Catheter introducer system for exploration of body cavities |
摘要 |
A catheter introducer system for endoscopy includes a steering section and a propulsion section located near the end of the flexible, tubular catheter that is introduced in a body cavity. The propulsion section is designed to pull the rest of the catheter inside the body cavity, so there is no need to push the catheter along from outside the body. Propulsion may be accomplished by relatively movable gripping pads that selectively apply suction to the tissue. The steering section is designed to point the end of the catheter that is introduced into the body cavity in the desired direction. The catheter can thus be made very flexible in bending, and a larger diameter catheter can be used without discomfort to the patient. |
