Abstract: Provided herein are methods of analyzing tissue using a magnetic resonance imaging (MRI) compatible tissue analysis device that includes radio-frequency (RF) tracking and imaging elements. Related kits, systems, and computer program products are also provided.

Abstract: Provided is a fluid delivery device for delivering at least two fluids, the device comprising: a first fluid pathway having a first upstream large volume and a first downstream small volume connected in fluid communication with the first upstream large volume, the first fluid pathway further comprising a first exit; a second fluid pathway having an second upstream large volume and a downstream second small volume connected in fluid communication with the second upstream large volume, the second fluid pathway further comprising a second exit; and an insertion member containing the first and second exits in a closely proximate relationship and configured to insert the first and second exits through tissue to a distribution location without prior mixing of the fluids. Also provided is a kit containing the fluid delivery device, methods of using the fluid delivery device, and methods of manufacturing the fluid delivery device.

Abstract: An exemplary robotic needle insertion system is disclosed that can provide respiration compensated needle insertion for an accurate and efficient ablation, biopsy, draining placement of a needle, among other surgical procedures. The system employs a robotic instrument comprising (i) a needle insertion mechanism configured to deliver the needle insertion in a step-wise manner that mimics the current clinical practice by inserting the needle (e.g., RFA needle) according to respiration and other motion and (ii) a probe manipulation mechanism to direct an ultrasound probe to provide intraoperative image guidance for the needle insertion.

Abstract: A substantially metallic magnetic resonance Imaging (MRI)-tracked injection needle device is disclosed. The magnetic resonance Imaging (MRI)-tracked injection needle device includes a luer syringe; an electrical connector that is at least partially housed in an interior space of a distal end of the luer syringe; an electrical adaptor coupled to the electrical connector; and an injection needle comprising a shaft having a needle distal end and a needle proximal end, the shaft comprising concentric metal tubes comprising an inner metal tube and an outer metal tube, the needle proximal end coupled to the electrical adaptor and the needle distal end comprising one or more tracking coils arranged between the inner metal tube and the outer metal tube.

Abstract: Migration of suspended materials in nail enamels is prevented by the addition thereto of from about 0.10 to 5.0% by weight of a phosphatide such as lecithin. Settling and migration of suspended materials in nail enamels is prevented by the addition thereto of from 0.10 to 5.0% by weight of a phosphatide such as lecithin and from about 0.04 to 0.20% by weight of a cosmetically acceptable acid.
