| 20080262474 | MEDICAL DEVICE - Medical devices and methods for making and using the same. An example medical device may include an elongate shaft having a proximal region and a distal region. A tubular member may be disposed over the distal region of the shaft. The tubular member may have an outer surface and may have a plurality of slots formed therein. A coil may be disposed adjacent the tubular member. | 10-23-2008 |
| 20090036834 | ELONGATE MEDICAL DEVICE HAVING ENHANCED TORQUE AND METHODS THEREOF - An elongate medical device such as a guidewire, that may comprise a first elongate member having a proximal end, a distal end and a lumen there between, a second elongate member having a proximal end and a distal end, the second elongate member at least partially disposed in the first elongate member, a first connection between first elongate member and the second elongate member at the proximal end of the first elongate member, a second connection between the first elongate member and the second elongate member at the distal end of the first elongate member, and a third connection between the first elongate member and the second elongate member, the third connection disposed at a point between the first connection and the second connection, wherein the third connection is substantially at a location selected by the Method for Enhancing the Ratio of Torsional Stiffness to Transverse Flexibility. | 02-05-2009 |
| 20090043228 | LASER SHOCK PEENING OF MEDICAL DEVICES - A laser shock peening process for producing one or more compressive residual stress regions in a medical device is disclosed. A high-energy laser apparatus can be utilized to direct an intense laser beam through a confining medium and onto the target surface of a workpiece. An absorption overlay disposed on the target surface of the workpiece absorbs the laser beam, inducing a pressure shock wave that forms a compressive residual stress region deep within the workpiece. Medical devices such as stents, guidewires, catheters, and the like having one or more of these compressive residual stress regions are also disclosed. | 02-12-2009 |
| 20090043372 | ALTERNATIVE MICROMACHINED STRUCTURES - Medical devices and methods for making and using the same. An example medical device may include an elongate core member and a tubular member disposed about a portion of the core member. The tubular member may have a plurality of slots formed therein. The medical devices may be configured to have a preferential bending direction. | 02-12-2009 |
| 20090156999 | COIL MEMBER FOR A MEDICAL DEVICE - A coil for use in a medical device. The coil includes a plurality of coil windings or turns, wherein adjacent coil windings are connected together at a plurality of discrete connection locations to increase the torsional rigidity and torque transmitting properties of the coil without sacrificing the flexibility characteristics of the coil. In some embodiments the coil may be a wave wound coil, such as a nested wave wound coil or a crest-to-crest wave wound coil. | 06-18-2009 |
| 20090177185 | CUT TUBULAR MEMBERS FOR A MEDICAL DEVICE AND METHODS FOR MAKING AND USING THE SAME - Medical devices and methods for making and using the same. An example medical devices includes a core member and a tubular member disposed over a portion of the core member. The tubular member has a plurality of slots formed therein. | 07-09-2009 |
| 20090254000 | MICROMACHINED COMPOSITE GUIDEWIRE STRUCTURE WITH ANISOTROPIC BENDING PROPERTIES - Medical devices and methods for making and using the same. An example medical device may include an elongate core member having a proximal portion and a distal portion. The distal portion may include a distal end and a flattened region. The flattened region may be disposed proximally of the distal end. The flattened region may have a height and a width. The width may be twice or more as large as the height. A tubular member may be disposed over the distal portion. The tubular member may have a plurality of slots formed therein. | 10-08-2009 |
| 20100145308 | MEDICAL DEVICES WITH A SLOTTED TUBULAR MEMBER HAVING IMPROVED STRESS DISTRIBUTION - Medical devices and methods for making and using the same. A medical device may include an elongate tubular member. The tubular member may include a first circumferential tube segment, a second circumferential tube segment disposed next to the first circumferential tube segment, and a third circumferential tube segment disposed next to the second circumferential tube segment. The first tube segment and the second tube segment may be separated by a first set of slots formed in the tubular member. The second tube segment and the third tube segment may be separated by a second set of slots formed in the tubular member. The second tube segment may be connected to the first tube segment with a proximally-extending beam formed in the tubular member. The second tube segment may also be connected to the third tube segment with a distally-extending beam formed in the tubular member. A ring may be defined in the second tube segment between the proximally-extending beam and the distally-extending beam. The ring may have a first portion with a first width and a second portion with a second width different from the first width. | 06-10-2010 |
