Abstract: A prostate treatment system having a light delivery device positionable in a transurethral device for treatment of benign prostatic hyperplasia (BPH). The light delivery device includes light generator, such as light emitting diodes (LED), laser diodes (LDs) or a diffusion quartz fiber tip connected to a light generator or a light emitting polymer which produces light at a selected wavelength or waveband or alternative sources of suitable light energy. The treatment device may further include a temperature monitoring system for monitoring the temperature at the treatment site. A light-activated drug is administered to the treatment site prior to light activation. The light-activated drug therapy induces cell death of the target tissue. The device provides a minimally invasive transurethral method for treatment of BPH or prostate cancer.

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).

Abstract: A method and apparatus for screening or sensing disease states, injury sites or bodily conditions in a human or animal subject by separately detecting the DC biopotential of the electromagnetic field at a plurality of test points in a test area. The DC biopotentials are converted by analog to digital converters connected to DC biopotential test sensors at the test points into digital test signals, and the DC biopotential test sensors and analog to digital converters form a biopotential sensing section which is separate from a processing section that receives and processes the digital test signals. Signals between the processing section and the bopotential sensing section are transmitted by a transmission network which electrically isolates the two sections.
