Abstract: The embodiments disclosed herein relate to catheter assemblies. The catheter assemblies can include a multi-lumen catheter, a junction hub, and extension legs. The catheter assemblies can also include a sheath that includes a membrane that is permeable to one or more gases and impermeable to one or more liquids or solids. The catheter assemblies can be configured to deliver food to a patient through a first lumen, and simultaneously vent or aspirate one or more gases from the patient through a second lumen. The catheter assemblies can also include preformed catheters that assume a non-linear three-dimensional shape when in a relaxed state.

Abstract: A cover for use in breast feeding or bottle feeding an infant is disclosed, wherein the 5 cover (11) is formed from a sheet of fabric or the like shaped so that it may be comfortably draped around a mother's torso during breast feeding in order to allow discrete breast feeding of an infant. The cover is provided with a single strap means (15) to fit over a shoulder of the mother to prevent the cover from falling away from the torso. The cover may also be provided with one or more pockets (18) to hold nursing pads and the like.

Abstract: Methods of forming crosslinked polymer particles in situ from polymer precursors such as monomers or oligomers, comprising exposing a composition comprising at least one polymer precursor, a solvent or solvent mixture, and an antisolvent or antisolvent mixture to photoradiation under conditions whereby particles are formed are provided. The polymer precursor may be photosensitive, or a separate polymerization initiator may be used. In a preferred embodiment, the polymer precursor is insoluble in the antisolvent or antisolvent mixture and the solvent or solvent mixture is soluble in the antisolvent or antisolvent mixture at the concentrations used. Crosslinked polymer particles and crosslinked polymer particles comprising a polymer and a bioactive material are also provided. The polymer may be erodable, and the polymer particles formed may be used in a variety of applications, including controlled release of bioactive materials such as drugs.
