EO sterilization and use for single use only.

It is indicated for use in adult and adolescent populations to endoscopically dilate strictures of the alimentary tract.

The 3-Stage Balloon Dilation Catheter can provide 3 different sizes and gradually increasing diameters through controlled radial expansion. The specific balloon size is printed on the label of each package and catheter. The 3-Stage Balloon Dilation Catheter is designed to pass through the working channel of the endoscope, and its guidewire cavity can accommodate a 0.035inches (0.89mm diameter) guidewire. In the package, a 0.035inches (0.89mm diameter) guidewire is pre-installed in the guidewire cavity. There is a guidewire locking device connected to the guide wire hole of the catheter. The locking device will be in the "OFF" (closed) position when it leaves the factory. Only when the switch of the locking device is in the "ON" position can it be pushed or moved forward. The guide wire is removed from the catheter. After turning the switch to the "OFF" position, the guide wire will be fixed in the catheter.

It is indicated for Endoscopic clip placement within the Gastromtestinal tract in adult patients only via a straight or side viewing flexible endoscope for the purpose of: (1) Endoscopic marking (2) Hemostasis for (a) Mucosal/ sub-mucosal defects < 3cm (b)Bleeding ulcers. (c)Polyps<1.5cm in diameter, (d)Diverticula in the colon (e)Arteries <2 mm (f) Prophylactic clipping to reduce the risk of delayed bleeding post lesion resection; (3) As a supplementary method, closure of GI tract luminal perforations <20mm that can be treated conservatively

The proposed device is a sterile, single-use endoscopic clipping device. It is consisted of two main components: the delivery system and the clip. The delivery system include: metal cap, spring sheath, pulling wire component, coating layer, protective tube, core rod, and slider. The clip include: clip components and sleeve, and it is deployed from the delivery system during use. The hemoclip can be opened and closed up to five times prior to deployment, aiding in repositioning of the clip at the lesion site. The device is available in four clip opening widths, which are 9mm, 11mm, and the device effective length is available in 1600mm, 1800mm, 2600mm, 2600mm.
