Abstract

A method for manufacturing a medical product comprising a hollow body (2), wherein at least part of a wall of the hollow body (2) is coated at least on the inside with a layer comprising a polymer; at least the part of at least the inside of the wall of the medical product is brought into contact with a mixture (6) of the polymer and the polymer is deposited from the mixture (6) on at least the part of the inside of the wall. And a medical product comprising a hollow body (2) with a wall consisting of one or more structural elements (16), at least a section of the wall being coated with a layer (15) comprising native chitosan, wherein both on the inside and the outside of the hollow body (2) at least some of the one or more structural elements (16) of the wall of the hollow body (2) are at least partly coated with the native chitosan layer (15). And a method for electrodepositing a polymer on an electrode from an acidic mixture of the polymer, wherein the mixture (6) comprises a multibasic acid.
