CorPath™ 200: Robotically-Assisted Percutaneous Coronary Intervention (PCI)

Objective The study objective was to evaluate the safety and technical efficacy of the CorPath 200 System in delivery and manipulation of commercially available coronary guidewires and rapid exchange balloon/stent catheter for use in percutaneous coronary interventions (PCI).

I. Primary Endpoints A. Efficacy Device Clinical Success: Achievement of a < 30% final diameter stenosis after utilizing the CorPathTM 200 System to deliver a PTCA balloon and then stent to the target lesion, and successfully retract the devices without the occurrence of any In-Hospital MACE (Major Adverse Cardiac Event) evaluated at 48 hours post procedure or hospital discharge, whichever occurs first.

B. Safety In-Hospital MACE: Defined as the composite of death (all cause mortality), recurrent MI, and target vessel revascularization (emergent coronary artery bypass surgery [CABG] or PCI) evaluated at 48 hours post procedure or hospital discharge, whichever occurs first.

II. Secondary Endpoints A. Efficacy CorPath Success: Ability to navigate the guide wire and balloon/stent system utilizing the CorPath™ device to the target site without the occurrence of any In-Hospital MACE, evaluated at 48 hours post index procedure or hospital discharge, whichever occurs first.

Subject Clinical Success: Achievement of a <30% final diameter stenosis of target lesion after treatment with PTCA/coronary stent without the occurrence of any In-Hospital MACE, evaluated at 48 hours post-index procedure or hospital discharge, whichever occurs first.

B. Safety:

MACE at 30 Days: Defined as the composite of death, recurrent MI and/or target vessel revascularization (emergent coronary artery bypass surgery [CABG] or PCI) evaluated at 30 days post index procedure.

Adverse Events:

A summary of all adverse events observed in the trial summarized as either serious or non-serious and summarized by attribution.

C. Clinical Utility

Procedure Attributes:

• Reduction in radiation exposure to the primary operator based on radiation dosimetry measurements at the procedure table and on a primary operator.
• Total Procedure time based on the time of insertion of hemostasis sheath through the time of final guide catheter withdrawal.

CorPath Device Attributes:

Subjective assessment by the operator of the following device performance attributes:

• Movement of the guide wire (rotating and advancing) to the target.
• Maneuvering and position of the guide wire to the target.
• Movement of the stent/balloon (advancing) to the target.
• Ability to deliver the PTCA/stent system to the intended target lesion.
• Ease of use of the system by the interventional team.

Material & Methods Corindus obtained approval (from the CORBIC Ethics Committee and INVIMA - Colombian Ministry of Health) in 2009 to conduct the clinical study "CorPath™ 200 System: Coronary Remote Catheterization Feasibility Study" at CORBIC Cardio-Neuro-Vascular Institute, Envigado, Colombia.

The study is a single arm, open label, prospective registry to treat a de novo lesion (2.5 mm - 4.0 mm in diameter, 25.0 mm in length with >50% stenosis) utilizing the CorPath 200 System to deliver, manipulate and retrieve a guidewire and a balloon/stent catheter system.
