Bioster

What Bioster does

BIOSSTER, a.s. is a Czech private medical device manufacturer and radiation services provider headquartered in Veverská Bítýška, Czech Republic, operating since approximately 1970. The company operates two distinct business lines. The first is the Traumastem haemostat product line — a portfolio of sterile, resorbable, biocompatible haemostatic devices made from oxidized non-regenerated cellulose (cotton-based), available in multiple formats including fibrillar (FAM Trium, FAM Strata, FAM OcW), net (TAF, TAF Light), powder (POWDER, P), dental cubes (NEW Dent), and an endoscopic applicator (ENDO Applicator). These products provide capillary, venous, and minor arterial bleeding control across general, trauma, vascular, thoracic, neurosurgical, gynaecological, urological, ENT, and dental procedures, with documented antimicrobial activity against antibiotic-resistant organisms.

The second business line comprises radiation services: gamma radiation sterilization for medical devices, pharmaceuticals, veterinary products, herbs, and food packaging; radiation crosslinking of plastics for industrial clients in automotive, electronics, and aerospace; and innovative applications including medical cannabis decontamination and Sterile Insect Technique (SIT) research. Both lines are served from the same single facility, allowing fixed-cost amortization of the cobalt-60 irradiation infrastructure.

The business model is B2B direct sales conducted via email to specialized department representatives (Sales, Marketing/Regulatory, Radiation Services), with no public e-commerce platform. Products are sold on a per-unit basis; radiation services are quote-based with pay-as-you-go billing. The company holds ISO 13485:2016, ISO 9001:2016, EU MDR, and GMP certifications, and markets its haemostats under the Traumastem, Emoxicel, and Celstat trademarks to a global customer base including hospitals in the Czech Republic, Mexico, and Bulgaria.

Core offering

Bioster manufactures and sells a portfolio of sterile, resorbable haemostatic medical devices made from oxidized non-regenerated cellulose, marketed under the Traumastem brand in multiple formats (woven, knitted, powder, dental, applicator) for open, minimally invasive, and endoscopic surgical procedures. In parallel, the company operates a contract gamma radiation service center providing sterilization for medical devices, pharmaceuticals, cosmetics, food, and feed, as well as polymer crosslinking and innovative gamma-radiation applications for industrial customers.

Product overview

Bioster is a Czech medical device company producing haemostats under the Traumastem brand and providing radiation services. The Traumastem product portfolio consists of sterile, resorbable, biocompatible haemostats made from oxidized natural cellulose (cotton) designed to stop capillary, venous, and minor arterial bleeding. The product line includes multiple haemostat forms: Traumastem FAM OcW (microwadding), Traumastem FAM Trium (multilayer fibrillar), Traumastem FAM Strata (single-layer fibrillar), Traumastem NEW Dent (dental cubes), Traumastem TAF and TAF Light (haemostatic nets), Traumastem POWDER and P (haemostatic powders), and the Traumastem ENDO Applicator (accessory for powder delivery in endoscopic surgery). All haemostats exhibit bactericidal effect against a broad range of microorganisms including antibiotic-resistant bacteria. In addition to haemostats, Bioster offers radiation services including gamma radiation sterilization, radiation crosslinking of plastics, and innovative applications such as medical cannabis treatment and the Sterile Insect Technique.

Direct peers

• Ionisos: Ionisos is a European contract gamma and E-beam sterilization provider with multiple ISO- and GMP-certified facilities. Comparable to Bioster because both are European specialists offering GMP gamma sterilization for medical devices, pharmaceuticals, and growing applications such as medical cannabis.
• Baxter International: Baxter markets FloSeal hemostatic matrix and Tisseel fibrin sealant for surgical bleeding control, directly competing against Traumastem in the same operating-room budgets. Both companies target the same surgical specialty buyers with hospital-wide hemostasis solutions.
• Becton Dickinson (BD): BD supplies a portfolio of surgical haemostasis and biosurgery products to hospitals globally. It competes with Bioster across hospital surgical procurement and shares exposure to single-use absorbable device demand in operating rooms.
• BGS Beta-Gamma-Service: BGS is one of Europe's longest-established gamma radiation sterilization service providers, operating cobalt-60 facilities in Germany. Comparable to Bioster's sterilization business because both are European contract gamma sterilizers serving medical, pharmaceutical, and industrial customers with similar regulatory and quality requirements.
• Sterigenics (Sotera Health): Sterigenics is the largest global contract gamma and E-beam sterilization provider serving medical device, pharmaceutical, and biotech customers. It is comparable to Bioster's contract sterilization business as both offer GMP-validated cobalt-60 gamma irradiation services to healthcare manufacturers under the same regulatory regime.
• Ethicon (Johnson & Johnson): Ethicon's SURGICEL is the benchmark oxidized cellulose haemostat and the most direct competitor to Bioster's Traumastem line. Both companies sell sterile absorbable haemostats to surgical departments in the same hospital accounts across general, vascular, thoracic, and oncologic surgery.
• Advanced Medical Solutions: Advanced Medical Solutions (UK) develops RESORBA absorbable haemostats and wound closure products, many based on oxidized cellulose technology. It is a comparable European specialist competing for the same niche haemostat and tissue-sealant categories served by Traumastem.
• Integra LifeSciences: Integra develops specialty surgical haemostats and regenerative devices for neurosurgery, ENT, and general surgery. Comparable to Bioster because both companies focus on niche surgical specialty adjacencies where larger competitors have less share, and both sell absorbable haemostat products through hospital sales channels.
• Teleflex (Z-Medica): Teleflex acquired Z-Medica and its QuikClot hemostatic gauze line, competing with oxidized cellulose haemostats in trauma, emergency, and surgical settings. Comparable to Bioster because both serve bleeding-control use cases in hospitals and pre-hospital care.

Broad incumbents

• STERIS: STERIS is a large, diversified sterilization and infection-prevention company offering contract sterilization, capital equipment, and consumables. Comparable to Bioster's radiation services as an incumbent with broader modalities (gamma, EtO, steam, X-ray) addressing the same medical and pharmaceutical customers.
