Abstract
A hypotube having a laser cut wave pattern to improve flexibility. The laser cut wave pattern on the hypotube includes multiple portions that vary the pitch and angle of the cuts. The laser cut wave pattern provides flexibility while maintaining pushability further into the most tortuous vasculature. The laser cut wave pattern also provides the ability to torque the flexible hypotube back and forth, with a 1 to 1 response, without stretching the flexible hypotube. The laser cut hypotube may be used in a number of vascular or neurovascular, such as a guidewire or catheter, or delivery of a stent.
Claims20
A flexible hypotube comprising:
- an elongated body;
- multiple wave cut segments cut in the elongated body, each wave cut segment having a continuous wave cut around the elongated body forming a pattern of wave cuts configured to vary the flexibility of the elongated body by varying a distance between wave cuts and changing an angle direction between wave cut sets.
A flexible hypotube comprising:
- an elongated body;
- and
- a continuous wave cut around the elongated body forming a wave cut pattern having a pitch (distance between wave cuts) and/or an angle (direction of the wave cut) between wave cuts to provide flexibility to the elongated body.
A flexible hypotube comprising:
- an elongated body having multiple segments;
- and
- each segment having a continuous wave cut around the elongated body forming multiple segment wave cut patterns with each segment wave cut pattern having a different flexibility to provide varied flexibility to the elongated body.
