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: 8613712Abstract: A guide wire for advancing a medical device such as a catheter through a patient's body lumen which has an elongated core with proximal and distal core section, a flexible tubular member such as a coil on the distal end. The wire core includes surface textures that are translated into the overlying coating. Alternatively, the coating has its own surface texture. The surface textures include randomly or non-randomly spaced bumps, divots, ridges, helical grooves, longitudinal grooves, undulations, etc.Type: GrantFiled: September 16, 2003Date of Patent: December 24, 2013Assignee: Abbott Cardiovascular Systems Inc.Inventors: David H.

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: 8123702Abstract: 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: March 11, 2008Date of Patent: February 28, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventors: Ryan Grandfield, Mark T.

Publication number: 20070123930Abstract: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The expandable frame and filtering element can be mounted on a filter support structure, such as a coiled wire, and mounted on a guide wire. The expandable frames includes an articulation region which helps to distribute the strain which can be developed when the frame moves between an expanded and deployed position. The expandable frame may include further strain distributing bends which help distribute strain and increase the bendability of the frame.Type: ApplicationFiled: January 11, 2007Publication date: May 31, 2007Inventors: Scott Huter, John Papp, Douglas Gesswein, Wayne Cornish, Peter D'Aquanni, Thomas Tokarchik, Andy Denison, Kevin Magrini, Benjamin Huter, Charles Peterson, William Boyle, Mark Richardson, Ryan Grandfield, Kathern Lind
