. artery or vein).

Abstract: An improved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as "priming". The polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, "priming" can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other.

Abstract: A limited backflow reflux valve for connection between a syringe, catheter, and bulk container of injection fluid. The reflux valve permits injection of fluid from the syringe through the catheter into the patient, and also permits refilling of the syringe from the bulk container, without disconnection of any tubing. The reflux valve also permits a limited volume of fluid to backflow from the catheter into the syringe, so that the catheter may be checked for patency, but prevents any further backflow along this path after this limited volume. Therefore, the limited backflow reflux valve not only permits injection through the catheter, but also permits both withdrawal of blood from the patient and refilling of the syringe from the bulk contrast media container, without requiring disconnection of the catheter or other tubing and without risk of contamination of the syringe or introduction of air, increasing the efficiency of the injection process, enhancing safety, and reducing waste of injection fluid.

Abstract: A device for injecting medication into a vessel wall includes a plurality of flexible tubes mounted between a multi-lumen catheter and a grommet. A push-pull wire is connected to the grommet and passed through a lumen of the multi-lumen catheter. A plurality of injectors are mounted on each of the flexible tubes.

The advancing grommet forces the flexible tubes to bow outwardly, embedding the injectors into the vessel wall. A fluid medication is then introduced through the multi-lumen catheter, into the flexible tubes and out of the injectors for infusion into the vessel wall.

Temperature and pressure readouts are provided on both the pressure regulator unit and the handpiece.

Abstract: A limited backflow reflux valve for connection between a syringe, catheter, and bulk container of injection fluid. The reflux valve permits injection of fluid from the syringe through the catheter into the patient, and also permits refilling of the syringe from the bulk container, without disconnection of any tubing. The reflux valve also permits a limited volume of fluid to backflow from the catheter into the syringe, so that the catheter may be checked for patency, but prevents any further backflow along this path after this limited volume. Therefore, the limited backflow reflux valve not only permits injection through the catheter, but also permits both withdrawal of blood from the patient and refilling of the syringe from the bulk contrast media container, without requiring disconnection of the catheter or other tubing and without risk of contamination of the syringe or introduction of air, increasing the efficiency of the injection process, enhancing safety, and reducing waste of injection fluid.
