Zwitterionic polymers or biocompatible polymers with improved properties for cell encapsulation, coating of devices, or a combination thereof are described. The biocompatible polymer contains a zwitterionic monomer, a monomer with a reactive side chain, and optionally another hydrophobic monomer or a neutral hydrophilic monomer. The zwitterionic polymers are cross-linked with a cross-linker via covalent bond to form a zwitterionic hydrogel in the presence of cells. Also provided, are methods of making and using the zwitterionic polymers.

The present disclosure includes an expandable medical device and outer sheath combination. The outer sheath is capable of being split to form multiple sheath sections that may be peeled back to expose a portion or all of the expandable medical device. The medical device, as well as the outer sheath, may include one or more therapeutic agents for delivery to a treatment area within a patient.

The present disclosure provides methods of improving adhesion of a non-di-(2-ethylhexyl)phthalate (DEHP) plasticized polyvinyl chloride (PVC) to an acrylic-based polymer or an ABS-based polymer. Such methods may comprise blending the acrylic-based polymer or ABS-based polymer with an impact modifier so that a rubber content in the acrylic-based polymer or ABS-based polymer is greater than 12% (w/w). Also provided are components of a device (e.g., a medical device) made by the disclosed methods.

PURPOSE: The present invention provides a polyvinyl chloride resin composition which is superior in heat stability and processability and has less elution from the composition. CONSTITUTION: a polyvinyl chloride resin composition comprising 100 parts by weight of a polyvinyl chloride resin, 10 to 120 parts by weight of di(2-ethylhexyl)terephthalate, and 0.5 to 20 parts by weight of epoxidized vegetable oil having a peroxide number of 5 or less.
