What makes purified gelatin the biomaterial of choice for embolization?
Embolization, a medical procedure that involves intentionally blocking blood vessels or abnormal tissue growth, requires a biomaterial that possesses specific properties to ensure its effectiveness and safety.
Three key reasons why purified gelatin has emerged as the preferred biomaterial for embolization: 1. erived from the natural protein collagen, gelatin is inherently biocompatible with the human body meaning it is less likely to trigger immune responses or cause adverse reactions, promoting better patient outcomes. It is also biodegradable, meaning it breaks down naturally in the body over time, minimizing the risk of longterm complications associated with permanent implants.
2. Gelatin offers a precise degradation rate that can be tailored based on the specific needs of the procedure. This controlled breakdown ensures that the embolizing material is gradually replaced by natural tissue as the body heals, preventing complications and allowing for a predictable clinical outcome.
3. Gelatin can be easily molded into different shapes and sizes, including microspheres, which are commonly used in embolization procedures. This flexibility in shaping and control over particle size allows for customization of the embolizing agents, enabling physicians to target specific vessels or tissues more accurately.
How is gelatin advancing embolization applications?
Typically, embolization is achieved using materials like coils, particles, or liquids to block or reduce blood flow in specific blood vessels or tissues. In recent years, new types of gelatin-based embolic materials have become an increasingly popular choice, offering many advantages. Thanks to its mechanical versatility, gelatin can be used in either microspheres or gel formats and to treat a wide range of conditions such as arteriovenous malformations, tumors, and aneurysms.
The recent availability of improved gelatinbased biomaterials with customizable properties, consistent quality, and proven biocompatibility, is providing a new, reliable solution for pharmaceutical manufacturers and medical professionals seeking the most effective embolization materials. For example, Rousselot s X-Pure gelatins are currently used in approved and marketed medical devices in the United tates and Asia. We are seeing growth in the development of new gelatin-based embolic devices in other markets such as Asia, which are rapidly expanding onto the global stage.
How to choose a gelatin for embolization?
While gelatin is a preferred biomaterial for embolization, it is not without its challenges. electing the right biomaterial from the start of the R& process is key to achieving success. ere are the most important features to look out for when selecting a gelatin for embolization
Customization: Tailoring gelatin properties to meet the specific requirements of different embolization procedures can be time-consuming and requires careful formulation and testing. Choosing a gelatin supplier that offers customized gelatin ensures seamless product manufacturing and optimal performance.
Degradation Rate Control: The degradation rate can be tailored based on the specific needs of the product developed for the embolization procedure, preventing complications and allowing for predictable performance.
Consistency: Ensuring consistent properties in gelatin microspheres or embolic agents is crucial. ariability in gelatin properties can lead to unpredictable results, making quality control and standardization essential.
Purity: Choosing purified gelatins with low levels ofendotoxins helps to ensure safe and effective medical devices.
Availability and Sourcing: /ack of availability of high-quality gelatin for medical use can impact the consistency and reliability of the embolic material. Choosing a well-established gelatin supplier with a solid track record and a secure supply chain is essential to ensure a reliable and stable source of biomaterials.
Compatibility: Gelatin can be engineered to be compatible with various imaging modalities, allowing interventional radiologists to visualize the embolic material s precise location during the procedure. This real-time imaging can enhance the accuracy and safety of embolization.
Documentation: The new European 0edical evice Regulation (0 R) requires rigorous documentation, quality assurance, and product performance assessments. All Rousselot products come with supporting documentation for compliance of medical devices with the new 0 R requirements ((EU) 201 / ), documented traceability up to the farm (I O 22 2-2), validated viral inactivation (I O 22 2-3) and IPEC G0P Compliance.
Why choose X-Pure?
Rousselot s X-Pure gelatines have been designed to address the specific requirements of embolization procedures. Offering customizability, purity, and consistency, X-Pure serves as the ideal foundation for creating various embolic agents like gelatin microparticles/microspheres and hydrogels. X-Pure is compatible and easily blended with a wide variety of different drugs, cells, and molecules for accurate drug delivery and imaging. As such, X-Pure can support a wide range of embolization applications, including transarterial embolization (TAE), transarterial chemoembolization (TACE), and radioembolization.
Rousselot s X-Pure range has been developed to ensure maximum quality and safety, with endotoxin levels of <10 endotoxin units (EU)/g. All X-Pure gelatins support regulatory compliance with key international guidelines. This includes traceability, readily available documentation, and validated viral safety.
