Abstract: The present technology relates to systems and methods for removing a thrombus from a blood vessel of a patient. In some embodiments, the present technology is directed to systems including an elongated catheter having a distal portion configured to be positioned within the blood vessel of the patient, a proximal portion configured to be external to the patient, and a lumen extending therebetween. The system can also include a fluid delivery mechanism coupled with a fluid lumen and configured to apply fluid to at least partially fragment the thrombus, and an aspiration mechanism fluidly coupled to an aspiration lumen and configured to aspirate the fragmented thrombus.

Abstract: An apparatus, system and method for a handpiece for ocular surgical. Included may be at least: a proximal portion having at least inlet ports for irrigation tubing and aspiration tubing, and providing an irrigation fluidic pathway extending therethrough from the irrigation tubing inlet port, and an aspiration fluidic pathway extending therethrough from the aspiration inlet port; a distal portion terminating in an emulsifying tip, and providing an aspiration pathway terminating in an aspiration output, and at least one irrigation pathway terminating in at least one irrigation output; and a swivel ball provided at a base of the proximal portion and having a first opening to the irrigation fluidic pathway, and a second opening to the aspiration fluidic pathway, which seats within a socket cup provided at an upper end of the distal portion.

Abstract: In one embodiment, an irrigated medical system includes a medical tool, an irrigation line configured to fluidically connect an irrigation reservoir storing irrigation fluid to the medical tool, and provide at least some of the irrigation fluid to the medical tool, a force sensor configured to be coupled with the irrigation reservoir, and provide a signal responsively to a force exerted by the irrigation reservoir on the force sensor over time as irrigation fluid in the irrigation reservoir is depleted, and a controller configured to find an irrigation rate of the irrigation fluid flowing in the irrigation line responsively to the signal.
