CathLabVR
The virtual-reality CathLabVR System fills roughly the same space
as real cath lab equipment and includes:
Two monitors, one for displaying
fluoroscopic views, Virtual Assistant functions, navigation control,
and simulated patient information; the other for displaying physio,
cine, and still images, controls for the C-arm — as well as total
procedure running time, fluoroscopy and cine radiation time, and
contrast instilled
A manifold for contrast
instillation, balloons, balloon stents, guidewire, and catheter
A foot pedal used to capture cines and control fluoroscopy; a
joystick to maneuver the simulated C-arm; and a keyboard and mouse
to make onscreen selections
Multiple endovascular simulation modules cover a variety of
situations and procedures:
Realistic in Every Detail
The SmartCapture tool recognition enhances realism by
automatically recognizing and responding to instrument insertion and
removal. The simulator uses four carriages enabling the insertion and
rotation of up to four instruments simultaneously. In addition, the
CathLab VR simulator’s physics-based haptic engine provides
realistic changes in simulated physiology.
Integrated Haptics
Patented force feedback technology integrated with visual and
audio responses mimics the look and feel of an actual surgery. Users
actually feel the forces encountered when navigating interventional
catheters, wires, balloons, and stents within the virtual patient’s
anatomy. This helps to promote training in proper tool selection and
tool-handling techniques within the virtual anatomy.
Multiple Simulated Cases
The module includes training on placing balloons and stents in
stable and unstable patients. The simulation provides an ideal
environment for surgeons to practice and perfect minimally invasive
endovascular skills in an objective, repeatable, non-threatening
training environment.
The simulator also allows team training for the physician and
allied health personnel who will work together in the procedure.
Computer-generated Simulations
The CathLabVR System uses computer-generated models that closely
reproduce the anatomical variations and physiology of a wide range of
patients. A real-time display of fluoroscopic and cine images
provides realistic rendering with emulation of digital zoom allowing
evaluation of case-specific pathology and subsequent interventions.
The simulation provides an ideal environment for surgeons to practice
and perfect minimally invasive endovascular skills in an objective,
repeatable, non-threatening training environment.
Realistic Changes in Simulated Physiology
The comprehensive physics-based surgical simulator reacts
appropriately to the manipulation and deployment of actual diagnostic
and therapeutic devices, providing practice in accessing and
navigating through diverse anatomy. The appropriately responsive
physiology is reflected in changes in vital signs, hemodynamic wave
tracings, and patient responses, which enhance the decision-making
process. Depending on the underlying anatomy, these decisions will
impact the time to successfully complete the case, as well as in
determining whether not the problem lesions are effectively resolved.
A variety of cases with increasing difficulty call for the
management of complications, allowing users to assess and perfect
their skills. Measurable outcomes and metrics allow for objective
assessment of users.
Due to the different anatomical variations of the virtual
patients, users may need to select a different guide catheter,
guidewire, and/or lead to improve the success of navigating to the
desired location. For successful completion of the case, trainees
need to test leads prior to and after fixation to confirm
optimization of sensing and stimulation thresholds, and to withdraw
all delivery instruments and devices without damaging any of the
surrounding tissues.
