This invention relates to a method of catheter and radiating coil location in a human body. In particular, when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and its depth in the patient's body. A display is provided that shows both a reference image of a portion of a non-subject body and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device can be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient.

Devices and methods for body conduit lengthening and anastomosis creation can be used to treat patients with a variety of health conditions. For example, among other uses, this document describes esophageal lengthening and anastomosis devices that can be used to remedy esophageal atresia in neonatal patients.

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.

Devices, systems, and methods for guidewire placement for a jejunostomy tube are described herein. A system can include an elongated tube having a first end, a second end, and an engagement portion at the first end configured for engagement with an endoscope. An inflatable member can be coupled to the elongated tube and configured to transition from an uninflated configuration to an inflated configuration. A magnetic member can be coupled to the elongated tube and configured such that, in response to disposing an external magnetic assembly on a surface of the abdomen of the patient, the inflatable member can be urged against an inner surface of a jejunum wall of the patient such that any intervening structure between the surface of the abdomen of the patient and the inner surface of the jejunum wall is disposed between the external magnetic assembly and the inflatable member with substantially no fluid gaps.

A feeding tube with an inflatable balloon component, a kit containing the feeding tubing, and a method for intubating a patient to deliver the feeding tube to a desired location for delivering nutrients and/or medication to the patient are described herein.

A gastrojejunostomy tube is used when a patient's stomach must be bypassed, with nutrients and/or medication being delivered directly to the jejunum. In this situation, the stomach commonly fills with stomach acid and digestive enzymes, which may cause vomiting, acid reflux or other esophageal problems. The gastrojejunostomy drainage bag is provided to allow the contents of the stomach to be drained through the gastrojejunostomy tube, rather than building up within the patient's stomach. The gastrojejunostomy drainage bag includes a receptacle having a lower portion and an upper stem portion, the upper stem portion terminating in a port adapted for connection to the gastrojejunostomy tube. Preferably, a lower port is formed through the lower portion, allowing the contents of the gastrojejunostomy drainage bag to be selectively emptied. A method of releasing gas or trapped air from the stomach is also disclosed.

A feeding tube with an inflatable balloon component and at least one of (1) a carbon dioxide (CO.sub.2) sampling line, (2) a suction tube component, (3) a pH sensor, and (4) an electromagnetic sensor is disclosed. A kit containing the feeding tubing and at least one of (1) a carbon dioxide (CO.sub.2) sampling line, (2) a suction tube component, (3) a pH sensor, and (4) an electromagnetic sensor, and a method for intubating a patient to deliver the feeding tube to a desired location for delivering nutrients and/or medication to the patient are also disclosed.

An enteral nutritional supplement tube includes: a tube body; and a plurality of grasping sections. The tube body has a flexibility and is elongated. The grasping sections are disposed at a region of an outer peripheral surface of the tube body, the region being in a range from a distal end portion of the tube body to an intermediate region of the tube body in such a manner that the grasping sections are spaced apart from each other, the plurality of grasping sections being configured to be grasped.

This invention relates to a method of catheter and radiating coil location in a human body and in particular to the determination over time of the location of the tip of a catheter as it is inserted and during its use in the body. In particular when a radiating coil is used in conjunction with a catheter, a coil locating device can be used to determine the distance the coil is from the device and hence its depth in the body of a patient. To assist a clinician using the coil-locating device, a display is provided that shows both a reference image of a part or portion of a body (non-subject body) and an image of the coil located on the display with reference to the reference image. This is achieved by locating the coil-locating device on or over a predetermined landmark on the patient's body. The coil and its associated signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device has a preferable triangular shape in plan view that allows its uppermost apex to be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient. Preferable landmarks on a human body include the xiphoid sternal junction and the caudal/mid sagittal aspect of the jugular sternal notch.
