MEDICAL DEVICE HAVING A PHOTOSENSITIZER AND RELATED METHODS
A medical device may include a body and a photosensitizer integrated with the body. The medical device may passively resist colonization of bacteria under ambient light. The medical device may also actively resist colonization of bacteria by releasing reactive oxidative species (ROS) in response to administration of a light dose in a range of 0.5 J/cm.sup.2 to 320 J/cm.sup.2, for a duration between 1 second and 1 hour. The body may be formed by a base resin. The photosensitizer may be compounded with the base resin. The photosensitizer may be imbibed into the base resin. The medical device may include a coating disposed on a surface of the body. The photosensitizer may be disposed within the coating. The medical device may include a catheter adapter and a catheter extending distally from the catheter adapter. The catheter may be co-extruded with the photosensitizer and another material.
MATRICES COMPRISING A MODIFIED POLYSACCHARIDE
The present invention discloses a matrix comprising a modified polysaccharide consisting of repeating disaccharide units whereby in at least 11% of the disaccharide units one primary alcohol group is oxidized into a carboxylic acid group.
Polyisoprene latex graphene composites and methods of making them
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 the composite exhibit good mechanical properties with improved ageing resistance.

Methods, Systems and Devices for Post-Fabrication Drug Loading
A post-fabrication method for drug loading a medical device with an active pharmaceutical ingredient (API). Such medical devices can include a polymer matrix, where the polymer matrix, after exposure to a loading solution with the API, can exhibit a degree of swelling of the polymer matrix and/or a degree of swelling in which the polymer matrix increases in a dimension along an axis. Medical devices including a polymer matrix and an API are provided, where the API is loaded into the polymer matrix by adsorption and/or swelling after fabrication of the polymer matrix, wherein the medical device provides a substantially sustained release of the API for an extended period of time. The medical devices include intravaginal rings (IVR). Methods of treating a subject using the disclosed medical devices are also provided, including treating a subject with an IVR with one or more APIs loaded therein.
Two component sealing systems including synthetic matrices and biosynthetic adhesives for sealing resected surfaces of organs to control bleeding, fluid leaks and air leaks
A method of sealing a resected surface of an organ includes applying a synthetic matrix to a resected surface of an organ, and applying an adhesive on the synthetic matrix so that the adhesive penetrates through interstices of the synthetic matrix for contacting an interface between the synthetic matrix and the resected surface of the organ. The method includes curing the adhesive for bonding the synthetic matrix to the resected surface of the organ. The synthetic matrix is a non-woven mesh made of polyglactin 910 or any other synthetic or non-synthetic fabric having a similar porosity or density. The adhesive is a biosynthetic or a synthetic adhesive. After penetrating through the pores of the synthetic matrix and curing, the cured biosynthetic or synthetic adhesive mechanically interlocks with the synthetic matrix for adhering the synthetic matrix to the tissue for creating a sealing barrier.
