Abstract: A medical instrument with an elongated outer housing and inner drive shaft and including an instrument flushing system that enables the medical instrument to be effectively cleaned after use is disclosed. The medical instrument may be configured such that the instrument flushing system receives a flushing fluid through a port at a proximal end of the instrument and directs the flushing fluid through a flushing fluid plenum created between an inner surface of the elongated outer housing and an outer surface of the inner drive shaft. The flushing fluid plenum may be maintained by a standoff formed from a collar with one or more axially extending grooves. The instrument flushing system may include a seal to seal portions of a drive system in communication with the inner drive shaft and extending radially outward from a main body of the medical instrument.

Abstract: A handle system usable for controlling medical devices, such as suture delivery devices. In at least one embodiment, the handle system may be directed to an embodiment configured to be used with a suture delivery device. The handle system may enable a suture delivery system of the suture delivery device to be partially actuated to prevent a needle from falling out of the suture delivery device. The needle and components of the handle system may be held in position through use of a position retention arm. By preventing the needle from falling out of the suture delivery device, the efficiency and safety of a medical device to which the handle system is attached is greatly increased. In addition, surgical personnel using a medical device incorporating the handle system are able to use the medical device in any position without risk of the needle falling out.
