Abstract
The present invention provides a tubing assembly having a sidewall having a first layer. The first layer is fabricated from a first polymer blend comprising a first component of a material not thermally responsive to laser beam and selected from the group consisting of polyolefins, ethylene and lower alkyl acrylate copolymers, ethylene and lower alkyl substituted alkyl acrylate copolymers, ethylene vinyl acetate copolymers, polybutadienes, polyesters, polyamides, and styrene and hydrocarbon copolymers. A second component of the blend is a laser responsive material having low solubility in aqueous medium; and the blend being sufficiently thermally responsive to exposure to a laser beam having a wavelength within a range of wavelengths from about 700 nm to about 1500 nm to melt upon exposure to the laser beam for a short period of time. The assembly also has an end cap film covering the fluid outlet.
