Patent attributes
A medical instrument system comprises an imaging probe including a distal tip that includes a first sealing feature. The system includes an elongated medical instrument including a distal portion and a working channel extending to an opening in the distal portion to permit fluid to pass from the working channel. The distal portion includes a second sealing feature. A first interlocking feature is on an external surface of the imaging probe and a second interlocking feature is on an internal surface of the working channel. The imaging probe is configured to be selectively interlocked with the elongated medical instrument when the imaging probe is positioned within the working channel of the elongated medical instrument. The first and second sealing features are complementarily shaped and configured to contact one another to prevent passage of the fluid therebetween when the distal tip of the imaging probe has been advanced within the distal portion of the elongated medical instrument.
