Intraluminal Bowel Occluding Catheter
- Technology Benefits
- Prevents loss of endoluminal insufflationImproves safety of complex interventional intraluminal proceduresInternally occludes any gastrointestinal cavity to which it is able to conform
- Technology Application
- enhanced efficiency of transanal minimally invasive surgical procedures
- Detailed Technology Description
- Our inventors have designed a semi-rigid catheter with multiple channels that can be guided into position within the bowel either through an endoscope or working port. The distal end of the catheter has an attached flexible balloon capable of conforming to the size and shape of the bowel lumen when filled with either gas or liquid. The catheter may then be used to internally occlude any cavity to which it is able to conform, including the colon, small intestine, esophagus or stomach. Multiple independent channels on the proximal end of the catheter correspond to the individual internal channels within the catheter. These channels may be used for a variety of tasks including the insertion of a removable wire that can add rigidity to the catheter, gas injection, gas evacuation or internal lighting of the lumen.Stopcocks or valves at the end of each external channel may be used to open or occlude the individual channels.This invention is particularly ideal for performing endoscopic procedures in the rectum or the colon such as with colonoscopy. As well, it has proven especially useful for performing laparoendoscopic procedures within the rectum such as the transanal minimally invasive surgery (TAMIS) technique where loss of pneumorectum can be a significant impediment. The novelty of the intraluminal bowel occluding catheter offers an improvement in the safety and efficiency of many minimally invasive techniques while allowing for more controlled gas exchange to clear smoke or vapor.
