Innovative Intravascular Micro-Filter by Sunresin
Innovative Intravascular Micro-Filter by Sunresin
Background: Unmet Needs in Blood Purification Therapies
Blood purification techniques—such as hemoperfusion and hemodialysis—are essential methods for removing toxins, metabolites, drugs, and harmful substances from the bloodstream. These treatments are widely used in managing liver failure, kidney dysfunction, drug poisoning, and metabolic disorders.
However, conventional external blood purification systems face several limitations:
- Dependency on external circulation: Blood must be drawn out of the body and circulated through pumps and monitoring devices.
- High operational requirements: Treatment must be conducted in well-equipped hospitals, posing challenges for patients in remote regions or those requiring long-term therapy.
- Physiological stress: Extracorporeal circulation requires anticoagulation and large volumes of replacement fluids, increasing treatment risks and burden.
These limitations highlight the urgent need for a safer, simpler, and more accessible alternative to conventional extracorporeal treatments.
Sunresin’s Solution: A Miniaturized Intravascular Filter
To address these challenges, Sunresin has developed an innovative intravascular micro-filter—a compact device designed to be placed directly inside a blood vessel via standard catheterization techniques. This solution brings blood purification inside the body, providing a fundamentally new approach to toxin removal.
Key Advantages
1. Body-Compatible Adsorption Technology
The filter integrates engineered adsorptive materials with excellent biocompatibility, allowing it to selectively capture toxins or harmful metabolites directly from circulating blood while avoiding disruption to normal blood components.
2. Minimally Invasive, Easily Replaceable Design
Once the filter reaches saturation, clinicians can remove and replace it via its handle using a simple catheter-based procedure.
This design makes maintenance safer and significantly easier compared with replacing traditional extracorporeal cartridges.
3. Suitable for Hospital and Home-Based Care
Because blood does not need to leave the body:
- No external pump systems
- No large anticoagulant doses
- No complex temperature or fluid management
Patients can receive treatment not only in medical facilities but potentially also in home-care environments, reducing financial and physical burden and improving accessibility for chronic or remote-area patients.
Clinical and Industrial Impact
Sunresin’s intravascular micro-filter represents a meaningful step forward in blood purification technology, offering:
- A safer, more patient-friendly alternative to traditional extracorporeal systems
- A minimally invasive method suitable for repeated or long-term therapy
- A platform technology adaptable for various medical conditions involving harmful metabolites or circulating toxins
This innovation reinforces Sunresin’s commitment to advancing medical adsorption materials, biocompatible polymers, and clinical purification technologies, contributing to improved patient outcomes and healthcare accessibility.
Supporting Healthcare Innovation Through Advanced Materials
Sunresin continues to expand its biomedical materials portfolio, developing solutions for blood purification, protein separation, bioprocessing, and toxin removal. The intravascular filter reflects the company’s integrated strengths in:
- functional material design
- polymer engineering
- biosafety research
- medical application development
Sunresin will continue working with clinicians, hospitals, and research partners to accelerate real-world application of next-generation blood purification technologies.
