Medical hollow tube

A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.

Bioactive coatings

Embodiments include polymers with antimicrobial and antithrombogenic groups bound to a single polymer backbone, an antimicrobial polymer blended with an antithrombogenic polymer, and medical devices coated with the antimicrobial and antithrombogenic polymer or polymeric blend.

MEDICATION INFUSION COMPONENTS AND SYSTEMS

This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

END-CAPPED POLYISOBUTYLENE POLYURETHANE

A polymeric material includes a polyisobutylene-polyurethane block copolymer. The polyisobutylene-polyurethane block copolymer includes soft segments, hard segments, and end groups. The soft segments include a polyisobutylene diol residue. The hard segments include a diisocyanate residue. The end groups are bonded by urea bonds to a portion of the diisocyanate residue. The end groups include a residue of a mono-functional amine.

Durable photopolymerizable cross-linked anti-fouling coatings

Durable, anti-fouling, crosslinked zwitterionic coatings that are grafted to the surface of a substrate through covalent bonding are disclosed. When exposed to a light source, zwitterionic monomers react with a crosslinker and with activated radicals at the surface of the substrate, simultaneously forming the crosslinked zwitterionic coating and anchoring it to the surface of the substrate. Photomasking techniques can be used to micropattern the zwitterionic coatings. The zwitterionic coatings can be applied to a variety of substrates, including medical devices and systems.
