An intubation device for use in an endotracheal intubation procedure includes: a laryngoscope blade having a tip and a base; a handle attached to the base of the blade; a channel, the channel including a blade channel portion extending along the blade substantially from the tip to the base and including an outlet proximate to the tip and a handle channel portion extending partially along the handle from the blade channel portion; and a tube movement mechanism in the handle, the tube movement mechanism including a thumb interface.

A colposcope includes an inserter including an elongated body defining an interior space and an image capture device configured to be selectively and slidably positioned within the interior space of the elongated body. The elongated body has a distal end portion and a proximal end portion. The distal end portion is substantially funnel shaped and has a distal end that includes first and second portions. The first portion includes a base at a first edge of the distal end, and the second portion includes a lip at a second edge of the distal end that is diametrically opposed from the first edge. The lip is positioned further from the proximal end portion than the base.

A computer-implemented method for estimating a size of a suspected polyp in an image includes accessing an image of in at least a portion of a gastrointestinal tract (GIT) captured by a capsule endoscopy device, wherein the image includes a suspected polyp; receiving an indication to an approximated periphery of the suspected polyp in the image; determining, without human intervention, a 3D measurement of the polyp based on peripheral points in the approximated periphery indication; and estimating a size of the suspected polyp based on the determined 3D measurement.
