Patent ID: 11877770

Abstract:
A pulmonary access device comprises an elongated shaft having a proximal shaft section, a bendable shaft section, a distal shaft section, and a channel. The pulmonary access device further comprises a profiled stylet configured for being disposed in the working channel of the elongated shaft, the profiled stylet having a proximal stylet section with a first lateral stiffness profile, an intermediate stylet section having a second lateral stiffness profile less than the first lateral stiffness profile, a distal stylet section, wherein, when the profiled stylet is disposed in the working channel of the elongated shaft, the intermediate stylet section axially aligns with the bendable shaft section. The pulmonary access device further comprises a pull wire affixed to the distal shaft section, such that, when the pull wire is tensioned, the bendable shaft section bends, thereby deflecting the distal shaft section relative to the proximal shaft section.
