To measure is to know the quality of surgery.
“TTFM is a reliable method to verify intraoperative graft patency.”

Vessel function or patency following an anastomosis is critical to successful surgery. Transonic’s intraoperative flow measurements will tell a surgeon if a vessel is indeed patent. With the unsurpassed accuracy of gold standard transit-time ultrasound technology, Transonic’s Surgical Flow meters and Flow probes provide immediate, quantitative data to objectively assess the quality of an anastomosis during coronary artery bypass grafting (CABG), vascular, transplant, cerebrovascular and microvascular surgeries.
Flow measurements augment the surgeon’s clinical impressions or signal a problem. Other advantages of this quantitative tool are:
- Measurements over a broad range of vessels from 0.5 mm to 40 mm
- Detection of unseen blood flow obstructions before leaving the OR
- Reduction of bring-backs
- Improved patient outcomes
-
-
Microvascular
Volume flow measurements in micro-vessels assess the quality of the reconstruction or replantation.
-
Cardiothoracic
Quantitative flow measurements verifies graft patency and detects flow obstructions for improved patient outcomes.
-
-
-
Cerebrovascular
Reduce intraoperative stroke risk by verifying flow and identifying inadvertent vessel compromise.
-
Transplant
Support transplant success by intraoperatively assess flow in both arteries and veins.
-
-
-
Peripheral Vascular
Real-time intraoperative flow measurements enhance surgical outcomes by confirming peripheral bypass patency.
-
Tissue Perfusion
Monitor microvascular perfusion on skin or organ surfaces.
