Title: CANNULA CAPTURE MECHANISM
Abstract:
A cannula capture mechanism (12) may include an inner housing (18), outer housing (20), and a cannula (14). The outer housing may be configured to move between a compressed and a decompressed state. An outer surface of the inner housing may include one or more interlock components (46). When the cannula is exposed from a distal end of the inner housing, the one or more interlock components may interact with one or more interlock surfaces formed in another surface of the catheter device. When the cannula is retracted proximally within the inner housing, the inner housing may contract radially inward causing the one or more interlock components to be separated from the one or more interlock surfaces and the outer housing to move to the decompressed state and extend distally over a distal portion of the inner housing.
