Needle catheter with an angled distal tip lumen |
摘要 |
A needle catheter configured for injecting an agent into a wall of a patient's body cavity, which directs a needle from the distal tip of the catheter into the wall of the body cavity at an angle relative to the axis of the shaft. The resulting angled injection pathway improves the retention of the agent in the body cavity wall, while keeping a distal section of the catheter substantially perpendicular to the body cavity wall for optimal push against the tissue at the injection site.
