Generally, the invention is in relation to the field of drug delivery devices to augment standard radiation therapy and methods of making and using same. Specifically, this technology utilizes a controlled release of drug from a coated balloon for local intratumoral drug delivery to breast tissue to supplement or replace standard radiation therapy.

In some aspects, provided herein are antimicrobial compositions comprising partially esterified polygalacturonic acid and certain fatty acids (e.g., caprylic acid). In some embodiments, the antimicrobial composition may be administered (e.g., topically or orally) to a subject, such as a human patient to treat an infection (e.g., an infection comprising a biofilm). In some aspects, improved catheters are provided.

The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

Lubricious coatings for medical devices and their uses are described.

The present invention is in the fields of medicinal chemistry, biotechnology and pharmaceuticals. The invention provides compositions comprising one or more collagen mimetic peptides, optionally attached to one or more therapeutic compounds or one or more imaging compounds, for use in methods of treating, preventing, ameliorating, curing and diagnosing certain diseases and physical disorders in humans and veterinary animals, as well as methods of manufacturing such composition. The invention also provides medical devices comprising one or more such compositions of the invention. The invention also provides methods of use of such compositions and devices in treating and diagnosing certain diseases and physical disorders in humans and veterinary animals, including ocular diseases or disorders, skin diseases or disorders, certain cancers, particularly intraluminal cancers, gastrointestinal diseases or disorders, genitourinary tract diseases or disorders, fibrotic diseases/disorders and rheumatic diseases/disorders.

The present application relates generally to tubes, such as thin walled catheter liners with small wall thicknesses (e.g., less than 1 mm), including crosslinked fluoropolymers, e.g., crosslinked poly(tetrafluoroethylene). The disclosure further provides methods of manufacturing such tubes and systems for manufacturing such tubes.

Zwitterionic carboxybetaine copolymers and their use in coatings to impart non-fouling and functionality to surfaces, particularly surfaces of blood-contacting medical devices.

A neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the tubular body includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, an outer jacket surrounding the helical coil, and an opening at the distal end. Adjacent windings of the helical coil are spaced progressively further apart in the distal direction. The opening at the distal end of the tubular body is enlargeable from a first inside diameter for transluminal navigation to a second, larger inside diameter to facilitate aspiration of thrombus into the lumen.

High strength biomedical materials and processes for making the same are disclosed. Included in the disclosure are nanoporous hydrophilic solids that can be extruded with a high aspect ratio to make high strength medical catheters and other devices with lubricious and biocompatible surfaces.
