Abstract: A precision forward-looking image-guided diagnostic and therapeutic surgical probe and needle insert for microsurgery in support of imagery, neurology, neurosurgical procedures, and ophthalmic surgical applications comprising an introducer needle (stylet), a fiber carrier, a therapeutic conduit, and a spirographic method for scanning a target and associated algorithms to create and render a reconstructed image for display to a physician in real-time or near real-time. The probe implements Optical Coherence Tomography (OCT) to provide high-resolution extended imagery of an intended therapeutic or target tissue. A separate therapeutic conduit provides surgical access for therapeutic devices such as a cutting or ablation laser, an RF electrode for locally heating tissue, a lumen for local injection of neurolytics/paralytics, placement of electrodes for neuromodulation, and deployment of a micro-endoscopic imaging tool. A third working channel supports the delivery of neurolytic and other fluids.

Abstract: An apparatus for production of French press style coffee via a process to immerse and steep coffee grounds in heated water in a non-oil-absorbing environment. Filtering a finished beverage from the steeped mixture through a microperforated non-oil-absorbing filter, where microperforations are sized to achieve sediments levels equivalent to or less than that of traditional French press, and filtration rate is enhanced via any combination of vibratory energy, air pressure, and air flow to the brewed mixture. The microperforated filter may be permanent and reusable, or may be disposable. The disposable filter is preferably made from flexible aluminum foil and recyclable. The apparatus and method support modification of filter size, microperforation size, perforation density, air pressure, air flow and vibratory action to vary beverage filtration rate and finished beverage composition.
