US Patent:

7572254, Aug 11, 2009

Filed:

Sep 16, 2005

Appl. No.:

11/228845

Inventors:

Chris J. Hebert - Lafayette LA, US
Wade A. Bowe - Colorado Springs CO, US
Timothy J. Wood - Monument CO, US
Scott Tedder - San Antonio TX, US

Assignee:

The Spectranetics Corporation - Colorado Springs CO

International Classification:

A61B 18/18

US Classification:

606 15, 606 13, 606 14

Abstract:

In some embodiments, without limitation, the invention comprises a catheter having an elongated housing with a channel disposed therein. A laser delivery member is movable and at least partially disposed within the channel. A ramp is disposed within the housing at an angle to its central axis and proximate to its distal end. The ramp is adapted to move the distal end of the laser delivery member outwardly from the central axis of the housing. A guidewire biases the distal end of the laser delivery member generally inwardly toward the central axis of the housing. In some embodiments, without limitation, the offset of the central axis of the tip of the laser delivery member from the central axis of the housing is determined by adjusting the extent to which the laser delivery member travels on the ramp, and disposition of the laser delivery member on the guidewire maintains the offset tip substantially parallel to the central axis of the housing. Thus, in accordance with the invention, the distal end of the laser delivery member may be biased in a desired direction or offset, permitting ablation of an area larger than the area of the distal end of the catheter.

US Classification:

606 7, 606 2, 606 13, 606 14, 606 15, 607 89

Abstract:

Embodiments of the present invention include a laser catheter that includes a catheter body, a light guide, and a distal tip that extends beyond the exit aperture of the light guide. In some embodiments, an imaging device is disposed on the distal tip such that the imaging device is distal relative to the exit aperture of the light guide. In some embodiments, the imaging device can be gated to record images during and/or slightly beyond periods when the laser catheter is not activated.
