Electrospinning Medical Device: Bioresorbable Electrospun Nonwovens From Concept to Product

Synthetic polymer-based textiles have been used for medical applications for decades and represent a staple production technique on par with injection molding and machining. Textiles are provided in a number of techniques, such as knits, braids, woven fabrics, monofilaments, films, and various nonwovens. For many medical applications, however, traditional textiles do not meet performance requirements. […]

Bioresorbable Polymer Design: Advantages of a “Block Copolymer”

Poly-Med’s bioresorbable polymers offer customized product options for our customers. Copolymers present advantages not usually seen in homopolymers. For this reason, many of the bioresorbable polymers are a copolymer type, such as PGLA. We take this advantage one step further and involve the polymer architecture to modulate the properties of a given material. For example, […]

Bioresorbable Polymer Processing: Keys from the Field

A wide variety of implantable medical devices are created using plastic components, which involve the use of more “traditional” polymers such as polypropylene and polyethylene terephthalate (PET) as well as advanced and tailored materials like polyetheretherkeytone (PEEK) and polyvinylidene fluoride (PVFD). A segment of the implantable device market utilizes an increasingly specialized polymer subset that […]

Bioabsorbable Polymers: Drying Degradable Materials Appropriately

A key concern for the use of bioresorbable materials is the presence of water or moisture within an bioresorbable device. As the majority of bioresorbable polymers degrade by hydrolytic degradation, minimizing water content is of the utmost importance for enhancing device life and maintaining functionality. In general, bioresorbable polymers degrade by bulk hydrolysis of main-chain […]
