The Medtronic Ti-Cron braided polyester suture is available from MedicalEx in the configurations listed below. A uniform silicone coating gives the polyethylene terephthalate braid its lubricity, and the line is a long-standing choice where permanent support and prosthetic implant security matter.
Braided polyester with a uniform silicone coating
Permanent tensile strength for long-term support
Dyed blue with D&C Blue No. 6 or undyed white
PTFE pledget configurations act as suture buttresses
Ti-Cron sutures are nonabsorbable sterile strands braided from polyethylene terephthalate polyester fiber. A uniform silicone coating increases surface lubricity, which improves handling, eases passage through tissue and helps knots run down smoothly. The braided construction delivers high tensile strength in both linear and knotted form, giving maximum security when tissues are approximated under stress. Tensile support is permanent, so the line is used where indefinite approximation is required, including fixation work around prosthetic implants. Medtronic indicates the line for general soft tissue approximation and ligation, including cardiovascular, ophthalmic and neural tissue, in USP sizes 7-0 through 5.
Features and Benefits
Silicone lubricity – The uniform coating lets the braid glide through tissue and seat knots with less drag than uncoated polyester.
Permanent strength – Polyester retains its tensile strength indefinitely, supporting repairs that cannot rely on absorbable timelines.
Prosthetic security – High knotted strength makes the line a standard choice for securing prosthetic material and devices.
Pledget configurations – PTFE pledgets are available on selected codes to buttress tissue and spread load at the stitch.
Broad needle range – Configurations cover fine 7-0 work through size 5, across taper, cutting and spatula needle families.

Why Choose This Product
Where a repair must hold for the life of the patient, braided polyester is the traditional answer, and the silicone coating is what sets this line apart in handling. Cardiovascular and implant teams value the combination of permanent strength, smooth knot run-down and pledgeted options in a single family.
Coating advantage – The uniform silicone layer is the differentiator against uncoated polyester braids, improving passage and knot behavior in dense tissue.
Stress rated closures – High linear and knotted tensile strength supports approximation of tissues under stress conditions.
Implant workhorse – Permanent support plus pledget options makes the line a default for prosthetic fixation sets.
Frequently Asked Questions
Why choose a coated polyester over plain polyester?
The silicone coating increases surface lubricity, so the strand passes through tissue more easily and knots run down with better control. The underlying polyester braid keeps the permanent tensile strength polyester is known for.
Can this line be used with prosthetic implants?
Yes. Medtronic positions the line for maximum security with prosthetic implants, and selected configurations include PTFE pledgets that buttress tissue at the fixation point.
How should sutures be stored?
Store sutures in their original packaging in a cool, dry place away from direct heat and light. Use stock in expiry order and do not use any suture whose package is opened or damaged, since sterility cannot be assured.
What do the suture size numbers mean?
USP suture sizes run from fine to heavy: more zeros mean a finer strand, so 7-0 is finer than 5-0, which is finer than 3-0. Sizes then rise through 0, 1, 2 and heavier for large tissue work. The variant label states the exact size of each configuration.
Can a suture be resterilized or reused?
No. These are sterile single use devices, and an opened or expired suture must be discarded. Resterilization is not permitted and compromises both sterility and material performance.
