Biodegradable Polyesters Driving the Future of Medical Implants and Aesthetic Regeneration
Biodegradable polyester materials are becoming essential in high-end medical devices and medical aesthetics. Through continuous advances in material design and biomedical processing, eSUNMed is accelerating the adoption of medical-grade biodegradable polyesters across implantable devices, tissue regeneration, aesthetic fillers, and personalized 3D-printed medical solutions.
I. Performance Advantages of Biodegradable Polyester Materials
Biodegradable polyester materials such as PLA, PCL, and PLGA offer a range of superior characteristics that make them ideal for biomedical applications.
1. Excellent Degradability
These materials gradually break down into biocompatible small molecules in the body, eliminating the need for secondary surgery.
2. High Biological Safety
Superior biocompatibility supports safe long-term contact or implantation in human tissues.
3. Outstanding Processability
They can be processed into filaments, 3D printing materials, tubes, microspheres, porous scaffolds, and various device components.
4. Strong Designability
Performance can be precisely engineered through:
Selecting and adjusting comonomer types and ratios
Tailoring molecular weight, distribution, end-group modifications, block or branched structures
Controlling orientation, crystallinity, and aggregated-state morphology
Blending to form heterogeneous structures
Systematic design of monomer composition, polymer chain architecture, and condensed-state structures
These capabilities allow eSUNMed to create medical-grade polymers tailored for specific device functions, degradation cycles, and mechanical performance requirements.
II. Applications in Implantable Medical Devices
Thanks to their broad design freedom, ease of processing, mechanical strength, and proven biocompatibility, biodegradable polyester materials are widely applied across multiple clinical fields.
1. Interventional Therapy
Biodegradable coronary stents, occluders, flow-diverting stents, and intravascular thrombosis filtration systems.
2. Neurosurgery
Absorbable cranial bone locks, dura substitutes, nerve repair conduits, and biodegradable coils.
3. Plastic and Maxillofacial Surgery
Absorbable plate-and-screw fixation systems.
4. Otolaryngology
Biodegradable sinus stents, absorbable Eustachian tube stents, and guided tissue-repair membranes.
5. Medical Aesthetics
Injectable facial fillers and implantation threads—areas where eSUNMed’s medical-grade polyester microsphere technology provides natural, long-lasting effects.
6. Orthopedics and Sports Medicine
Absorbable interface screws, suture anchors, rib fixation systems, bone plates, and anterior spinal plating systems.
7. General Surgery
Absorbable hemostatic clips, anti-adhesion barrier membranes, and luminal anastomosis systems.
8. Oncology Treatment
Drug-loaded tumor embolization microspheres and sustained-release films.
9. Regenerative Medicine
Solutions for bone, skin, and organ repair and regeneration.
III. High-End Aesthetic Applications of Biodegradable Polyesters
Biodegradable polyester materials are reshaping medical aesthetics by shifting from simple “space filling” to bioactive tissue regeneration.
Polyester microspheres stimulate collagen neogenesis, enabling natural, long-lasting volumization. As the material gradually degrades, newly formed collagen replaces it, delivering increasingly natural outcomes.
IV. Future Prospects for Medical Device Innovation
Rapid advancements in 3D printing—combined with high-performance biodegradable polyesters—are opening new possibilities for personalized and high-precision medical devices.
1. FDM 3D Printing + Biodegradable Polyesters
Applied in customized implants such as tissue engineering scaffolds, cardiovascular devices, absorbable screws, and bone plates.
Key benefits include:
Direct patient-specific modeling from CT/MRI imaging
Adjustable porosity and gradient structures for better cell growth and vascularization
Production cycles shortened to hours or days, enabling faster clinical treatment
2. Photocuring 3D Printing + Biodegradable Polyesters
A dual-elastic resin developed for LCD/DLP printers supports high-performance orthopedic and rehabilitation footwear.
The one-stop solution covers design, printing, post-processing, and final delivery, addressing cost, efficiency, and quality challenges in flexible photocuring manufacturing and enabling true seamless production.
3. SLS 3D Printing + Biodegradable Polyesters
SLS enables precise, mold-free fabrication of complex, porous, and multi-gradient structures—ideal for personalized medical aesthetics, including injectable fillers and implantation threads.
Laser energy control allows fine tuning of density and microporosity, offering advantages beyond traditional FDM printing.
