    摘要: An overtube for use with an endoscopic surgical instrument. In various embodiments, the overtube may comprise a substantially flexible helically wound continuous member forming a series of helical coils that define a hollow passage sized to receive a portion of the endoscopic surgical instrument therethrough. The coils may be configured to selectively interlock with each other to stiffen the overtube. An actuation system may be employed to steer the overtube and selectively stiffen it. Some embodiments include a second substantially flexible helically wound member that may be selectively wound between the first substantially flexible helically wound member or segments thereof.

    摘要: A first medical instrument includes a flexible catheter and a medical guidewire extendable beyond a distal end of the catheter. The catheter is adapted to slidably receive a rail-coupling portion of an adjunct medical device. The medical guidewire has first and second segments, wherein the bending moment of inertia of the first segment is less than the bending moment of inertia of the second segment. A second medical instrument includes a flexible catheter, a mechanized guidewire assembly, and a medical guidewire extendable beyond a distal end of the catheter. The catheter is adapted to slidably receive a rail-coupling portion of an adjunct medical device. The medical guidewire has an exterior surface including a repetitive series of spaced-apart surface elevation features. One example of surface elevation features is external threads. The spaced-apart surface elevation features are adapted for operable engagement with the mechanized guidewire drive assembly.
