Description
RTMED Polyester Surgical Suture is an FDA-cleared, sterile, non-absorbable, synthetic braided multifilament suture composed of high-molecular-weight Polyethylene Terephthalate (PET). Precision-braided and uniformly coated with medical-grade silicone or PTFE to minimize tissue drag and capillarity, RTMED Polyester delivers indefinite tensile strength retention, superior knot stability, and exceptional fatigue resistance for cardiovascular, orthopedic, and general surgical procedures across Pakistan.

Clinical Benefits of Polyester in Surgery
- Indefinite Tensile Retention: Synthetic PET fibers will not degrade, providing lifelong structural holding for critical prosthetic implants and valve rings.
- Exceptional Knot Security: Braided multifilament construction eliminates knot slip while resisting dynamic repetitive mechanical loads.
- Atraumatic Smooth Coating: Medical-grade coating minimizes tissue friction, preventing the cheese-wiring effect common in uncoated braids.
- Biological Inertness: Causes minimal acute inflammatory reaction followed by complete fibroblastic encapsulation.

Surgical Handling & Knot Technique for Polyester Sutures
Due to its braided multifilament core and high tensile properties, RTMED Polyester suture offers exceptional handling characteristics and reliable tactile feedback during knot seating. Unlike monofilament alternatives that can suffer from spring-back memory, braided polyester adapts smoothly under the surgeon’s fingers and holds firmly under repetitive pulsatile cardiovascular stresses. This makes RTMED Polyester the suture of choice for prosthetic cardiac heart valve attachments, rotator cuff tendon anchorings, and heavy orthopedic soft tissue fixations in surgical centers across Pakistan.
Frequently Asked Questions on Polyester Suture Procurement
Q1: Are RTMED Polyester sutures US FDA approved?
Yes. RTMED non-absorbable Polyester braided sutures hold US FDA 510(k) clearance, CE marking, and ISO 13485:2016 certification, and are registered with the Drug Regulatory Authority of Pakistan (DRAP) under Class IIb medical device regulations.
Q2: Are RTMED Polyester sutures available with PTFE pledgets?
Yes. For cardiac surgery and valve reconstruction procedures, polyester sutures can be supplied in double-armed needle configurations pre-loaded with medical-grade PTFE felt pledgets to prevent suture pull-through in friable tissue.
Q3: How are these sutures packaged for hospital stock?
Supplied in boxes of 12 or 36 individually hermetically sealed, sterile foil packs with high barrier integrity to ensure sterility and prevent contamination.
