  • Patent number: 4922905
    Abstract: Mounted on the catheter is an endoprosthesis which can be inserted into a vessel, for example, in a predetermined position, radially expandable, implantable at the expansion site, where it is subsequently retained in place. The endoprosthesis can encompass a section of the catheter by its own radial tension and can thereby be retained in an essentially fixed position, without axial play, while its separation from the catheter is effected by radial expansion during implantation. The endoprosthesis may, however, also be mounted on the catheter in an essentailly fixed position, without axial play, by mechanical means ceasing to be effective after the implantation because of radial expansion, or which can be eliminated after the implantation so as to enable the catheter to be withdrawn.

  • Patent number: 4921479
    Abstract: An improved removable expandable sheath for aiding in the introduction of catheters into the body which is fabricated from a semi-stiff plastic with memory formed in a tubular configuration with a longitudinal slit or non-joined seam extending along the entire length of the sheath and where the tubular structure with slit is coiled about its longitudinal axis so that its tubular wall overlaps itself in its native state. On exertion of an internal force directed outward, the tubular sheath enlarges its effective diameter by uncoiling to the extent necessary to accommodate a catheter inserted therein. The memory inherent in the material of the sheath keeps the wall of the sheath snugly around the catheter to afford guidance of the catheter into a blood vessel.

  • Patent number: 4911706
    Abstract: An automatic needle cover is mounted onto the base of a hypodermic needle on a syringe and leaves the needle exposed for initial use, such as for withdrawing blood or the like. A releasable tab is either cut or released, and a resilient support arm pushes a protective cap out past the end of the needle, to cover the end of the needle and prevent an accidental pricking of the user's skin. The contents of the syringe can drip freely out of the cap, or if desired, the cap can be braced against a depression in a rubber stopper of a container, to thereby facilitate realigning the hole in the cap with the needle, so that the needle contents can be discharged into the container. The protective cap is made so that it moves laterally to insure covering the point of the needle so that the point will not accidentally protrude.
