Document Type and Number:

Japanese Patent JP6389535

Kind Code:

B2

Abstract:

A coupler for coupling a flexible coaxial cable (32), a fluid cooling system (40) and the outer sheath (35) of a catheter (30), the coupler comprising: a fluid coupler body (845a) including: a fluid inlet (842a) configured to operably couple to a source of cooling fluid and receive fluid therefrom; a fluid outlet (843a) configured to operably couple to a fluid discharge; and an outer sheath coupler (845b) forming an aperture for coupling with an outer sheath (35) of a catheter while forming a fluid-tight seal therewith; and a fluid sealing system (819) housed in the fluid coupler body including: a distal sealing diaphragm (819a) configured to form a fluid-tight seal about an outer surface of an inflow lumen (842) and a fluid-tight seal with an interior surface of the fluid coupler body (845a) defining an outflow plenum (843b) in fluid communication with the fluid outlet (843a); and a proximal sealing diaphragm (819b) configured to form a fluid-tight seal about an outer surface of the coaxial cable (32) and a fluid-tight seal with an interior surface of the fluid coupler body(845a) thereby forming an inflow plenum (842b) in fluid communication with the fluid inlet (842a).
