TPU catheters
What it is
Medical catheters in TPU (Thermoplastic Polyurethane) are devices used for numerous applications — vascular access (central, peripheral, port-a-cath), urinary drainage, enteral nutrition, dialysis, cardiovascular interventional procedures. TPU is one of the dominant materials in modern catheterization due to its unique combination of flexibility, strength, biocompatibility and processability.
Critical characteristics of medical TPU:
- Flexibility: allows navigation in tortuous vessels without causing trauma
- Memory: maintains desired shape after manipulation
- Kink resistance: does not bend or obstruct during use
- Proven biocompatibility: complete ISO 10993 testing
- Sterilizable: by gamma or EtO
- Processable: extrusion and injection with micrometric precision
- Low thrombogenicity: especially for vascular catheters
Variations include TPU with radiopaque additives (visible on X-ray), with hydrophilic coatings (increasing insertion ease), with antimicrobial coatings (reducing catheter-related infection).

Value proposition
For premium catheter manufacturers selling to hospitals and health systems:
- CLABSI and other infection reduction: vascular catheters with medical-grade TPU combined with antimicrobial coatings reduce central line-associated infections by 40 to 60% in controlled studies — direct financial impact for hospitals (CLABSI costs USD 15,000 to 50,000 per event)
- Patient comfort and trauma reduction: TPU flexibility at body temperature, combined with hydrophilic coatings, reduces insertion trauma and discomfort during prolonged use
- Ease of use for medical team: kink resistance, radiopaque visibility and shape memory facilitate procedures and reduce insertion time
- Versatility for different uses: the same medical TPU technology base serves vascular, urinary, enteral nutrition, dialysis catheters — enables broad portfolio with economies of scale
- International regulatory compliance: TPU with USP Class VI certifications, complete ISO 10993 and traceability opens access to FDA and CE mark markets — viable international expansion
- Support for emerging interventional procedures: growth of cardiology, radiology and minimally invasive surgery demands specialized catheters — high value-added segment in expansion
