Abstract: A base structure of the system with a pair of center containers each of rectangular form with a square width and height and an elongated length attached along an elongated side of each. A side container may be attached to each side of the center containers. A semicircular shaped inlet port is formed in a top wall of each of the center containers to form a circular inlet port. A vertical duct of cylindrical form may be attached over the inlet port and have a lower portion of constant diameter cross-section and an upper portion diverging outwardly. A fan placed in each center container to cause an air flow toward a center of each center container to be channeled upwardly to exit through the inlet port for air to flow through the vertical duct to exit the open top end. A recirculating air structure may be formed with additional containers.

Abstract: An apparatus and process using a high-power, short-pulsed thulium laser to output infrared laser pulses delivered through an optical fiber, for cutting and ablating biological tissue. In some embodiments, the pulse length is shortened sufficiently to keep inside the stress-confined ablation region of operation. In some embodiments, the pulse is shortened to near the stress-confined ablation region of operation, while being slightly in the thermal-constrained region of operation. In some embodiments, the laser is coupled to a small low-OH optical fiber (˜100 ?m diameter). In some embodiments, the device has a pulse duration of about 100 ns for efficient ablation; however in some embodiments, this parameter is adjustable.

Abstract: An apparatus for stimulating a neural tissue of a living subject. The neural tissue is characterized with a thermal diffusion time, Td. The apparatus includes an energy source for generating optical energy and delivering means coupled to the energy source for delivering the generated optical energy to a target neural tissue. The delivering means is configured to in operation deliver the generated optical energy with a radiant exposure that causes a thermal gradient in the target neural tissue, thereby stimulating the target neural tissue, and to deliver the optical energy in pulses with a pulse duration Tp such that Tp<Td.
