US Patent:

6390993, May 21, 2002

Filed:

Dec 1, 1998

Appl. No.:

09/203140

Inventors:

Wayne E. Cornish - Oceanside CA
John Schreiner - Hemet CA
James Jacobs - Mountain View CA
Marc M. Jalisi - Temecula CA
Mark Richardson - Escondido CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61B 500

US Classification:

600585, 604525

Abstract:

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.

International Classification:

A61B 500

US Classification:

600585

Abstract:

A guidewire for guiding a medical device within a patient which has an elongate core member with a flexible body member disposed about and secured to a distal core section and a flexible core segment or flexible core segment which has a first pair of opposed faces which define a first transverse dimension that tapers from a first value to a second larger value and a second pair of opposed faces which define a second transverse dimension that tapers from a first value to a second smaller value.

International Classification:

A61B 500

US Classification:

600585

Abstract:

The invention is directed to a system and method of encoded markings on the body of medical devices such as guide-wires having limited surface for markings. The markings include indicators of characteristics, such as the design family, the size, and other pertinent specifications. The marking system of the invention comprise an spatially ordered series of marks on the surface of the device, with each mark corresponding to an information or data category. Each mark is coded with a value of the code property which is correlated with and expresses a particular data element within the data category and pertinent to the marked device specimen. The code property value may then be inspected or âreadâ by the device user to evaluate the data element and obtain information regarding the marked device specimen.

International Classification:

A61B 5/00

US Classification:

600585, 604524, 604526, 600434

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.
