Polytetrafluoroethylene (PTFE): a new material for the construction of gastrointestinal cannulae.
The advantages of polytetrafluoroethylene cannulae are that they are resistant to chemical attack, light in weight, not brittle, inexpensive, adaptable, and they cause minimal tissue reaction. The design of cannulae for cannulation of gastric and duodenal fistulae, and drainage of pouches of the stomach is described. Similar cannulae offer many possibilities for use in other systems.
