Patent number: 8628502Abstract: A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at least one location. The narrowed portion of the tube decreases the volume and velocity between the arterial and venous side of the patient to prevent damage or intimal hyperplasia on the venous side between dialysis treatments. When the valve is opened for dialysis, an unrestricted blood flow exists between the arterial and venous side, permitting a controlled, open blood flow during dialysis.Type: GrantFiled: August 5, 2011Date of Patent: January 14, 2014Assignee: INTERRAD Medical, Inc.Inventors: Timothy J. Claude, Edward A. Barlow, David W. Hunter, Michael S. Rosenberg

Patent number: 8394066Abstract: Some embodiments of a medical anchor device include an elongate body coupled with deployable subcutaneous anchors to secure a catheter instrument (or other medical instrument) in place relative to a skin penetration point. In some circumstances, the elongate body may be in the form of catheter hub body, and the subcutaneous anchors can be deployed from the hub body by adjustment of a movable actuator. A locking member can interact with the actuator so as to retain the actuator in the deployed orientation during the medical procedure.Type: GrantFiled: March 2, 2012Date of Patent: March 12, 2013Assignee: INTERRAD Medical, Inc.Inventors: Michael S. Rosenberg, Mark R. Christianson, Kyle P. Taylor, Andrew T. Forsberg, Edward A. Barlow

Patent number: 5492532Abstract: A balloon consisting of braided fibers encapsulated between two plastic elastomeric materials affixes to a distal end of a catheter. The braided fibers provide reinforcement to contain pressure and determine the maximum diameter of the balloon on expansion. The elastomeric material provides for fluid containment and collapsing of the balloon after pressurization. An embedded spring in an elastomeric material internal to the catheter provides memory to assist in collapsing the balloon after pressurization. The embedded spring extends from the distal end of the catheter towards the proximal end of the catheter along a substantial length of the catheter. The catheter with the balloon are in a multilumen configuration or in a coaxial configuration. A guidewire passage extends through the elastomeric material with the embedded spring. An alternative embodiment illustrates a hub with a movable internal seal and inner tube connected to a balloon catheter tip with a free space collapsement spring.Type: GrantFiled: August 15, 1994Date of Patent: February 20, 1996Assignee: B.

Patent number: 4946133Abstract: The hemostasis valve gasket for use in an introducer which is integrally formed from an elastomeric material so as to exhibit resiliency and which is designed to close about small diameter objects such as a guide wire and about larger diameter objects such as a working catheter or guide catheter to prevent air or blood leakage. The gasket includes a cylindrical base with a central bore therethrough and a hollow convex domed shaped member projecting therefrom. The hollow dome shaped member terminates in a concave section. The concave section of the dome shaped member has at least one arcuate slit formed in the external surface which extends inwardly toward the hollow chamber to form a central, self-sealing passage aligned with the central bore of the cylindrical base member.Type: GrantFiled: November 21, 1988Date of Patent: August 7, 1990Assignee: Schneider (U.S.A.)
