Abstract: A system for performing a medical procedure comprises a robotic introducer assembly including: a base unit, the base unit including a proximal base portion and a base extension extending from the proximal base portion; and a probe assembly operably and removably coupled to the base unit. The probe assembly includes an articulating probe. The base unit is constructed and arranged to control a movement of the articulating probe. The system further comprises a sterile barrier system positioned over at least a portion of the robotic introducer assembly, the sterile barrier system providing isolation between any non-sterile portion of the robotic introducer assembly and the sterile field or any sterile operators (e.g. to prevent exposure of any non-sterile portion to the sterile field and/or sterile operators).

Abstract: A system for performing a medical procedure at a target location of a patient, including: an articulating probe including at least a distal portion; a feeder configured to advance, retract, and steer the articulating probe; a first introducer attached to the feeder and configured to slidingly receive the articulating probe; and a second introducer for providing access to an internal location of the patient. The first introducer operably attaches to the second introducer, such that the articulating probe can be advanced through the second introducer to the target location. The system further includes at least one sealing element configured to maintain insufflation pressure at the target location.

Abstract: A system for performing a medical procedure comprises a first assembly and a second assembly. The first assembly comprises an articulating probe assembly and a first housing. The articulating probe assembly comprises an outer probe and an inner probe. The outer probe comprises: multiple articulating outer links and a first connector. The inner probe comprises multiple articulating inner links and a second connector. The first housing comprises: a proximal portion; a distal portion; and an opening positioned in the first housing distal portion. The articulating probe is constructed and arranged to pass through the first housing opening.

Abstract: A cardioplegia delivery device for providing variable ratio delivery of blood and cardioplegia solution to a patient. The device includes separate pumps for crystalloid and blood. A heat exchanger control circuit is provided which includes a heater and an ice bath for warming or cooling the cardioplegia fluid delivered to the patient. The heat exchanger control circuit includes a priming circuit which may be used to purge air bubbles from the circuit.
