Abstract
A device for applying light in photodynamic therapy is arranged to apply light in a pattern corresponding to the configuration of the lesion to be treated. The device may be customized in response to an image of the patient acquired before treatment. Alternatively, the device may include sensors for detecting a characteristic of tissue overlying each region of the device so that the device either emits light or does not emit light in each region depending upon the characteristics of the overlying tissue.
Claims7
A method of administering photodynamic therapy to a mammalian subject having a lesion comprising the steps of:
- (a) positioning a light-applying device capable of applying light throughout an application area over the lesion so that the application area of the device covers the lesion and also covers some normal tissue of the subject;
- (b) detecting the extent of the lesion using sensors disposed on said light-applying device;
- and
- (c) actuating the device and controlling actuating the device responsive to the detected extent to apply treating light at a treatment wavelength selectively in areas of the application area aligned with the lesion and to not apply light in areas of the application area aligned with normal tissue.
