Patent number: 8905946Abstract: A guide wire for use in a medical procedure having a shapeable tip integral with and made from the distal end of a superelastic nitinol distal section of the guide wire, wherein the shapeable tip can be finger kinked. Such a guide wire includes an elongated core made from a superelastic nitinol alloy at the distal end, the distal end of the elongated core having a tapered section leading to a shapeable distal tip. The shapeable tip is an extension of the distal end of the nitinol distal section, and includes permanent strain hardening from at least two different radial directions imparting crystallographic texture in the radial directions that eliminate superelasticity so that permanent deformation can be achieved with finger pressure.Type: GrantFiled: March 13, 2014Date of Patent: December 9, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: William J. Boyle, Wayne E. Cornish, Raleigh A. Purtzer

Publication number: 20140246407Abstract: An intravascular guide wire having two core materials joined together without the use of a connector tube or sleeve, the core materials being stainless steel and psuedoelastic metal alloy, nitinol. The core materials are joined to each other through an intermediate transition piece made essentially of nickel, which is welded on either side to the two core materials. In a multi-segment intravascular guide wire, discrete, high modulus and medium modulus core portions of different materials are welded to a shapeable, low modulus distal core portion made of a third material having a flattened, shapeable section at a most distal end that is not welded to but made from the distal core portion, so the flattened, shapeable section can be deformed to create a steerable tip. Processes such as simultaneous resistance and friction welding can be used to join the core portions.Type: ApplicationFiled: May 8, 2014Publication date: September 4, 2014Applicant: Abbott Cardiovascular Systems Inc.Inventors: John A. Simpson, Michael Plattner, Frank Manning, Ryan Grandfield, Wayne E. Cornish

Patent number: 8708933Abstract: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.Type: GrantFiled: November 12, 2012Date of Patent: April 29, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: Wayne E.

Patent number: 8308753Abstract: A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.Type: GrantFiled: February 25, 2010Date of Patent: November 13, 2012Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Douglas H.

Patent number: 8257278Abstract: A guide wire for guiding a medical device within a patient is disclosed. The guide wire has a solid inner core made of high modulus material such as Conichrome® or a rhenium alloy, and an outer shell made of a flexible, kink resistant material such as a nickel-titanium alloy. Preferably, the modulus of elasticity of the inner core material is at least about 20 percent greater than that of the outer shell material. The outer shell is mechanically joined to the inner core through a drawing or cladding process. In various embodiments, the distal end of the guide wire can be tapered by grinding away the outer shell to expose the inner core. Because of its stiffness, it can be manually shaped by the physician or cardiologist.Type: GrantFiled: May 14, 2002Date of Patent: September 4, 2012Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Jonathan M.

Patent number: 8226577Abstract: 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: GrantFiled: September 4, 2009Date of Patent: July 24, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventors: Marc M.
