Percutaneous puncture needle for large double-chamber venous trunks.

摘要

Needle for positioning in an intravascular position, after a single percutaneous puncture of large vein stems, two guiding elements for sensor or catheter implantation using the Seldinger technique. The needle consists of a conventional hub for receiving the end part of a standard syringe, a needle shaft characterized by having an inner lumen consisting of two juxtaposed passage chambers communicating with each other over their whole length, for simultaneously passing the two guiding elements, without any crossing over thereof, a needle level inclined in the largest axis in its first embodiment, in the narrowest access in its variant. The device is especially for percutaneous puncture of large vein stems during anesthetic-resuscitation procedures with a view to minimizing incidence of complications.
