Bare wire process for making retention catheters

Abstract

Abstract TWO-LUMEN CATHETERS, SUCH AS INFLATABLE CATHETERS HAVING A DRAINAGE LUMEN AND AN INFLATION LUMEN, ARE FORMED BY APPLYING A THIN FILM OF AN AQUEOUS ADHESIVE COMPOSITION, THAT DRIES TO FORM A WATER PERVIOUS FILM, DIRECTLY TO THE INFLATION LUMEN FORMING WIRE. THE FILM IS DRIED TO FORM A WATER PERVIOUS, THIN, TACKY TUBULAR MEMBER ON THE INFLATION LUMNE FORMING WIRE. THE TUBULAR MEMBER IS THEN PRESSED INTO ADHEREING, PARALLEL, ABUTTING CONTACT WITH A LATEX TUBULAR MEMBER PREVIOUSLY FORMED ON THE DRAINAGE LUMEN FORMING ROD. SUBSEQUEBTLY, THE CONVENTIONAL TWO-LUMNE CATHETER FORMING OPERATIONS INCLUDING COATING THE JOINED TUBULAR MEMBERS WITH RUBBER TO BUILD UP A SMOOTH EXTERIOR SURFACE ARE FOLLOWED.
