Abstract

1504101 Catheters MEADOX MEDICALS Inc 14 May 1976 [19 May 1975] 20016/76 Heading A5R A non-thrombogenic catheter comprises an outer surface of an unneutralised acidic copolymer of ethylene and acrylic acid having an acrylic acid content of 14-24% by weight, preferably 19% so that the surface becomes negatively hanged on intravascular insertion as the result of a release of hydrogen ions. The catheter may be made wholly of the ethylene/acrylic acid copolymer or may alternatively comprise a coating of said copolymer on a tube of another material which may itself be thrombogenic.
