Abstract:

A photoreactive agent and a drug therapy device including a support member configured to pass through a urethra having proximal and distal ends and a longitudinal internal lumen. A light generator carried by the support member, potted within the lumen, and positioned within the urethra to deliver light to the prostate. The light generator generates a light band with a peak at a preselected wavelength. A power source external to the support member powers the light generator. The positioning element locates the support member within the urethra. A transparent/translucent, integral window is positioned proximate to the prostate and allows light to pass through. The window extends 360 degrees radially from the support member. The light generator has at least LEDs or LOs having a dimension of approximately 0.3 mm×0.3 mm×0.1 mm (length×width×thickness).
