Title:
LASER THERAPY APPARATUS, LASER THERAPY SYSTEM AND ASSESSMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2012/098623
Kind Code:
A1
Abstract:
[Problem] To provide a laser therapy apparatus, a laser therapy system and an assessment method capable of assessing the state of laser catheter contact including how far the tip is embedded in the tissue. [Solution] The invention has: a connecting part (210) to which the second end of a laser catheter (300) connects, the laser catheter having a first end and a second end, emitting and admitting laser light from the apical surface of the first end, and having electrodes that are provided along the axial direction of the first end on the outer circumference of the first end; an emission unit (110) that emits laser light to the second end that is connected to the connecting part; an optical state-detecting unit (130) that admits returning light from the second end that is connected to the connecting part and detects the optical state of the admitted returning light; an electrical state-detecting unit (135) that detects the electrical state of the electrodes via the second end that is connected to the connecting part; and an assessing unit (150) that assesses, on the basis of the detected optical state and electrical state, the state of contact with the tissue to be treated using the first end and the laser catheter.
