An ablation device including a body having a lumen for receiving a distal end of an endoscope, a cover portion extending from a side of the body, the cover portion defining a recess between the cover portion and the body, and an electrode platform having at least one electrode positioned thereon, the electrode platform movable between a covered position, where the at least one electrode is covered by the cover portion, and an exposed position, where the at least one electrode is at least partially exposed beyond the cover portion. At least one vacuum port is formed in the electrode platform.

In general, devices, systems, and methods for fiducial identification and tracking are provided.

A method of examining digestive tract images is provided. The method of examining digestive tract images include: obtaining a basic image taken by a photographing apparatus; obtaining a set H of pixels with Hue in the range of D1 in the basic image; obtaining a set S of pixels with Saturation in the range of D2 in the basic image; obtaining a set of pixels with Value in the range of D3 in the basic image, and recording it as an effective pixel range; selecting all pixel sets of the set H and the set S in the effective pixel range to form a detection graph block; examining whether the basic image is an unclean image according to the detection graph block. The present invention further provides a method of examining the cleanliness of the digestive tract, a computer device, a computer-readable storage medium thereof.

In general, devices, systems, and methods for control of one visualization with another are provided.

A surgical system includes an endotracheal system and intubation system. The intubation system includes an introducer rod and intubation instrument. The intubation instrument includes: an esophageal tube, intubation tube, endoscopic camera tube, and balloon located distally beyond a distal end of the intubation tube. The introducer rod is insertable through the intubation tube to a position where an endoscopic camera in the endoscopic camera tube has a line of sight to a distal end of the introducer rod. The balloon is movable from a deflated condition to an inflated condition in which the balloon fully occludes the esophageal opening to block advancement of the introducer rod into the esophagus and urge the introducer rod into the trachea. The intubation tube is removable from the patient leaving behind the introducer rod, such that the introducer rod is guides an endotracheal tube of the endotracheal system into the patient's trachea.

Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

Blockchain environments may mix-and-match different encryption, difficulty, and/or proof-of-work schemes when mining blockchain transactions. Each encryption, difficulty, and/or proof-of-work scheme may be separate, stand-alone programs, files, or third-party services. Blockchain miners may be agnostic to a particular coin's or network's encryption, difficulty, and/or proof-of-work schemes, thus allowing any blockchain miner to process or mine data in multiple blockchains. GPUs, ASICs, and other specialized processing hardware components may be deterred by forcing cache misses, cache latencies, and processor stalls. Hashing, difficulty, and/or proof-of-work schemes require less programming code, consume less storage space/usage in bytes, and execute faster. Blockchain mining schemes may further randomize byte or memory block access, further improve cryptographic security.
