No
The description focuses on standard ultrasound imaging technology and signal processing, with no mention of AI or ML algorithms for image analysis, interpretation, or other functions.
No
The device is used for diagnostic imaging (ultrasound examination of coronary and peripheral intravascular pathology) and does not provide any therapeutic intervention.
Yes
The device is intended for "ultrasound examination of coronary and peripheral intravascular pathology" and displays "a high resolution, cross-sectional image... in real-time" of vascular tissues, which are all characteristics of a diagnostic device.
No
The device description clearly outlines multiple hardware components including a Console, Patient Interface Module (PIM), Linear Translation System (LTS), and Kodama Catheter, all of which are integral to the device's function. While software is mentioned as being housed in the console, the device is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is for "ultrasound examination of coronary and peripheral intravascular pathology" and "intravascular ultrasound imaging." This describes a procedure performed within the body (in vivo) to visualize structures.
- Device Description: The device collects "reflected ultrasonic (sound) waves from the Kodama catheter and render an intravascular image." This is the core function of an ultrasound system, which is an imaging modality used directly on or within the patient.
- IVD Definition: In Vitro Diagnostics (IVDs) are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, outside of the body (in vitro).
This device operates by emitting and receiving sound waves within the patient's blood vessels to create images, which is a direct imaging technique, not a test performed on a sample outside the body.

Device Description
The primary function of HDi System is to collect reflected ultrasonic (sound) waves from the Kodama catheter and render an intravascular image on the console touchscreen. The catheter emits sound energy from a transducer at the tip; sound waves reflected from the inner vascular tissues are received from the transducer and sent to the console where a high resolution, cross-sectional image is displayed on the touchscreen in real-time.
The main devices are the Console, Patient Interface Module (PIM), Linear Translation System (LTS) (optional), and Kodama Catheter.
The console houses hardware and software required to generate the energy used to excite the transducer in the Kodama catheter; it is the center of control and system architecture for how signals are acquired, processed, images constructed and presented, and overall power management and control of the PIM and LTS. The system digitally records case images, provides a review of recorded cases, and provides for the archival of recorded cases onto removable media.
The handheld PIM provides the electromechanical interface between the catheter and the console. It also provides the mechanical interface to secure the catheter, as well as the mechanical energy to rotate the catheter's imaging assembly. The LTS device provides automated, controlled linear translation of the catheter by providing mechanical coupling to the PIM and to the catheter's telescoping anchor as the PIM is pulled back along the longitudinal axis. The coupling between the LTS and PIM and LTS to catheter is strictly mechanical. The LTS device allows the user to perform automatic pullbacks and can be controlled via touchscreen buttons on the console or the buttons on the LTS. Manual pullbacks may be performed with or without the LTS, making the use of the LTS optional to the user.
The Kodama Catheter emits sound energy from its transducer at the distal tip, which is guided into the coronary and peripheral vasculature. The catheter can be operated at two different frequencies, 40MHz and/or 60MHz, depending on user preference. The catheter design includes an imaging assembly (with transducer, drive cable, coaxial cable, and rotor), sheath assembly (which includes the femoral marker and hydrophilic coating), telescope assembly, and catheter hub assembly. The electrical energy from the catheter is transmitted, via the transmission line embedded in the drive cable, back to the HDi console for signal processing and image reconstruction.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Kodama Catheter and HDi System was subjected to bench testing, including trackability and deliverability (including insertion/retraction force, cross/re-cross force, kink resistance, and torque strength), runtime, non-uniform rotational distortion (NURD) and buckling force. Where applicable, testing was leveraged from the predicate device to support this submission. Test results demonstrate that the Kodama Catheter and HDi System meet specifications and perform as intended. No new safety or performance issues were raised during the testing. The Kodama Catheter and HDi System are substantially equivalent to the predicate devices.
An animal study was conducted by ACIST Medical Systems in a laboratory environment, using a porcine model, to confirm the HDi System and Kodama Catheter imaging capabilities in the peripheral vessels and to collect supporting evidence regarding use of the HDi System and Kodama Catheter in the peripheral vessels. The physician also provided evaluation on the usability of Kodama catheter in peripheral arteries, such as catheter set-up, delivery and retraction. Test results demonstrate that the device meets specification and performs as intended. Results of the testing do not introduce or raise different questions regarding the safety or effectiveness of the device.
