Introduction
Cervical cerclage Tape, widely known as Shirodkar suture, is a specialized procedure for reinforcing the cervix in cases of cervical insufficiency—vital for preventing preterm birth or late miscarriage Unlike common McDonald sutures, Shirodkar involves embedding tape within the cervical tissue, reducing exposure and potential infection.
We manufacture a complete range of Cervical Cerclage Tapes for optimal cervical support. For orders or queries, kindly drop us a message.
1.Cervical Cerclage Tape Types & Techniques
Shirodkar Cerclage:
Placed transvaginally at the internal os through a dissected submucosal tunnel, anterior and posterior, tied posteriorly then buried under cervical mucosa. Offers higher placement than McDonald and may lessen infection risk
Modified Shirodkar:
Involves precise tissue dissection to bury the knot and tape completely—all beneath the mucosal surface—to promote biointegration and easier removal
2. Composition & Material
Our cervical cerclage tape is:
- Material: Non‑absorbable, ultra‑fine polyester (e.g., Mersilene)
- Dimensions: 5 mm width, ~0.3 mm thickness; woven structure offers exceptional strength and reliability
Needles:
- Unlike conventional manufacturers who use channel needles, MicroFine employs a drilled-end needle in combination with an advanced ultrasonic tapering process.
- This specialized method converts the flat end of the 5 mm polyester tape into a smooth, round, monofilament-like structure, which fits securely into the drilled-end needle.
3. Strength & Performance
- Mechanical Integrity: The woven polyester tape delivers superior tensile strength suitable for sustained cervical support throughout pregnancy.
- Clinical Outcomes: Studies affirm that Shirodkar tape placement enhances cervical length and prolongs gestation (up to ≥ 37 weeks in elective cases), with success rates of 80–90 %, comparable or better than McDonald approaches
- Infection Control: Fully buried and embedded knot and tape reduce infection and erosion risk—well-supported by literature on modified Shirodkar outcomes.
4. Microfine’s Specialized Technology
| Feature | Traditional (Channel Needle) | Microfine Surgical Devices |
| Needle Type | Channel needles (bulk, force-fit tape) | Drilled-end needles designed to accommodate a monofilament-tapered tape tip |
| Tape Insertion | Requires channel to fit full tape width | Flat tape tip is reshaped to < round diameter; inserted cleanly |
| Precision | Bulkier passage, more tissue resistance | Smooth insertion; less trauma |
| Needle Size | Larger, less maneuverable | Slim drilled-end needles—enhanced tissue handling |
| Tissue Trauma | Slightly higher risk | Reduced trauma; safer submucosal tunneling |
| User Experience | Bulkier handling, limited finesse | Ergonomic, high-precision delivery enhances surgeon control |
5. Material & Biocompatibility
-
- Polyester Tape Base: High tensile strength, non-degradable, minimal
- Monofilament-like Tip: Fused to reduce fraying and minimize bacterial
- Needles: Medical-grade stainless steel with polished finish for smooth tissue insertion, and precision-drilled ends with proprietary taper control.
Summary
Microfine’s Shirodkar tape sets a new standard with:
- High-strength woven polyester construction
- Innovative needle-and-tape interface reducing tissue trauma
- Enhanced surgical control and patient safety
- Clinically validated outcomes matching established techniques
Final Note: At Microfine Surgical Devices, we are committed to advancing surgical biomaterials. Our cervical cerclage tape demonstrates excellence through rigorous design, clinical innovation, and dedication to maternal–fetal health.
