Used to establish a conduit during endoscopic urological procedures, thereby facilitating the passage of endoscopes and other instruments into the urinary tract. The Flexor Parallel offers two options for placement: the traditional Flexor placement or the Rapid Release technique. The working channel protects the ureter during repeated instrument exchanges. The sheath also protects delicate instruments and smaller flexible scopes from damage. The sheath has a hydrophilic coating to create a low-friction surface as the ureter is dilated.
