Problems solved by technology

Although simple to handle, such tubes are considered less durable and more likely to cause tube complications such as accidental gearing (see, for example, Funaki et al. 2001, AJR, 177(2); 359-362), which is developing in mature Before the fistula tract, it can be very dangerous within 14 days after insertion (see, for example, Marshall et al. 1994, JClinGastroenterol, 18(3):210-2)

Embodiment Construction

[0093]In particular, the present invention relates to gastrostomy tube systems comprising a gastrostomy tube with an improved retention structure. Compared to the retaining structures described so far, the improved retaining structure can be separated and disassembled from the tube under external manipulation to facilitate easy and safe removal of the tube. Advantageously, the tubes and retention structures disclosed herein can be detached and removed without endoscopy and with minimal patient discomfort. In certain embodiments, gastrostomy tubing systems provided herein facilitate multiple tube replacements with a single retention element that can be retained in the stomach while the tube is being replaced. When the tube system is no longer needed, the retention structure can be released from the tube (eg, into the stomach) and the tube can simply be withdrawn.

[0094] Although commonly referred to as percutaneous endoscopic gastrostomy, the device can also be used for surg...

Abstract

Ostomy tubes, particularly gastrostomy tubes, with improved retention means are provided. More specifically, retention structures, such as bolsters, for gastrostomy tubes are provided, configured to removably assemble to one end of a gastrostomy tube to facilitate replacement and removal of the tube. The retention structures provided herein may comprise one or more removably assembled retention elements. Further provided are gastrostomy tubes comprising such retention structures, and methods for percutaneous endoscopic gastrostomy utilizing same.

Description

technical field [0001] The present invention relates to devices and methods for percutaneous endoscopic gastrostomy (PEG) and other surgical procedures requiring the creation of a stoma in a body cavity. More precisely, the present invention relates to ostomy tubes, such as PEG tubes, with improved retention means. Background technique [0002] Percutaneous endoscopic gastrostomy (PEG) is an endoscope-assisted medical procedure used to place a feeding tube through the abdominal wall and into the patient's stomach. Placement of PEG tubes in large cohorts of the same age and same disease state allows for the placement of nutrients, fluids and / or medications directly into the stomach when oral intake is insufficient or impossible. [0003] There are several techniques for performing PEG. Generally, the procedure involves placing an endoscope in the patient's mouth and advancing the endoscope down the esophagus and into the stomach. An endoscope allows visualization of the ga...
