Ethicon | Prolene Polypropylene Suture | Non-Absorbable Synthetic Monofilament | Model M8743 | Double-Armed Micro Taper Point BV175-6

The Ethicon M8743 is an ultra-fine, sterile, synthetic non-absorbable surgical suture manufactured from an isotactic crystalline stereoisomer of polypropylene. Engineered as a perfectly smooth monofilament strand, Prolene virtually eliminates cellular tissue drag and dynamic friction during placement. Polypropylene is designed for setups requiring permanent wound support, remaining completely unaffected by active in vivo enzymatic digestion or chemical hydrolysis. This chemical inertness ensures the thread maintains its baseline structural tensile strength indefinitely post-implantation while prompting minimal acute localized inflammatory tissue reactions.

This micro-surgical configuration features an ultra-fine size 8-0 gauge thread diameter, dyed phthalocyanine blue to maximize operational tracking and crisp visualization against blood-filled cavities and fine tissue margins. The system delivers two 24-inch (60 cm) lengths and is configured as a double-armed system, swaged on both ends to micro-format 8 mm BV175-6 style taper point needles utilizing Ethicon's advanced MultiPass needle technology. This ultra-fine round-bodied geometry makes the M8743 an exceptional procurement selection for microvascular anastomoses, peripheral nerve repairs, ophthalmic tracking, and delicate coronary artery bypass grafting procedures.
