Coronary Dilators — Pattern and Clinical Use
During coronary bypass grafting the target vessel may need gentle calibration or dilation before the graft is anastomosed. The dilator is a very fine, highly polished tapered probe passed into the arteriotomy to size the lumen and dilate it slightly. Sets carry graduated diameters, typically from about 1 mm upward in small increments.
Surface finish is critical because the probe passes directly against coronary intima — the tissue whose damage causes graft failure. Every dilator is polished and inspected, and tips are rounded so the probe cannot dissect the vessel wall.
Coronary Dilators Variants and Specifications
Standard coronary dilator sizing.
| Variant | Specification / use |
|---|---|
| 1.0–1.5 mm | Fine coronary calibration |
| 1.5–2.5 mm | General coronary dilation |
| 2.5–3.5 mm | Larger target vessels |
| Double-ended | Two sizes per instrument |
| Malleable shaft | Follows vessel angulation |
| Graduated set | Full sizing range |
Material, Finish and Quality Control
We forge Coronary dilators from 316L austenitic stainless. Every surface is polished and tips rounded, then inspected, because the probe passes directly against coronary intima. Each batch passes Rockwell hardness testing, dimensional checks on surface polish and tip radius, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Coronary Dilators From Surgical Star
Coronary dilators sell as graduated sets to cardiac surgical distributors and are standard in coronary bypass trays.
OEM, Certification and Ordering
Every Coronary dilators can be produced as a private-label line: your logo laser-marked on the shaft, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Our quality file is ISO 13485, our EU route is CE marking under MDR 2017/745, and our facility holds US FDA establishment registration. Conformity and ASTM F899 material certificates are issued against each order.
You order direct from the factory with no trading-house margin, on volume-tiered pricing and a minimum matched to your pattern and finish. Once your branded sample is signed off, expect roughly four to six weeks to bulk delivery, worldwide DDP. See how OEM & private label works →

Frequently Asked Questions
What are coronary dilators used for?
Gently calibrating and dilating a coronary artery before the graft anastomosis is constructed.
Why is surface finish so critical?
The probe passes directly against coronary intima. Intimal damage is a cause of graft failure, so polish and tip radius are inspected on every unit.
What sizes are needed?
A graduated set in small increments from around 1 mm, since coronary target vessels vary considerably in calibre.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
