Abstract: A surgical method of cataract fragmentation and extraction via microbubble cavitation is described. In particular, gas-filled microbubbles are injected into a lens capsule of a subject's eye, and cavitation of the microbubbles is activated by applied ultrasound energy. The ultrasound energy can be applied from an external device. The cavitation fragments cataract tissues without damaging other tissue, such as the lens capsule. Fragmented lens material is then aspirated from the lens capsule. The method can be used alone or in conjunction with other methods, such as phacoemulsification.

Abstract: Cleaning devices disclosed herein provide, for example, an effective and reliable approach for cleaning an exposed surface of an imaging element (e.g., a lens) of an imaging device (e.g., an endoscope). Cleaning devices disclosed herein enable an imaging element to be cleaned while located within a concealed operation site (e.g., an in-vivo surgical site). To enhance imaging device compatibility, cleaning devices disclosed herein have integral therewith a seating adjustor that allows a user to selectively adjust the position of an imaging device seated thereon. Cleaning devices disclosed herein are thus able to accommodate imaging devices that would otherwise be incompatible due to a distance between the imaging element of the imaging device and a position of a cleaning member of the cleaning device being either too big or too small.

Abstract: A delivery tool includes a tubular distal tip fixed to a distal end of a delivery tube. A retention portion of an implant wire of an implant is removably disposed within the tubular distal tip. A pull wire has a distal end portion that is shaped so as to define a pull-wire loop and is removably disposed partially within the delivery tube. A safety wire is removably disposed partially within the tubular distal tip, with a distal portion of the safety wire passing through a tip distal opening. The safety wire has a proximal end portion that is shaped so as to define a safety-wire hook hooked on the pull-wire loop. Proximal pulling on the pull wire proximally retracts the safety wire from the tip distal opening, thereby allowing the retention portion to pass through the tubular distal tip. Other embodiments are also described.
