  • Composite guidewire withdrawn and filled tube construction
    Patent number: 8226577
    Abstract: The present invention is directed to an intracorporeal device, preferably a guidewire, and method for making the device. The guidewire of the present invention is formed, at least in part, of a composite elongate core formed, at least in part, of precipitation hardened material. The elongate core members of the present invention will have an ultimate tensile strength and modulus of elasticity greater than the same for an identically dimensioned elongate member formed from superelastic NITINOL alone.
    Type: Grant
    Filed: September 4, 2009
    Date of Patent: July 24, 2012
    Assignee: Abbott Cardiovascular Systems Inc.
    Inventors: Marc M. Jalisi, David M. Anderson, Wayne E. Cornish, Nancy A. Nicotra, Mark T. Richardson

  • NiTi alloyed guidewires
    Patent number: 6352515
    Abstract: The present invention is directed to an intracorporeal device, preferably a guidewire, and method for making the same. The device, has proximal and distal ends and includes an elongated high strength proximal portion having proximal and distal ends. The device further includes a distal portion having proximal and distal ends. The distal end of the proximal portion and the proximal end of the distal portion are connected by a connector. The distal portion is formed of a superelastic alloy composition. Preferably, the connector is also formed of the superelastic alloy composition. The superelastic alloy composition includes, in atomic percent, from about 28 to about 52% nickel, from about 48 to about 52% titanium, and up to about 20% of at least one alloying element selected from the group consisting of palladium, chromium, and hafnium.
