A newly designed puncture needle for suction decompression of giant aneurysms

✓ A newly designed puncture needle for aspirating large or giant aneurysms is described. This puncture needle represents a modification of an intravenous catheter with an internal needle. It is designed to prevent blood from leaking when the internal needle is removed and has a lateral tube for aspiration. Following aneurysm puncture with the parent artery temporarily trapped, the catheter is positioned on the head frame with a brain spatula and a self-retaining retractor. Blood is suctioned through the lateral tube with a syringe or the suction system normally used in the operating room.
