An endoscopic apparatus including a probe which is introduced into, for example, the intestinal tract of a living organism and which operates therein, adapted to perform one or more functions. In one embodiment, the probe communicates wirelessly with a portable electronic device outside the organism, the portable device which acts to relay data between the probe and a remote networked entity. In one variant, the probe includes an accelerometer to, for example, wake the probe up from a sleep mode when the organism is awake or ambulatory.

TIP PROPELLED DEVICE FOR MOTION THROUGH A PASSAGE
20180289930 · 2018-10-11 ·

A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, the end ones of which expand at least radially when inflated. Connecting passages provide fluid communication between each pair of adjacent chambers. A fluid source is attached to one of the end chambers. The connecting passages are such that the fluid inflates the chambers in a sequence, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The same sequence occurs when the chambers deflate, beginning with the chamber closest to the source, and ending with the chamber furthest from the source. The fluid source can either be a fluid supply tube, extending to a supply outside the lumen, or it can be built in and carried by the device. The device can crawl either along the lumen wall or on an inserted guide wire.

Method and system for generating mechanical waves

A system for generating a mechanical wave is disclosed. The system comprises a camshaft having plurality of rotatable cams, serially mounted on a shaft along an axis of an elastic tubular shell to form a varying phase angle along the shaft. The system further comprises a plurality of cam followers arranged circumferentially about each cam, such that a rotary motion of the cams generates a linear motion of the cam followers to radially bias in internal wall the shell. The variation of the phase angle is selected to generate a three-dimensional traveling wave along the shell.

Biological navigation device

Biological navigation devices and methods are disclosed. The devices can be used as or to support colonoscopies or endoscopes. The devices can have longitudinally extensible cells that can be selectively inflated. The devices can have articulable links. The devices can be removably attached to elongated elements, such as colonoscopes or other endoscopes.
