Abstract: A medical device system includes an insertion device and a medical device. The insertion device includes an insertion device handle, including a port on a handle body. The insertion device also includes an insertion device shaft extending from the insertion device handle. The insertion device shaft includes a working channel connected to the port. The medical device includes a medical device handle, including a movable handle portion and a stationary handle portion. The movable handle portion includes a bail portion movably positioned within a cavity in the stationary handle portion. The medical device also includes a medical device shaft. The medical device shaft is configured to be delivered through the port in the insertion device handle and through the working channel in the insertion device shaft. Movement of the movable handle portion relative to the stationary handle portion controls movement of a distal portion of the medical device shaft.

Abstract: Plasma delivery tips of medical-grade plasma generating devices are configured to exclude potential contaminants while operating within body cavities. In some embodiments, delivery tips are provided with an antechamber, which is optionally filled by pressure of ionizing gas to prevent contamination. Some embodiments are provided with one or more interior and/or exterior valves configured to prevent proximal ingress of contamination to the longitudinal position of the discharge electrode, or at all into the gas delivery lumen. In some embodiments, an expandable distal section of the plasma delivery tip acts as a valve which seals when closed, and when open expands to generate an inflated antechamber into which plasma is delivered.
