crossing profile
The compressed diameter of a device during delivery through a vessel or lesion.
Full Definition
Crossing profile refers to the outer diameter of a medical device when compressed or constrained within its delivery system, representing the minimum vessel lumen required for device passage during endovascular procedures. This measurement is critical for device selection as it determines whether a particular stent, balloon, or other device can successfully navigate through stenotic lesions, tortuous anatomy, or small-caliber vessels. Crossing profiles are typically measured in French units or millimeters and include the device, delivery catheter, and any protective sheaths. Lower crossing profiles enable treatment of more complex lesions and reduce vessel trauma during device delivery. Modern device designs focus on minimizing crossing profiles while maintaining device performance, with innovations including thinner strut designs, improved delivery systems, and advanced materials that allow for greater compressibility.
In Context
- "The stent's low crossing profile of 0.017 inches enabled successful delivery through the tight stenosis." — Coronary intervention report
- "Device selection was limited by the vessel's small caliber, requiring a balloon with minimal crossing profile." — Peripheral intervention planning
