Abstract
An optical beam is delivered to internal target tissue, for example via two counter-rotating disks or via a single rotatable component. In one approach, two counter-rotating disks deflect an incident optical beam in a manner that generates an irradiation pattern at the target tissue. In another approach, a rotatable component includes a plurality of deflection sectors arranged around a rotation axis, and each sector deflects an incident optical beam as the sector rotates through the beam to generate an irradiation pattern at the target tissue. A probe maintains an optical channel within the human body so that the deflected optical beam can be delivered to the target tissue.
Claims31
An apparatus for achieving beneficial effects in a target tissue within a human body, the apparatus comprising:
- an optical pattern generator for directing an optical beam to generate a predetermined irradiation pattern at the target tissue, the irradiation pattern creating a plurality of microscopic treatment zones separated by untreated target tissue;
- and
- a probe for maintaining an optical channel within the human body for delivering the optical beam to the target tissue.
A method for achieving beneficial effects in a target tissue within a human body, the method comprising:
- generating an optical beam;
- directing the optical beam to generate a predetermined irradiation pattern at the target tissue, the irradiation pattern creating a plurality of microscopic treatment zones separated by untreated target tissue;
- maintaining an optical channel within the human body;
- and
- delivering the optical beam to the target tissue via the optical channel.
