01

100% high-density PTFE

Manufactured from a single strand of high-density polytetrafluoroethylene, undyed and with no additives, giving a biologically inert and chemically non-reactive suture material.

02

Non-absorbable monofilament

As a non-absorbable monofilament, TEFLENE is not subject to weakening by tissue enzymes and continues to support the wound throughout the healing period.

03

Low-friction, smooth passage

PTFE's very low friction coefficient lets the strand slide easily through tissue, with an ultra-smooth surface intended to limit the potential for tissue damage.

04

Secure, flattened knots

The soft, flexible strand ties down to a snug, flattened knot; forcing air from the suture as tension is applied supports dependable knot security.

05

No package memory

TEFLENE presents no package memory, offering a soft, flexible strand that is easier to handle than many stiffer monofilament sutures during placement.

06

Multiple sizes and needles

Available in U.S.P. sizes 6-0 through 2-0, non-needled or attached to standard stainless steel needles, with black-needle SKUs for enhanced intra-operative visibility.

What TEFLENE PTFE Suture Is

TEFLENE is a non-absorbable, monofilament surgical suture manufactured from 100% high-density polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. Dolphin Sutures is the first Indian brand to introduce PTFE sutures, and the product is CE certified with DNV GL Presafe, Norway. The material is biologically inert, chemically non-reactive and very strong, making it suited to procedures where lasting soft-tissue support is required.

Composition and Construction

The suture is extruded from 100% high-density PTFE polymer to produce a structure with minimal pore size and volume while maintaining integrity and tensile strength. It is undyed with no additives. Being a single-strand monofilament, it does not present the interstices of braided constructions. Where a needle is supplied, it is a standard stainless steel surgical needle; sutures are also available non-needled.

Handling Characteristics

PTFE has a very low friction coefficient, allowing the strand to slide easily through tissue and limiting the potential for tissue drag. TEFLENE shows no package memory and offers an ultra-smooth surface with high tensile strength. Because it is a monofilament, adequate knot security benefits from flat, square ties with additional throws, tensioned by pulling each strand evenly rather than by pulling the needle. As a non-absorbable material, it is not weakened by tissue enzymes and provides continuing wound support.

Presentations

TEFLENE is available in U.S.P. sizes 6-0, 5-0, 4-0, 3-0 and 2-0, in a range of suture and needle lengths. Selected SKUs are offered with black needles to enhance visibility during surgery. Needle profiles include 3/8 circle reverse cutting in lengths such as 16 mm, 19 mm and 25 mm, with 50 cm suture lengths across the catalogue.

What is TEFLENE PTFE Suture made of?
TEFLENE is manufactured from 100% high-density polytetrafluoroethylene (PTFE), a synthetic fluoropolymer of tetrafluoroethylene. It is a single-strand monofilament, undyed and with no additives. Where a needle is supplied, it is a standard stainless steel surgical needle. The material is biologically inert and chemically non-reactive.
What is TEFLENE intended to be used for?
PTFE suture is intended for soft tissue approximation and/or ligation in appropriate surgical procedures, including cardiovascular, dental and general surgeries, as well as repair of the dura mater. It is not indicated for ophthalmic surgery or peripheral neural tissue.
Is TEFLENE absorbable?
No. TEFLENE is a non-absorbable suture. It is not absorbed and is not subject to weakening by tissue enzymes, so it continues to provide support to the tissues during the healing process. Skin sutures are normally removed within about 30 days, at the physician's discretion depending on wound condition.
What sizes and needle options are available?
TEFLENE is available in U.S.P. sizes 6-0, 5-0, 4-0, 3-0 and 2-0, either non-needled or attached to standard stainless steel needles. Needle profiles include 3/8 circle reverse cutting in lengths such as 16 mm, 19 mm and 25 mm. Selected SKUs feature black needles for enhanced visibility.
Is TEFLENE supplied sterile?
Yes. TEFLENE PTFE sutures are sterilized by ethylene oxide and supplied in sealed sterile packaging for single use. Do not re-sterilize, and do not use if the package has been opened or damaged. Any opened, unused sutures should be discarded.
How should TEFLENE be stored?
Recommended storage is 10°C to 35°C, away from moisture and direct heat. Do not use the product after its expiry date. Keeping the packaging intact within these conditions helps preserve the sterility and performance of the suture until use.
Are there contraindications for TEFLENE?
Use of this suture is contraindicated in patients with known sensitivities or allergies to polytetrafluoroethylene. The safety and effectiveness of the suture in ophthalmic, microsurgical and peripheral neural applications has not been established. Surgeons should be familiar with techniques involving non-absorbable sutures.
How can distributors obtain documentation and place orders?
TEFLENE is manufactured by Dolphin Sutures and is CE certified with DNV GL Presafe, Norway. Distributors and procurement teams can request the Instructions for Use, product specifications, certificates and the full SKU catalogue with codes, needle profiles and lengths directly from Dolphin Sutures to support registration and ordering.
