Provided is a tissue retrieval bag. The bag is defined by a region of the bag defining an opening; an exterior surface of the bag depending from the opening; and a channel formed into the exterior surface of the bag, wherein the channel provides access to the interior of the bag through the exterior surface. Also provided is a tissue retrieval defined by a region of the bag defining an opening; an exterior surface of the bag depending from the opening; and at least one porthole on the exterior of the bag, wherein at least one tube extends from the at least one porthole.

A sleeved gastrojejunostomy (GJ) tube, according to the present invention, includes an inner cannula or feeding cannula that is housed in a sleeve. This arrangement allows the inner cannula to be replaced easily at the bedside by non-specialists. Traditional methods to insert the sleeved GJ tube are utilized, but in the event of feeding cannula damage or clogs, the inner cannula can be easily removed and a new one can be placed, without the need for fluoroscopy or anesthesia. The use of sleeved GJ tubes will expedite patient care, reduce complications, and decrease healthcare costs. The present invention aims to solve the common issue of a clogged GJ Tube. Clogged GJ tubes lead to emergency room visits, hospital admission, and interventional procedures. The present invention would enable exchanges of a clogged feeding cannula by providers or parents without radiation, sedation, or room time.

The present invention provides a sheath for gastrostoma (1), a sheathed dilator, a gastrostomy catheter kit and a method of splitting a sheath for gastrostoma. The sheath for gastrostoma (1) includes a sheath body (11) in which a gastrostomy catheter (2) is inserted and a handle (12). The sheath for gastrostoma (1) lowers the insertion resistance of a gastrostomy catheter when inserted in a fistula before insertion of the gastrostomy catheter in the fistula for replacement in the patient's body. According to the invention, a sheath for gastrostoma, a sheathed dilator, a sheath for gastrostoma with insertion aid, a gastrostomy catheter kit and a method of splitting a sheath for gastrostoma which can lower the insertion resistance during placement of a catheter in the patient's body, facilitate air supply control of an endoscope and stabilize endoscopic visual field during surgery are provided.

A nasogastric tube includes an outer tube and an inner tube. The outer tube has a receiving space and at least one opening, the receiving space is formed within the outer tube, and the opening is connected to the receiving space and formed at a sidewall of an end of the outer tube. The inner tube is longitudinally mounted in the receiving space to pass through the end of the outer tube and has an accommodating space and at least one through hole. The accommodating space is formed within the inner tube, and the through hole is connected to the accommodating space and formed at a sidewall of the inner tube passing through the end of the outer tube.

The present disclosure discloses a nasogastric tube used to insert into a patient's body from nose to stomach. The patient's body from nose to stomach comprises a posterior pharyngeal wall, an inferior conch, a nasopharynx rear-upper wall, and a soft palate; the nasogastric tube comprises a tube body and a pressurized structure. The tube body has a longitudinal direction and includes a proximal end and a distal end. A distance is between and the posterior pharyngeal wall. The pressurized structure is disposed on the tube body along the longitudinal direction and near the distal end. The pressurized structure comprises a cavity. When a fluid is filled into the cavity, the pressurized structure is pressurized; and the distal end is lifted to reduce the distance to the posterior pharyngeal wall.

Provided is a tissue retrieval bag. The bag is defined by a region of the bag defining an opening; an exterior surface of the bag depending from the opening; and a channel formed into the exterior surface of the bag, wherein the channel provides access to the interior of the bag through the exterior surface. Also provided is a tissue retrieval defined by a region of the bag defining an opening; an exterior surface of the bag depending from the opening; and at least one porthole on the exterior of the bag, wherein at least one tube extends from the at least one porthole.

A device includes a flexible catheter and a material. The catheter includes at least a first channel extending therethrough and is sized and shaped to extend from a proximal end outside a human body to a distal end that can be guided to a target location within a gastrointestinal (GI) system. A first distal portion of the catheter includes at least one exit port communicating with the first channel for administering a fluid to a patient anatomy. The material is fixed to an exterior of the catheter or ejectable from an interior of the catheter into the location that, in a first state or shape, is suitable for guiding the catheter to the location and, in a second state or shape, is suitable for engaging an inner wall of the location to anchor the catheter in the location while administering the fluid via the first channel.

An imaging apparatus includes: a tube; a light-emitting part in the tube; a driver that switches emission and non-emission of light from the light emitting part; a camera that takes images of the target object; a controller that controls the driver and generates a display image using the image obtained from the camera; and a display that displays the display image; where the controller generates a light position image corresponding to the light from the light-emitting part based on the difference between a first image obtained from the camera correlated with the light emission and a second image obtained from the camera correlated with the light non-emission, and generates the display image by overlaying the light position image in a visible color on an exterior image of the target object obtained from the camera.
