Abstract: A needless connector is provided which utilizes a resealable preslit septum valve. The valve is resiliently restrained relative to a housing with the valve and housing configured to accept a standard male luer lock having a luer tip which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve includes a disk shaped upper portion covering the opening, a lower portion spaced from the housing and extending downward from the disk shaped portion into a passageway defined by the housing, and an annular skirt to attach the septum to the housing. The connector exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip.

Abstract: The present invention provides a multiple layer structure (10) for fabricating medical products. The layer structure (10) has a core layer (14) of an ethylene vinyl alcohol copolymer having an ethylene content of about 25-45 mole percent, a solution contact layer of a polyolefin positioned on a first side of the core layer, an outer (12) positioned on a second side of the core layer opposite the solution contact layer (16), the outer layer (12) being selected from the group consisting of polyamides, polyesters and polyolefins; two tie layers (18) - one of each adhered to the first and second sides of the core layer (14) and positioned between the solution contact layer (16) and the core layer (14) and between the outer layer (12) and the core layer (14), and wherein the structure (10) is produced in a cast coextrusion process.
