The Radial Access Alternative

CSI is leading the way in providing innovative solutions that enable a streamlined approach for your patients from treatment to discharge by providing you with the only extended length atherectomy system designed to treat peripheral artery disease (PAD) through radial access.

Proven Technology

REACH PVI is a prospective, observational, single-arm study designed to evaluate acute clinical outcomes of orbital atherectomy (OA) via transradial access for treatment of PAD in lower extremity lesions. A total of 50 patients were enrolled across six US centers.

It is the first multi-center study to evaluate outcomes of OA utilizing transradial artery access.

Utilizing orbital atherectomy in radial peripheral vascular interventions (PVIs) was shown to have a high rate of procedural and treatment success, delivering confidence with our proven orbital atherectomy technology, while providing you an alternative access site option to treat your patients.

Study Takeaways1

High Rate Of Success

Low Complication Rates

*Final residual stenosis <50% without stent placement or <30% residual stenosis with stent placement and without significant angiographic complications.
**Successful completion of OA treatment of target lesion via transradial access without serious transradial access related events.

Effective in Reducing Residual Stenosis Across All Lesions


Short Recovery Time for Improved Patient Satisfaction and Staff Efficiency



Optimize the Patient Experience


CSI’s peripheral orbital atherectomy system is the only atherectomy device that enables you to use radial access in peripheral interventions giving you another option when facing dynamic procedural challenges by providing an alternative access site for challenging anatomies, enabling immediate ambulation post-procedure2, and faster discharge times which can improve the patient experience. These benefits help to address the daily challenges you and your team experience while providing increased patient satisfaction.3

  • Decreases time to hemostasis4
  • Provides immediate ambulation post-procedure2
  • Shortens (hospital) stay5
  • Minimizes access site bleeding complications2
  • Avoids diseased common femoral arteries6
  • Allows treatment of bilateral disease in one procedure6
  • Eliminates need for femoral closure devices2
  • Improves patient experience2, 3
