The disclosed technology provides thermoplastic polyurethane compositions having antimicrobial properties while still maintaining good physical properties and good non-fouling properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a base polymer and further includes mixing in a non-fouling additive, where the antimicrobial additive is chemically held in the composition and the antimicrobial and non-fouling additives do not negatively impact each other's effectiveness.

Antimicrobial, non-thrombogenic polymer composition

The disclosed technology provides thermoplastic polyurethane compositions having non-leaching antimicrobial properties while still maintaining good physical properties, methods of making the same, and articles, including medical devices, made from such compositions. The disclosed technology includes a process of making an antimicrobial polymer composition, where the process includes mixing an antimicrobial additive into a polymeric material; wherein said polymeric material comprises a polymeric backbone made up of urethane linkages derived from a polyisocyanate and a polyol; and wherein said mixing occurs under conditions that result in the breaking of a minority of said urethane bonds resulting in reactive isocyanate groups; and wherein two or more of said reactive isocyanate groups react with said antimicrobial additive to covalently bond said antimicrobial additive into the polymeric backbone of said polymeric material; resulting in an antimicrobial polymer composition.

Antimicrobial thermoplastic polyuethanes

A biocidally active polymer composition formed from an oligomeric or polymeric additive and a thermoplastic polyurethane polymer is disclosed. The biocidally active polymer may further include a non-fouling and/or non-thrombogenic polymer. The biocidally active polymer provides biocidally active properties, and may also provide non-fouling and/or non-thrombogenic properties. The composition is particularly useful in articles and materials for medical applications.

Biocidally active polymer compositions

A surface-modified polymer composition formed from an oligomeric or polymeric additive and a base polymer is disclosed. The surface-modified polymer provides non-fouling and/or non-thrombogenic properties. The composition is particularly useful in articles and materials for medical applications.

Surface modified polymer compositions

A voltage controlled oscillator compising a distributed coupled resonator (DCR) that desirably produces a low noise signal source with reduced phase hits in comparison to a high Q resonator, such as a ceramic and SAW (Surface Acoustic Wave) resonator based oscillator.
