The present invention relates to a medical pump for endoscopy having a pressure control unit, wherein the pressure control unit takes into account blood pressure changes of the subject.

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.

A surgical fluid management system includes a console defining a cassette bay and a cassette, including a fluid line extending therethrough, configured for insertion into the cassette bay of the console. The console includes a sensor disposed adjacent the cassette bay configured to detect a position of the cassette relative to the cassette bay to enable selective locking or unlocking of the cassette within the cassette bay. Additionally or alternatively, the console includes cassette bay electronics configured to obtain encoded information from the cassette.

A washing device for the ear, nose and throat and the like (10) for domestic use or in medical offices which comprises a body (12) within which the components functional to the operation of the device are housed, a container element (14) defining a tank for a saline solution, a cannula (16) for use by the individual for the washing operations, a cable (18) for connecting to the power supply network.

A system and method include vibrating a needle of a phacoemulsification handpiece by driving one or more piezoelectric crystals in the handpiece with one or more electrical signals having different respective frequencies using one or more respective drive modules. The needle is inserted into an eye of a patient. The frequencies of the electrical signals are tuned to respective one or more target frequencies, and respective electrical impedances seen by the drive modules are registered. In response to an electrical impedance seen by at least one of the drive modules undergoing a change exceeding a preset impedance change, an indication is provided that material in the eye surrounding the needle has changed, a level of vibration of the needle is changed, and/or the frequency of at least one of the drive modules is adjusted to an electrical resonant frequency thereof.

A system includes an enclosure, an irrigation retainer, one or more sensors, and a processor. The irrigation retainer is coupled with the enclosure and configured to accept an irrigation container holding irrigation fluid for pumping to a phacoemulsification handpiece. The one or more sensors are coupled with the irrigation retainer and configured to provide at least one signal indicative of a remaining amount of the irrigation fluid. The processor is configured to receive the at least one signal, and in response to the at least one signal, output an estimation of the remaining amount of the irrigation fluid in the irrigation container or an estimation of the amount of irrigation fluid used.

An eye surgery system includes an Input/Output (I/O) device and a processor. The I/O device is configured to enable a user to define one or more eye surgery protocols, and further configured to, using the I/O device, present a graphical user interface (GUI) that displays one or more user defined eye surgery protocols. The processor is configured to (a) present the one or more user defined eye surgery protocols on the I/O device using the GUI, (b) test compatibility of the one or more user defined eye surgery protocols with the eye surgery system, and (c) provide an indication of the compatibility to a user of the eye surgery system.

An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.

Fluidic devices, methods, and systems are disclosed. One system may comprises a sheath, a delivery module, and a removal module. The sheath includes a working lumen, a delivery lumen, and a removal lumen. The delivery module is configured to move a fluid from a fluid reservoir and into a body cavity through the delivery lumen. The removal module is configured to move the fluid and a particulate contained therein out of the body cavity through the removal lumen, through a filtration device that removes the particulate, and back into the fluid reservoir. One method comprises placing a distal end of sheath into a body cavity, energizing the working lumen to generate a particulate in the cavity, moving the fluid into the cavity to engage the particulate, and moving the fluid and the contaminant from the body cavity, through a filter for removing the contaminant, and back into the fluid source.

An irrigation system includes a housing on which a trigger is movably mounted, a motor, an accumulator, a pump and a gearing arranged inside the housing. At least the motor and the accumulator are mounted in a drive unit which can be replaced.
