Abstract: A device and method are provided which achieve tissue ablation as well as tissue coagulation substantially simultaneously during the treatment of BPH by utilizing at least two wavelengths of light. The device and method improve urinary flow and minimize post-treatment blood loss and edema while maintaining a nearly blood-free operating field during treatment by irradiating substantially simultaneously with at least two different wavelengths of light. The present device and method uses optical fibers including in preferred embodiments special side emitting optical fibers to provide a practical, minimally invasive treatment of enlarged prostates. According to the present invention, tissue ablation is affected by having one wavelength that is highly absorbed in the prostatic tissue while another less highly absorbed wavelength coagulates surrounding hyperplasic tissues while maintaining minimal thermal damage to normal tissue, surrounding the hyperplasia. In a preferred embodiment the highly absorbed wavelength is about 1460 nm and the less absorbed by water but with some significant hemoglobin absorption is about 980 nm. This combination aids the patient by reducing blood loss and edema. It can aid the practitioner, especially where imaging is employed, by maintaining a substantially blood-free area during treatment.

Abstract: A sports simulation system includes a projectile tracking apparatus having a display surface on which a visually apparent three-dimensional sports scene is presented. The projectile tracking apparatus captures images of a projectile tracking region disposed in front of the display surface to detect a launched projectile traveling through the projectile tracking region towards the display surface. A projectile launch area sensing unit captures images of the projectile launch area. At least one processing stage communicates with the projectile tracking apparatus and the projectile launch area sensing unit and is responsive to the data received therefrom to determine the three-dimensional positions, velocity, acceleration and spin of a detected projectile traveling through the projectile tracking region. The determined three-dimensional positions, velocity, acceleration and spin are used by the at least one processing stage to calculate a trajectory of the launched projectile into the visually apparent three-dimensional sports scene. Updated image data is generated by the at least one processing stage that includes a simulation of the launched projectile into the visually apparent three-dimensional sports scene following the calculated trajectory. A projection unit coupled to the at least one processing stage receives the image data from the at least one processing stage and presents the visually apparent three-dimensional sports scene, including the simulation, on the display surface.
