7 Hot, New GI Devices

Check out these game-changers from Digestive Disease Week's exhibit hall.

CHICAGO — Gastroenterologists in the market for a new device or game-changing technology were likely to find exactly what they were looking for — as well as a few cool surprises — on display in the exhibit hall at Digestive Disease Week. Here are 7 innovative advances I wouldn't mind having.

CapsoCam Plus

CapsoVision | CapsoCam Plus
Small-bowel diagnostics keeps improving thanks to advances in capsule endoscopy. With 4 on-board cameras and 16 LEDs, CapsoCam Plus provides twice the resolution of previous-generation CapsoCam capsules. The patient swallows the vitamin-sized capsule and goes home with only a retrieval system (no belts, harnesses or other wearable equipment), which includes a collection pan and magnetic wand used to recover the capsule. Upon collection, the patient returns the capsule to the doctor, who then downloads and analyzes the data. Capsule retrieval may be somewhat distasteful to some patients, and you have to consider the time required to sit down and analyze the data, but this could be a valuable first-line diagnostic tool for small-bowel diseases.


CDx Diagnostics | WATS3D
This WATS3D (Wide Area Transepithelial Sample with 3D Analysis) is more effective in the detection of Barrett's esophagus and dysplasia than forceps biopsy alone, says the company. It will increase your detection of precancerous abnormality of the esophagus when used as an adjunct to standard targeted forceps biopsy. The collection instrument is passed through the operating channel of a standard endoscope and adds minimal time to the overall procedure. A wide-sample brush biopsy designed to capture cells from a broader area, combined with a 3D imaging analysis (performed at a CDx Diagnostics lab), provides a comprehensive view of the cell structure to determine the presence of any abnormal cells. The turnaround for WATS3D is typically 5 to 7 days.

Linx Reflux Management System

Ethicon | Linx Reflux Management System
This anti-reflux device originally from Torax Medical (recently purchased by J&J's Ethicon) is a modern take on the Angelchik devices that have been around since the '70s for treating patients with chronic reflux, and this one is remarkably simple and durable. It's a small, flexible ring — about the size of a quarter — of titanium wire passing through a series of titanium beads, each with its own magnetized core. The device is laparoscopically implanted around the patient's lower esophageal sphincter; no alterations to the stomach are necessary. The ring expands to let food and liquid pass through the esophagus and into the stomach, and then magnetized beads come together to close the sphincter and keep acid and bile from coming up.

DiLumen Endolumenal Intervention Platform

Lumendi | DiLumen Endolumenal Intervention Platform
This disposable colonoscope accessory may be a valuable tool for difficult colonoscopy cases. The design includes a flexible sheath and 2 inflatable balloons — one ahead of the distal tip of the scope (fore); and another behind the bending section of the scope (aft) — connected by 2 push rods. When both balloons are inflated, the device stabilizes and isolates targeted bowel segments to create a "therapeutic zone," as Lumendi calls it, for quick and localized insufflation. The GI doc can use the twin push rods to fully extend the fore balloon to flatten the mucosal folds and expose hidden lesions for diagnosis and treatment. After the procedure, you deflate both balloons.
