The EnSite® Catheter is a non-contact, single-use, multi-electrode array, transvenous catheter, designed for use with the EnSite clinical workstation. The EnSite® Catheter's multi-electrode array senses electrical activity generated from the endocardial wall while floating in the heart chamber. The array area of the EnSite® Catheter is comprised of an inflatable polyurethane balloon within a mechanically expandable multi-electrode array. The multi-electrode array contains a wire braid consisting of 64 braided wires. A handle and cable connector are located at the proximal end of the catheter to allow the physician to position the distal end of the catheter, deploy the multi-electrode array and make electrical connection from the array to the patient interface unit of the EnSite 3000® System's workstation.

The EnSite® Catheter is inserted transvenously over a standard guidewire into a selected chamber of the heart. When positioned, the wire braid is mechanically expanded and the balloon residing under the wire braid in the array area of the catheter is inflated with a radiopaque solution to form an ellipsoidal, multi-electrode array. When deployed, the array is small enough to permit the normal functioning of the heart. In addition to the EnSite® Catheter, a standard single-point diagnostic catheter is inserted in a chamber of the heart in order to facilitate establishing the chamber's spatial boundaries. The multi-electrode braid array collects data used to compute more than 3,000 points of the heart chamber's electrical activity in the span of a few heartbeats by gathering a large amount of the electrical conduction information from the entire chamber and transmitting this information through the wire braid back down the catheter shaft to the EnSite 3000® Electrophysiology Workstation.
