Device Story

The ACIST HDi System and Kodama Intravascular Ultrasound Catheter provide real-time, high-resolution cross-sectional intravascular imaging. The system consists of a console, Patient Interface Module (PIM), optional Linear Translation System (LTS), and the Kodama catheter. The catheter, inserted into coronary or peripheral vasculature, emits sound energy at 40MHz or 60MHz via a distal transducer. Reflected ultrasonic waves are received by the transducer and transmitted to the console for signal processing and image reconstruction. The PIM provides electromechanical coupling for catheter rotation; the optional LTS enables automated, controlled linear pullbacks. The console renders images on a touchscreen for physician review. Used in clinical settings during interventional procedures, the device assists clinicians in visualizing vessel lumen, wall morphology, and implanted devices (e.g., stents), supporting clinical decision-making during interventions.

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 | | {4}------------------------------------------------ # Premarket Notification – Traditional 510(k) | | 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. | | Intended Use/Indications for Use | The ACIST HDi System is intended to be used for ultrasound examination of coronary and peripheral intravascular pathology. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal interventional procedures. | | | The ACIST Kodama Intravascular Ultrasound Catheter is intended for use with the ACIST HDi System. | | Comparison of Technological Characteristics to Predicate | The proposed devices are substantially equivalent to the predicate devices (K143701 & K173063) based on the same indications for use as described in the labeling, the same fundamental scientific technology, safety, and performance testing.
