EnSite™ Velocity™ Cardiac Mapping System v5.2:
The EnSite Velocity Cardiac Mapping System is a suggested Diagnostic tool in patients for whom electrophysiology studies are indicated.
When used with EnSite™ Array Catheter, the EnSite™ Velocity™ Cardiac Mapping System is intended to be used in the right atrium of patients with complex arrhythmias that may be difficult to identify using conventional mapping system alone.
or
When used with the EnSite™ Velocity™ Surface Electrode Kit, the EnSite™ Velocity™ Cardiac Mapping System is intended to display the position of conventional electrophysiology (EP) catheters in the heart
EnSite Precision Cardiac Mapping System v2.2:
The EnSite Precision™ System interfaces to either the MediGuide™ Technology System or the EnSite Precision™ Module to combine and display magnetic processed patient positioning and navigation mapping information.
When used with the EnSite™ Array™ Catheter, the EnSite Precision™ Cardiac Mapping System is intended to be used in the right atrium of patients with complex arrhythmias that may be difficult to identify using conventional mapping systems alone.
or
When used with an EnSite Precision™ Surface Electrode Kit, the EnSite Precision™ Cardiac Mapping System is intended to display the position of conventional electrophysiology (EP) catheters in the heart.
EnSite™ Verismo™ Segmentation Tool: The EnSite Verismo™ Segmentation Tool is indicated for use in generating 3D models from CT, MR or rotational angiography DICOM image data. Generated models are intended to be displayed on the EnSite Velocity System.
EnSite™ Derexi™ Module: When used with EnSite Derexi ™ Module, the EnSite System interfaces to the EP-WorkMate™ System / WorkMate Claris™ System for synchronizing and display of patient information.
EnSite™ Courier™ Module: When used with EnSite Courier Module allows the patient data to be archived to, and retrieved from, a DICOM conformant PACs server.
EnSite™ Fusion™ Registration Module: EnSite Fusion is indicated for registering the EnSite NavX navigation system to anatomic models, derived from CT scans, of the four individual cardiac chambers.
EnSite™ Contact Force Module: When used with the SJM Contact Force Unit, the EnSite™ Contact Force Module is intended to provide visualization of force information from compatible catheters.
EnSite™ AutoMap Module: When used with the EnSite AutoMap Module, the EnSite System is intended to automatically collect mapping points based on criteria set by the user.
EnSite™ AutoMark Module: When used with compatible hardware, the AutoMark Module is intended to automatically catalog and display various parameters associated with RF information on the 3D model in real-time.
