ELONGATED MEMBER FOR MEDICAL USE AND CONNECTING MEMBER

摘要

An elongated member for medical use that is used to perform a procedure in a pulmonary airway. The elongated member demonstrates enhanced reachability within the pulmonary airway and is fabricated by connecting plural hollow members different from each other in lumen diameter, outer diameter and physical properties. This configuration advantageously eliminates the formation of a step or ridge that would impede the smooth movement or manipulation of a procedure instrument that is advanced or retreated within the lumen of the elongated member.

主权项

1. An elongated member for medical use for use in performing a procedure in a pulmonary airway, the elongated member comprising:
a first member disposed on a distal side of said elongated member; a second member in which a second lumen is formed; a connecting member having a distal insertion hole into which a proximal part of the first member is insertable, a proximal insertion hole into which a distal part of the second member is insertable, and a third lumen that communicates with the distal insertion hole and the proximal insertion hole.
