Beschreibung
Zusammenfassung:	A catheter is provided that includes an external sheath, a rotatable conduit housed within the external sheath, and a fluid rotary joint having a rotatable insert that places an inner lumen of the rotatable conduit in fluid communication with an external port under rotation of the rotatable conduit. The rotatable insert may include a channel structure including an external annular channel. The rotatable conduit is received within the channel structure such that the inner lumen is in fluid communication with the external port through the annular channel under rotation. The external sheath may define an outer lumen that may be in fluid communication with the inner lumen at a location remote from a proximal portion of the catheter, and the outer lumen may be in fluid communication with a secondary port. The rotatable conduit may be housed within a torque cable that is connected to the rotatable insert.
