MEDICAL PROBE WITH FLUID ROTARY JOINT
First Claim
1. A medical probe comprising:
- an external sheath;
a rotatable fluid conduit housed within said external sheath, said rotatable fluid conduit including an inner lumen; and
a fluid rotary joint comprising;
an outer housing including an external port, wherein said external sheath is connected to said outer housing;
a rotatable insert having an inner channel, wherein said rotatable insert is rotatable within said outer housing, and wherein a proximal portion of said rotatable fluid conduit is received within said inner channel of said rotatable insert, such that said inner channel is in fluid communication with said inner lumen;
wherein said inner channel is in fluid communication with said external port under rotation of said rotatable fluid conduit; and
wherein said rotatable insert is connectable to a rotational drive mechanism.

Abstract
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.
