| 4-0 | 0.98 N | 1.96 N | USP/EP |
DesmoMid (Polypropylene)
View product| USP Size | Knot-Pull Strength | Straight-Pull Strength | Standard |
|---|---|---|---|
| 2-0 | 2.50 N | 5.00 N | USP/EP |
| 3-0 | 1.65 N | 3.30 N | USP/EP |
| 4-0 | 0.88 N | 1.76 N | USP/EP |
| 5-0 | 0.46 N | 0.92 N | USP/EP |
All values meet or exceed USP/EP pharmacopeial minimum requirements. Full tensile data across all USP sizes is available upon request.
How Long Do Desmo Care Sutures Maintain Strength?
Tensile strength retention — the percentage of original breaking strength maintained over time — is critical for matching suture performance to tissue healing rates. The table below shows in-vivo strength retention profiles for Desmo Care absorbable and long-term sutures.
| Product | 1 Week | 2 Weeks | 3 Weeks | 6 Weeks | 90 Days |
|---|---|---|---|---|---|
| DesmoNex | ~85% | 75% | 40% | <10% | 0% |
| DesmoNex Rapid | 50% | <20% | 0% | 0% | 0% |
| Absorbex | ~85% | 70% | 50% | <10% | 0% |
| DesmoCryl | ~80% | 65% | 40% | <10% | 0% |
| DesmoCapro | ~90% | ~88% | ~85% | ~82% | 80% |
| DesmoPol | ~80% | 70% | ~60% | 50% | <20% |

How Are Desmo Care Sutures Manufactured?
Facility
Sutures are produced in a 35,000 m² purpose-built manufacturing campus housing ISO Class 100 (Grade A) and ISO Class 10,000 cleanroom environments. Production zones are continuously monitored for particulate count, temperature, and humidity.
Sterilization is performed using validated ethylene oxide (EO) cycles in accordance with ISO 11137. Every sterilization batch is released only after passing parametric release criteria and sterility verification testing.
Quality Control
Quality inspection occurs at every production stage: incoming raw material testing, in-process dimension and strength checks, packaging integrity verification, and final batch release testing against USP/EP pharmacopeial specifications.
A team of 300+ employees — including dedicated QA/QC engineers, validation specialists, and regulatory affairs professionals — ensures every suture that leaves the facility meets its registered specification. Over 40 years of manufacturing experience underpins the consistency of every batch.

Clinical Evidence FAQ
Are Desmo Care sutures safe for cardiovascular procedures?
Yes. DesmoPol (PDO monofilament) and DesmoMid (polypropylene monofilament) are used in cardiovascular surgery including vessel anastomosis and cardiac repair. Both products pass all ISO 10993 biocompatibility tests, including cytotoxicity, sensitization, and implantation, and are CE marked under EU MDR 2017/745 for Class IIb indication.
Do Desmo Care sutures meet European medical device regulations?
Yes. All Desmo Care sutures are CE marked under EU MDR 2017/745, the most demanding medical device regulatory framework in the world. CE conformity is assessed by an independent EU Notified Body and requires comprehensive technical documentation, clinical evidence, post-market surveillance, and ongoing quality management system audits under ISO 13485:2016.
How does Desmo Care ensure batch-to-batch consistency?
Desmo Care operates an ISO 13485:2016 certified Quality Management System with statistical process control at every manufacturing stage. Incoming raw materials undergo identity and purity testing. In-process controls monitor tensile strength, diameter, and surface finish. Each finished batch is released only after passing full USP/EP pharmacopeial testing including tensile strength and sterility verification. Complete traceability is maintained from raw material lot to finished product batch.
Can I request biocompatibility test certificates?
Yes. Biocompatibility test reports, ISO 13485 certificates, CE Declaration of Conformity, and sterilization validation data are available to qualified healthcare professionals, purchasing authorities, and regulatory bodies upon request. Contact our quality team via the clinical documentation request form.
What is the shelf life of Desmo Care sutures?
Desmo Care surgical sutures have a shelf life of 5 years from the date of manufacture when stored under the recommended conditions: below 25°C, relative humidity below 60%, away from direct sunlight and ionizing radiation. Shelf life is validated per ISO 11607 accelerated aging protocols. Each product package carries the expiry date and storage conditions on the label.
