What is the intended use of the Mitsu FST™ absorbable suture?

Mitsu FST™ is a short-term absorbable surgical suture used for soft tissue approximation and closure where brief wound support is needed. It is intended for closure of superficial tissues such as skin and mucosa during appropriate surgical procedures.

How is the Mitsu FST™ suture placed during soft tissue closure?

During a procedure, the surgeon passes the attached needle and Mitsu FST™ suture thread through soft tissue edges to bring them together. The braided suture is secured with surgical knots that hold tissue approximation until early healing begins

What materials and structure define Mitsu FST™ sutures?

Mitsu FST™ is made of a copolymer of low-molecular-weight glycolide and lactide (Polyglactin 910) and is braided and coated to improve handling. The structure gives initial strength and predictable degradation as the suture is absorbed by hydrolysis over time.

How does Mitsu FST™ perform after placement in tissue?

Once placed, Mitsu FST™ sutures provide short-term tensile support and then gradually lose strength as they degrade by hydrolysis. The material is designed for rapid tensile strength reduction, with predictable absorption suitable for superficial soft tissue support.

What follow-up observations are typical after using a Mitsu FST™ suture?

After soft tissue closure, clinicians check the wound edges for secure approximation and examine suture performance through follow-up visits. They monitor that tissue edges remain coapted and confirm that the absorbing suture is not causing undue local irritation.

Polyglactin 910 Suture – Fast Absorbing

Home > Endo-Surgery > Mitsu FST™

MITSU FST™ is a short-term absorbable, braided, coated synthetic suture made from low molecular weight Polyglactin 910. It consists of a copolymer of 90% glycolide and 10% L-lactide and is available in an undyed form. MITSU FST™ is designed to provide short-term wound support with rapid and predictable absorption. The suture gradually loses tensile strength and undergoes degradation through hydrolysis.

Key Features

Excellent Knot Security : Designed to provide excellent knot security when used with appropriate surgical technique.

Undyed : Available in an undyed form for applications where an undyed absorbable suture is appropriate.

Rapid Absorption : Designed for applications requiring short-term wound support, with complete mass absorption by approximately 42 days.

Predictable Tensile Strength Retention : MITSU FST™ retains approximately 50% of its knot tensile strength for up to 5 days, supporting wound approximation during the initial healing period.

Excellent Handling Properties : The braided construction provides excellent handling characteristics during superficial soft-tissue approximation.

Predictable Absorption

MITSU FST™ gradually loses tensile strength following implantation and undergoes absorption through a hydrolytic process.
Approximately 50% of the original knot tensile strength is retained for up to 5 days, followed by continued degradation and absorption. Complete mass absorption occurs by approximately 42 days. This rapid absorption profile is intended for applications where short-term wound support is required.

Instructions for Use

For detailed information regarding indications, contraindications, warnings, precautions, handling, storage, and instructions for use, please refer to the MITSU FST™ Instructions for Use (IFU).

Indication

MITSU FST™ is indicated for superficial soft-tissue approximation of the skin and mucosa where only short-term wound support of approximately 7–10 days is required. Its rapid absorption profile is particularly useful for applications such as skin closure, including episiotomy repair, and closure of oral mucosa. Suture selection should be based on the patient condition, tissue characteristics, wound size, surgical technique, and surgeon's clinical judgment.
