Advanced Transit Time Flow Measurement Technology for Vascular Surgery

Medistim developed the MiraQ Vascular as an advanced intraoperative Transit Time Flow Measurement (TTFM) platform designed to objectively assess vessel patency and blood flow during vascular surgery. The system is widely used in peripheral bypass procedures, AV fistula creation, carotid surgery, and complex vascular reconstruction cases to provide real-time intraoperative quality assurance.

Transit Time Flow Measurement technology uses ultrasound-based flow analysis to measure actual blood flow through vessels and grafts during surgery, providing immediate feedback to the surgeon. This enables the detection of technically inadequate anastomoses, stenosis, vessel torsion, or flow restrictions before completion of the procedure. The goal is to reduce early graft failure and improve long-term procedural success.

In vascular surgery, objective flow verification is especially important in distal bypass procedures where flow reserve may be limited. Traditional intraoperative assessment methods often rely on palpation or visual inspection alone, whereas TTFM provides quantifiable and reproducible flow measurements. This contributes significantly to the standardization of surgical quality control.

The MiraQ Vascular platform simultaneously evaluates several critical parameters including flow volume (mL/min), Pulsatility Index (PI), flow direction, and waveform morphology. Elevated PI values or irregular flow patterns can provide early warning signs of technical issues, helping surgeons determine whether immediate graft revision may be necessary.

The clinical value of TTFM has been increasingly supported by vascular surgery research over recent years. Studies have demonstrated that intraoperative flow verification can reduce early thrombosis rates and improve graft patency outcomes, particularly in distal peripheral bypass surgery and AV fistula procedures. Objective flow measurement is now recognized as an important contributor to long-term procedural success.

Medistim is widely recognized as one of the pioneering companies responsible for introducing and validating TTFM technology in clinical practice. Beyond device development, the company has contributed substantially to the academic standardization of intraoperative flow verification protocols. Today, Medistim systems are routinely used in many leading vascular surgery centers worldwide.

One of the major advantages of the MiraQ Vascular system is its ability to combine TTFM with high-resolution ultrasound imaging capabilities. This allows surgeons to perform both anatomical and functional assessments within a single integrated platform. In complex vascular anatomies, this hybrid approach provides significant clinical advantages.

The system supports a wide range of probe configurations suitable for various vessel sizes and anatomical regions. From small distal bypass vessels to larger peripheral vascular structures, the platform delivers reliable flow measurements across multiple procedural applications.

MiraQ Vascular also offers a highly intuitive workflow and user-friendly interface. Measurements can be performed within seconds, while flow curves and waveform analysis are displayed in real time. This rapid feedback structure improves patient safety while adding minimal additional procedural time.

Compared with alternative solutions, MiraQ Vascular stands out through its extensive clinical validation, strong scientific background in TTFM technology, integrated ultrasound functionality, and broad probe ecosystem. Its ability to provide both real-time functional flow verification and anatomical visualization represents a key differentiating advantage.

In summary, the Medistim MiraQ Vascular platform enhances intraoperative quality control in vascular surgery by delivering objective flow verification and supporting improved long-term bypass outcomes. As the clinical importance of Transit Time Flow Measurement continues to grow, MiraQ Vascular remains one of the leading reference solutions in modern vascular surgery.
