Corindus Inc.
Brief Summary

The objective of the present study is to detail the results of robotic-assisted PCI using technIQ automated movements in real-world clinical practice.

Detailed Description

This multi-center, international, randomized, open-label, post-market study will enroll subjects to detail the results of robotic-assisted PCI using technIQ automated movements in real-world clinical practice by randomized comparison with a cohort of subjects undergoing robotic-assisted PCI with technIQ automated movements disabled. A secondary objective is to describe the learning curve associated with using technIQ.

Primary Outcome Measures
NameTimeMethod
Major Clinical and Angiographic Complications (MCAC)72 hours post-procedure or until immediately prior to discharge from the index procedure hospitalization, whichever occurs first.

The rate of the combined MCAC endpoint (a composite of MACE and Major Clinical and Angiographic Complications) in the technIQ ON group is not significantly higher than in the technIQ OFF group.

Technical SuccessDuring the Procedure

Residual stenosis of \<30% in all target lesions with final TIMI (Thrombolysis In Myocardial Infarction) flow grade 3 by angiographic core lab analysis, AND absence of unplanned manual conversion.

Secondary Outcome Measures
NameTimeMethod
PCI procedure timeDuring the Procedure

Time between insertion of guide catheter and final removal of guide catheter.

Major angiographic complicationsDuring the Procedure

Reported as perforation(Type 1, 2, 3) or flow-limiting dissection (Type E, F).

Serious Adverse Events (SAE)Procedure through 72 hours postprocedure or hospital discharge (whichever occurs)

All Serious Adverse Events (SAEs) from the start of the CorPath GRX PCI procedure through 72 hours postprocedure or hospital discharge (whichever occurs) first will be summarized

Guidewire Wiring TimeDuring the Procedure

The time required to advance the guidewire from the tip of the guide catheter to the final target distal to the lesion.

Procedure success72 hours post-procedure or until immediately prior to discharge from the index procedure hospitalization, whichever occurs first.

The rate of procedure success in the technIQ ON group is not significantly lower than that in the technIQ OFF group.

Major adverse cardiovascular events (MACE),72 hours post-procedure or until immediately prior to discharge from the index procedure hospitalization, whichever occurs first.

Reported as a composite and components of Cardiac Death, Target Vessel MI, and Target Vessel Revascularization (TVR).

Total Procedural TimeDuring the Procedure

The time from the start of the sheath insertion to complete removal of the final guide catheter.

Total Fluoroscopy TimeDuring the Procedure

The total fluoroscopy time during the procedure as recorded by an Imaging System.

Subject Radiation ExposureDuring the Procedure

Dose-area-product (DAP) as recorded during the procedure

Planned Manual Conversion (PMC)During the Procedure

Planned manual conversion (PMC) is disengagement of the robotic drive to use bedside manipulation of either the guide catheter, guidewire, or delivery system that was prespecified in the procedural plan (e.g., to accommodate adjunctive devices or procedural techniques that are not compatible with the robotic platform, such as intravascular ultrasound or atherectomy devices). This will be assessed by a questionnaire.

Contrast Fluid VolumeDuring the Procedure

The total contrast volume used during the procedure.

Partial Manual Assistance (PMA)During the Procedure

Partial manual assistance (PMA) is the use of manual techniques that were not prespecified in the procedural plan and do not meet the definition of unplanned manual conversion (e.g., unplanned use of manual techniques to accommodate adjunctive devices or procedural techniques that are not compatible with the robotic platform). These will be assessed by a questionnaire.

Fluoroscopy Time to Cross LesionDuring the Procedure

The fluoroscopy time required to advance the guidewire from the tip of the guide catheter to the final target distal to the lesion.

Contrast Used to Cross LesionDuring the Procedure

The amount of contrast (in ml) required to advance the guidewire from the tip of the guide catheter to the final target distal to the lesion.

Subject Radiation DoseDuring the Procedure

air kerma (AK) as recorded during the procedure.

Unplanned Manual Conversion (UMC)During the Procedure

Unplanned manual conversion (UMC) is disengagement of the robotic drive to use bedside manipulation of either the guide catheter, guidewire, or delivery system that was not prespecified in the procedural plan, and that was due to inability to navigate to the target lesion as intended, cross the target lesion as intended, treat the target lesion as intended, retract the CorPath GRX system as intended, or other CorPath system device malfunction; or any clinical condition that requires rapid medical intervention. This will be assessed by a questionnaire.

Device MalfunctionDuring the Procedure

The device malfunction will report the inadequacy of the medical device with respect to its identity, quality, durability, reliability, usability, safety, or performance. Investigators are instructed to report all device deficiencies and device malfunctions using the device malfunction form in the EDC.
