Abstract

The invention discloses a Light Irradiating Unit (LIU) for providing radiant energy safely to a treatment site within the human body during treatment sessions. the LIU is comprised of the following modules: an Irradiating Array (IA) comprising LED's longitudinally disposed in a single row along a flexible support member; an external LED Controller and Power Supply (CPS); an Array Housing Catheter (AHC) for enclosing and guiding said IA to the treatment site; and a Cooling Catheter (CC) for enclosing and cooling the AHC during treatment sessions; the CC connects to a standard intra venous bag, containing cooling fluid, the is bag adapted to provide gravity induced cooling fluid flow through the CC during treatment sessions; the CC further adapted to provide drainage of the cooling fluid during said treatment sessions.

Description

Technical field [0001] The present invention relates to a device and method for safely providing radiant light energy to the treatment site in the human body, more generally, the mammalian body during treatment. Background technique [0002] The present invention generally relates to a device and method for treating a site within the human body (more generally, a mammalian body) with the radiant energy used in photodynamic therapy. Photodynamic Therapy (PDT) is increasingly used to treat tumors, as well as to destroy microorganisms and pathological changes. When PDT is used to treat malignant tumors, the photosensitive dye is injected into the patient's body at a predetermined time before the planned treatment. The photosensitive dye is activated at a wavelength that penetrates cancer cells, microorganisms or other target cells, and generates oxygen free radicals that damage the target cells. [0003] US Patent No. 5,728,090 of Martin et al. proposes an LED array mounted in a sub...
