Boston Scientific Expect Pulmonary Endobronchial Ultrasound Transbronchial Aspiration Needle M00558220
The Expect Pulmonary Needle is a sterile, single-use 22-gauge cobalt‑chromium biopsy needle with a 1.6 mm sheath, compatible with Olympus EBUS bronchoscopes. It features an ergonomic rotating handle, sharp tip grind, and highly visible echogenic pattern for precise ultrasound-guided fine needle aspiration. It’s designed for sampling lesions in the tracheobronchial tree and GI tract via EBUS-TBNA.
Engineered with a cobalt‑chromium shaft, this needle delivers superior hardness, kink resistance, and consistent tip sharpness over multiple passes. The thin-wall 22 Ga design maximizes the internal lumen for optimal sample quality, comparable to larger-gauge alternatives. Its ergonomic handle has audible and tactile feedback for safe sheath retraction and controlled penetration. The echogenic shaft and tip allow clear ultrasound visualization of needle placement within lesions.
