Patent number: 11154357Abstract: 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.Type: GrantFiled: June 21, 2018Date of Patent: October 26, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Steven W.

Patent number: 9801585Abstract: A catheterization system that includes an electrophysiologic (EP) catheter which has a lumen receiving an electrically conductive fluid delivered by a hydraulic line that is acted upon by a peristaltic pump advantageously avoids noise in intracardiac ECG signal recordings by using an electrical connection to short triboelectrical charge carried by the conductive fluid in the hydraulic line to an existing analog ground in the system. In one embodiment, the electrical connection includes an electrically conductive wire housed in the control handle and configured to provide electrical connection between the fluid and a pin on a printed circuit board housed in the control handle that is electrically connected to the analog ground. In another embodiment, the electrical connection shorts the electrically conductive fluid proximal of the control handle of the catheter.Type: GrantFiled: December 31, 2014Date of Patent: October 31, 2017Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Kruti Shah, Alexander Lifshitz, Itzhak Fang
