The HF-OCT Imaging System

See how ultra-small catheter design and high-speed imaging work together to navigate tight lesions and visualize the entire vessel in one rapid pullback

HF-OCT Imaging Console

A mobile imaging platform engineered to support pre- and post-PCI assessment. Enables rapid, high-resolution visualization, automated measurements, and StentX stent analysis to guide treatment decisions, with intuitive image navigation and simple plug-and-play setup.

Console IFU cover stentX
Physician Monitor

The Physician Monitor offers an intuitive workflow designed to streamline procedural decision-making, with automated measurements and StentX-powered stent expansion visualization.

Operator Monitor

The Operator Monitor can be used via touch screen or mouse, with pinch, pan, and zoom functionality for easy navigation and image review.

Mobile Console

The console is designed for easy mobility, with a PIM cradle that protects the system’s optics, organized cord storage, and convenient transport features.

Probe Interface Module (PIM)

Mounted onto the bedrail, the PIM requires no sterile bags and allows plug-and-play setup with the Vis-Rx PRIME Micro-Imaging Catheter.

Detailed plaque visualization

High-resolution imaging that reveals detailed plaque morphology, including lipid-rich plaque, fibrous tissue, thrombus, and calcium, to guide lesion modification and/or intervention strategy.

AI decision support

Automated lumen measurements and StentX software for quantification and visualization¹ of stent expansion, one of the most important determinants of successful stent outcomes.²

AngioSync technology

Time-bound synchronization between HF-OCT and angiography images to ensure coordinated vessel visualization.

Streamlined setup

Supports quick system preparation without additional sterile bags.

Vis-RX prime
State-of-the-art Laser

State-of-the-art laser allows images to be captured quickly and accurately offering you insights in just one second

Redesigned Tip

Reduced tip stiffness to improve deliverability and reduce force when navigating complex anatomy⁴

Plug-and-Play Connection

Designed for simple plug-and-play connection to the PIM with no additional sterile bags required

Hydrophilic Coating

An extended hydrophilic coating to support smooth trackability and reliable delivery through challenging anatomy⁴

Vis-Rx® PRIME Micro-Imaging Catheter

Vis-Rx PRIME combines ultra-low profile, enhanced deliverability, and rapid imaging to support precise, guideline-aligned vessel assessment. Its small crossing profile allows navigation and clearing of tight lesions without pre-dilation4 and minimized contrast burden3, delivering detailed and comprehensive vessel visualization in just one second.

Ultra-low-profile

At 1.8F (0.6 mm), less than half the size of other intravascular imaging catheters4, Vis-Rx PRIME is capable of imaging vessels from 1.3 to 6.0 mm, including the left main.

Enhanced deliverability

Optimized design enabling smoother navigation through challenging anatomy and tortuous vessels.4

One-second imaging

Captures detailed vessel insights in just one second for rapid, actionable assessment.

Low contrast requirement or saline-compatible

Reduced contrast burden, as low as 5 mL per run3, or compatible with saline flushes.

“HF-OCT, because of its inherent characteristics — a small catheter profile, and very long and fast pullback — is an ideal platform for pre-stent imaging. In my early experience, even a severe 90% stenosis can easily be crossed prior to any kind of vessel instrumentation, and HF-OCT provides consistent, quality imaging. With this next-generation technology, we hope to enable even better treatment and optimization of PCI. It is a bright and exciting future.”

“There’s clear evidence supporting increased use of intravascular imaging. Gentuity's HF-OCT stands out with its low profile, speed, and long pullback, making it an excellent choice for daily practice and pre-intervention planning. The technology is impressive, the support team outstanding, and I’m excited to see adoption continue to grow.”

“The Gentuity OCT catheter enables near-whole-vessel imaging in about one second, with a low crossing profile that improves deliverability and expands imaging into smaller, more distal vessels.”

Specifications

Key technical specifications for the Vis-Rx PRIME Micro-Imaging Catheter

Working length & catheter design

165 cm rapid exchange catheter designed for imaging coronary vessels via femoral or radial access

Offset tip design

Offset distal tip design keeps the guidewire parallel to the imaging lens for added support during advancement

Distal tip marker

Distal marker located 4 mm from the tip provides a clear reference for tip position

Lens marker

Lens marker located 4 mm distal to the imaging lens to support lens positioning and AngioSync tracking

Proximal pullback marker

Proximal pullback marker located 100 mm from the lens provides a reference for imaging pullback distance

Simple catheter prep

Flush the hoop with heparinized saline to activate the hydrophilic coating, and purge the catheter side port to prepare the device for use
