Abstract
An apparatus includes a body, a catheter, and a fluid connector assembly. The catheter extends distally from the body and includes at least one electrode and at least one irrigation port. A fluid conduit is in fluid communication with the at least one irrigation port. A fluid connector assembly extends proximally from the body and includes a fluid connector body and a grounding member. The fluid connector body is configured to couple with a complementary connector associated with a fluid source. A proximal end of the fluid conduit is positioned in an interior region of the fluid connector body. The grounding member is interposed between the proximal end of the fluid conduit and the fluid connector body. The grounding member is in communication with the interior region of the fluid connector body such that the grounding member provides an electrical ground to fluid communicated to the fluid conduit via the fluid connector body.
