    Abstract: A photoacoustic imaging approach identifies, concurrently with ablation therapy, an extent of the ablation by measuring and rendering a necrotic extent of treated tissue in a treatment region. Laser pulsed light directed at the treatment region induces an acoustic (ultrasound) signal for differentiating ablated tissue from its non-ablative counterpart based on a photoacoustic spectrum variation. The acoustic signal indicates a range of necrotic extent based on a quantified ablated tissue contrast and a total contrast of both necrotic and non-necrotic tissue, defined as a fraction for computing a degree of necrosis. Generation of an image indicating the degree of necrosis allows continuous or near continuous feedback for ablation therapy guidance to ensure complete and effective ablation of the proper tissue in the treatment region.

    Abstract: A prosthetic device and approach for amputee remediation addresses partial or complete replacement of digits, and leverages the use of the remaining functional digits for directing operation of the prosthetic digits. A complete prosthetic digit replaces an amputated digit from actuated movement driven by an adjacent functional digit. A partial amputation leverages residual movement from the remining digit portion as input to an actuator for amplifying the intent of the input through a motorized actuator to impart movement to the prosthetic digit. A wrist harness supports the apparatus of partial and complete prosthetic digits as a single appliance. A variable compression feature augments tension on the wrist harness to tightly engage the prosthetic appliance to the wrist to offset a gripping load on the prosthetic digits.

    Abstract: A metal-air battery and methods for generating electricity in a metal-air battery are described herein. The battery and the method includes heating an anhydrous salt to obtain a molten salt electrolyte; contacting the molten salt electrolyte to at least one cathode communicating with air; reducing air at the cathode to obtain oxygen ions for diffusing through the molten salt electrolyte; oxidizing at least one metal anode by the oxygen ions in the electrolyte thereby generating electricity and forming a metal anode oxide; and cooling at least one section of the metal-air battery for precipitating the metal anode oxide.

    Abstract: An oxygen catheter for veterinary patients includes an integrated catheter, cannula or vessel having integrated lumens for both oxygen and anesthetic such as lidocaine. The oxygen lumen extends into the trachea of the veterinary patient, often a canine, for respiratory aid. The anesthetic lumen is integrated into the same catheter as the oxygen, and terminates prior to the oxygen lumen for administering an anesthetic such as lidocaine around the soft palate to ease discomfort of the inserted catheter. The integration of the respiratory and anesthetic vessels allows a lidocaine drip to accompany the catheterized oxygen supply to medicate the tracheal, pharynx and soft palate regions from the inserted catheter along the path of the oxygen lumen to ease patient discomfort and anxiety for effective respiratory treatment while avoiding more invasive and expensive measures.

    Abstract: A surgical rongeur device has an interchangeable, locking tip at a cutting end for engageable replacement with a variety of cutting tips for facilitating sterilization and blade changes. A detachable linkage between a handle portion and an interchangeable cutting tip (tip) provides a strong connection for actuation by the handle end but allowing for tip replacement via slidable, lateral displacement of the tip. The tip includes a blade and footplate formed from an amorphous metal for longevity and strength advantages. A handle provides a lever to actuate the tip from slidable communication via the detachable linkage. An interlocking member extends longitudinally from the handle into an internal slot on the tip for locking the tip by preventing lateral movement out of alignment with the handle. The aligned tip is responsive to actuation from the handle via a rail for disposing the blade longitudinally against the footplate.
