Abstract: A vascular therapy device (10) includes a catheter (12) including at least one optical fiber (18) with a light output aperture (20). A containment sheath (14) has a sheath opening (13) disposed at an end thereof. The catheter is disposed inside the containment sheath and movable relative to the containment sheath to extend the light output aperture beyond the sheath opening such that the light output aperture is outside of the containment sheath. A safety sensor (22) is configured to detect whether the light output aperture is in a safe zone inside the containment sheath.

Abstract: An electrosurgical device is provided that includes a probe extending in a longitudinal direction and having a proximal region and a distal region. An inner diameter of the probe defines a lumen. The probe has an electrically insulated portion extending from the proximal region to the distal region and an electrically exposed conductive portion located at the distal region. The electrically exposed conductive portion delivers radiofrequency energy to an area of tissue adjacent the distal region. The device also includes a heat transfer system for removing thermal energy from the area of tissue that is in thermal contact with the area of tissue. The heat transfer system removes from about 0.1 Watts to about 50 Watts of energy from the tissue. In addition, the heat transfer system can sufficiently draw heat away from the tissue without the use of a peristaltic pump for circulating a liquid inside the lumen.
