20100069882 | MEDICAL DEVICE WITH PREFERENTIAL BENDING - Medical devices such as catheters may provide advantages in flexibility, strength and other desired properties. Some medical devices may include a hypotube that has a plurality of slots disposed therein. The hypotube or another portion of the medical device may cause or permit the medical device to exhibit preferential bending in a single direction. | 03-18-2010 |
20110245808 | GUIDEWIRE WITH AN IMPROVED FLEXURAL RIGIDITY PROFILE - Medical devices and methods for making and using the same are disclosed. An example medical device may include a guidewire. The guidewire may include a core wire having a distal portion. A tubular member may be disposed over the distal portion. The tubular member may have a plurality of slots formed therein and may have a longitudinal axis. The tubular member may include a variably spaced slot section that has a flexural rigidity that varies from a first flexural rigidity to a second flexural rigidity. The transition from the first flexural rigidity to the second flexural rigidity may be a function of a fourth power equation. The first flexural rigidity may be in the range of about 1×10 | 10-06-2011 |

20140336620 | 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. | 11-13-2014 |
