Explore our high-performance absorbable sutures, barrier meshes, and industrial filtration screens manufactured under ISO 13485 & EU MDR cleanroom standards.
Plain Catgut remains one of the foundational bio-absorbable surgical wound closure materials utilized across global clinical practices, obstetrics, gynaecology, urology, and gastrointestinal surgeries. Manufactured from high-purity submucosal fibrous tissue isolated from bovine (cattle) or ovine (sheep) intestines, Plain Catgut is a natural monofilament suture composed predominantly of collagen fibers. Its unique biochemical identity allows for predictable enzymatic degradation within living mammalian tissue, eliminating the need for secondary surgical removal.
As leading medical procurement officers and clinical distributors navigate international supply chains, securing a reliable OEM/ODM partner who operates under stringent regulatory compliance is paramount. As a top-tier China Plain Catgut factory and global exporter, our facility bridges high-capacity precision manufacturing with rigorous international standards (including ISO 13485 QMS and EU MDR Regulation 2017/745 protocols). Our technical commitment guarantees that every suture strand delivers a minimum of 1.1 times the standard USP tensile strength requirement, ensuring uncompromised knot security and intraoperative reliability.
Information Gain Insight: Unlike synthetic absorbable polymers (such as PGA or PGLA) which degrade via hydrolytic cleavage, Plain Catgut undergoes natural proteolytic breakdown by endogenous tissue enzymes. This characteristics makes it uniquely suited for rapidly healing tissues requiring short-term mechanical support (7 to 10 days of critical tensile retention) in high-vascularity sites.
The manufacturing process begins with the rigorous extraction of the intestinal submucosal layer, rich in Type I collagen. The ribbons undergo alkaline treatment, enzymatic cleaning, and mechanical splitting into uniform ribbons. Multiple ribbons are spun under controlled tension to form a single monofilament structure, followed by precision electronic centerless grinding to yield smooth surface finishing and exacting dimensional tolerances.
Our manufacturing philosophy centers on "Healing Beyond Comfort." Operating out of state-of-the-art cleanrooms (Class 100,000 / ISO Class 8 equivalent), our manufacturing ecosystem covers the entire vertical value chain—from raw collagen ribbon processing to automatic needle swaging, primary foil barrier sealing, and validated Ethylene Oxide (EtO) terminal sterilization.
Full regulatory compliance with CE Marking and EU Regulation 2017/745. Comprehensive Technical Documentation (STED) ready for global registration.
Every lot undergoes rigorous tensiometer testing. Our knot pull-out strength exceeds USP baseline metrics by at least 10%, offering superior safety margins.
Extensive selection of suture sizes (USP 8/0 to USP 3), pre-attached with 300-series stainless steel micro-ribbed needles in various curvature profiles.
Our production line is empowered by a workforce where over 70% of team members are skilled women specialists in micro-assembly and quality control.
Needle attachment is a critical vector for intraoperative success. We utilize precision laser-drilled needles crafted from AISI 302/304 premium surgical steel. The ribbed geometry of our needles prevents rotation in the needle holder, allowing surgeons precise control during tissue passage. Primary packaging utilizes hermetically sealed aluminum foil sachets containing isopropyl alcohol and distilled water fluid medium to maintain fiber pliability and prevent collagen desiccation.

As healthcare systems undergo systemic shifts toward supply chain resilience and cost optimization, global procurement directors must anticipate emerging regulatory and market dynamics. Key procurement trends shaping the absorbable suture sector include:
Health authorities worldwide (including the US FDA, EMA, and China NMPA) enforce strict traceability regulations regarding Transmissible Spongiform Encephalopathies. Sourcing Plain Catgut requires suppliers to provide certified BSE/TSE-free veterinary health credentials from closed herds, ensuring zero risk of prion contamination.
Distributors in North America, South America, Europe, and the Middle East are increasingly moving away from high-margin multinational monopoly brands toward direct OEM factory partnerships. By collaborating directly with a certified Chinese manufacturer, buyers can customize artwork, needle combinations, box quantities, and multi-language labeling while retaining high gross margins.
National regulatory bodies no longer accept basic Certificate of Free Sale (CFS) documents. B2B contracts now hinge on suppliers capable of providing full Common Technical Documents (CTD), Biocompatibility Reports (ISO 10993), EtO Residual Analysis (ISO 10993-7), and Accelerating Shelf-Life Testing data.
While synthetic absorbable polymers (such as Polydioxanone PDS and Polyglactin 910) have gained market share in orthopedic and vascular applications, Plain Catgut maintains an irreplaceable position in global surgery due to its cost-efficiency, organic absorption profile, and unmatched knot pliability. Future developments focus on:
Integration of bioactive silver nanoparticle coatings to impart broad-spectrum antibacterial characteristics without altering collagen absorption rates.
Robotic centerless grinding systems that eliminate microscopic surface irregularities, yielding ultra-consistent knot sliding friction.
Transition toward fully recyclable outer display cartons and zero-plastic secondary packaging for bulk distributor consignments.
Direct answers to essential technical, regulatory, and commercial queries from hospital buyers and medical importers:
Plain Catgut is untreated natural collagen that degrades rapidly, retaining critical tensile strength for 7 to 10 days with total absorption within 60 to 90 days. Chromic Catgut is treated with trivalent chromium salts, which delays enzymatic digestion, extending tensile strength retention to 18–21 days and complete absorption to 90–120 days.
Each suture thread is sealed in a dual-foil airtight packet containing a preserving solution of isopropyl alcohol, water, and trace conditioning agents. This prevents collagen embrittlement and ensures immediate out-of-pack pliability during surgery.
Yes. We offer complete turnkey OEM/ODM services. Global brand owners can specify needle curvature (1/2 circle, 3/8 circle, 1/4 circle), needle point geometry (taper point, reverse cutting, cutting edge), thread lengths (45cm to 150cm), and custom brand packaging artwork.
