Ureteroscope devices and systems having a selectively extendable distal portion

Abstract

An example ureteroscope system (10) including a handpiece (110) and a catheter (104) is described. The handpiece has a distal end region (114), a proximal end region (112), an interior region (155), and a working channel port (118). The catheter extends from the distal end region of the handpiece. The catheter includes a working channel (152) in fluid communication with the working channel port, a proximal portion proximal to the handpiece, and a distal portion (140) distal to the handpiece and selectively extendable to an extended position and selectively retractable to a retracted position relative to the proximal portion. The distal portion includes a distal end defining a working channel opening in fluid communication with the working channel.
