Abstract: A continuous tube having alternating compositions along a length direction of the tube can include at least a first segment extruded from a first composition along a length direction of the tube and at least a second segment extruded from a second composition along the length direction of the tube in which the first and second segments are integrally joined. Additional segments can be added to the continuous tubing. Such tubing can be used as medical device such as with infusion sets.

Abstract: Junction assemblies for joining intravenous (IV) devices to tubing are provided. A junction assembly includes a component connector and a shaped memory polymer (SMP) member formed of a shape changing material. The junction assembly allows movement of the tube along the component connector when the SMP member is in an expanded state and the junction assembly retains the tube securely against the component connector when the SMP member is in a contracted state. The shape changing material changes to one of the expanded state and the contracted state upon being subjected to an external stimuli. Methods of assembling junction assemblies are also provided.

Abstract: Medical tubing has at least one layer having a composition prepared from a melt blend of (i) a thermoplastic material, (ii) a filler and (iii) a heat reactive coupling agent. The medical tubing can have a kink resistance no worse than a medical tube composed of polyvinyl chloride with the same tubing wall dimensions. The medical tubing can be multilayer and can include single lumen and multi-lumen tubing.

Abstract: The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

Abstract: Bonding dissimilar materials of medical device components can be carried out by applying an adhesive on at least one surface of two components which are composed of dissimilar materials and contacting the surfaces and exposing the contacted surfaces to heat and/or irradiate the adhesive to cure the adhesive and bond the surfaces. One medical component, e.g., medical tubing, can be composed of a non-polar, polyvinyl chloride free thermoplastic polymeric material and the other medical component, e.g., a medical connector, can be composed of polyacrylate, polyacrylonitrile, acrylonitrile-butadiene-styrene (ABS), methyl methacrylate-acrylonitrile-butadiene-styrene (mABS), polyester, and/or a polycarbonate material. The adhesive formulation can include: (a) a polyolefin oligomer having reactive acrylate groups and alkenyl groups, (b) an initiator, and optionally (c) a solvent.

Abstract: A membrane for a medical device includes a first portion having a first material, a second portion having a second material, where the first material is an ionomer, and where the second material is at least one of a thermoplastic elastomer, a thermoplastic polyurethane, and a thermoplastic olefin.

Abstract: Hydrophilic infusion tubes and infusion components are provided. A fluid pathway connects a first fluid port and a second fluid port, the fluid pathway formed of a base material suitable for fluid infusion and a hydrophilic fluid interfacing surface disposed on an inner surface of the fluid pathway. The hydrophilic fluid interfacing surface provides a water wetting contact angle that is less than a water wetting contact angle provided by the base material. Infusion sets are also provided.

Abstract: Medical tube can have a continuous inner layer having a continuous outer layer thereon, in which the inner layer includes a polyolefin such as a polyethylene or polypropylene or a functionalized polyolefin. The outer layer can include a thermoplastic polymer such as one or more of, or a blend including, a thermoplastic polyurethane (TPU), a thermoplastic olefin (TPO), a thermoplastic elastomer (TPE), a styrene-containing thermoplastic elastomer (S-TPE), a polyolefin elastomer (POE), a styrenic blocking copolymer (SBC). Advantageously, the outer layer and/or the inner layer do not include polyvinyl chloride. Such tubing can be used as medical device such as with infusion sets.

Abstract: Co-extruded tubing for administration of intravenous fluids has at least one adhesion layer comprising a non-hydrogenated styrene-based thermoplastic elastomer directly adjacent at a balance layer comprising a hydrogenated styrene-based thermoplastic elastomer. Such tubing can be used to form infusion sets.
